CN101742071B - Method for recording various formats of video by optical disk type video record-replay set top box - Google Patents

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

Optical disk type video recording/reproducing set-top box is recorded the method for multiple format video

Technical field

The present invention relates to set-top box technique, relate to the method that a kind of optical disk type video recording/reproducing set-top box is recorded multiple format video specifically.

Background technology

Along with the high speed development of Digital Television industry, people can not content just to use set-top box received television program, user to begin to favor set-top box in more high-end; Wherein, the set-top box that has a section directory playing function begins to be subjected to increasing concern.

Advantages such as laser disc, particularly DVD laser disc are cheap because of it, capacity is big have become one of most popular storage medium now, and optical disk type video recording/reproducing set-top box also is a main trend of following set-top box development.Advantages such as adopt DVD laser disc recording TV program to have to use by turns, constantly stored television program, low price, replacing be convenient.

The bit stream that during the video recording/reproducing set-top box of optical disk type video recording at present is the digital television broadcasting program that will receive directly is recorded on the laser disc, middlely changes without digital coding.This mode can easily be carried out recording playback to digital television program, but do not support the image of other non-TS (transport stream) number formats, therefore, the TV programme that present optical disk type video recording/reproducing set-top box is recorded can only use set-top box to watch, can not on other playback terminals, play, cause the unicity of purposes.

Summary of the invention

Technical problem to be solved by this invention is: can only record a kind of deficiency of format video at prior art, propose the method that a kind of optical disk type video recording/reproducing set-top box is recorded multiple format video.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: optical disk type video recording/reproducing set-top box is recorded the method for multiple format video, may further comprise the steps:

A. select the video storage format of needs;

B. if selected the TS form, then TS is flowed the TS data write memory at processing module place, execution in step e is not the TS form as if what select, then execution in step c;

C. the view data with audio frequency and video output module place sends microprocessor to;

D. microprocessor carries out transcoding to the view data that sends, and changes into needed number format image, and is stored to internal memory;

E. start the laser disc recording device data in the internal memory are carved into into laser disc.

Further, video storage format described in the step a is AVI form or MOV form or mpeg format or TS form.

The invention has the beneficial effects as follows: can realize recording of multiple format video, conveniently on multiple playback terminal, play.

Description of drawings

Fig. 1 is a method flow diagram of the present invention.

Embodiment

The invention will be further described below in conjunction with drawings and Examples.

The present invention is directed to prior art and can only record a kind of deficiency of format video, propose the method that a kind of optical disk type video recording/reproducing set-top box is recorded multiple format video, as shown in Figure 1, this method adopts following steps to realize:

A. select the video storage format of needs;

B. if selected the TS form, then TS is flowed the TS data write memory at processing module place, execution in step f is not the TS form as if what select, then execution in step c;

C. the view data with audio frequency and video output module place sends microprocessor to;

D. microprocessor carries out transcoding to the view data that sends, and changes into needed number format image, and is stored to internal memory;

E. start the laser disc recording device data in the internal memory are carved into into laser disc.

Embodiment:

When the user wants TV programme recorded, at first need the image store form of recording (as: AVI (audio frequency and video are staggered) form, MOV (Quick Time film) form, MPEG (dynamic image expert group) form, TS form) is selected, if the user just uses on set-top box, then only need to select the TS form, this moment, set-top box can automatically flow TS in the TS code stream write memory that the processing module place receives, start the laser disc recording device simultaneously laser disc is carried out imprinting, the data in the internal memory are write laser disc.

If the user need watch image on other playback terminals, then to select the corresponding video format of supporting of this equipment, this moment, set-top box can send to microprocessor with the MPEG2 view data at audio frequency and video output module place, by microprocessor the MPEG2 view data is transcoded into user-selected video format again, behind the transcoding in the write memory, start the laser disc fetch equipment simultaneously laser disc is advanced in the data typing in the internal memory, realize that the non-TS form of TV programme is recorded.

Claims (2)

1. optical disk type video recording/reproducing set-top box is recorded the method for multiple format video, it is characterized in that: may further comprise the steps:

A. select the video storage format of needs;

B. if selected the TS form, then TS is flowed the TS data write memory at processing module place, execution in step e is not the TS form as if what select, then execution in step c;

C. the view data with audio frequency and video output module place sends microprocessor to;

D. microprocessor carries out transcoding to the view data that sends, and changes into needed number format image, and is stored to internal memory;

E. start the laser disc recording device data in the internal memory are carved into into laser disc.

2. optical disk type video recording/reproducing set-top box as claimed in claim 1 is recorded the method for multiple format video, it is characterized in that: video storage format described in the step a is AVI form or MOV form or mpeg format or TS form.
