Embodiment 1

[0065] The cross-platform distributed network controllable multimedia playback method of this embodiment can be based on such as figure 1 A typical cross-platform distributed network shown in figure 1 In the mid-span platform distributed network, its backbone network is mainly the Internet. Devices on different platforms can access the Internet in different ways: Ethernet devices such as computers, set-top boxes and digital information appliances (for example: HDV players with network access functions, For details, see the applicant's unpublished prior application: 200510053907.5), connect to the Internet through broadband access methods such as static IP access of LAN, dynamic allocation of IP access through routers, and ADSL dial-up access. Center, GPRS, WAP site and 802.11 wireless base station connection server (called bridge setting in the figure) connect to the Internet. Devices in other networks can access the Internet through bridge devices. All the above devices conn...

Embodiment 2

[0084] The above embodiment 1 does not further explain the source of the relevant programs. The client node can upload its own files and programs, and establish end-to-end connections with other client nodes through the unified management of the index server. However, such a method will cause a large number of illegal Programs enter the network, so in order to form a benign broadcasting method, the method in this example can be further optimized, that is, to intentionally control the source of the files or programs transmitted between each other, the authorized files or programs can be stored on the index server, and the network At first, the client node can only directly obtain the required file or program from the index server, and then the client node can also serve as a server to provide the program to other clients, so in the above S21 step, the index server can provide the file when searching When the user node of the client node, only search in the client node that has l...

Embodiment 3

[0088] Other conditions can be the same as the above embodiment, but in the above example, all client nodes can transfer files or programs to each other, but since the client nodes here are cross-platform devices, in order to coordinate communication services between devices on different platforms , for a computer with strong connection and communication performance, its uplink and downlink ratio can be continuously adjusted to balance the communication between the entire network equipment, that is, to give priority to the function of an intermediate server. For devices with relatively weak connection and communication performance, such as set-top boxes, the ratio of uplink to downlink is relatively stable, and can also be adjusted in batches according to network conditions. For mobile phones and other network terminals that require a relatively small amount of data, it is mainly used as a client. In addition, the connection channel between mobile phones is very stable, which i...

Abstract

A method for playing network controllable multimedia of transplatform distributed type includes sending program application information to central system by application client node requiring program, searching one or multiple program node of file matching to said application information in its databank by central system according to said application information and sending searched result to application client node, setting up end to end connection of application client node to one or multiple program node in order to receive file. The device for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to a playing method, in particular to a digital multimedia cross-platform distributed network controllable playing method, and also relates to a device for realizing the playing method. Background technique [0002] Ordinary multimedia playback devices or playback terminals, specifically, the current DVD player, has no network interface, cannot obtain programs from the Internet or a local area network, and cannot realize the function of a network playback terminal; Access and on-demand applications consume huge server resources, and large-scale services cannot be realized on public networks such as the Internet. For example, if the uplink bandwidth of a server is 100M BPS, and each user's order occupies 1-4M BPS, then a server can only support 25-100 concurrent users at most. Since the traditional server only provides data uploading and very little downloading data, and when users watch or download programs, the downloading data ...
