Embodiment 2

[0075] Step 53: The terminal determines whether it needs to initiate the SG update process according to the received SGDD, and executes step 55 or 59.

[0076] When the terminal checks the obtained SGDD, it checks the "DescriptorEntry" entry in the SGDD. At this time, the terminal can parse specific information under "AlternativeAccessServiceGuideDeliveryUnit" and "ServiceGuideDeliveryUnit". In this example, it is considered that SGDU's description of available SG fragments is separated. Then, the terminal will determine whether there are broadcast SG fragments and interactive SG fragments that need to be updated for both.

[0077] Step 55: The terminal determines whether it needs to obtain the broadcast SG through the broadcast network. If it needs to obtain the broadcast SG through the broadcast network, go to step 57; otherwise, go to step 513.

[0078] Step 57: Obtain the broadcast SG that needs to be updated through the broadcast network, and perform step 513.

Abstract

The embodiment of the invention relates to a sending method, an acquiring method, a server, a terminal and a system of a service guide. The sending method of the service guide comprises: generating a service guide delivery descriptor SGDD, wherein the SGDD comprises description information of an interactive service guide, which is provided for the terminal to determine whether acquiring the service guide via an interactive network or not; and sending the SGDD to the terminal. The acquiring method of the service guide comprises: acquiring the SGDD comprising the description information of the interactive service guide according to the received service guide delivery descriptor SGDD; and acquiring the service guide via the interactive network when the description information of the interactive service guide satisfies the preset conditions. The embodiment of the invention is advantageous to a terminal in an interactive or fusion network to improve the efficiency of acquiring the SG via the interactive network.

Description

Technical field [0001] The embodiments of the present invention relate to communication technology, and in particular to a method for sending, obtaining a service guide, a server, a terminal, and a system. Background technique [0002] To provide a unified service platform for mobile video broadcasting, the Open Mobile Alliance (Open Mobile Alliance, referred to as OMA) has proposed a new mobile broadcast service (Mobile Broadcast Services, referred to as BCAST) system. In the BCAST system, a service guide (Service Guide, SG for short) includes multiple data fragments; one or more data fragments are encapsulated into a Service Guide Delivery Unit (SGDU for short). The generated Service Guide Delivery Descriptor (SGDD) describes the multicast session information corresponding to the file distribution session for sending the SGDU, and is used to provide updated description information of the SG and its obtaining method. When the SG information on the server is updated, the termina...
