HEVC (High Efficiency Video Coding)
High Efficiency Video Coding (HEVC) is the compression standard aimed at improving the efficiency of all video streams.
It is a joint ITU/ISO standard that will find applications in multiple video delivery domains, including satellite, cable, over-the-air and over-the-top (OTT), for both linear and nonlinear content. HEVC’s key benefit is bandwidth efficiency, targeting a 50% reduction in bitrate versus today’s MPEG-4 AVC benchmark at comparable video quality. In applications where minimizing bandwidth is not the highest priority, HEVC can be used to significantly improve video quality at the same bitrate as AVC, and is the enabling technology for the delivery of 4K Ultra HD content. In either case, HEVC meaningfully reduces the cost of delivering video versus all other methods, achieving quick ROI. Ultimately, the efficiencies of HEVC mean that it will be used throughout video delivery infrastructures, but this will not happen overnight. Initial deployments will focus on OTT/multiscreen applications where bandwidth is often restricted and the infrastructure is more flexible. Linear TV deployment will begin with IPTV/OTT VOD applications, followed by the broadcasting of live Ultra HD content via HEVC... High Efficiency Video Codec (HEVC), also known as H.265, is the latest video compression algorithm. HEVC is closely associated with the next generation of high definition television known as Ultra HD or 4K. However, HEVC can also be applied to standard definition and high definition video to improve compression rates without compromising quality. The following table illustrates the relative compression levels for MPEG-2, MPEG-4 and HEVC for standard definition, high definition and ultra high definition content. MPEG-4 is typically 50% more efficient than MPEG-2, and HEVC is typically 40% more efficient than MPEG-4. Video Resolution H.262 H.264 H.265 SD (720x576/720x480) HD (1920x1080) UHD (3840x2160) |

HEVC format test is now going on HTV ASIA for SD and HD channels. not 4k test. they may add 4k channels in future. this is what I said. |

RE: HEVC (High Efficiency Video Coding)
MPEG-2 (H.262) SD = 8MP/S
MPEG-2 (H.262) HD = 16MB/S MPEG-2 (H.262) UHD = Not Applicable... MPEG-4 (H.264) SD = 4MB/S MPEG-4 (H.264) HD = 8MB/S MPEG-4 (H.264) UHD = 16MB/S HEVC (H.265) SD = 2.5MB/S HEVC (H.265) HD = 5MB/S HEVC (H.265) UHD = 10MB/S ............................. MPEG-2 (H.262) = SD -8MB/S... HD -16MB/S... UHD -Not Applicable... MPEG-4 (H.264) = SD -4MB/S... HD -8MB/S... UHD -16MB/S... HEVC (H.265) = SD -2.5MB/S... HD -5MB/S... UHD -10MB/S... |
