Abstract
A system, method, and apparatus for correcting a corrupted video bitstream using a video bitstream washer. The video bitstream washer of the present invention receives a corrupted video bitstream and produces a syntactically correct video bitstream as an output using correction and concealment of the errors in the video bitstream. The video bitstream washer may be placed in a network for receiving a corrupt video bitstream from an error-prone network and providing a correct video bitstream to an error-free network, providing a correct video bitstream to a video decoder, or as an integrated bitstream washer and video decoder.
Claims32
An apparatus for correcting a video bitstream which has been corrupted by errors, said apparatus comprising:
- a receiver for receiving a corrupt video bitstream, said corrupt video bitstream having at least one error therein;
- and
- a video bitstream washer in communication with said receiver for producing a syntactically correct video bitstream from said corrupt video stream.
An error resilient video decoder for correcting a video bitstream which has been corrupted by errors, said error resilient video decoder comprising:
- a receiver for receiving a corrupt video bitstream, said corrupt video bitstream having at least one error therein;
- a video bitstream washer in communication with said receiver for producing a syntactically correct video bitstream from said corrupt video stream;
- and
- a video decoder in communication with said video bitstream washer for receiving said syntactically correct video bitstream and producing a decoded video image signal therefrom.
A method for modifying a video bitstream which has been corrupted by errors, said method comprising the steps of:
- receiving a corrupt video bitstream, said corrupt video bitstream having at least one error therein;
- if said at least one error is correctable, correcting said at least one error in said corrupt video bitstream;
- and
- if said at least one error is not correctable, concealing said at least one error in said corrupt video bitstream,
- whereby a syntactically correct video bitstream is produced from said corrupt video bitstream.
A system for washing the bits of a video bitstream between a first network and a second network, said first network being substantially error-prone, said second network being substantially error-free, said system comprising:
- an input for receiving a corrupt video bitstream from said first network, said corrupt video bitstream having at least one error therein;
- a video bitstream washer in communication with said input for producing a syntactically correct video bitstream from said corrupt video bitstream;
- and
- an output in communication with said video bitstream washer for providing said syntactically correct video bitstream to said second network.
