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 ...
