Re: October is here.. Are those dozen HD channels coming?!?!
Additional MPEG-2 compression is NOT being rejected. In the last year, all HBO and Cinemax HD channels have been transitioned from 2 channels per QAM to 3 channels per QAM using MPEG-2 encoding. In addition, the .TV HD channels have been switched from 2:1 to 3:1 MPEG-2 compression. And most recently, in order to make room for the temporary Olympic HD channels, BBC America HD, and the Spanish HD channels which require MPEG-4 Fios 7000 series boxes, Hallmark Movie Channel HD, QVC HD, MavTV HD and several others have been switched to 3:1 MPEG-2 statmuxing.
The initial batch of channels that were switched to 3:1 statmuxing such as HBO and Cinemax are sent as MPEG-4 from the provider and had to be re-encoded to MPEG-2 anyway. Reported MPEG-4 bit rates were on the order of 6 MB/sec. Placing only 2 of these channels on an MPEG-2 QAM carrier was wasteful. With more channels switching to an MPEG-4 delivery system, look for additional 3 to 1 MPEG-2 channel loading.
If half of the existing HD channels are switched from 2:1 to 3:1 statmuxing, this opens up another another 6 QAM slots, providing between 12 to 18 additional MPEG-2 HD channels. The key is to select the right channel for 3:1 MPEG-2 statmuxing. Shopping channels such as HSN and news channels tend to feature talking heads and less quick action scenes.
