Adaptive decoding of a video frame in accordance with initiation of non-sequential playback of video data associated therewith

A data processing device comprising:

• a memory;
• and
• a processor communicatively coupled to the memory, the processor being configured to execute instructions to:
• determine that a reference video frame of one of:
• a predicted frame and a bi-predicted frame, corresponding to a point in time of beginning of a non-sequential playback of video data including an encoded form of the one of:
• the predicted frame and the bi-predicted frame and currently being decoded, is one of:
• unavailable and corrupt,
• determine if a reference video frame utilized most recently with reference to the point in time to decode another video frame of the video data is available in the memory following the determination of the one of:
• the unavailability and the corruptness of the reference video frame of the one of:
• the predicted frame and the bi-predicted frame,
• decode the one of:
• the predicted frame and the bi-predicted frame based on employing the reference video frame utilized most recently as a reference video frame of the one of:
• the predicted frame and the bi-predicted frame if the reference video frame utilized most recently is determined to be available in the memory, and
• decode the one of:
• the predicted frame and the bi-predicted frame based on employing a video frame of the video data in the memory temporally closest to the point in time as the reference video frame of the one of:
• the predicted frame and the bi-predicted frame if the reference video frame utilized most recently is determined to be unavailable in the memory.

A system comprising:

• a source data processing device configured to encode video data including data associated with one of:
• a predicted frame and a bi-predicted frame as a video sequence, the one of:
• the predicted frame and the bi-predicted frame corresponding to a point in time of beginning of a non-sequential playback of the video data;
• and
• a decoder communicatively coupled to the source data processing device, the decoder being at least one of a hardware decoder and a decoder engine executing on a processor communicatively coupled to a memory, and the decoder being configured to:
• determine that a reference video frame of the one of:
• the predicted frame and the bi-predicted frame, when currently being decoded, is one of:
• unavailable and corrupt,
• determine if a reference video frame utilized most recently with reference to the point in time to decode another video frame of the video data is available in the memory following the determination of the one of:
• the unavailability and the corruptness of the reference video frame of the one of:
• the predicted frame and the bi-predicted frame,
• decode the one of:
• the predicted frame and the bi-predicted frame based on employing the reference video frame utilized most recently as a reference video frame of the one of:
• the predicted frame and the bi-predicted frame if the reference video frame utilized most recently is determined to be available in the memory, and
• decode the one of:
• the predicted frame and the bi-predicted frame based on employing a video frame of the video data in the memory temporally closest to the point in time as the reference video frame of the one of:
• the predicted frame and the bi-predicted frame if the reference video frame utilized most recently is determined to be unavailable in the memory.
