Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042]The embodiment of the invention discloses a method and system for acquiring service information. In the CMMB front-end system, the audio elementary stream, video elementary stream, and data stream of the same service are encapsulated in the same multiplexed subframe, auxiliary information such as ESG and user management are encapsulated in different multiplexed subframes, and control information Encapsulated in a dedicated multiplex frame. Wherein, each...

Abstract

The invention discloses a method, a device and a system for acquiring service information. In the method and the device, a server adds the service information in control information of all preset frequency points; a terminal scans all the frequency points, determines target frequency points and sends a request for acquiring control information corresponding to the target frequency points to the server; the server feedbacks the service information in the control information corresponding to the terminal according to the request of the terminal; and the terminal analyzes the acquired control information so as to obtain the service information corresponding to the target frequency points. In the invention, time related to ESG (electronic service guide) is omitted in the process of acquiring the service information, so that not only is the needed ineffective time for acquiring the service information reduced, but also the data volume is reduced, the influence of network error codes on thetime for acquiring the service information is reduced, further a user can acquire the needed service information fast, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, relates to a method, device and system for obtaining service information by a CMMB (China Mobile Multimedia Broadcasting) mobile phone TV. Background technique [0002] China Mobile Multimedia Broadcasting (CMMB, China Mobile Multimedia Broadcasting) uses high-power S-band satellite signals to cover the whole country, uses ground supplementary transponders to forward satellite signals at the same frequency and content at the same time to cover satellite signal blind areas, and uses wireless mobile communication networks to construct backhaul channel, thus forming a mobile multimedia broadcasting network combining one-way broadcasting and two-way interaction. CMMB specifies the frame structure, channel coding and modulation of broadcast channel transmission signals in the mobile multimedia broadcasting system within the frequency range of the broadcastin...
