Abstract
본 발명은 영상압축된 디지탈 신호를 편집할 때 복호화기의 입력버퍼상태 제어에 관한 것으로, 일반적으로 사용되고 있는 영상편집방법은 프로그램을 제작하는데 있어서 영상압축된 비트 스트림을 임의의 위치에서 자른 뒤 다른 프로그램을 계속하여 편집하는 경우 각 픽쳐들의 관계가 흐트러져 편집된 영상이 제대로 복원되지 못하게 된다.The present invention relates to the control of the input buffer state of a decoder when editing a video compressed digital signal. In general, a video editing method is used to cut a video compressed bit stream at an arbitrary position and then create another program. When editing is continued, the relationship between each picture is disturbed and the edited image cannot be restored properly.
그리고, 영상압축된 다수의 프로그램들을 편집할 경우에는 복호화기의 버퍼상태를 고려하지 않게 되므로 복호화기의 버퍼가 오버플로우 또는 언더플로우되는 문제점이 있게 된다.When editing a plurality of compressed video programs, the decoder's buffer state is not taken into account, which causes the decoder's buffer to overflow or underflow.
이에 따라, 본 발명의 목적은 상기와 같은 종래의 압축영상 편집방법에 따르는 문제점을 해결하기 위하여, 압축된 디지탈 오디오 및 비데오 신호들을 받아서 사용자의 요구대로 내용을 편집하는데 있어서, 수신단에서의 버퍼상태에 영향을 끼치지 않고 신호를 편집할 수 있도록 하는 디지탈 영상압축신호의 편집장치를 제공하는데 있다.Accordingly, an object of the present invention is to receive the compressed digital audio and video signals and to edit the contents as required by the user in order to solve the problems according to the conventional compressed image editing method as described above. An object of the present invention is to provide an apparatus for editing a digital video compressed signal that can edit a signal without affecting it.
