This Thursday morning at approximately 6:00am EST there will be some changes in HD in format they are delivered.
The following channels will go from MPEG 2 to MPEG 4.
206 ESPN HD 209 ESPN2 HD 245 TNT HD 281 HD Theatre 501 HBO HD 543 Showtime HD 259 Universal HD
Some folks believe these channel locations were already broadcast in MPEG4, but they were not. They required the MPEG4 receiver but were still broadcast in the MPEG2 codec. (I'm not an engineer so forgive me if I'm stating that incorrectly).
This should not effect any customer that is already seeing the above channels in those channel ranges as they already have a KaKu dish and MPEG4 equipment. The only difference is that those channels will be in MPEG4 now instead of MPEG2.
Customers that do not have the correct equipment will still be able to see those channels in MPEG2 in the 70-99 range for the time being.
In addition, the following channels will get their MPEG 4 channel location on July 31st. These will be in Ka (again, need the KaKu dish)
