Unsmooth ticker/marquee movement?

Hi All,
I am a newbie in JavaTV and trying to develop my first Xlet application, a ticker/marquee, with MHP.
I found that the ticker sometimes stopped (like a jitter) in its movement when running on real STB, it confuses me for days and still dont get how to fix it. Can anyone suggest?
Yes, it runs well on my emulator with PC.
I guess it might be caused since the XLET is running on MHP middleware and some part of the MHP is running with other process(such as collecting SI/PSI from broadcast network). But the guess is not accept by my adviser since he suggest I review my code to solve it.
Can anyone help on it? (agree my opinion or dis-prove it ... ).
I have referred to the sample code in this thread. However, it just jitters sometimes.

replied by myself...
After checking w/ the box manufacturer, we have some findings.
The marquee program is always switching among the stages of 'sleeping' and 'awake'. The 'sleeping' stage might be sometimes extended due to STB is unable to finish its sleeping in time (due to cpu time competition). STB with MHP middleware is an embedded system that usually equips only with minimum computation power, (cost and some other design consideration). Thus the programmer should not expect it is a powerful computation environment and being able to response every single request in time(or as it behaves on emulators running on a pc). We are now doing work-around to adjust the program presentation so that the 'jitter' could be hardly 'seen' by the users.

XML driven message ticker (marquee)

I'm makin a scrolling marquee that gets its data from an xml
file. It reads it in and displays it fine, however, each loop of
the scroller I want it to read in the xml file again so that any
new entries will be displayed.
I don't know if it's caching the xml file or what. I've tried
the usual addition of a random query strong on the end of the xml
file but still get the same data in.
Any ideas?

than the random query string is not set correctly because if
it was, you wouldn't be
getting cached file.

Probably because photo stream only keeps photos for 30 days, even though they remain on your devices (up to 1000 photos) until you delete them. These photos are probably the ones added in the last 30 days. To view the others, you can either create a shared photo stream with the others and invite yourself, or you can open them on your device and use AirPlay to stream them to your Apple TV.

This works fine and I would like to include some dynamic content into this script. Either some page iteme content or even some query results. My java script knowledge is quite "skinny" so I got to ask how to do that?
Thanks in advance,
Denes

Denes,
I just came across your thread.
Just replace within
var marqueecontent='<nobr><font face="Arial"><b>This is where my text goes.<b/></font></nobr>'...
the: "THIS is where the text goes." with: &P1_text.
and you can manipulate the text dynamically.
Ofcourse you hv to create the item P1_text and shortly after you keyed in s.th. and push "Enter" - then the data is in the Session (look at Session in Developer bar).
After "Enter" the ticker/marquee works with your data.
Alternative 2:
Define in Application Attributes under Static Substitution Strings a "GLOBAL_ITEM" with a value: say: my News - then replace &P1_TEXT. by &GLOBAL_ITEM. (beware of the '.' after the item !!! it has to be there !!
Alternative 3:
Work with a table:
A)Define a table called "NEWS" with the fields News_id, text, active_inactive - work with sequence..
B) Define form and report for data entry. In the form go to the item "active_inactive" and modify iot to be a radio-button with LOV : STATIC: Yes,No
C) still use the item P1_text and in the attributes of the item go to "Source" - select "SQL-Query" and key in:
select text from news where active_inactive = 'Yes' - modify the P1_text item as "hidden"
--> now you can manage your news and just the "Active" news are shown.
Advanced: make sure, that only one record is active !!
Have fun !! (:-)

How to use ticker

hi,
i have a query which is having three fields.
i want to display values of these three fields in the ticker
so i added one form and selected ticker.
now how how to assign this query to the ticker so that i can display all the three fields data
example
matno matgrp matprc
m001   a          100
m002   b          200
m003   c          300
i want ticker to move in this way
m001   a   100 m002   b   200   m003   c   300
how to get this
please suggest me
Edited by: venkat s on Jan 30, 2008 7:00 AM

Hello venket,
It is possible. Let me take your example.
matno matgrp matprc
m001 a 100
m002 b 200
m003 c 300
m001 a 100 & m002 b 200 & m003 c 300
Try this to add space between 2 entries,
m001 a 100 &" "& m002 b 200 &" "& m003 c 300

Can't download iTunes purchased movie to my iPhone

I can see the movie there in my recently purchased section.
I connect the phone, tick the movies I want to download then press 'apply"
But then I get this message:
My phone isn't synced with another library. This is the only one I use.
I've updated software etc and can see everything there on my library but can't get the movies!
Any ideas?

You need to buy and install a Mac OS X 10.6 DVD, and then run the 10.6.8 combo updater.

Marquee Widget Not Working

My Marquee Movie Theatre Listing Widget has stopped working in Tiger 10.4.11.
Initially, when I changed the US ZIP Code to another US Zip Code, it continued to show the movie listings from the first ZIP code. I also tried changing the US Zip code to a valid Canadian Postal Code. Still no luck.
I also deleted the marquee PLIST file. Still no luck. The PLIST was recreated. But now I see NO listings at all.
Any ideas on how to fix this?

Yes, I thought it was an Apple supplied widget. But it looks like I was mistaken. I am referring to Marquee 1.0.4 Movie Listings Widget. It was working but it stopped.
Unfortunately, it also looks like the software developer has gone out of business.
If anyone knows of a fix, please let me know.
(Or if there is an alternative Widget for Tiger that does Movie Listings, please let me know!)
Thanks

DVD from Animations - Help please if you can

We have an 3min animation sequence that needs to be put to DVD.
Animation was created in Maya, it's a 3D building walkthrough, constant movement.
It is supplied as AVI (video track is WRAW) 720x576 (for PAL)
We have placed it on FCP sequence set to Animation, best, millions colours, keyframe every frame.
Sent to compressor - 8Mbps CBR, best motion, GOP size =7 / Structure =IBP, closed.
The resulting M2V looks fine in QT
It also looks fine in DVDSP Simulator
However the DVD created (from an image) both in Apple's DVD player and on set top players looks badly pixelated, grainy and flickery.
Is there something in the make up of the animation that doesn't suit DVD playback? Why wouldn't we see it in the Simulator?
Any help greatly appreciated.

Thanks Colin,
I have exported the supplied file as QT movies using different QT Codecs, DV PAL, Animation, Motion JPEG, also DV stream. If the option is there I have set the field order to Lower first. I have also imported the supplied AVI to FCP onto sequences with differing compression settings as above. All produce the same effect.
I have exported the AVI from QT as an image sequence, once as is and once with the deinterlace ticked in movie properties and imported each image as a frame to FCP onto a DV PAL timeline, this you would think would work around any issue of field order and behave as the sequence settings dictate? I get the same result, the final DVD image looks fine in DVD Player, unless you UNTICK "deinterlace" (which is wierd in itself), then it flickers badly, as does a DVD written from the image.
The best result I have had so far is following your instructions (thanks) in another post for 24fps NTSC, the final DVD was not flickering anywhere as badly but motion overall was a bit jittery. Is there a work around for animation like this with PAL do you know?
Also - maybe this might be a clue?
When I have the clip looking fine in FCP as a DV clip or image sequence on a DV timeline, with the play line stopped or running, the Canvas ONLY looks good at 100%, anything smaller or larger creates this striping moire effect on the image, visible even with the play line in stop.

New to Photoshop and want to add text to a photo. I want to create a text box that has a masked background( I think it is?) Where the text is laid on a (color of choice) in the text box. Then then the Text is typed on that masked portion on the pic... I know how to do this in Photoscape, and Win7 photo editor, however I cannot find the tool to add white background behind my blue text...F1 unrolls every rabbit hole in Cs6 wich one must know the exact phrase to find it.
Thanks
Netcommercial

after loading up photoshop you file > open > and load in your photo, or you open photoshop and then simply drag in the photo into the work area.
that done you then choose the shapes tool, every tool when hovered over shows you what it is. most tools also have a little arrow on so if you left click and hold a choice appears. Most if not all of the tools look like what you want it to do. the eraser looks like an eraser, the text has a letter T on it, 2 icons down from that is the shapes tool.
Choose your rectangle or whatever
on the toolbar at the top when you chose a tool, your options change. So if you choose the text tool, then the top toolbar changes to allow you to choose the size of the font , colour etc.
after choosing your rectangle the 2nd option on the toolbar says path , shape or pixels
the 3rd icon up on the tools is the foreground and background colour.the front icon of the 2 is the foreground clicking that icon will allow you to change that colour.
choose shape and then click and hold the left mouse button on the photo where you want the top left hand corner to be, then hold and drag it down to the right hand bottom corner. It should then fill a shape, whichever you chose , with the colour whichever you chose. but also it will auto create a new layer as you chose shape from the three choices.
the next step is now go to the text tool, ( the T icon on the tools ) , the toolbar changes to allow you to change the font , and size and colour.
type in your text, the commit it, by pressing return or clicking the arrow that appeared on the toolbar to confirm you want it.
and thats it all done. the only thing to do now is move things around where you want it, this is done by selecting the layer you want, so shape layer, or text layer, from the layers pallette, which is that whole bunch of panels on the right. If you do not see layers then go to the top toolbar where it says file edit image layer etc, and choose window, when it opens make sure layer is ticked.
to move stuff and and resize etc, you need to on the move tool, which is the top icon, arrow with plus sign with arrows, again looking like what you need to do.
so select hat tool, then go to the layer you want to move, shape layer or the text layer and automatically you will see the transform handles, 9 little square nodes. when you hover over any of them the mouse icon change to show you can stretch it to make it fatter or thinner.
if you hover just off and of the corners of those transform handles the icon will change to a rotate icon allowing you to rotate the shape.
i may have slightly over complicated it by giving you more choice and explaining the terms. but all the info you need is in here
the final step SAVE
