Abstract

The present invention relates to a video program-requesting method, a device and a system. The method comprises the following procedures: requesting the television program module service according to the terminal attribute and receiving the program menu, wherein, the terminal attribute comprises a network and a medium format which are supported by the terminal; receiving the television program module according to the obtained correlative information and the electric program list generated according to the attribute of the terminal, wherein the correlative information is generated according to the association relationship between the medium content and the medium format; and generating the requirement information according to the electric program list and transmitting the requirement information. The invention separates the exhibiting logic from the scheduling logic through the mode that the URL which is transmitted by the service end according to the terminal requirement information and the network load after the receiving the electric information list that is generated basing on the correlative information. The terminal is facilitated to receive the corresponding service through the network with little load under the scheduling logic of the service end. The defect of low using efficiency of network in the existing technique is overcome and the video program requesting with high network using efficiency is realized.

Description

technical field [0001] The invention belongs to the field of video and audio processing, in particular to a video-on-demand method, device and system. Background technique [0002] Video on demand (Video on Demand, hereinafter referred to as VOD), also known as interactive TV on demand, is a service that plays video programs according to the needs of the terminal, which fundamentally changes the defect that the terminal can only passively receive video programs in the past. . [0003] Existing VOD method is as follows: business management system (Business Manage System, hereinafter referred to as BMS) informs VOD system to download media content; According to the media content downloaded by VOD system, TV program module (Electronic Program Guide, hereinafter referred to as EPG) generates Electronic program list, the electronic program list only contains the one-to-one correspondence between media content and media format; after the terminal selects a TV program, it directly...
