Video coding and decoding methods |
摘要 |
Video coding and decoding methods. The video coding method includes: receiving channel status information indicating an error profile of the communication channel; and adaptively adding redundancy information into data packets divided by syntax with a layer configuration, based on the channel status information. The video decoding method includes: receiving an encoded video bitstream; identifying whether an additional layer is present and which layer has been added; and decoding corresponding layers based on the information about the additional layer. The video coding and decoding methods can be implemented in a video coder-decoder (CODEC) to avoid erroneous decoding in an error-prone channel, thus improving error-resilience of the CODEC.
