摘要： In various embodiments, an encoding optimization application positions key frames within encoded video sequences based on shot changes. The encoding optimization application determines key frame location(s) based on shot change(s) included in a source video sequence associated with a media title. Each key frame location is associated with a different frame included in the source video sequence. For each of the key frame location(s), the encoding optimization application configures an encoding application to encode a frame of video content located at the key frame location as a key frame when performing encoding operations. Subsequently, the encoding optimization application causes the encoding application to perform encoding operation(s) on the source video sequence to generate a first encoded video sequence. During playback, the media title is switchable between a decoded version of the first encoded video sequence and a decoded version of a second encoded video sequence at the key frame location(s).

摘要： In a recording medium on which is recorded a multiplexed stream including a plurality of first packets (V_main) constituting a first I-picture in a first video stream and a plurality of second packets (V_sub) constituting a second I-picture in a second video stream, information for identifying the first I-picture and information for identifying the second I-picture are recorded on the medium. A recording medium can thereby be obtained that enables the rapid detection, from a small amount of information, of a particular picture included in a stream such as a TS in which multiple content streams are multiplexed.

摘要： A system and method disposed to enable encoding, decoding and manipulation of digital video with substantially less processing load than would otherwise required. In particular, one disclosed method is directed to generating a compressed video data structure that is selectively decodable to a plurality of resolutions including the full resolution of the uncompressed stream. The desired number of data components and the content of the data components that make up the compressed video data, which determine the available video resolutions, are variable based upon the processing carried out and the resources available to decode and process the data components. During decoding, efficiency is substantially improved because only the data components necessary to generate a desired resolution are decoded. In variations, both temporal and spatial decoding are utilized to reduce frame rates, and hence, further reduce processor load. The system and method are particularly useful for real-time video editing applications.

摘要： A digital decoder for television receiver, comprises an input (E) for receiving a digital audio/video signal (SAV), means for demodulating and decoding the input signal into an output signal intended for the television receiver, and a first buffer memory (8) into which the input signal is diverted after demodulation (SD) when the decoder is placed in a so-called “live” mode of operation. In a so-called “playback” mode of operation, the signal recorded in the first buffer memory constitutes the output signal. This decoder comprises a second buffer memory (9) into which the demodulated input signal (SD) is diverted when the decoder is placed in the “playback” mode, the signal recorded in the second buffer memory (9) constituting the output signal when the decoder is switched from the “playback” mode to another so-called “return to live” mode of operation. In the “return to live” mode, the user views at high speed the video portion recorded in the second buffer memory before the decoder switches back to the “live” mode.

摘要： A digital video recorder and a video recording and playback method thereof are provided. The digital video recorder includes a first decoding module, a second decoding module, and a video processing module. The first and the second decoding modules decode a video signal into a first image signal and a second image signal. A first command signal is produced when the first image signal is correct, and a second command is produced when the second image signal is correct. The video processing module selectively outputs the first image signal or the second image signal according to the first and the second command.
