Lose history at end of pause buffer???

I am not sure how long the pause buffer is (it isn't important for this posting), so let's assume for the sake of this issue that it is 15 minutes.
If I am watching TV, and then I get a phone call and hit pause .... and then talk on the phone for 14 minutes and 50 seconds ... walk back into my living room, but don't get to the remote before the 15 minute buffer fills up -- without me touching anything my show/game skips forward to show live TV.  I've just missed 15 minutes of whatever I was watching.
My TiVo (which was GREAT before it died) *and* my DirecTV DVR (which was overall an unstable piece of garbage) would simply start playing from the beginning of the buffer once it was full (so that you'd be 15 minutes behind live TV).  That way if you leave it paused for 19 minutes (exceeding the buffer by 4 minutes), you only miss 4 minutes of TV.  In the case of my FIOS DVR, if I leave it paused for 19 minutes, I miss 19 minutes.
I'm hoping this is simply a configuration option that I can't find ...  I am a very happy FIOS customer, and other than a rare audio drop-out in recorded HD programs (one out of every 10 shows will have 5 seconds of audio missing in the middle), this is the only issue I have.

Yes it has pissed me off more then once. I too have had Direct TV DVR and Dishnetwork DVR and never had this problem. It worked as you stated. But I think it bufferd 1/2hr. Also I have had a program buffered and watching the rest and it just skipped to the live program at the end of the period in which the currenly buffered program was recording. Like it is 6:48 and I walk back to the TV at 6:55 and start watching, WOW what a **bleep**, at 7:00 it jumped to the new live program. Yea I have not been happy, more then once. I have decided that if I am not going to pause it for more the a few minutes, hit record and then play it back from my dvr. Pause will just make you angry.

  • Dynamic history size of xy chart buffer

    Hi all..
    My question is that when I wanna plot dynamic xy graph I should use xy chart. Till here everything is ok. But the option""history size"of xy chart buffer forces me to determine how many points of history data will be displayed. But  what i want is that not fixing it, i wanna see all measurement points till i stop the measurement. thats why i connected to history size option to loop number indicater so that after each measurement i would be able to see all the previos datas till i stop the loop. But it doesnt work!! Does my approach is wrong?

    Sima is right.
    You cannot have an unlimited history size on a computer with limited memory and resources (Yes, even gigabytes is not infinite). If course you can make your own history buffer by growing the x and y data in shift registers, but at one point during run the system will bog down due to constant memory reallocation operations. Also you cannot possible display more data that fits on a typical screen.
    Typically there is some knowledge on an upper boundary, so you can preallocate suitable buffers. If the history is bigger than fits in memory, stream to disk and add some mechansims to browse through history data by reading selected portions back.

  • Cacti graph  lose history after system restore .

    Hi!

    How do I restore history?
    Thanx in advance !

    Hi. Sorry, I know nothing about your "cacti" app, so may not be of much help.
    Did you do a complete system restore (via your Leopard Install disk and Restore from Backup)?
    Or did you use Migration Assistant?
    Or did you restore selected files/folders via the Time Machine interface?
    Did you have anything excluded from Time Machine?
    Did you ever find out from the other forum where (what files/folders) the data is kept? From one of the posts there, it's apparently in a MySql database somewhere?

  • Pause buffer STILL not working

    after how many years now verzion programmers STILL can not get the pause buffer to work when switching between two channels. I pause one station go to another station wait five minutes then go back to the first station and instead of being left at where I pause it I am only behind real time by maybe 30 secs.

    Personally, I've never had the buffer work at all. I only have a single buffer. I called Verizon on this and their "offical" word is that they do not support dual buffers for live tv. This is actually a function of the hardware itself. So how it works now is how its always going to work. Hopefully the new brand of boxes that they are supposed to be getting will have usable dual buffers. Or there is always TIVO and MOXIE.

    Your book may contain photos, that are corrupted, or the iPhoto library may have a problem.
    If the preview is showing all pages correcly, but you still cannot upload the book, try to upload in safe mode, see: Mac OS X: What is Safe Boot, Safe Mode?
    This will disable thrid party software, that might be interfering with the upload.

  • Why replay history data from NI-DAQ buffer?

    LabVIEW 8.6.1f1, NI-DAQ 8.8, Win Vista, two cDAQ chassis.  (I can't move to LV09 or LV10 for this, not yet anyway).
    I have a client with two cDAQ banks, each with 16 TC channels (on 4 modules) and 16 voltage channels (on 1 module), 64 channels all told.
    The config operation is like this:
    This is called twice, with TC CHANNELS and V CHANNELS describing the channel arrangement.  Both channel descriptors are the same except for device number. The Sample rate works out to 1000 / 100 = 10 Hz. I am using CONTINUOUS SAMPLES, with no need for a buffer, but I understand that one is created anyway.
    One loop of my main program is waiting on the READ function:
    You can see the explanation of why the loops are there.
    After reading the data (at 10 Hz), each frame is sent via UDP to somewhere, and every 5th frame is displayed, via another loop.
    This program runs 24/7 on the same computer as another program.
    All this works fine in normal circumstances.
    However, occasionally, a weirdness creeps in:
    In the mornings, after waking the screensaver (or the CPU itself, I'm not sure), we sometimes (not every time) get a very rapid display - the displays are changing much faster than the expected 2 Hz.
    I've been wondering whether the data shown was historical, or simply faster updates of live data.
    Today, it so happened that a blower was turned on just before waking the computer. The device takes 15 seconds to ramp from zero up to operating pressure normally, and then it stays there.
    The readings on screen were frozen (unchanging).  When the computer was awakened, what my client saw was the reading for the blower pressure ramp from zero to running pressure in 2-3 seconds, stay there for 2-3 seconds, drop quickly to zero for 4-5 seconds, and start the ramp again.
    Over and over and over it replayed this data, way faster than 2 Hz.  At least 40 times it replayed this same data, while the real pressure was just variations around the operating pressure.  As time went on, instead of dropping to zero, it would drop to some point on the ramp up and repeat from there.  
    I don't know if it would eventually straighten itself out - the client gives up and restarts the program.  All is well after that.
    I've gone over my code several times, and I can't see a mechanism for me to store this data and re-play it.
    Here's my best guess as to what's happening:
    Since I am not explicitly setting the buffer size, it defaults to 1000 samples.
    Since I'm running at 10 Hz, 1000 samples = 100 sec.
    At some point, because of the screensaver, or because of CPU sleepage, or because of integer rollover, or because of zombie infiltration during the night, NI-DAQ has become confused. 
    When the mouse was wiggled, the gates were opened. After that, whenever I ask for a sample, it gives me one, without regard to read/write position. It continually gives me the next sample from the buffer and wraps around, again and again, and again, as fast as I can read / process / display.
    It is also putting new data into the buffer, so that the historical data eventually gets wiped out.
    That fits the facts:
      It shows only recent (last 100 sec) data, not ancient data, and not live data too fast, as I had considered.
      The data changes with time - oldest data gets wiped out.
      It plays the SAME data over and over and over.
    But that means a bug in NI-DAQ, I think.  
    QUESTIONS:
    Any flaws in my thinking?
    Any previous sightings of this symptom?
    Any ideas for workarounds?

    The rapidly changing data, is that on the viewing machine or on a display on the device acquiring the data?
    The "device acquiring the data" is a pair of cDAQ chassis.  There is no display there. It's the LabVIEW program that is reading and displaying the data.
    Does your computer go into any sort of power saving mode where the USB controllers are disabled during hibernation/standby?
    on MY machine, I have tried this with CPU sleepage and such.  Didn't know you could sleep the USB, but on MY machine, that's disabled.
    But I haven't made it happen on MY machine.
    My CLIENT's machine is actually running XP, and is set to turn off monitor NEVER, turn off hard disk NEVER, and system standby NEVER.
    What version of DAQmx do you have installed?
    On MY machine, it's 8.8 - I haven't found out from my client yet what his is, but it won't be far away from what came with LV 8.6.
    Can you post your code?
    Well, OK:
    Here's two of the loops running (the third loop deals with TCP/UDP and is not relevant, I think).
    The TCM DAQ manager 's READ function is pictured in the original post.
    Here we wait on a sample, scale it (volts into EU), and feed it to the PROCESS TCM DATA vi (which does averaging).
    Here's the NEW DATA function for PROCESS TCM DATA:
    The ST (short-term) HISTORY is set up as an N channel by 5-sample array, and ST HISTORY SAMPLES is set to 5.
    The DAQ loop, after processing this data, triggers a DISPLAY event, which triggers a DISPLAY action, which lands here:
    The GET DISPLAY function retrieves the latest averages:
    That data (64 channels worth) is split into two banks and displayed:
    The display process simply distributes the array data into clusters (channels can be user-configured to be in various locations on the screen):
    The UPDATE TIP action causes a TIP STRIP string to be updated:
    The TIP STRIP shows the average and min and max values (which might be hidden from the display itself), based on which display cell the mouse is in.
    A MOUSE ENTER event on any display cell sets the CLUSTER CONTAINING MOUSE variable to the CTL REF of the event, a MOUSE LEAVE event for the overall display bank (containing 32 cells) sets the CLUSTER CONTAINING MOUSE variable to Not-A-RefNum.
    the DISPLAY looks like this (only a few cells shown).  The display for this program occupies an entire 1680x1050 LCD display, another program runs on the main monitor.
    As you can see, the only storage in this process is the AVERAGER, and that is limited to 5 samples (0.5 sec). It cannot store any more than that.
    I've thought about the possibility of the mouse oscillating between two cells (as mice are sometimes known to do) when it is parked, and causing a flood of MOUSE ENTER events.
    But 1) it happens more often than the odds would dictate  (a random location is not likely to be on a cell border), and
    2)  When that cleared up, the queue would be processed, but it would display CURRENT data more rapidly than 2 Hz. NOT historical data.
    Given that it seems to be about 100 sec of history (judging by my client's recap of what he saw, and how it operates), that points to the 1000-sample buffer within NI-DAQ.  That's the only place that I see to store that data.
    I'll admit that I'm not watching the ERROR output from the NIDAQ READ function. Perhaps I should.
    The only scenario I can come up with is that NI-DAQ's READ pointer is confused.
    When I ask for a sample it tells me that there is ONE and only ONE available.  So I deal with it.
    When I ask again, it tells me the same thing.
    When I ask again, it tells me the same thing.
    It goes round and round the READ buffer.  At the same time, new data is coming in, replacing the oldest stuff.
    But it (apparently) never gets back to the "normal" condition, where it WAITS on a sample at the RAD function.
    Nobody has waited long enough to see if it would do that eventually, after a few minutes (50+ replays), they give up and restart.
    Restarting the program resets the cDAQ drivers, among other things, so the problem goes away.
    If there's another scenario to cause these symptoms, I'm all ears. But I cannot think of it.
    If it was a USB SLEEP problem, I wouldn't think the data would replay from BEFORE the wake-up. But that's what happened.

  • New nano workout ends when paused

    I have a new nano G7 and use it with Nike Plus... When you pause the nano and don't un-pause within 30 seconds or so - it ends your workout... WHY!!! if I need to pause for more than 30 seconds that is my choice.. Can someone please provide a fix or explain how I can overcome this without having to pause/ unpause every 20 seconds so it doesn't stop my workout....

    Hello Rachel_67,
    Using this:
    http://manuals.info.apple.com/en_US/nike_plus_ipod_user_guide.pdf
    I found on page 17 shows the steps to pause, and resume the workout,  but if it ends your work out after 30 seconds of pause there may be an issue with the ipod or Apple is unaware of the software issue.
    If you have one I would do this:
    apple.com/retail and set an reservation to have someone walk you through this.
    or if not, use this:
    Apple - Support - iPod Troubleshooting Assistant
    If the issue persists after that you may want to call 1800 MY APPLE.
    As a side note if does not get fixed, you can go to apple.com/feedback for a feature request.
    Hope this helps.

  • I have installed firefox Aurora, but can I uninstall it and go back to Firefox 11 if I find version 11 better? Will I lose history and bookmarks?

    I have installed the new version 13, called Aurora. I am currently using it, but if I start not liking the new features (so far I do! But I have to ask) can I "go back" to the "good old" Firefox 11?
    Will I be loosing my data and settings? History and bookmarks?
    My computer is a Pentium M 1,6GHz (2004.) and the version 11 seemed very stable. The reason I installed Aurora is because I wanted to try your new software.

    Also, before you go back to an older version (transition from Aurora to Release), you might want to back up your bookmarks and such. Usually, an older version of Firefox will be able to read your data, but this is not guaranteed.

    all my sites lose their sign in  when i delete history at end of the day when i have yosimite. Befoe i loaded new OS when i removed JUST the histories i didnt have to sign in the next day in mail or yahoo ore any other sites. Yosimite clears all my histories as well as the data . Is there a way just to clear histories.Its a pain in the neck to sign in again for all my sites.

  • Video loses sound then pauses

    Hello everyone! I've recently encountered a problem in watching videos online. The video works well at first then after a couple of minutes it suddenly loses sound and then it pauses, this occurs randomly until the video is done. no matter which site I go this always happen. If anybody can help me I would really appreciate it. Thank you.

  • Is it possible to cache the updates of history, permissions, forms etc, and write them to disk only at exit?

    I noticed that Firefox updates instantly the places.sqlite database on disk, with every new page load.
    I suppose this is done to maintain the History complete in the event of a crash.
    The same thing happens with the permissions.sqlite and formhistory.sqilite.
    However this constant updating generates a lot of disk writes which may shorten the life span of SSD disks.
    Is it possible somehow to force Firefox to only update the various Profile databases at exit?
    Knowingly incurring the risk of data loss when crashes occur.
    I have disabled session restore and the recently closed tabs, among other things, so that's not the reason behind the constant updates.
    I am seeing this on a windows XP 32-bit, but it is probably the same on any system

    I suppose you could monitor those files. The add on SQL Lite manager allows you to open the databases of history. You could also clear history on end, or just browse in a private window all the time so it remembers nothing to save disk writes, but that is really silly. Please ignore that.
    I do not think there is a way to do that currently.

  • Strange issue when pausing LONG audiobook--pressing play again changes the

    Strange issue when pausing LONG audiobook--pressing play again changes the position within the book--it doesn't start back exactly where it left off.
    The audiobook of "Harry Potter and the Half Blood Prince" is between 18 and 19 HOURS long--all as one long track/file.
    I've noticed that when I pause while listening and then press play again, it "rewinds" and starts playing portions of the audiobook from about 10 minutes prior--but the time stamp doesn't change. At least this is the time frame from the first "test". Other pauses/plays may result in different time differences.
    The first time this happened, I didn't realize what it was doing. I pressed play (from the pause) and I heard a portion that I had already played. I thought that the bookmark just didn't "remember" as it should have, so I scrubbed forward trying to find where I remembered leaving off. If you end up pausing/playing even a couple of times with this happening each time, the portion of the audiobook that you're playing and the time stamp becomes COMPLETELY off! For example, almost an hour into the time stamp was really only about 10-15 minutes into the actual book.
    I'm not sure if this makes any sense, but hopefully it does to someone. It's very frustrating to have this happen simply because you had to pause while listening. You have to scrub backwards or forwards each time to find out where you REALLY left off at and the time stamp becomes of no help value since it doesn't change as the playback position moves itself.
    I'm sure that this is something happening due to the extreme length of the audio file. That maybe it can't track as precisely as it could with shorter lengths. ???
    Any ideas? Has anyone else seen this happen? Any ideas on whether or not there is anything that can be done to prevent this?

    I'm glad that I'm not the only one having this
    problem. It's ironic that we're both having issues
    with the SAME audiobook. I haven't had a chance to
    listen to Books 1-5 much to see if they have the same
    issue or not--I don't remember any on the few parts
    that I've played for my nephews.
    Yeah, I know! I was shocked to see that. I recently finished HP5 (twice), and NEVER had this issue, but it is a much smaller file size.
    I'm thinking that I may try to convert to AAC before
    I try the splitting program--in theory, it's easier
    to start right back in again when you only have 1
    track to find, than when you have dozens/hundreds of
    smaller tracks. It's sometimes hard to remember
    which track you left off with--even if it's
    "bookmarked" within that track.
    I dunno anything about AAC, to be honest. Never used it. My plan is to split the MP3 into smaller MP3s by chapter and load them on a playlist. Of course, I will have to label them all nice and pretty. It is a long book, but you could always just load a couple of chapter files at a time. The only thing that I can see that would be kind of a pain about splitting it with the Cool MP3 is searching thru the file for each chapter and setting break points.
    My only concern is how much quality I'm losing by
    converting from one compressed format--MP3--to
    another compressed format AAC.
    Yeah. Ew. No clue. Sounds unpleasant to me. Again, I really do not do anything with AAC.
    I suppose, since it's
    spoken word instead of music, the change shouldn't be
    too noticable. I'm not sure what kind of time frame
    it'll require to convert. I'll probably try it with
    book 1 first--since it's the smallest.
    May depend on the program. The one I got boasts no quality loss. You may wanna scrounge around the download sites and see which one sounds like it has the best features, even if you do just get a free trial version of something. I would definitely read the editor's ratings. I tend to trust that more than the typical end user's. They show how many stars the editor gives a product, and you can click that for the review, or sometimes they have labeled tabs where you can access the review.
    As for how long it takes me to rip that particular file and if that actually fixes the scrubbing problem, I will have to let you know tomorrow. WAAAAY past my bedtime!
    Keep me updated on your end. I sure which that there
    was an explanation for why it happens.
    Will do! I am thinking you hit the nail on the head with the length. That was exactly what popped into my mind when I figured out what the goofy thing was doing.
    Talk to you later!

  • "Buffer Utilization" in DataSocket Connections ?

    I am setting up a test situation using DataSockets.
    It will eventually be used between a host, and an RT board, but for right now, it's all in one VI.
    I use DS Open, DS Write, DS Read, and DS Close.
    I want the connection to buffer my data, as the two ends will run anynchronously.
    The URL I use is:
    dstp://localhost/XXX
    Here's the sequence of events:
    DS OPEN (BufferedReadWrite) (the sender end)
    PROPERTY Write(BufferMaxBytes=1024, BufferMaxPackets=10)
    DS OPEN(Buffered Read) { the receiving end }
    PROPERTY Write(BufferMaxBytes=1024, BufferMaxPackets=10)
    DS WRITE(Sender, 1)
    DS WRITE(Sender, 2)
    DS WRITE(Sender, 3)
    DS WRITE(Sender, 4)
    DS WRITE(Sender, 5)
    DS READ (Rcvr) ==> Display 1
    DS READ (Rcvr) ==> Display 2
    DS READ (Rcvr) ==> Display 3
    DS READ (Rcvr) ==> Display 4
    DS READ (Rcvr) ==> Display 5
    DS CLOSE (Sender)
    DS CLOSE (RCVR)
    So that's the basic sequence. If I set the MAX PACKETS property down to 4 or 3, I get only the latest 4 or 3 values, as expected. Fine.
    But I would like to use the BUFFER UTILIZATION property to tell from the sending end whether the buffer is nearly full or not.
    PROBLEM 1:
    The BUFFER UTIL(Bytes) property does NOT report a number of bytes, but apparently a fraction of the MAX BYTES I specified.
    PROBLEM 2:
    The BUFFER UTIL(Packets) property does NOT report a number of packets, but apparently a fraction of the MAX PACKETS I specified.
    PROBLEM 3:
    No matter where in the sending chain I put a property node to read the buffer utilization, it always reports 1/N for the packet utilization, where N is the MAX PACKETS I gave it. If I set MAX PACKETS to 10, it reports 0.1 after opening, 0.1 after the first write, 0.1 after the 2nd write, and 0.1 after the last write. It doesn't matter if I overflow the thing or not.
    PROBLEM 4:
    If I put a property node in the receiving chain, I get weird answers, as well. with MAX PACKETS = 0, I get 0.4 after the 1st read, 0.3 after the 2nd, 0.2 after the 3rd, and 0.1 after the 4th. Fine.
    But I get 0.1 after the FIFTH read (the buffer should be empty).
    And I get 0.1 before the FIRST read (the buffer should be half full).
    The Utilization in bytes is similarly useless.
    Anybody know what I'm missing?
    Why isn't this property more meaningful?

    Blog for (mostly LabVIEW) programmers: Tips And Tricks

    I did figure out some things about this:
    #1 - #2: You can set two limits on the buffer size - if you set a limit of 10 packets, then even a megabyte buffer is full at 10 packets. If you set a limit of 100 bytes, then even a million-packet buffer is full at 100 bytes. So you can look at the "fullness" in either terms, depending on what you need to do. That's contrary to what I was expecting from the terminology, but I understand it now.
    #3: Deep down in the help text, I found out that the property only works from the READ end. After thinking for a while about it, this too makes sense, since the READ end might be very distant from the WRITE end, so for the WRITE end to know about the status of the READ end would require lots of feedback. That
    means lots of reverse net traffic in some cases (not in mine).
    #4: the statement "And I get 0.1 before the FIRST read (the buffer should be half full)." was in error. When I verified the timing of things, the first status report did indeed indicate a 0.5, not 0.1. My bad.
    #4: WILD GUESS: the never-going-below 1 sample problem is actually indicative of the fact that the DS READ operation will return a value every time (after the first one). If there is no new value, it will return the last value it read some previous call. That messes up the actual counting of values in the buffer, but there it is.
    I ended up reporting the buffer status from the READ end back to the caller (along with other results going back), and letting the WRITE end use that number to judge whether it should write more data or not.
