Patent Number: 6,480,539

Title: Video encoding method and apparatus

Abstract: An exemplary video encoder is disclosed that quantizes pel blocks of a video signal based upon one or more of the following: (i) an actual bit distribution of a previously encoded video frame, (ii) a required decoding delay for a splice point, and (iii) an activity measure of a pel block being encoded. Moreover, an exemplary video encoder uses the above quantization techniques to obtain an encoded video stream having seamless in points and seamless out points. Video encoding methods that utilize the above quantization methods are also disclosed.
