New compression standard could be in commercial products as early as next year

The Moving Picture Experts Group (MPEG) met recently to issue a draft international standard of a new video compression format offering twice the performance of current standards. The new video compression format is called High Efficiency Video Coating or HEVC. The new H.265 compression codec is roughly twice as effective as the current H.264/AVC standard.
 
“There’s a lot of industry interest in this because it means you can halve the bit rate and still achieve the same visual quality, or double the number of television channels with the same bandwidth, which will have an enormous impact on the industry,” says Per Fröjdh, Manager for Visual Technology at Ericsson Research, Group Function Technology, who organized the event as Chairman of the Swedish MPEG delegation.
 
H.265 could usher in ultra high definition television with significantly more clarity than the 1080p we have today. The new compression format will also significantly reduce the bandwidth required for streaming video on mobile networks where wireless spectrum is at a premium. The format will pave the way for wireless carriers to offer more video services within the confines of their available spectrum.
 
“Video accounts for the vast majority of all data sent over networks, and that proportion is increasing: by 2015, it is predicted to account for 90 percent of all network traffic,” Fröjdh says.
 
He believes that the HEVC format discussed during the meeting in Stockholm could find its way into commercial products as early as 2013.
 
“It will take time before it’s launched for a TV service, but adoption is much quicker in the mobile area, and we’ll probably see the first services for mobile use cases next year,” Fröjdh added.

Frame Rate

Because of the "persistance of vision" phenomenon, 24 frames per second is enough for static images to eliminate the "flicker" phenomenon. But when portions of the image have moving objects, they will lose dynamic resolution (get blurry). For many scenes like well-lit indoor soap opera sets, this is often difficult for the viewer to detect. But camera panning of many scenes is very easy to detect at low frame rates because everything in the scene is moving.

Next time you watch a football game, pay attention when the camera man pans the audience on the opposite side of the field. At a very slow camera pan, the audience gets very blury. The same effect happens in nature scenes like mountain landscapes. I hate these artifacts and have wished for higher frame rate for decades. 60 frames per second produces much greater dynamic resolution than 30. Sports has a lot of action, which requires more dynamic resolution than soap operas, and is why ESPN broadcasts in 720p60 instead of 1080i30. 720p60 also promotes better slow motion playback.
