Web streaming: wireless or ethernet?

i'm considering getting an apple tv and i have a question for you experts. when you stream content from the web, such as internet radio or netflix, does the apple tv stream directly from its wired ethernet connection or is your computer doing the streaming wirelessly to the apple tv?
i wouldn't want to have to have the computer turned on. also, i get so many drop-outs with air-tunes on my airport express that i would rather stream internet radio without anything being wireless.
this may be a simple question but i don't see an answer anywhere and, not having an apple tv now, i can't figure it out.
thanks.

When you stream content from the web, it goes straight to the web without your PC's involvement. You can go wireless or ethernet to netflix etc. You only need your system for iTunes store and iTunes library content.
Regards.

  • Can anyone help me with compressions for web streaming? So lost!

    Hi there
    I am so confused !
    I have the task of getting HD footage from my camcorder ready for quality web-streaming on a website. The clips need to be in mp4 format using the H264 codec. As we are dealing with HD footage, I want the viewer to be very happy with the picture quality. I must admit that most of my compression settings were kind of guess work and I was only judging my results by the final file size in relation to the video quality. I was getting file sizes of about 16mb per minute of video/ audio footage.
    I had been keeping my frame size at 1280x720 and my bit rates were about 2000-2500kbits/s. Bandwidth is a real concern as there will be alot of people streaming these videos and there might be over a hundred videos on offer at any one time. I found that bit rates any less than this were resulting in a poor picture quality.
    I have since learnt that what I was doing is completely wrong!
    I was told that my frame size was way too big for normal web-streaming of HD footage and also that my bit rate was too high and bandwidth hungry. I never knew that the bit rates I set when compressing my videos would have an effect on the bandwidth that would be used. I am obviously showing my ignorance!
    If anyone has anytime to help out someone who has no idea, I would absolutely love to know the answers to these questions:
    1. What is considered a good acceptable frame size to show HD quality footage? Maybe a size that if the quality is OK, they can also stretch the frame afterwards to fill their screen without losing too much quality?
    2. I want to use mp4 with the H264 codec for streaming, what is an efficient bit rate to set the compression at, so that the quality looks nice, but wont drain my bandwidth unnecessarily?
    3. Can anyone explain how the bit rates that I set for my compressions affect the way they are downloaded once they are on a website. Just cant get my head around this logic for some reason?
    4. What other compression settings should I be aware of (eg. keyframes etc)
    I feel so lost in all of this and would appreciate it tremendously if anyone can help me out.

    If I select a bit rate of say 2500 to compress my videos at, what will that now mean for the end user? Will that mean that his connection will be forced to download that video at 2500kbp/s thus using alot more bandwidth?
    Yes and no. If the end user has a connection that allows them to receive data at 2500 and the source from the web can supply data at that speed then they'll be able to stream in real time. However, if either end doesn't hold up (the client's connection can't receive data that fast or the source can't send it) then end users will be forced to watch it on delay - letting a good portion of the movie download first. QuickTime will do this anyway - if you (as I do) embed a movie into a webpage, when you visit that page QuickTime will calculate how fast data is being sent and received, and decide when to start the movie based on that calculation.
    I was told that the bit rate I set when I compress these files locally on my machine, tell the streaming software how to allow users to download them - is that true or have I got all mixed up?
    You keep saying streaming and I'm not sure exactly what you mean. Streaming can either mean having a finished file on the web that people can watch with minimal downloading in advance, or streaming can mean sending a live event out over the web. I think you mean the first. In that case, there is no streaming software on the server side - it's just a file that gets sent to a client just like any other file. The bitrate however does tell the client software, like QuickTime player when to start playing the movie (As I alluded to above).
    If you really want to "stream" content - in other words allow people to go to page and start watching then I'm going to suggest you distribute in multiple formats. QuickTime has a number of presets you can use for "streaming", and these are usually small (320*240 or 640*480) videos that are under 1 Mbps (often less than 500 kbps). These files can normally be watched in real time by most clients.
    The other catch with the route you're going is that some computers simply can't handle 720p content that is encoded in h.264 - they just don't have the power. If you look at podcasters many of them have chosen to go multiple formats in part for this reason - they have video embedded on their websites for watching in real time, small iPod formats for lower-power computers and iPods, and HD formats for platforms like the Apple TV that offer the best quality.

  • Wireless and Ethernet Network Do Not Work Other Than SpeedTest

    I have been having major problems with my Mac's Internet.  Whenever I connect to my Wireless or Ethernet Connection, the signal start out strong and dies down to almost nothing (around .4 kbps) immediatly.  I have been having this problem for a couple of weeks now.  However, when I run SpeedTest.net, I get the connection speeds which I should be getting.  My Network Application thingy (iStat Menus) shows a major increase from .4kbps to 6MBps when the speedtest in running.  Any ideas on how I can fix this problem?

    It's a router all right. The next question is what is the "downstairs" device? Router or...?
    The Aliant is configured through a browser interface and its IP address ought to be 192.168.2.1. Put those numbers in Safari's URL field and see if its webpage loads. If it does, you might be able to find a setting called "bridge mode".
    Beware that I'm way out in the weeds with this suggestion - changing things in that unit may cause you even more problems. Since you said it is connected to a "wall Ethernet plug" I'm concluding that it should not be acting as a router, but that depends on what is upstream of that wall plug, and what functions the downstairs device is performing.
    If the "wall Ethernet plug" is in fact a phone line and not an Ethernet LAN port then it is your router and you won't want to change that.

  • How do i stream wirelessly from 4s to my LCD television

    how do i use my iphone and connect to an LED 60 inch Samsung television wirelessly

    You can stream wirelessly if you get an Apple TV and connect it to your TV.
    Otherwise, you can as RG said cable directly; what cable you'll need will depend on the inputs on your TV, but HDMI is probable so you'd need this adapter:

    and an HDMI cable.

  • I want to monitor a web stream but it drops out. How can I refresh the web site automatically?

    I work for a radio station that uses a web stream for sports broadcast at various times. My problem is the stream will stop and I have to make a manual refresh to get it going again. I understand there is a way to cause the browser to refresh at a set time I can choose. (such as once ever 60 minutes) I did see this working on one computer but it will not work on the computer I want to use for broadcast. I don't know if it is the version of FireFox I'm using or what? I need help!
    Don Linkous

    This is an about:config option for auto-refreshing. (http://browsers.about.com/od/allaboutwebbrowsers/a/accessibility_blockautorefresh.htm)
    Also try [browser. feedview. timerInterval] & [browser. feedview. reloadInterval]

  • How do I create a web streaming app using digital publishing suite?

    Hello, and thank you in advance. I'm looking for tutorials and guides on how to create a web streaming version of an app using digital publishing suite. Can anyone point me in the right direction.

    Please tell us what you mean by "web streaming." Are you referring to a version of the content that can be viewed in a web browser?

  • ATV stream wirelessly w/o any other additional gadgets but Airport Extreme?

    Hey, I am sure this is probably a stupid question and may have been answered, but I just want to clarify that since I have APPLE EXTREME streaming wirelessly that it will stream to Apple TV without any other additional adapters, etc?? I ask because I own WDTVLIVE and while I enjoy that it plays almost every format, I am having a heck of a time trying to get it to stream wirelessly. I've bought several USB wireless adapters "claimed" to be compatible, but they didn't work. In any event, I am thinking about just purchasing ATV since a working adapter could cost just as much (if I ever find one that works??) if I can get a confirmation that it connects wirelessly as my IPOD, IPHONE, LAPTOP does through my Airport Extreme?? I am correct to assume that it's just a matter of plugging in the device and it should detect my Airport Extreme without any other additional Wireless gadgets??
    Thanks in advance for whomever answers.

    How do you know this if the new Apple TV has not even shipped yet? I was wondering the same thing. I currently stream iTunes media library through Airport Extreme w/Hard drive. If this is true then that would be amazing. I might buy 3 of them for different rooms of my house.

  • Cannot access web-streaming site

    Windows 7 Home Premium 64-bit/SP1 OS...cannot access ANY cahnnels on "FreedoCast" web-streaming site (http://www.freedocast.com)...despite having latest Flash installed (version 11,6,602,180 installed).  Probably not a browser issue as this occurs on IE9, Firefox 19 & Safari 5--of which is a screenshot attached--as you can see No Video--just a Black Screen & No Audio--Basically the same display on all 3 browsers---COULD this be a "Flash" issue or more likely  the actual site (http://www.freedocast.com)--or perhaps something ELSE, I might not be familiar with?? 

    Hi,
    You can check the port you bind for the website in IIS and make sure you have created endpoint with the correct port. You can also install Telnet client on your local computer and run "telnet xxx.cloudapp.net public_port_in_endpoint" at the command
    prompt to see it works.
    Have you enable SSL on the website hosted on Azure VM? If yes, please also create an endpoint with port 443 and open that port in Windows Firewall on the VM.
    Best regards,
    Susie

  • Time Capsule: wireless or ethernet?

    I've got a Time Capsule on my desk, backing up from my MBP wirelessly. It occurred to me that although I like having one less wire, I could connect the two with an ethernet cable.
    My question is: will there be an appreciable difference in speed? My MBP does slow not noticeably sometimes during Time Machine backups, so if an ethernet cable sped that up a lot, it might be worth it. Any advice?

    There is nothing slower than wireless.
    Ethernet would be a great improvement.

  • Exporting for Web Streaming...

    Hello - what are the best specs to export a file for Web Streaming? My client gave me the specs of 640x320, and it's too stretched. Also, would it be in Sorenson? MPEG-4? Something else? Thanks so much!

    But H.264, good to know that that's the 'standard' setting for Web Streaming... ,
    There are no standards for Web streaming. None. H.264 is a convenient place to start but only because Flash will see it and Microsoft's latest products sometimes do.
    Streaming is often confused with but can be wildly different from unicast, multicast, download, and live viewing.

  • File transfer extremely slow in wireless or ethernet.

    Does any anyone know how to improve??

    How is the TC connected to the main router? Is it the main router?
    Descirbe the whole network and how the TC fits in.
    Do not test with both wireless and ethernet at the same time.
    Test from up close.
    Test using 5ghz for wireless within the same room.
    Give us numbers.. we cannot work with slow.. sorry but the issue can be your expections as much as the network.
    Is it slow copying files to the TC pick a single large file and try. Or to another computer on the network??
    Is it just internet?
    More info required.

  • HD or SD Camera for web streaming application

    Looking to buy a couple of cameras (and FCE) purely for creating video for web streaming.
    Given the video will be highly compressed for streaming, is there any benefit in going HD over SD?
    With thanks
    Bob

    CosmoPod downloads the original file format (which can be retained), then converts to either MPEG4 or H264 (Best or Better). The file conversion is dependent on your Preference settings.
    For functional purposes, CosmoPod places a Tool Icon on your Toolbar. Plus, the download/preference panel can be accessed via the Window menu. Videos can be directed to a Download location, or directly to iTunes.
    Whether or not a file can be downloaded depends on file accessibility permissions on the provider's end. Trial version gives you 5 days/10 videos, which ought to give you a sense of whether it serves your purposes.

  • Exporting HDV footage to web streaming

    I'm trying to Export HDV footage to web streaming format but it always ends up stretched to fit the streaming format. any suggestions

    i'm with andy. i've been shooting hdv1080i60 for the past few months for web distribution, but a bunch of the sites/video players that i use don't support 16:9, and if i uploaded the video like that, it would get all stretched. my workaround has been to export>QT movie after i'm done editing, and then make a new 4:3 sequence and drop the previously exported quicktime file in it, and then export>using QT conversion at 320x240 with my normal web settings. it makes the video "letterboxed" but it plays undistorted when uploaded to youtube, google video, etc.

  • Built-in support for web streaming camera?

    Hi,
    I have a Sony MiniDV camcorder that supports web streaming.
    Is there any built-in software support for web streaming?
    If not, could someone please recommend software that will allow me to setup my camera in my house and view the streamed data over the internet?
    Thanks!!
    BT

    You can download Quicktime broadcaster for free to do this. See http://www.apple.com/quicktime/broadcaster/
    We've used it to stream a live event from an art gallery and then to a Quicktime Streaming Server (available free in the Darwin version) to broadcast to the world.
