Problems solved by technology

[0010] 1. When there is a lot of ESG content, the server needs to send a message containing a large amount of data to the terminal at one time, which will greatly increase the probability of transmission errors and reduce the reliability and efficiency of transmission;
[0011] 2. When the response message returned from the server is large, it will have a great impact on the processing capability of the terminal; and only after receiving all the content of the response message can it be processed and displayed to the user, resulting in a large display delay. low processing efficiency;
[0012] 3. The terminal may have saved some fragments, but still needs to receive all the fragments from the response message, causing the terminal to perform unnecessary processing and waste the resources of the terminal

Embodiment 1

[0111] In this embodiment, assuming that the terminal does not have any ESG fragments locally, the terminal first requests a complete ESG from the ESG server; when the terminal requests fragments from the ESG server according to the fragmentation information list returned by the ESG server, each time the terminal specifies the required Fragmentation.

[0112] FIG. 3 is a flow chart of signaling interaction for transmitting an EPG according to Embodiment 1 of the present invention. Referring to Figure 3, the signaling interaction process includes the following steps:

[0113] Step 301: the terminal requests the ESG server to obtain the ESG through the interactive channel.

[0114] Step 302: The ESG server determines the associated fragments to be sent according to the ESG requested by the terminal, and constructs a fragment information list with the determined fragment information to be sent.

[0115] Step 303: the ESG server returns a response message carrying a list of frag...

Embodiment 2

[0172] In this embodiment, the terminal first sends a conditional query request to the ESG server to query ESG information that meets the conditions; when the terminal requests fragmentation from the ESG server according to the fragmentation information list returned by the ESG server, the required fragmentation is specified each time .

[0173] The basic steps of the ESG transmission method in this embodiment are the same as the basic steps of the method shown in FIG. 4 in Embodiment 1. Therefore, please refer to FIG. 4 for the flow chart of the method in this embodiment. The method for transmitting the ESG in this embodiment includes the following steps:

[0174] From step 401 to step 402, the terminal starts the mobile video software to obtain the address of the ESG server.

[0175] In step 403, the terminal sends a condition query request to the ESG server, requesting to query program information meeting specific conditions. In this step, please refer to the prior art fo...

Embodiment 3

[0191] In this embodiment, the terminal first requests a complete ESG from the ESG server; when the terminal requests fragmentation from the ESG server according to the fragmentation information list returned by the ESG server, it only sends a fragmentation request message to the server once to inform the server that the terminal has saved the fragmentation information. fragments, or fragmentation information that the terminal does not have, and the number of fragments that the terminal requests the server to return, the server decides which fragments to send to the terminal, and each time the terminal receives the fragments sent by the server, it sends return confirmation message

[0192] FIG. 5 is a flowchart of a method for transmitting an electronic program guide according to Embodiment 3 of the present invention. Referring to Figure 5, the method includes terminal processing and server-side processing, specifically, the following steps:

[0193] The operations performed ...

Abstract

This invention discloses a method for transmitting electronic program directories including: a terminal sends a request with ESG information to a server, which determines being sent slices relating to the ESG based on the ESG information in the request and sends the slice information of all being sent slices to the terminal, which receives it from the server and carries part of the information in the request information and sends it to the server to send them to the terminal in many times.

Description

technical field [0001] The invention relates to mobile video broadcast technology, in particular to a method and system for transmitting an electronic program guide. Background technique [0002] Mobile video broadcasting service is a new type of mobile service that transmits video content to mobile users through broadcasting network, mobile network and mobile terminal. [0003] Electronic Service Guide (ESG for short) is a very important application layer technology in mobile video broadcasting. ESG provides a direct user interface for users to view information about various businesses, browse video channels and program lists, browse price lists, select and purchase one or more items in the price list, and log in to the website to browse web pages, etc. and access guide. ESG is composed of many different types of fragments according to their inherent logical relationship. Usually, one program information is associated with multiple fragments, and ESG is processed by fragm...
