I don't think the problems are from the transmission; I think they must be in how the VIP handles the CC data streams. In the earlier post I listed two dish HD channels (Discovery and HBO) that had no CC or broken CC display on the video signal coming out of the Vip box. But if I viewed the CC on the same channels a minute later but via TV2, they were fine.
Surely the Vip takes the raw CC stream it has received and pumps it out though the TV2 connection. My connected TV then processed the CC and showed the captions fine. Same channel, different software/hardware processing devices. One works, one doesn't. I'd say the Vip software is broken.
NO, TV2 and TV1 are 2 different beasts with CC. I have been fighting with Dish on CC on the vip622 for over 2 years!
As dschneider suggested to you guys, I have also filed a complaint with the FCC over 2 years ago about this issue. I have been in direct contact with dish engineers, and even had hour long phone conversations with the director of engineering on this issue.
Here is the info I got out of Dish.
CC on TV2 will always work fine as it is a direct SD output. i.e. normal old Tv, CC has always been line xx of the video feed, so it is always there and always decoded by your TV, NOT the dish box, so that works and always will work.
Now, the feed going to TV1 is an HD output of the dish box, which bypasses your HD TV's tuner, so the decoding must be done by the dish box.
Here lies the problem. In the HD video feed, the CC is no longer line XX of the video feed, so it took a while for them to get it "right". Also to make matters worse, the standard was different for different HD resolutions.
For 720p it could be on line ww or yy, and some channels chose ww to feed it in , and some channels chose yy to feed it in.
ABC is a 720p feed, not 1080, so they were always the worse, especially 2 years ago when HD really started. Dish has caught up a bit, and it seems better now a days.
I still get the issue today where the CC feed will go away on it's own, ( I have not spent the time to track this one down like I have with all the other issues I reported to them.) When it does go away, it will not come back until you reboot the controller.
Nice thing to have to do when you sit down at 8:30 at night to watch a recorded show from last night, yet you are currently recording a show, so you can't reboot it since it will screw up your recording, and you can't watch the taped show due to hearing impairment, as there is no CC.
Frustrating out the wazoo, yet those who use CC are the minority, so it is low priority at Dish.
Anyhow, I was told that when the CC goes away completely that it was an issue with the firmware in the CC decoder that hicups the decoder and it goes braindead until rebooted. I was also told that the CC decoder is provided by a dish vendor, not dish, and that they were not sure if it could be fixed in a software update, or not.
For me with the vip622, the food network, and TLC are the WORST for CC.
Usually non existent, or if you watch the show for 3 minutes, then it starts, then you can rewind back to the beginning of the show, and the CC is there.
Very frustrating, especially with what we pay per month, and especially since they confirmed with me that "Yes CC works with that receiver" BEFORE i ordered service with them 2 years ago.
