ABSTRACT:
An encoder to encode video streams representing a moving picture is provided whose video encoder calculates a bit storage quantity an STD video buffer should have when input of a stream ending with a first picture to the STD video buffer ends, calculates an initial bit storage quantity of a second picture of a stream concatenated to the end of the first picture and starting with the second picture, in a VBV buffer, based on the calculated bit storage quantity of the STD buffer, and encodes the stream based on the bit storage quantity. The video encoder further calculates a bit storage quantity of the STD video buffer, for decoding a picture of the stream in the STD video buffer, calculates, based on the calculated bit storage quantity, a bit storage quantity the VBV buffer should have for ending decoding of a fourth picture of a second stream concatenated to the beginning of a third picture and ending with the fourth picture, and encodes the stream based on the calculated bit storage quantity. With such encoding, a part of video streams can be re-coded without referencing to information indicative of an initial status of a video buffer when editing the video streams.
