What is the difference between H.264 SVC and H.264 AVC?

What is the difference between H.264 SVC and H.264 AVC? Be AVC is actually an alias of the H.264 protocol. However, since the SVC part of the H.264 protocol, people habits will be called AVC, and the SVC is separately referred to as SVC. So when mentioning AVC, it is necessary to determine the part of the H.264 protocol or the part of the protocol is not included in the agreement; Be SVC is Scalable Video Coding, some translated component layers, and some translational components. H.264 / AVC is a new standard for JVT to develop video encoding. The H. 264 extension standard supports a variety of graded types, with the airspace to be graded, time domain, graded, and quality graded is a typical representative of a graded mode. The codec of JM86 is based on AVC, and the codec of JSVM is based on SVC. Be Be H.264 SVC (H.264 Scalable Coding) As an extension of the H.264 standard, the initial starting by JVT in 2004 and obtained ITU approval in July 2007. Based on the H.264 AVC video codec standard, the H.264 AVC video codec standard is used, and various high-efficiency algorithm tools of the AVC codec are used, and the encoded video time (frame rate) generated (frame rate), the space (resolution) Expand, and is scalable in video quality, which can produce decoded video of different frame rates, resolution, or quality levels. The H.264 SVC implements the graded graded reference frame implementation in the GOP (encoded image group). 0-16 Video frame constitutes a full frame rate video, all video frames except T3 flag constitute a half frame rate video, all T0 flag and T2 flag video frame constitutes a 1/3 frame rate video, all of which is just a T0 flag The frame constitutes a 1/4 frame rate video. SVC Time Scalability SVC Space Scalable H.264 SVC is classified by a subsidiarcharging of a plurality of different resolutions having correlations in encoding symbol streams. All of the upper video frames constitute a high resolution video, all of the video frames constitute a low resolution video to this, a video conference system with H.264 SVC encoded, on the basis of ensuring efficient video compression performance, video broadcasting The end can generate video compression code streams having different frame rates, resolutions by primary coding to accommodate different network bandwidth, different display screens and terminal decoding applications, thereby effectively avoiding the MCU over the video conferencing system.
