Abstract: A digital video recorder stores digital video streams having sequences of encoded frames that are predominantly non-keyframes. The digital video recorder synthesizes keyframes for the digital video stream by decoding the frames in sequence and occasionally capturing the state of the decoder as it decodes the frames. The decoder states are stored in a state index in association with the frames. During playback at normal or accelerated speeds, the digital video recorder is capable of random accelerated access of any frame in the digital video stream. A decoder state associated with the accessed frame is retrieved from the state index and used to begin decoding at or near the accessed frame. The decoder state initializes a playback decoder to the state that enables complete decoding and rendering of the accessed frame without having to decode multiple frames previous to the accessed frame, thereby minimizing time delays in playback.

Abstract: Movies are produced in 24 Hz frame frequency and progressive scanning format (denoted 24p) for projection in film theatres, adhering to a worldwide standard for 35 mm film. However, the major TV systems in the world use interlaced scanning and either 50 Hz field frequency (denoted 50i) or 60 Hz field frequency (denoted 60i). Content providers would prefer providing single-picture-frequency single-audio-speed AV discs that can be replayed in most parts of the world. According to the invention, For a 50 HZ output mode, in the media player either audio signal frames are dropped adaptively or video fields or frames are repeated adaptively, depending on the current video and audio content. Thereby the less perceptible stream controls the synchronization.
