New description: [New technology field] This creation department is about a multi-layer content delivery control system, especially a kind of pre-recording audio and video data on the user side to avoid the network quality of the service provider to affect the user side. Multi-layer content delivery control system for audio and video viewing quality. [Prior Art] With the continuous advancement of the Netcom industry, modern people's work, business, shopping, news, etc. in the daily life can be combined with network communication technology, so that modern people can be in the first time, Master the news of every corner of the world. Therefore, network communication technology has become an indispensable part of the lives of modern people. At the same time, as the network has the function of entertainment and growth, with the rapid development of network technology, the combination of traditional TV and network is regarded as one of the development trends of the next wave of network applications. As mentioned above, Internet Protocol TV (lntemetprot〇c〇1 Televisi〇n, Ιρτν for short) is a system for transmitting television information using a broadband network as a medium. By definition, ιρτγ service providers transmit a variety of interactive multimedia services, including digital TVs, to the terminal devices of the subscribers via video over broadband protocols. In general, the terminal equipment of IPTV can be electronic products such as computers, televisions, mobile phones, information appliances, pDA, etc., but when the ιρτγ terminal device is a normal TV, it needs to be paired with an Internet set box (Internet Protocol Set- Top-Box, referred to as IP STB), receives channel and conversion signals. The above video stream can be divided into two types: broadcast (Broadcast) and video on demand (v〇D). Among them, 'on-demand video is a user-led video selection system, that is, the user can select the desired video program when and wherever, and arbitrarily control the playback mode of the video program. This on-demand video technology has broken the passive 'time constraints', spatial limitations and low selectivity of traditional video programs, and has indeed received great attention in recent markets. For example, the user terminal device is used as a TV. As mentioned above, "on-demand video broadcasting, the technology system uses streaming to achieve", that is, the user of the set-top box presents (10)*2· and the playback request to the ship terminal. After the server end recognizes that the set-top box can play the movie, it can instantly transfer 3 M442660 audio and video data to the on-board ^' box to play the video and audio through the screen. During the playback process, various control commands issued by the user terminal will be sent via the set-top box, and after receiving the command, the server will respond to the movie according to the command. However, this kind of age has no shortcomings, and the low willingness to use it limits the speed of IPTV's comprehensive expansion: (1) The ship end needs to provide a network connection for each-box user. When multi-side households are connected and playing at the same time, in addition to the multiplication of the number of bandwidth users, the read and write performance of the shipboard side must be multiplied. Based on the above usage, the equipment cost of the "service provider" will increase significantly. (2) The content provided by the ship-side streaming architecture is often played due to the performance reasons or faults of the ship end and the quality factors of the network nodes that pass through, resulting in poor quality of the user terminal during playback or even interruption of playback. situation. (3) With the evolution of technology, Na's picture quality is getting higher and higher, which means that the network must provide more bandwidth, and the higher audio and video content can be instantly transmitted to the set-top box. Therefore, when the bandwidth is limited, the high image (4) picture cannot be transmitted in real time, which affects the image quality. [New content] In view of this, this creation provides a multi-layered content delivery control system, which can store audio and video data in the user's side in advance. When the user sees the internal material, it can directly click and play, without being subject to the meaning of Road quality. (4) As the system provided by this creation is to hand over the video and audio information to the user terminal, the ship's ship load can be reduced by the ship to further meet the low frequency and high demand quality optional video service. . One of the purposes of this creation is to provide a multi-layered content delivery control system for controlling the number of data to be self-riding to provide a t-side ship to a plurality of fine ends. The above-mentioned layered content includes at least one remote ship, at least one relay word machine and a plurality of machine upper boxes. The remote vehicle is disposed at the service provider end and can be connected to the relay feeder through a first network transmission interface and actively deliver the data to the medium paste device. A plurality of set-top boxes are provided with a first storage material, and the relay buffer can connect the upper cassette through a 4th M442660 second-age network and transfer the mixed materials to the set-top boxes. . The data is stored in the first storage unit of each box. In an embodiment of the present invention, the set-top box further includes a playing unit, and the playing unit is connected to at least the final viewing device. The playing unit of the set-top box that is controllable by the user terminal can play the data through the terminal device by the user. One of the ends is selected. In the present invention, the terminal device can display a screen for a television or an electronic device.

interface, and the second network transmission interface is a regional network transmission interface. In the embodiment of the present invention, wherein the data is a plurality of video and audio information, the content of the program is further described in the following description, and the features and advantages of the present invention can be further read. For reference, please refer to the first to third. Figure. [Embodiment] Please refer to the first and second figures. The first figure is a schematic diagram of the architecture of the multi-content transmission control system of the preferred embodiment of the present invention, and the second _ is used for further description. The architecture's therefore omits some of the repetitive components in the second @, which are described first. First, 5 M442660 As shown in the first figure, this creation provides a multi-layered content delivery control system to control the transfer of multiple data from the service provider to multiple clients. The multi-layer content management system includes at least one remote server 10, at least one relay server 20, and a plurality of set-top boxes 30, 3, 32, and 33. The remote server 10 is disposed at the service provider end and can connect to the relay server 2 through a first network transmission interface and actively transfer the data to the relay server 20. A plurality of set-top boxes 30, 31, 32, and 33 are respectively disposed at respective users. In a preferred embodiment, the set-top boxes 30, 31 and the set-top boxes 32, 33 can be divided into two regional type cluster users. For example, the set-top boxes 3, 31 belong to a building. Two users, while the set-top boxes 32, 33 belong to two units in the company. At this time, the relay server 20 can be connected to the set-top boxes 3〇, 31 through the second network transmission interface 2〇〇a, and also connected to the on-board through another second network transmission interface 2Q〇b. The cassettes 32, 33 actively transfer the data to the set-top boxes 30, 31, 32, 33p. In a preferred embodiment, the set-top boxes 30, 31 further comprise a playback unit 3〇4, 314, and as in the first As shown, the set-top boxes 30, 31 are respectively connected to the terminal devices 40, 41, and the user terminals having the set-top boxes 30, 31 can control the playback units 3, 4, 314 of the set-top boxes 30, 31 through the terminal device 40. , 41 plays one of the data selected by the user. That is to say, when the data transmitted by the remote server is a plurality of programs, the user terminal can select the program they want to watch by controlling the playing unit of the set-top box, and finally play by the terminal device. Preferably, the terminal device can display a screen for a television or an electronic device, but this creation is not intended to be limited thereto. Referring to the second figure, the remote feeder 10 further includes a first active content delivery unit 103. The first active content delivery unit 103 actively initiates according to the first bandwidth condition of the first network transmission interface. The information is transferred to the relay server 2〇. That is to say, when the bandwidth of the first network transmission interface 1GG is sufficient and the overall network product f is good, the remote server 10 will transfer the data to the relay server at this time. On the other hand, if the overall network quality is not good, the remote server will stop transmitting data or transmit less data. At this time, the information provided by the service provider can be temporarily stored at the remote end. In the second storage unit 1〇2 of the server 1,, after the overall network quality of the first-network transmission interface 丨(8) is stabilized, ^ (4) hand-made 'into-step-down health-end feeding device 1 () Similarly, the 'the relay ship includes the second storage unit 2〇2 and the first content receiving unit 6 204'. The first content receiving unit 2〇4 receives the first active content delivery unit of the remote server 1 The data transmitted by the 103 is confirmed and the integrity of the data is confirmed, and the second storage unit 202 stores the data. In addition, the relay server further includes a second active content delivery unit 203, and the second active content delivery unit actively transmits the data to the machine according to the second bandwidth condition of the second network transmission interface The upper box is 3〇, 31. As described above, when the bandwidth of the second network transmission interface 200 is sufficient and the overall network quality is good, the relay server 20 transmits the data to the set-top boxes 3, 31 at this time. On the other hand, if the current overall network borrows, the side of the towel will stop transmitting or pass less. At this time, the data transmitted from the remote server 10 may be first stored in the second storage list το 202, and the data is transmitted to the machine after the condition of the second network transmission interface 2 is stabilized. Upper box 30, 3 _ Please continue to refer to the second figure, the remote feeder 10 also includes a - user identification unit 104. Basically, the setting for a single client or all users can be set by the service provider on the remote $(4)10, for example, why the audio content of the A user's miscellaneous touch is 'or; I: a certain regional cluster What is the audio and video content that the user can play? At this point, you can use the user identification list; ^1 () 4 to determine which data rooms to transfer to which users, and transfer the data content of the above settings - and to the towel _ county 2G, and stored in the relay servo The second storage unit 2 is in the second storage unit 2〇2. - As shown in the second figure, the set-top boxes 30, 31 respectively include - a second content receiving list = 303, 313, and the second content receiving unit 3 〇 3, 313 is used to receive the relay servo The data transmitted by the first active content delivery unit 2〇3 of a0. The most important thing is that the set-top boxes 30'3 32, 33 have - the first storage unit 3 〇 2, 312 (the second m ^ ^ green read · upper box 32, 33 detailed structure), the second content After receiving the data, the receiving unit 303 can store the data in the first storage unit 312 of the on-board box and the first storage unit 312 of the set-top box 31, and store the data. ^ 识, return to the middle _ server 2 (), to complete the process of data transfer. The step indicates that the '# client needs to confirm that it has the current storage of two grays, for example, a movie in the set-top box, and can send a clear user to the relay server through the set-top box. After the user sends out the list request, he can reply to the box on the user side according to the video that is viewed every 1 month. At this point, use the M442660 client to connect to (4) this list, then you can enter the video you want to view. The playback unit of the box will be stored directly in the storage unit itself. Rely on the connection to the relay server until playback stops. In the following, in addition to the video and audio data transmission process exemplified above, the service provider can also carry out different maintenance control of the multi-layer content delivery system in the Silk Island. For details, refer to the second figure, the remote vehicle. 1G further includes - the user command unit server 2 includes - user content control unit plus, and the set-top box 3G, including - command execution units 305, 315. When the service provider wishes to issue a - (four) command (for example, a tablet) to a specific machine box (here, the box is called "3"), the user command unit 1〇5 of the remote feeder 10 It will search for the relay server to which the two ends belong (here, the relay server 2), and send the control command to the secondary server 20, and the relay server 2 receives After the control command, the smart box unit 205 is used to the set-top box 3. Release the control command, at this time on the box 3. The command execution unit 3〇5 will perform a corresponding action according to the control command, that is, the movie ^second storage unit 302 is deleted. After the deletion is completed, the user box will return the ^ to the towel_county. If the user requests the viewing, the returned movie list will not have the content of the movie. In the preferred embodiment, the service provider provides control commands for the user and the user. In addition to "striping the shelf", there are functions such as "reboot", "switch specific interface", and "specified message transmission". However, regardless of the above-mentioned control command, the second can be used to transfer the control command from the remote ship II to the relay ship, and then transmitted to the relay ship by the relay ship. The second box of the end is used, and the set box of the user end makes a phase or action according to the received control command. In the preferred embodiment, the information may be a plurality of video information or a plurality of program content. In addition, the first network transmission interface is a wide area network transmission interface, and the second network transmission interface is a regional network transmission interface, such as a wireless area network, a Bluetooth wireless network, an infrared network, or an Ethernet network. Road and so on. " The architecture of the multi-layered content delivery control system provided by this creation has been roughly explained as before. The following figure will be further combined with the third figure to illustrate the control method of the multi-layer content delivery 8 M442660 control system provided by this creation. Please refer to the third figure. The third figure is a flow chart of the control method of a preferred embodiment of the present invention. First, the service provider first sets the data content to be transmitted on the remote server, and then the remote server actively transmits the data to the relay according to the bandwidth condition of the first network transmission interface. After the relay server receives the data S42, the server 84 must confirm whether the data received by the server is complete. If not, that is, if the remote server is still transmitting data, the whole process will be Returning to step S42, the integrity of the data is verified repeatedly. Then, if so, the relay server stores the data in S44. Then, the relay server actively transmits the data to the set-top box S45 of each client according to the bandwidth condition of the second network transmission interface. At this time, the set-top box receives the data S46 and repeatedly confirms the integrity of the data S47. When the set-top box judges that the data has been completely transmitted and received, it stores the data in a storage unit S48. ~ Although not shown, in the preferred embodiment, the control method provided by the present invention further includes the following steps: when the user requests a list request to the relay feeding device, the relay feeding device is based on the user terminal. The list requirements and a list of the contents of the information are provided. At this time, after the set-top box receives the list provided by the relay servo i, the user can still control the box according to the list to selectively view any of the materials. In addition, as mentioned above, service providers can also use the multi-layered content delivery mechanism provided by this creation to control the data in the on-board box of the client. Therefore, the control method provided by this creation further includes the following steps: First, the remote ship receives control commands from the service provider. The 'remote server then passes control commands to the relay server, and the relay ship passes control commands to at least one of the set-top boxes. Finally, at least one of the set-top boxes performs one of the actions corresponding to the control command in accordance with the control command. In the preferred embodiment, the Laihu command blush action includes at least a _ mis-delete action, a -reboot action, a switch specific interface action, or a specified message transfer action. In summary, the multi-layered content delivery control system provided by the author enables the user to have the video at the local end while watching the video, that is, the network quality and the ship support power are completely eliminated during playback. Provide smooth, high-quality audio and video services. Therefore, based on this feature, the video selected by the user already exists on the local end. In the conventional technology, problems such as network transmission speed and stability, server J/0 and computing power will no longer affect the 9 M442660 ringing video. Play quality. Moreover, the service provider only needs to control the delivery speed and the amount of users according to the overall performance of the system, and relatively reduces the cost. In short, the functions of this creation are organized as follows: (1) According to the attributes of the user group, combined with the transmission combination of the Internet and the regional network, the purpose of saving bandwidth costs can be achieved, and the limited Internet can be effectively utilized. The bandwidth, through the combination of regional network architecture, achieves the goal of unlimited users. (2) The system provides a complete set of playback and management system for the set-top box with storage device. The content of the audio and video is delivered to each set-top box via the server-side content delivery method, and the user can play the saved file. The content, that is, when the audio and video content is played on the box, because it has been disconnected from the network demand, it will eliminate the abnormal playback quality and fault tolerance of the video due to the server and network quality. Therefore, this creation can be effectively applied to users who need to play South-quality audio and video, such as: travel hotels, educational units, hospital wards, etc. (3) As stated in point (7), since the user has watched the movie, the film has completed delivery = video, can be repeatedly viewed, and performs various manipulations on the movie, such as: fast forward, rebroadcast, pause play, etc. De, not copper to any bandwidth. (:) Service providers will be able to provide a variety of dimensions to each client via the central end to facilitate control. Even the service provider's communication device on the service provider can also manage the operation of each client-side between the lights and the mobile terminal without any space restrictions.
