Problems solved by technology

However, to achieve large-scale applications, a large number of edge servers need to be deployed, which is very expensive
Therefore, the main disadvantage of the current streaming media on-demand system of the client / server mode that connects the TV set to the computer network to realize streaming media on-demand is that the system has poor scalability and high cost.
[0006] To sum up, the existing TV-based streaming media on-demand system has the disadvantages of limited programs available for users to order and poor system scalability.

Embodiment 1

[0041] A central server is deployed in the computer network, and all televisions are connected to the computer network, as shown in Figure 1. When TV i plays the video on demand movie "M", it first interacts with the central server, and the central server selects TV k to provide services for TV i according to the selection strategy according to the storage situation of the current movie "M" and the current playing status , as shown in Figure 2, the request / response interaction between TV i and the central server when ordering, the central server selects the TV k as the server, and TV i establishes a connection with TV k according to the instructions of the central server, and The media file "M" is sequentially transmitted from TV k, as shown in FIG. 3 , the transmission direction of the media file is from TV k to TV i. As shown in Figure 4: when TV c plays the video-on-demand movie "M", it first interacts with the central server, and the central server selects TV g according t...

Embodiment 2

[0043] The invention provides a streaming media on-demand system using a TV set as a server, comprising a central server deployed in a computer network, at least one router connected to the central server, a switch connected to the router, and a switch connected to the at least two TV sets on the switch; the central server includes the address of the TV set storing files, the resource status of the TV set, the storage space of the TV set, the computing power and utilization rate of the TV CPU, and the uplink bandwidth and utilization rate of the TV set , the TV information module of the TV play directory name and the program download percentage; the TV with IP address includes an embedded real-time operating system, a storage medium, various information of the TV and the information on the TV information module corresponding to the information. The central server includes a streaming media database, and the streaming media database at least includes a catalog of streaming medi...

Embodiment 3

[0045] The present invention also provides a streaming media on-demand method using the TV as a server:

[0046] A. Deploy a central server in the computer network;

[0047] B. Multiple televisions connected to the central server and connected to the computer network;

[0048] C. The central server compares the information parameters currently displayed by any TV on the TV information module of the central server, and selects any TV to provide services for any other TV.

[0049] The selection strategy in step C is: 1) random selection; 2) maximum remaining bandwidth selection strategy; 3) minimum delay selection strategy; 4) minimum depth selection strategy; 5) selection strategy and comprehensive strategy based on user history behavior.

Abstract

The invention discloses a streaming media on-demand system which takes a television as a server, and comprises a central server arranged in a computer network, at least a router connected with the central server, an exchanger connected with the router, and at least two televisions connected on the exchanger. The central server comprises a television information module for storing files of television address, television resource state, television storage space, television CPU computing power and utilization factor, television uplink bandwidth and utilization factor, television broadcasting list names and program downloading percentage; the television with an IP address comprises an embedded real-time operating system and a storage medium, and various information correspond to the information on the television information module. The television of the invention not only can be used as a client terminal to store programs for the local users, but also can be used as the server, thus the invention has the advantages that the program source is rich, and the expandability is good.

Description

technical field [0001] The present invention relates to the technical field of streaming media services, in particular to a streaming media on-demand system and method using a television as a server under a computer network environment. Background technique [0002] Traditional TVs can only "push" specific content to users, and users cannot arbitrarily choose the movies they want to watch. The design goal of the video-on-demand system is to provide users with pre-saved program-on-demand services at any time, and to support interaction with users. [0003] In the TV-based streaming media on-demand system, there are two most commonly used ways to access the network. One is to connect the TV set to the cable TV network to realize streaming media on demand, and the other is to connect the TV set to a computer network (such as the Internet) to realize streaming media on demand. [0004] It is rare to connect a TV set to a cable TV network to realize streaming media on demand. ...
