Digital multimedia play crying. , [Prior Art] Please refer to the figure - Figure 'The existing common number of digits, the function block diagram, which is mainly set up - a file buffer 7 miscellaneous servo H 10 is stored in the multimedia content age, and connected The computer host η on the computer network 1, the computer host 12, etc. can all download the multimedia shouting file from the marrow 1G, and then the computer host 12 uses its own hardware resources to play. △ In another aspect, the digital television network utilizes the function block as shown in the second figure for the purpose of digital content transmission, and the 1st-floor service device 2. The second floor of the store will also store the files of the Neigu. The TV set or the digital TV set 22 with an organic box can be used to capture the slot machine through the TV network 2. The digital multimedia content, or through the function of Video On D嶋nd, is then used by the active (4) server 20 to read a specific digital multimedia content through the television network 2 for playback. The above technical idea is to use the file server to provide digital multimedia content playback on the road connected to the network 1258305 - + but the above-mentioned television to complete the digital multimedia coffee capture and playback of the organic box It may not be appropriate to use a computer host or a 嗖 application in other areas. For example, in the small and medium-sized public places such as the conference venue, the D people want to display the multimedia content playback system at the airport or the digital display. The display screens of the different lounges of the screen can only display the waiting room, but the cost is too high. The computer host or the set-top box can make all the messages. The cost is too high. (4) How to improve the above-mentioned syllabic section: the realization of the development The main purpose of this case is the spindle-capable playback device, which is the content of the invention. The main purpose of the invention is to use the DVD decoder chip which is generally easy to obtain. A network video system. Although the MPEG-2 image compression technology is used inside the DVD, the DVD chip production price is much lower than the existing MpEG_2 decoding system due to the large output of the DVD chip (the wafer price is about 50_70% lower). Since the DVD chip design needs to be used with a DVD player, the present invention specifically designs an interface for converting network data into analog DVD data, so that the inexpensive DVD technology 1258305 can be used for a network-connected video system. SUMMARY OF THE INVENTION This case is a digital multimedia player, which is applied to two benefits: a network interface circuit, the signal is connected to the network, and the data is a large amount of === material 'the digital multimedia storage device data The sink 2 poor material format exists, · a large amount of storage device analog interface circuit, the electrical connection media _ data is read from the network interface circuit, and the re-equipment circuit is transferred to the mass storage device to receive the fresh digital multimedia _ Data decoder, electrically connected to the data storage device of the warehousing storage device, the number of 传送 二 ' 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 According to the above concept, Yang said that the multimedia network is - Ethernet or wireless: S1 Ethernet interface or wireless network interface circuit According to the above concept, the digital space data system described in the present case can be a part of multi-functional audio and video: disc:: According to the above concept, the digital multimedia player described in the present case, wherein 1258305 video sound The data is stored in the standard feed server % after being processed by, for example, an MPEG-2 encoder. The file server 30 can be regarded as an analog multi-function video light (DVD disk), which can be regarded as a part of the digital multimedia compressed data stored in the server 3 Multi-functional audio and video discs (partial DVD data). On the other hand, a plurality of digital multimedia players 31 can be provided to complete the subtraction with Age 3. Each of the health (four) body broadcasts 31 can independently read a part of the multi-function video (four) (partial DVD data) from the file server 30 for loading and unloading. Give a ^ 'This system is built in the airport, we only need to establish an Ethernet network or wireless network (ie network 3) and a computer file server 3〇, and 哕 = brain file servo H In the 30, there are a number of partial multi-function video discs = partial DVD data, which makes the computer file server 3 on the network look like a large capacity with a directory and can be read data. Functional audio and video discs. In this way, the digital multimedia players 31 respectively built in the non-shutdown room can independently read the partial multimedia video data (partial DVD data) required for the purpose of the partial broadcast. and. The smashing of the video data (partial data) means that the file server 30 does not need to wait for a complete DVD poor material to start transmitting images. The file server 3 only needs to generate a few seconds of data to start transferring to our media player. In the transmission of the wealth, you can generate the next few seconds of data, and after the first few seconds of playback, continue to send out... and so on. In this way, the file server % can immediately convert the information from the data port, such as the TV or the camera signal, into the DVD format (partial DVD data), and immediately transmit the broadcast during the transmission. , and then create the next partial data. With this design, the system can be used to quickly achieve timely image transmission applications. Referring to the fourth figure, a block diagram of the internal function of the coefficient bit multimedia player 31 mainly includes a network interface circuit 401 for connecting signals to the network 3, and the inside of the digital multimedia player 31. Mainly utilize a large number of storage device data bus 405 (commonly a CD player/hard disk machine bus, such as ATAPI/IDE BUS) for connection between modules and signals, and a large number of storage device data bus 405 There is a large number of storage device analog interface circuits 4〇4 (when a large number of storage devices are connected to the bus bar 405, a large number of storage device analog interface circuits 4〇4 is an optical disk drive/hard disk drive analog interface circuit) and a compact disc Read 窎罗晋=etc. A large number of storage devices. The control circuit is electrically connected between the network 'I-side circuit 4〇1 and the mass storage device analog interface circuit 4(10), and the circuit 4〇2 is through the network interface circuit and the network 3 Come to the server 3. The multi-digit digital multimedia bus in the middle is transferred to the mass storage device and decoded by the media compression data decoder of the digital multimedia compressed data decoder bar;; = broadcast. As for the digital multi-streaming interface (often _ there are a large number of storage device data sinks for the first disk drive/hard disk machine bus interface, such as 12 1258305 limited 1 material space to play unlimited length of video and audio signals. As you can see, In this case, the digital multimedia playback of the general DVD light 磾趟 姑 十 10 & T spear J used in the base to modify, we only need to add the fourth map and 4 〇 1, control circuit 402, cache memory 403 Read and write 407 sub-interface interface circuit 4〇4, you can even put the disc: t Lr compared to the computer in the dragon means and the machine on the second due to the secret of the DVD handle machine, the dream of this case This can be greatly reduced, 'the system complexity is also greatly simplified, so it can be π into a low-cost but fully functional digital multimedia content playback device, (10) 10%, the main purpose of the exhibition case. And wireless network except 1εεε 8〇2.llb In addition, there are mainly IEEE8〇2Ua and job 8〇2 call specifications, etc. 'This bandwidth is sufficient. However, the invention of this case can be used by those who are familiar with this skill to make all kinds of repairs. Attached to the scope of the patent [Simple description of the diagram] This case can be obtained through a more detailed understanding of the following diagrams and detailed descriptions: Figure-Figures is a functional block diagram of the existing common digital multimedia content dissemination.
