Embodiment

[0023] When a user wants to record a TV program, he first needs to store the recorded image in the format (such as: AVI (Audio and Video Interleaved) format, MOV (Quick Time Movie) format, MPEG (Motion Picture Experts Group) format, TS format) Make a selection, if the user is only using it on the set-top box, then only need to select the TS format, at this time the set-top box will automatically write the TS stream received by the TS stream processing module into the memory, and at the same time start the CD burning device to burn the CD. Write data in internal memory to disc.

[0024] If the user needs to watch images on other playback terminals, he must select the corresponding video format supported by the device. At this time, the set-top box will send the MPEG2 image data at the audio and video output module to the microprocessor, and then the microprocessor will send the MPEG2 image data to the microprocessor. The data is transcoded into the video format selected by the ...

Abstract

The invention relates to the technology of a set top box, in particular to a method for recording various formats of video by an optical disk type video record-replay set top box. Aiming at the defect that only one format of video can be recorded in the prior art, the invention discloses a method for recording various formats of video by the optical disk type video record-replay set top box. The key points of the technical scheme is as follows: a. selecting a required video storage format; b. if a TS format is selected, writing TS data in a TS stream processing module in a memory, and executing step f, and if the selected format is not the TS format, executing step c; c. transmitting image data in an audio and video output module to a microprocessor; d. transcoding the transmitted image data into required digital format images by the microprocessor, and saving the images in the memory; and e. starting an optical disk burning device to burn the data in the memory into an optical disk. The invention has the beneficial effects of realizing recording of various formats of video and being convenient for playing on various play terminals.

Description

technical field [0001] The invention relates to the technology of a set-top box, in particular to a method for recording multiple formats of video in a CD-type video recording and playback set-top box. Background technique [0002] With the rapid development of the digital TV industry, people are no longer satisfied with using set-top boxes to receive TV programs, and users are beginning to favor higher-end set-top boxes; among them, set-top boxes with program playback functions have begun to receive more and more attention. [0003] Optical discs, especially DVD discs, have become one of the most popular storage media due to their low price and large capacity. The optical disc-type video recording and playback set-top box is also a major trend in the development of set-top boxes in the future. The use of DVD discs to record TV programs has the advantages of being able to be used in rotation, continuously storing TV programs, cheap, and easy to replace. [0004] At present,...
