Patent ID: 8068721

Claim:
A method of transmitting video data from a first entity to a second entity, whereby the video data comprise information bits, wherein the method comprises the steps of: applying a systematic channel encoding on information bits of video data and obtaining a sequence comprising encoded information bits and error correction bits of the information bits; generating a primary coded picture network abstraction layer comprising the encoded information bits of the video data; inserting the error correction bits into a redundant coded picture network abstraction layer by including error correction data with higher error correction power and with smaller size in the redundant coded picture network abstraction layer, rather than inserting a copy of select encoded information bits from the primary coded picture network abstraction layer; transferring the primary coded picture network abstraction layer and the redundant coded picture network abstraction layer from the first entity to the second entity; receiving the primary coded picture network abstraction layer and the redundant coded picture network abstraction layer at the second entity; using the error correction bits in the redundant coded picture network abstraction layer for detecting and correcting errors in the received primary coded picture network abstraction layer to form a corrected primary coded picture network abstraction layer; and performing video decoding of the corrected primary coded picture network abstraction layer to form corrected information bits corresponding to the information bits of the video data.
