H.265 High Efficiency Video Coding (HEVC)

To satisfy a growing need for higher coding efficiencies for standard definition TV and video transmissions over low data rate channels, in the early 2000’s H.264/ MPEG-AVC standard was developed. During the late 2000’s H.264 entered into additional developing efforts to further improve the coding efficiency as well as integrate functionalities and features in to H.264 design. Although H.264 succeeded in improving coding efficiency compared to its predecessor ultimately H.264 was not initially designed for high definition transmissions.

H.265/ MPEG-HEVC standard was designed to be compatible with H.264/MPEG-AVC applications while focusing on high definition coding. H.265 with the new HEVC (High Efficiency Video Coding) standards brings promise to CCTV with bandwidth saving of about 40%.
While H.265 is promising and can bring consumers quality video at more efficient bit rate times adopting this technology could still be a couple years away.
Significant investments need to take place, H.265 is much more processor intensive, that a simple firmware update is not how you can acquire this technology. A hardware decoder needs to be in place, and that is where part of the problem lies.
H.265 is an advantage and will greatly improve HD video quality and bandwidth usage but this will only happen in due time as manufactures and industry leaders begin to invest in upgrading their video player hardware to the new HEVC standards.
