Abstract
A method of adding comfort noise to a video sequence comprising setting parameters of a deblocking filter of a video encoder to change values during the video sequence, encoding frames of the video sequence using the parameters of the deblocking filter that are set to change values during the video sequence, thereby introducing comfort noise in the video sequence, and including the encoded frames in a bitstream together with an indication of which parameters of the deblocking filter were used when encoding the frames of the video sequence.
Claims15
A method of adding comfort noise to a video sequence, comprising:
- setting parameters of a deblocking filter of a video encoder to change values during the video sequence,
- encoding frames of the video sequence using the parameters of the deblocking filter that are set to change values during the video sequence, thereby introducing comfort noise in the video sequence, and
- including the encoded frames in a bitstream together with an indication of which parameters of the deblocking filter were used when encoding the frames of the video sequence.
A controller for controlling a video encoder to add comfort noise to a video sequence, comprising:
- a parameter setting component configured to set parameters of a deblocking filter of a video encoder to change values during the video sequence, and
- a control component configured to instruct the video encoder to encode frames of the video sequence using the parameters of the deblocking filter that change values during the video sequence, thereby introducing comfort noise in the video sequence, and include the encoded frames in a bit stream together with an indication of which parameters of the deblocking filter were used when encoding the frames of the video sequence.
A computer program product comprising a computer-readable medium having computer code instructions stored thereon adapted to carry out the method, when executed by a device having processing capability, comprising:
- setting parameters of a deblocking filter of a video encoder to change values during the video sequence,
- encoding frames of the video sequence using the parameters of the deblocking filter that are set to change values during the video sequence, thereby introducing comfort noise in the video sequence, and
- including the encoded frames in a bitstream together with an indication of which parameters of the deblocking filter were used when encoding the frames of the video sequence.
