Abstract: Electronic Guide produces give the user the ability to videotape selected programs. Once a program has successfully been taped a message is displayed, reminding the viewer that they have taped it.

For at least some of the positions of the skimming tool, the picture generator presents a video picture that is not at the location identified by the skimming tool, but rather is at a nearby location and is easier to present in the preview than the video picture at the identified location.

Abstract: The present invention relates to a playback apparatus, a playback method, a program, a recording medium, and a data structure that enable interactive operations when playing back AV content. A controller 34 obtains an order list of audio stream numbers in advance.

It is then checked whether a stream that is found to be playable by the playback apparatus is included in a main clip or a sub clip, and the main clip referred to by the Main Path is read together with the clip in which the corresponding audio stream is multiplexed. Then, the audio stream file of the corresponding clip and the file to be played back included in the main clip are selected by the switches 57 through 59, and 77. The selected files are combined by a video data processor 96 and an audio data processor 97, and the combined data is output.

Abstract: There is disclosed a stream data reception/reproduction device capable of suppressing deterioration of quality of stream data reproduced even when the stream data is received via an IP network or the like in which the packet arrival timing and the order are not guaranteed. In this device, a reproduction speed control unit (107) sets various conditions in accordance with the value of the synchronization difference reported from a synchronization difference calculation unit (102). Only when the set conditions are satisfied, the speed of reproduction of a frame decompressed and inputted from a decoding unit (105) is adjusted. The reproduction speed control unit (107) interpolates a predetermined amount of sample data into the frame or decimates it from the frame when adjusting the reproduction speed.

Offset control is processing to provide a left offset and right offset for the horizontal coordinates in a graphics plane to generate a pair of graphics planes that are respectively combined with main-view and sub-view video planes. The playlist information includes a stream selection table for each playback section. When the stream selection table associates a stream number with a packet identifier of a graphics stream, one of the offset identifiers is further allocated to the stream number.

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.
