To record video and audio information on video discs and diverse digital discs, it is necessary to compress the digital video and audio breeding materials using complex moving-day expert group technology in order to store the huge amount of video and audio information in a limited recording medium. Results , The required coding method and the circuit design of the encoder become complicated. In particular, in order to reproduce the original in real time Compressed video and audio data stored on video discs and digital versatile discs must use a specially designed decoder and a dedicated audio and video reproduction device. For example, a digital versatile disc must be used. Can only be played by a DVD player, and cannot be used to enrich the audio and video information recorded on it by a digital music player (CD-DA Player). As is known to all, the price and manufacturing cost of diversified digital players are much higher than digital music players This price and cost difference obviously comes from the complicated decoding methods and decoders used by the various digital I optical disc systems. [New Content] The complexity and high cost of today's audiovisual information equipment hinder the dissemination of audiovisual information and Utilization.

M257575 [Embodiment] The following description and drawings will make the foregoing and other objects, features, and advantages of the present invention more apparent. A preferred embodiment according to the present invention will be described in detail with reference to the drawings. Fig. 1 shows a flow chart of a method for encoding audiovisual information according to the new type. Referring to FIG. 1, digital audio information 10 is prepared in step ES1, and digital video information 20 is prepared in step ES2. The steps ESI and ES2 must be the same. In step ES1, the digital audio information J 0 is generated by performing audio signal processing ESI on the audio source (Audio Source) 101. The audio source 101 may include an analog source and / or a digital source. For example, audio signal processing ES 丨 can be Sampling, Subsampling, and Tuning related to sound quality, etc., which are all techniques familiar to those skilled in this technology, so I won't go into details here. The audio signal processing ES 1 ′ may also include the conventional audio compression technology, so that the digital audio information 10 is a lean signal generated by compression. In one embodiment of the present invention, the audio source 10 can be a dual-channel 16-bit wave format (Wave Format) data, and is converted into a mono 8-bit wave by audio signal processing ESI 'resampling. Format information. In the case where the digital audio information 10 can be directly obtained, for example, the audio source is a mono 8-bit wave format data, there is no need to perform any additional audio signal processing ESI ′. In step ES2, the digital video information 20 is generated by performing video signal processing on the video source 201 (Video Source 201). The video source 20 1 may include analog sources and / or digital sources. For example, s ’video news 5 tiger processing E S 2 server is sampling, resampling, and the negative adjustment of the related video products’ are all techniques that are familiar to those skilled in this technology, so I wo n’t repeat them here. The video signal processing ES2 may also include the conventional video compression technology, which makes the digital video information 20 compressed information. In one embodiment of the present invention, the video source 201 can be a 24-bit bitmap format data, and after the video signal processing ES2 'resampling is converted into 4-bit bitmap format data . In the case where digital video information 20 can be obtained directly, for example, the video source 2 01 is a 4-bit bitmap format, there is no need to perform any additional video signal processing ES2 ,. In step ES3, at least one sync field is set in the digital audio information 10 and the synchronization data is filled in to generate audio information 30 containing a Synchronization-Audio Packet (SAP). Fig. 2 (a) shows a schematic diagram of the format of a synchronous audio packet sap according to the present invention. Referring to FIG. 2 (a), the synchronous audio packet sap is composed of a synchronous field and an audio block. The sync field is used to store sync data, and the audio block is used to store audio information. In one embodiment, the synchronization block can accommodate nine bits of synchronization data, and the audio block can accommodate one byte of audio information. In one embodiment, the synchronization data includes data of nine bit groups consisting of nine binary codes E1, 81, C7, E1, 81, C7, E1, 81, and C7. Each byte has 8 bits. In this embodiment, the synchronization data is actually formed by repeating the three codes E1, 81, and C7 three times, the purpose of which is to reduce the probability of detecting an error. The nine 11 M257575 = groups of synchronization data and one byte of audio information A together form a group of synchronized audio packets SAp. Please note that in the 5v daily frequency packet SAP according to the new model, the synchronization data is not limited to the nine bytes consisting of ei, 8i, c7, a C7 E1, 81, and C7. And / or other numbers of bytes. When the synchronization shelf = the storage space provided is large ^ the amount of synchronization data to be stored, the excess space beyond the synchronization block must be filled with non-substantial dummy data (d_y data). In addition, the synchronous audio packet SAP according to the new model is not limited to Bai Dong—plus #-/ —, ^ 3 bits of audio information, but also: 3: audio information of one or more bits, According to the number of stored frequency: number of messages and the data capacity (or bandwidth) of the recording medium used, in one embodiment of the present invention, the synchronized data can be used to provide audio and video signals for playback. It can be used with the synchronization signal required for reproduction and can be used as a frame marker. In step ES4, at least-control block and fill in the control data is set in the digital audio information 30 containing the synchronous audio packet sAp to generate the synchronous audio packet SAP and the control audio packet (c〇ntr〇i_Audi). Packet, CAP) audio information 40. Fig. 2 (b) shows a schematic diagram of a format of a control audio packet CAP according to the present invention. Referring to FIG. 2 (b), the control audio packet CAP is composed of a control field and an audio field. Control blocks are used to store control data, while audio blocks are used to store audio information. In one embodiment, the control u field can hold nine bytes of control data, and the audio block can hold one bit of audio information. In the embodiment, the control data includes data of nine bytes, as shown in the figure by reference 12 · M257575 No. 2 Cl to C9. The nine bytes of control data c to C9 together with the one-byte audio information A form a twelve C; to control the audio packet CAP. Noisy, active, or stand-alone $, and the CAp φ ^, the main idea in the control of audio packets according to the new model, the control of the poor material is not limited to the implementation of the nine bytes. When the storage space provided by the control shelving :: = = = ㈣㈣, the super control of the control shelving = = dummy data of inconsistent meaning is filled. In one of the new models, the control field is completely "real V" meaning =: Whoever fills in according to the new model's control.
