At last week’s CPSE Beijing, TVT showcased its newest technology – H.265 series products.What is H.265 ? How can it change the video surveillance? Let us reveal the myth today.
What is H.265 ?
H.265 is a video compression standard, a successor to H.264, also known as High Efficiency Video Coding, HEVC
This video compression format delivers crisper network video contents but just requires about 50% less bandwidth for the same image quality as H.264, making it easier to download or stream HD video.
H.265 was designed to significantly increase coding efficiency compared to H.264 – that is, to reduce bit rate requirements by half with comparable image quality. Depending on the application requirements, H.265 encoders can mitigate computational complexity; improve compression rate, robustness and error correction; and reduce encoding latency.
Why H.265 superior than H.264 ?
H.265 can double the data compression ratio compared to H.264 at the same level of video quality. i.e. H.265 delivers the same or better image quality than H.264 with bit streams reduced by 33%~50%(This result may vary with different conditions .)
H.265 provides substantially improved video quality at the same bit rate as H.264. It can support 8K UHD and resolutions up to 8192x4320.
More stable video transmission
Nowadays HD trends are everywhere,but limitations of the H.264 standard have begun to emerge -- Network bandwidth and storage equipment usually cost a lot for a surveillance system. Since H.265 compression efficiency is improved by about 50% over H.264, it can result in almost 20% investment savings, ensuring higher performance and lower network and system building cost in video surveillance.
