Over the past year I have been tracking the changes on Western Arc. The past 3 months have had a lot of changes that I posted in the other MPEG2 Western Arc shutdown thread. Now that 129 is (basically) out of commission, here is where Western Arc stands. This is just a national channel list, (no local channels) based off what I can see and what others have contributed. Thanks to everyone who has helped me come up with the locations of some of the channels – I would try and list all of you out, but I know I would forget someone! As has been suggested in other parts of the forum, it would be great to collect the spotbeam data for those who could contribute!
A couple of pieces of info:
- Out of the 64 transponders between 110/119, there are currently 50 transponders that Dish is licensed to use. 22 are Spotbeams, 28 are ConUS transponders (14 transponders are licensed to DirecTV and Dish doesn’t have access to them)
- Those 28 ConUS transponders are divided as follows:
- 10 are dedicated to National HD channels (ESPN, CNN, Disney Channel, etc). Dish is maxing out at 16 HD channels per transponder (note – in an earlier post I said there was one transponder with 17 HD channels, that was an error on my part. When I double checked my listings, one channel changed transponders). Before the transition, there was a maximum of 14 HD channels per transponder.
- 1 transponder is dedicated to adult content
- 2 are a mixture HD PPV Movies/4k channels
- 3 are set aside for HD Sports channels that are only on for live games (NBA League Pass, the PAC 12 alternate channels, some PPV events, etc); 3 SD PPV Sports Channels are there as well.
- 7 are for SD and/or music channels. Dish is maxing out at 26 SD channels per transponder thus far on the SD transponders.
- 5 transponders on 110 I have no channels listed but Dish operates. (they are labeled as ConUS on my chart below) There are other things that could be on those transponders, like RV Distant Networks, internal testing channels, etc, that I can’t see. They might be able to be used for additional content, but I am not sure exactly what is on those transponders.
There are two transponders that have lower than normal SD channels – 110, TP 21 and 119, TP 19. Previously those transponders contained the programming guides that get downloaded from the satellite when the receivers download EPG. I assume that is where the programming guides are still downloaded from, thus less channels there.
When I talk about number of channels on a transponder, all my numbers are unique channels – for example, channel 101 and 199 are the same channel mapped to two different numbers, but in terms of space, only takes up 1 channel worth of bandwidth on the transponder.
Finally, I have to give Dish a ton of credit. When it was 110/119/129, Dish had 82 transponders they were using – it took a lot to get it down to 50 transponders and figure out where all the pieces were going to go. What are the things they did to get there? Here are the things I saw:
- During this migration from 129, Dish converted 7 ConUS transponders on 119 into Spotbeams – that is how they ended up fitting on all the HD locals that used to be on 129. (for those interested, TP 6, 7, 8, 9, 10, 11, 13 are the ones that used to be ConUS on 119 that are now Spotbeam)
- Removed almost all SD duplicate channels that are offered in HD
- Converted remaining SD channels from MPEG2 to MPEG4
- There are also 2 subtle things that changed from the HD channel perspective
- At the beginning of the transition, Dish decreased the number of PPV Movie channels – prior to this transition the PPV channels HD PPV movies were 502-522; now they are 502-517.
- At the beginning of April when MLB, NBA, and NHL regular seasons were all going on at the same time and this transition began, there were a ton of games “joined in progress” for the HD feeds. That wasn’t common since the days before the full time HD RSN’s. The reason for that was prior to the transition, Dish had 4 transponders set aside for HD Sports – 2 transponders was the bandwidth set aside from the HD RSN’s before Dish dropped the RSN’s, then 2 transponders were for alternate channels. Now we are down to 3 transponders for HD sports.
