Abstract
Video data is received at a decoding device. An encoded first frame of the video data is received with a current frame description for the first frame comprising: an identifier of the first frame, and an indicator of a storage location at the receiving device for the first frame and its frame identifier. An encoded second frame of the video data is also received with at least one reference frame description for the second frame comprising: a reference frame identifier, and an indicator of said storage location. This allows the decoding device to check that the correct reference frame for decoding the second frame is stored thereat. Corresponding encoding operations are also disclosed.
