Abstract: |
The method defines a dedicated cut ID code in video encoding and decoding rules. If encoded code stream to be cut, cut ID code is added to the code stream. Or, original ID codes of playing role of originating marker are replaced by cut ID codes. The invention provides convenience for operation of cutting video code stream. Characters of the invention are that in not cut code stream, it is not needed of appearing bit to indicate whether there is error decoding display possible occurred in video code stream being cut. If code stream is cut at a place, an ID code is setup there in order to indicate image occurred is not to be normal decoded possibly caused by prediction reference data being cut out. |
