Embodiment 1

[0023] The technical solution provided by the embodiment of the present invention is to meet the requirements for additional recording and power-off protection during real-time recording by using the extended identifier in the FSD on the premise of conforming to the UDF standard.

[0024] figure 1 It is a flow chart of a real-time recording method for a synchronous recording and video recording disc provided by an embodiment of the invention, as shown in figure 1 As shown, the methods described include:

[0025] S101. Record a first file set descriptor FSD in an optical disc, where the first FSD includes a first file capacity and a first start position.

[0026] In the embodiment of the present invention, the optical disc can be a one-time writable optical disc, such as CD-R, DVD+R, DVD-R, etc. After the recorder burns the volume structure of UDF, it burns the first FSD (file set descriptor, file set discriptor), FSD is one of the file set descriptor sequence FSDS (File Set ...

Embodiment 2

[0071] Figure 4 It is a block diagram of a real-time recording device for a synchronous recording and video recording provided by an embodiment of the present invention, as shown in Figure 4 As shown, the device includes: a first FSD recording unit 401, a first recording unit 402, a first capacity judgment unit 403 and a first data division unit 404, wherein:

[0072] The first FSD recording unit 401 is configured to record a first FSD in an optical disc, and the first FSD includes a first file capacity and a first starting position.

[0073] In the embodiment of the present invention, the optical disc can be a one-time writable optical disc, such as CD-R, DVD+R, DVD-R, etc. After the recorder burns the volume structure of UDF, the first FSD recording unit 401 is on the optical disc. Burn the first FSD (file set descriptor, file set discriptor), FSD is one of the file set descriptor sequence FSDS (File Set Descriptor sequence), the sequence information needs to be recorded ...

Abstract

The invention relates to a real-time burning method and device of an optical disk for synchronous audio and video recording. The method comprises the following steps of: burning a first file-set descriptor FSD in the optical disk, wherein the first FSD comprises a first file capacity and a first starting position; receiving real-time data and starting to burn for the first time at the first starting position; judging whether the size of the real-time data burnt for the first time reaches the first file capacity; and if the size of the real-time data burnt for the first time reaches the first file capacity, partitioning the real-time data to finish the first burning. According to the real-time burning method and device of the optical disk for synchronous audio and video recording provided by the invention, real-time burning can be directly performed on an audio and video file under the condition that complete data and size of a burnt file are not acquired, additional burning can also be realized, and normal reading of burnt data can also be guaranteed even though power is turned off during burning.

Description

technical field [0001] The present invention relates to the technical field of optical disc recording, in particular to the technical field of real-time recording of streaming media, in particular to a method and device for real-time recording of an optical disc with synchronous recording and video recording. Background technique [0002] With the continuous development of streaming media technology, how to burn streaming media files to CDs in real time has become an urgent problem to be solved. [0003] For one-time writable discs (CD-R, DVD+R, DVD-R, etc.), the traditional way of burning discs is to package the files to be burned first to generate image files, that is, to convert the files in the hard disk into UDF files. The standard of the system is to generate an image file in UDF (Universal Disk Format) format, record it in the hard disk or memory, and then sequentially read the image file from the hard disk or memory and burn it to the CD. [0004] The traditional re...
