More Information
Summary:The invention relates to the field of compression and transmission of digital video signals and discloses an error concealment method based on the state of a signal channel and visual perception side information, and the error concealment method comprises the steps of mainly utilizing the current state of the signal channel and a visual perception weight map which is transmitted in the side information form, calculating the reliability weights and the reconstruction weights of adjacent macro-blocks, carrying out error concealment treatment on error video images with different code types on space domain and time domain respectively and improving the video decoded image quality under the error-prone transmission condition.
