From Wikipedia... ] MLB Network HD MLB Network HD is a 720p high definition simulcast of MLB Network, which launched simultaneously to the regular channel. All studio programs are shot in HD. The network is also currently remastering 30 World Series Films in high definition. [7] According to a December 15, 2008 Broadcasting & Cable article: After much discussion, MLB Network decided to use the 720p format instead of 1080i because it believes 720p shows the motion of baseball more accurately and will degrade less when recompressed by cable operators to save bandwidth. As Mark Haden (VP of engineering and IT of MLB Network) says: �That's our best shot of maintaining quality to viewers.� [8] The 720p format is also used by MLB broadcast partner Fox and many of the Fox Sports Net regional sports networks (which hold the rights to local game coverage of several teams), along with ESPN. DirecTV carries both SD and HD.[9] Verizon FiOS has also come to an agreement with MLB to carry the MLB Network in SD and HD[10]. Cablevision has announced they will carry the HD version. [11] Some Time Warner Cable systems do as well. Their decision to go with 720p format sounds interesting , I'm no expert though and to me 480i , 720p and 1080i/p are good selling gimmicks. SNY & YES use 1080i on their broadcasts . I read recently in a trade magazine that with a HD TV and a BlueRay DVD you can get true 1080p.
