| 摘要 |
The invention concerns a method of transmitting video data comprising information bits (201), a video processing unit (10, 20, 40) with a control unit (12, 22, 42) for sending and/or receiving such video data, and a computer program product for the execution of said method. The method comprises the application of a systematic channel encoding (202) on the information bits (201) of the video data and obtaining a sequence comprising the encoded information bits (203) and error correction bits (204, 403) of the information bits (201). For transmission to another video processing unit (10, 20, 40), the encoded information bits (203) and the error correction bits (204, 403) are inserted into a primary coded picture network abstraction layer (205, 401) and a redundant coded picture network abstraction layer (206, 402), respectively. At the other video processing unit (10, 20, 40), the error correction bits (204, 403) in the redundant coded picture network abstraction layer (206, 402) are used for detecting (404) and correcting (405) errors in the received primary coded picture network abstraction layer (205, 401) and for performing the video decoding (407) of the corrected primary coded picture network abstraction layer (406).
