Abstract

Embodiments of the present invention disclose a Service Guide (SG) sending method, an SG acquiring method, a server, a terminal, and a system. The SG sending method includes: generating a Service Guide Delivery Descriptor (SGDD) that includes interactive SG description information as a basis for a terminal to determine whether to acquire an SG through an interactive network; and sending the SGDD to the terminal. The SG acquiring method includes: according to a received SGDD, acquiring interactive SG description information included in the SGDD; and acquiring the SG through an interactive network if the interactive SG description information fulfills preset conditions.

Claims

1. A Service Guide (SG) sending method, comprising:

generating a Service Guide Delivery Descriptor (SGDD) that comprises SG description information as a basis for a terminal to choose whether to acquire an SG through an interactive network; and

sending the SGDD to the terminal.

2. The SG sending method according to claim 1, wherein:

the SG description information comprises description information indicating whether any updated SG exists on the interactive network.

3. The SG sending method according to claim 1, wherein:

the SG description information comprises description information of an updated SG on the interactive network.

4. The SG sending method according to claim 1, wherein:

the SG description information comprises description information indicating whether the interactive SG comprises any fragments other than a broadcast SG.

5. A Service Guide (SG) acquiring method, comprising:

according to a received Service Guide Delivery Descriptor (SGDD), acquiring SG description information comprised in the SGDD; and

acquiring the SG through an interactive network if the SG description information fulfills preset conditions.

6. The SG acquiring method according to claim 5, wherein:

the SG description information comprises description information indicating whether any updated SG exists on the interactive network; and

the preset conditions comprise a condition where the interactive SG description information indicates that an updated SG exists on the interactive network.

7. The SG acquiring method according to claim 5, wherein:

the SG description information comprises description information of an updated SG on the interactive network; and

the preset conditions comprise a condition where description information of the updated SG on the interactive network differs from stored SG description information.

8. The SG acquiring method according to claim 5, wherein:

the SG description information comprises description information indicating whether the interactive SG comprises any fragments other than a broadcast SG; and

the preset conditions comprise the interactive SG description information indicates that the interactive SG comprises fragments other than the broadcast SG.

9. A server, comprising:

a generating module, configured to generate a Service Guide Delivery Descriptor (SGDD) that comprises SG description information as a basis for a terminal to choose whether to acquire an SG through an interactive network; and

a sending module, configured to send the SGDD to the terminal.

10. A terminal, comprising:

a description information acquiring module, configured to acquire, according to a received Service Guide Delivery Descriptor (SGDD), Service Guide (SG) description information comprised in the SGDD; and

an SG acquiring module, configured to acquire the SG through an interactive network if the SG description information fulfills preset conditions.

11. A Service Guide (SG) processing system, comprising:

a server, configured to generate a Service Guide Delivery Descriptor (SGDD) that comprises SG description information; and

a terminal, configured to acquire the SG through an interactive network if the SG description information fulfills preset conditions.
