transmitting video and audio data, and more particularly to a method for broadcasting and subscribing to audio and video data. [Prior technology], as the industry! Knowing that compared to analog signals, digital signals are easier to process, process, transmit, debug, and store. Therefore, due to the aforementioned advantages, digital TV technology will soon replace the original ones. Analog TV technology, and become a new generation of TV systems 0 Now, some Internet operators have launched digital TV services. For example, Chunghwa Telecom has launched MOD services, which allows users to h select the way to instantly watch digital TV channels, movies, or a variety of audio and video content; users only need to install a digital TV set box (set top bGX), which can be provided through the set-top box The user "face' selects the channel or video that he wants to watch; in a word, the user communicates with the health (4) through the set-top box, so that the program to be watched can be downloaded from the server side. In other cases, the 'mechanical box is transmitted by the network route and the server end. However, the mechanism of the attack has a disadvantage; as mentioned above, the user's view is transmitted from the server. The instant video, however, System 2 must provide a large data transmission bandwidth to support the aforementioned instant image function. Obviously, such an approach is not economical. 200845755 In addition, with the evolution of technology, the image quality is getting higher and higher, which means that the network must provide more bandwidth, in order to transmit the higher resolution of the image to the set-top box. Therefore, if the bandwidth is limited, it may not be possible to transmit images of high image quality in real time, which imposes restrictions on the image products. [Invention] Therefore, one of the main purposes of the present invention is to provide a video and audio material 2 broadcasting method and a related video and audio data dissemination system, which can transmit audio and video data to the set-top box in advance according to the user's long X broadcast mode. In order to save 2, the user will not have the limitation of data bandwidth when viewing the audio and video materials, thereby solving the problem of the prior art. According to an embodiment of the present invention, a method for propagating audio and video data is disclosed, which includes: broadcasting in a plurality of channels (br〇adca): providing a program I, the program table includes According to the program list, one of the plurality of video and audio valleys is selected, and one of the plurality of video channels corresponds to one of the audio and video content ants/downloading the contents of the video; and providing one The storage device is configured to store the downloaded 亥 曰 曰 曰 谷 = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Channel ("h-type transmission-audio-video content; and - set top box), which includes a storage device that is stored in the #in & storage device, the box is used to receive a frame" and according to the The instruction downloads the video content from the channel, and stores the shadow 200845755 in the storage device. The & month downloads the user's required resources in advance by means of pre-downloading, Body ^ for 5 The user does not watch the audio-visual materials in an instant manner, but does not view the audio-visual materials asynchronously. Therefore, the bandwidth requirement is relatively loose for the overall system, and the shirts of Li Wei are allowed to be drawn. In addition, the present invention integrates technologies in two different fields of broadcasting, networking, and electronic communication to provide users with a brand new viewing mechanism to allow users to select audio and video materials to be downloaded anytime and anywhere. The electronic device such as a mobile phone can watch the program anytime and anywhere. [Embodiment] Please refer to FIG. 1 , which is a functional block diagram of the first embodiment of the video and audio data transmission system 100 of the present invention. The video data transmission system 100 includes a server 11A, a set-top box 12A, and a playback device 130. The server 110 is a plurality of audio and video broadcasts by a plurality of channels. The content (vide〇c〇ntem) is transmitted; here, please note that the above-mentioned video and audio content (the video in the valley 1 to the top of the valley 4) can be various. Various digital audio and video materials, such as electric programs or television programs, are used by the server 11 to broadcast these digital audio and video materials through different channels (CH1 to CH4 shown in Fig. 1). Note that the present invention does not limit the specification of digital broadcasting. For example, the server 110 can transmit video and audio data using digital broadcasting under the DVB-T/H specification definition. $ 200845755 120 includes at least one day 120 can utilize the antenna and another In this embodiment, the set-top box line 121 and the storage device 122; therefore, the set-top box m' downloads the aforementioned video and audio content w from each corresponding channel (cm~ch4) and downloads it. The audio and video content is stored in the storage device. Thus, the H user wants to play the audio and video contents, and the set-top box 120 can read the downloaded audio and video content from the storage device 122 and transmit it to the playback device 13G for presentation to the user 0. In this embodiment, in order to prevent the set-top box 12 () from being able to download the required video in one time, the S's feeder 11G plays the video and audio content repeatedly in the aforementioned channels, so that it is so cool that she is on the wooden machine. The box 120 can download a portion of the audio and video content in portions and download the required video and audio content completely via at least one or more downloads. As can be seen from the description, the right user can pre-select the video and audio valley to be viewed, and then use the set-top box 120 to download the required video and audio content from the corresponding frequency C; 卩 ' 'When the download is over, the user will You can watch the programs you want. Please note here that in the present embodiment, the present invention further has a subscription mechanism. To assist the user in selecting the desired audio and video content. As shown in the figure, the server 110 broadcasts a program list in addition to the different audio and video contents on the respective channels (CH1 to CH4) and on a specific channel (CH5). In the eighth, the program schedule carries relevant information of various audio and video content, and 2, the user selects the basis of the audio and video content; for example, the program list can be a menu, which lists the names of the respective audio and video contents. Related information, in addition, the program table can also carry the introduction of various audio and video content 200845755, or the essence of each audio and video content or preview. Similarly, the set-top box 120 will also load the aforementioned section from a specific channel and present it to the user through the playback device 13; for example, the user can select the desired item by the assistance of the program list. To view the inner valley, the set-top box 120 downloads the required audio and video content from the corresponding channel. For example, if the program list is a menu, then the user can use the button of the m or the set-top box to select the specific audio-visual content (the audio and video content 1), and then issue a download command to the machine. After the upper box 12〇, the set-top box 120 will start to download the aforementioned specific audio-visual content from the corresponding channel (CH1); the user can watch the selected audio-visual content after the entanglement + 4 to download the video. . It can be seen from the foregoing that the video and audio data dissemination system (10) of the present invention is not for the first two or two ("four" input" but for the video data prefabrication) (1) 122 (which is a non-immediate viewing machine / two) m "The demand for material width is not as strict as in the prior art, and its frequency is only enough to make the i 2 〇 cat ~ 士上 on the machine. The money on the dish 120 is downloaded in the scheduled time. Compared with the instant viewing mechanism provided by the prior art, the audio-visual data dissemination system (10) of the present invention provides a pre-recording mechanism for the user in the morning (four) m pre-recording mechanism. I want to watch the eyes, and when the user is working outside, the machine is on the 12th floor of the set-top box to download the work. When the clerk has gone down, the user will return to the ,, the set-top box is 12〇L: The user can watch the downloaded program. The pre-recording mechanism of this month is also characterized by: the system can be downloaded in the same way or not 10 200845755 to download some or all of the same channel to get the _ programΓ : content 'and at least - times or in addition, in view of General two: audio and video content. The wide range of video and audio data transmission systems of the present invention may be limited, and the audio data, rather than the network route to share the video data is being downloaded, not only the Beko transmission, and therefore, when the video is wide.曰Occupy the network frequency used originally, please note here, although in the above-mentioned set-top box 120 (such as the set-top box 1, the user is by choice, however, such two r: One embodiment of the invention, and the following: In the practical application, the present invention can also use other machines "9 (4) portable electronic products to select and / or play audio and video: the second is allowed to use The audio and video content can be performed at any time and place. Please refer to FIG. 2, which is a functional block diagram of the second embodiment of the audio-visual data dissemination system 200 of the present invention. The method is substantially the same as the above-mentioned video and audio data transmission system, and therefore will not be described here. Note that the video and audio data transmission system 200 is different from the aforementioned video data transmission system. The video data distribution system 200 provides the user with a different audio and video content subscription method. As shown in FIG. 2, the server 210 transmits the program list to the user-owned portable electronic product 240 (such as a mobile phone, Personal digital assistants (PDAs), laptops, etc., so that users can determine the audio and video content at any time and place through 11 200845755 14 portable electronic products. For example, the current market Most of the portable electronic devices 240 have the function of accessing the Internet on the left. Therefore, the server 21 can transmit the program list to the portable electronic device 240 by means of a network (such as mobile communication). The user can receive the program list through the various types of electronic devices 240 described above, and select the program. Then, in the embodiment, the portable electronic device 240 generates a load command and transmits the download command to the set-top box 22G, so that the set-top box 220 performs the corresponding download. The above mechanism should not be difficult for those who have common knowledge in this field; for example, the user can select a program through a mobile phone, and the mobile phone sends a short message, and when the news center receives the newsletter, Correspondingly, a download command is issued to the upper box 220; or the user can select a program through a notebook computer to enable the notebook to issue a download command and transmit the download command through the computer network. To the set-top box 22; such relativeization is also within the scope of the present invention. In other words, the present invention does not limit the manner in which the portable electronic device 240 communicates with the set-top box 220. The data transfer mode of the download instruction is only an embodiment, not a limitation of the present invention. In practice, the neutron device 240 can transmit the download command to the set-top box 220 by various means, for example, except for the above-mentioned computer network and all wired or wireless data transmission methods. It can be used as the transmission medium of the downloading finger', and these corresponding changes are all in accordance with the invention. 12 200845755 In addition, the present invention does not limit the type of the playback device 23, and only the set-top box 220 can be downloaded. The data can be transferred to the playback device 23 for playback. For example, if the aforementioned portable electronic device (such as a mobile phone, a personal digital assistant (PDA) or a notebook computer) and the playback device 23 have no problem in data transmission between each other, the aforementioned portable electronic device The device 40 is also used as the playback device 230; such a corresponding change is also a paradigm of the present invention. It can be seen from the foregoing disclosure that in the present embodiment, the present invention simultaneously integrates eight different technologies of eight broadcasts, weekly roads, and electric "communication to provide users with a brand new view mechanism; > Not only do users not be limited by time and space, they can choose the video and audio to be downloaded anytime and anywhere, and they can also watch the program anytime and anywhere through electronic devices such as mobile phones. In addition, the download method of the set-top box is also available. Innovatively, it receives the material through the antenna, and is not limited to receiving data through the computer network. This also relaxes the bandwidth limitation of the network. For a long time, no manufacturer has been able to integrate broadcast and network. And the technology of three different fields of telecommunications, at most, like Chunghwa Telecom integrates telecom operators and 1 network operators, can integrate the three and apply across these three areas, no one has done it in the past. It should be noted that although in the foregoing two embodiments, the present invention performs transmission of video and audio data by means of broadcasting, however, such an approach is an embodiment of the present invention. It is not a limitation of the present invention. In practical applications, the present invention can still transmit corresponding audio and video content through a computer network, and the corresponding change is also within the scope of the present invention. Further, although in the foregoing embodiments, the system is used for feeding. The server and user 13 200845755 data transmission architecture for data transmission, however, the present invention can achieve the same purpose through peer-to-peer (eer) transmission. For example, the foregoing audio and video content 5 can be stored in any network (4) (4) to achieve resource sharing by peer-to-peer (peer-t〇-peer); such corresponding change is also the present invention. category. Compared with the prior art, the present invention pre-stores the data required by the user in the set-top box in advance, in other words, the user does not view the audio-visual material in an instant manner, but is asynchronously For the viewing of audio and video data, the bandwidth requirement is relatively loose for the overall system, and high image quality is also allowed. In addition, the present invention simultaneously integrates the technologies of the broadcast 'network and telecommunications three different fields to provide a new viewing mechanism for the user' to allow the user to select the audio and video materials to be downloaded anytime and anywhere, and through electronic devices such as mobile phones. Watch the show anytime, anywhere. The present invention has been described above by way of examples, and the scope of the invention is not limited thereto, and various modifications and changes can be made by those skilled in the art without departing from the scope of the invention.
