APPARATUSES AND METHODS FOR BITSTREAM BITSTUFFING

摘要

Examples of methods and apparatuses for inserting and removing stuffing data in a bitstream described. An encoding system may include an encoder configured to receive a video signal and stuffing data. The encoder may be configured encode the video signal in accordance with an encoding methodology and provide a bitstream based on the encoded video signal and the stuffing data. The stuffing data may include random and/or encrypted data. A decoder may receive a bitstream and remove stuffing data from the bitstream. The decoder may include a padding removal apparatus that may include a slice detection block and a bitstream editor. The slice detection block may be configured to determine locations of stuffing data in a bitstream and provide the locations to the bitstream editor using control signals. The bitstream editor may be configured to remove the stuffing data based on the control signals.
