Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] The principle of the present invention is based on the fact that in DVB-H, the playback of a certain channel program only needs a scene description protocol (SDP, Session Description Protocol) file with a size of about 1K bytes. The present invention adds preset SDP information to the content of the access descriptor (Access Descriptor) in the DVB_H protocol, such as the a099.tm3348r2.cbms1199r14 protocol, so that the DVB_H handheld terminal can be operated before receiving ESG data. The SDP information preset by the provider, and play the channel corresponding to the SDP information, and receive ESG data in the background at the same time, so that the user can quickly enter the video playback, such as quickly enter the mobile TV playback, avo...

Abstract

The present invention provides a method, a system and a device to start video play under DVB-H net work. The method comprises generating an access descriptor that contains preset SDP information at the DVB-H network; accessing and playing the descriptor of contained SDP information; step 3, accessing the DVB-H terminal into the descriptor and resolving the SDP information from the descriptor; step 4, the DVB-H terminal broadcasting video programs corresponding with the SDP information with the resolved SDP information. The DVB-H terminal consists of: a resolve module and a play module that are connected with the descriptor. The system of the present invention consists of the terminal of the present invention and a DVB-H network terminal that is provided with a generating module of access descriptor and a broadcasting of access descriptor. The present invention can realize fast start of video under DVB-H network, prevent long time waiting interface and greatly improve the experience of consumers.

Description

technical field [0001] The present invention relates to the technical field of digital video broadcasting (DVB-H, Digital Video Broadcasting Handheld), in particular to a method, system and device for starting video playback under a DVB-H network. Background technique [0002] With the popularization of the third generation mobile communication (3G, Third Generation) technology in the world, more and more users start to watch mobile TV through the 3G network. Operators soon discovered that more users watched TV on 3G networks, which not only took up valuable 3G bandwidth, but also brought high charges to users. DVB-H is a terrestrial digital TV broadcasting technology for handheld terminals. The network construction cost is small, and the one-way broadcast does not occupy the two-way bandwidth of the mobile communication network. It allows users to watch TV anytime, anywhere and at a very low price. . [0003] In the prior art, if a user wants to use a mobile handheld term...
