Description

Sound/video file processing method, playback control method and playback system

technical field

The invention relates to a file processing system, in particular to a sound/video file processing and playing system.

Background technique

The most common shortcoming of the common music/audio players in the market is that they cannot select the segment to be played by themselves when playing files. In the case of old-style cassettes, only by trial and error (Trial and Error) can the tape be fast forwarded or reversed to select the audio track to be played. Taking CD as an example, it can only be selected by selecting the track one by one. If you want to select a picture of a certain time in a certain music or audio-visual file, it is still the same as the old-style cassette, and you can only select it through trial and error. In this way, the tape can be fast forwarded or reversed continuously to select the part to be played. For the most popular MP3 format at present, the section to be played can be selected by pulling the audio track BAR. Although the process of trial and error can be shortened, it is impossible to accurately select the section to be played at one time.

In other words, when wanting to listen to the data of a certain section repeatedly, the user must spend a lot of time operating the player to hear the section he needs. This is very inconvenient for users who use such players for language learning or audio tours.

Digital music/video files can be divided into several music/video files according to the designer's ideas through software. In this way, although the user can select the desired music/audio file to play, the designer must spend a lot of time on file segmentation and naming; If the file is expected to be played continuously, it may also cause the user to feel intermittent because it contains several files.

For example, as shown in FIG. 1B, the audio/video data part is divided into 6 blocks, and each block is given a code (for example, block 1, block 2, etc.). Then, according to user requirements or file size, in step 208, the first-level blocks are further divided into multiple second-level blocks. In step 210, mark the layer 2 blocks as a plurality of layer 2 addresses. And in step 212, a second code is assigned to each second layer address respectively. For example, as shown in Figure 1C, the first layer block 1 is divided into 6 second layer blocks, and each second layer block is given a second code (for example, block 1.1, block 1.2, area block 2.1 etc.). In step 214, the first codes and the second codes are combined into an index (Index) to indicate a zone (Zone) of the audio/video file. Among them, the index data will be stored in the tag of the audio/video file.

In another embodiment, if the size of the audio/video file is too large or the user needs finer segmentation, each second-level block can be divided into multiple sub-blocks, and the sub-blocks can be marked as multiple sub-blocks. The third-level address, and each of the third-level addresses is assigned a third code, and finally the third code is combined with the first code and the second code as an index to point to a specific time of the audio/video file. interval or time series.

For the convenience of understanding, an implementation manner in which numbers are used as codes is listed here. In an embodiment where the index is used as a section, the audio/video data is divided into three layers of blocks, and each block is a section with a time length of 10 seconds. Therefore, when dividing the audio/video data, each block is composed of three codes, for example, 1.1.1, 1.1.2, which are combined into an index. Assume that the code 1.1.1 points to the interval of the block from 0:11 to 0:20. Then the block of code 1.1.2 points to the interval of 10 seconds played from 0 minute 20 seconds, and so on, the audio/video file is divided into multiple intervals. In an embodiment of the present invention, the first code, the second code, and the third code may include one or more bits, but not limited thereto.
