Patent ID: 8654863

Claim:
A method of operating an apparatus for video source decoding, the method comprising: receiving, by the apparatus, at least part of a first source encoded bit-stream portion representative of a first video frame, the first source encoded bit-stream portion comprising picture header data for the first video frame and corresponding source encoded picture data for the whole of the first video frame; determining, by the apparatus, whether a second received source encoded bit-stream portion, provided in the source encoded bit-stream subsequent to and outside the first source encoded bit-stream portion, comprises a repeat of at least a part of the picture header data for the first video frame; and obtaining, by the apparatus, the repeated picture header data for the first video frame from the second received source encoded bit-stream portion for use in decoding source encoded picture data for the first video frame provided in the first source encoded bit-stream portion when it is determined that the corresponding picture header data for the first video frame has been corrupted or lost.
