Efficiency Video Coding (HEVC), H.265 is a new video compression standard, which produces videos of the same quality as H.264 yet taking up only half the bandwidth.
H.265/HEVC is critical for streaming high-quality video even in congested network environments, and will be a driving factor in the delivery of 4K content to new Ultra HD displays.
H.265 has better compression performance and lower bandwidth utilization ratio.
For video services, the ultimate goal of compressing a movie is to reduce the size of the movie file, so as to take up less storage space, as well as drop the network bandwidth consumption in transmission.
Compared with H. 264, the greatest strength of H. 265 is that it has a higher compression ratio, which can be discerned from its name. H.265 is also called HEVC (High Efficiency Video Coding), and the primary use is to further reduce the design flow rate, in order to lower the cost of storage and transmission. At the same quality of coding, H. 265 can save around 50% of the bit rate, and coding efficiency can be doubled than H. 264. As H.265 provides more different tools to reduce the bit rate. For example, in H. 264, each macroblock is fixed to the size of 16 x16 pixels, but the coding unit of H.265 can be chosen from a minimum of 8 x 8 to the maximum of 64 x 64.
H.265 implementation has generated huge optimism given industry’s struggle with shortage of bandwidth, spectrum, storage, and imminent need to take growing HD content for multi-platform delivery. It can result in 20% investment savings, ensuring higher performance and lower network and system building cost in video surveillance. Implementation of the new format in video surveillance is “inevitable.” It will be a significant development for the future technological growth in HD surveillance.As HD 1080P TV broadcasting and 4K video streaming with H.265 are already possible, we are cautiously optimistic about the future of the H.265/HEVC standard. Therefore, MountXross will introduce H.265 products.
