With the initial buzz over Apple's movie rental operation giving way to speculation about its success or failure, some have cited it as the real next-gen movie format, while others have pointed out some important problems with the current state of online video distribution, warning that big improvements are needed.
While it's probably fair to say there are good points on both sides, the ... [ read the full article ]

Quote:The intent of the H.264/AVC project was to create a standard capable of providing good video quality at substantially lower bit rates than previous standards (e.g. half or less the bit rate of MPEG-2, H.263, or MPEG-4 Part 2), without increasing the complexity of design so much that it would be impractical or excessively expensive to implement.
Isn't Ou therefore correct in stating that AVC can have half the bitrate of MPEG2 but still retain the same video quality? Or am I misreading vurbal's post?
Actually what he says is that the best it can do is keep the same quality at half the size, and if you read closely he also claims that's an exxageration and you need more than half the bitrate for AVC to attain the same quality as MPEG-2.
eatsushi you cannot half the bitrate and expect the same quality. tv's in the US use an 8 pipe system excluding digital witch us the 8+4 methode. there is a pipe for contrast, a pipe for brightness, a pipe for color, a pipe for tint, a pipe for sharpness, a pipe for header information, a pipe for CC, and a pipe for audio,
Mpeg4 is its own format halfing it does not make it Equal to Mpeg2,
Simply put you cant half the bitrate of anything you can however increase the compression.
