Digital video is in the process of getting another major haircut — a development that promises to provide tremendous relief for bandwidth-constrained mobile networks, as well as for the delivery of ultra-high-definition TV.
The High Efficiency Video Coding specification, also referred to as H.265, will be even more efficient than H.264 MPEG-4 Advanced Video Coding. HEVC-based commercial products could arrive starting in 2013.
According to industry experts, HEVC could shave off 25% to 50% of the bits needed to deliver video that looks as good as H.264.
“It seems like every decade we come out with a better compression standard,” said Sam Blackman, CEO of video-processing systems vendor Elemental Technologies.
HEVC is being designed to take advantage of increases in processing power in video encoders and devices. The developers of H.264 had elements they wanted to include, “but the computational costs were considered too high 10 years ago,” Blackman said. “You’ve also had research over that time to improve the standard for the next time.”
