Embodiment 1

[0053] The system structure of this embodiment sees figure 2 , including: a file format conversion unit 21, an operating system 22, an operating system interface unit 23, a hardware interface unit 24 and multimedia hardware 25.

[0054] Wherein, the file format conversion unit 21 is further divided into a format comparison module 211 and a format conversion module 212 .

[0055] The format comparison module 211 pre-stores format information of various existing multimedia data. The existing multimedia data may be some mainstream media formats, such as MP3, Wave, Midi, etc., or any interesting media format. Format information includes data header, compression, etc., where the data header carries additional information such as recording author and copyright.

[0056] The format conversion module 212 is used to convert various media formats stored in the format comparison module 211 into a unified common format. The public format is a pre-defined, highly extensible standard data...

Embodiment 2

[0079] exist figure 2 In the system structure shown, since the external multimedia data is converted into a common format, it is directly sent to the operating system for subsequent processing, so it is not necessary to compress the data in the common format.

[0080] In order to ensure the integrity of the multimedia playback system, the system can also save the converted public format data as a file, that is, the format conversion unit 212 saves the multimedia data to the storage unit after converting the format of the multimedia data. Since multimedia data generally has a large amount of data, it needs to be compressed and saved. In order to meet the above requirements, a compression / decompression module 413 is further set in the file format conversion unit 21, and the specific structure is shown in Figure 4 .

[0081] The format conversion module 212 sends the multimedia data in the common format to the compression / decompression module 413 , which compresses the multime...

Abstract

The invention discloses a total-phase-type multimedia integrated play system and method, which comprises the following parts: operation system, multimedia hardware, file pattern switching unit, operation system interface unit and hardware interface unit, wherein the file pattern switching unit transforms the received external multimedia data into the public pattern multimedia data and sends to the operation system; the operation system receives the public pattern multimedia data and transforms the public pattern multimedia data into public activation signal then sends to the hardware interface unit; the hardware interface unit sends the signal to the multimedia hardware to play.

Description

technical field [0001] The invention relates to the field of multimedia applications, in particular to a universal multimedia integrated playing system and method. Background technique [0002] With the development of society and economy, the status of multimedia technology in the IT industry is becoming more and more important, and there are more and more hardware, software and service manufacturers developing multimedia. The independent technology development of these manufacturers has led to the diversification of formats and standards in the multimedia field, so that specific hardware or playback software can only support specific data formats, and specific operating systems can only support specific playback software. [0003] As shown in Figure 1 in the existing multimedia playing system, the playing software sends the multimedia data to the operating system, and the operating system drives the multimedia hardware to play the multimedia data. In the above process, sin...
