Abstract

The present invention discloses a method, an apparatus, and a communication system for transmitting graphic information. In the technical solution of the present invention, the graphic information carries a hyperlink and an identifier of the hyperlink so that when the terminal receives the graphic information, the terminal may judge, according to the identifier of the hyperlink, whether the hyperlink has been processed, and the terminal requests the graphic from the network according to the hyperlink only when determining that the hyperlink has not been processed, therefore ensuring an effective decrease in bandwidth consumption of broadcast or multicast channels, effectively avoiding repeated processing and presentation of a same hyperlink by the terminal, and reducing the complexity of the processing of the terminal.

Claims

1. A method for transmitting graphic information, comprising:

acquiring graphic information, wherein the graphic information carries a hyperlink and an identifier of the hyperlink;

judging, according to the identifier of the hyperlink, whether the hyperlink has been processed; and

when determining that the hyperlink has not been processed, acquiring a graphic from a network according to the hyperlink, and presenting the acquired graphic according to the graphic information.

2. The method according to claim 1, further comprising:

when determining that the hyperlink has been processed, acquiring a graphic corresponding to the hyperlink locally, and presenting the acquired graphic according to the graphic information.

3. The method according to claim 1, wherein:

the judging, according to the identifier of the hyperlink, whether the hyperlink has been processed comprises;

judging whether an identifier recording table has an identifier that is the same as the identifier of the hyperlink;

if an identifier recording table has an identifier that is the same as the identifier of the hyperlink, determining that the hyperlink has been processed; and

if an identifier recording table does not have an identifier that is the same as the identifier of the hyperlink, determining that the hyperlink has not been processed;

the determining that the hyperlink has not been processed further comprises;

recording the identifier of the hyperlink in the identifier recording table.

4. The method according to claims 1, wherein the acquiring the graphic information comprises:

receiving a graphic stream sent by the network, wherein the graphic stream is carried by means of a Real-time Transport Protocol (RTP) and is independent of a video content transmission stream; and

parsing the graphic stream and judging which one is carried in the graphic stream, graphic or graphic information, and if the graphic information is carried, acquiring the graphic information.

5. The method according to claims 1, wherein:

the graphic information further carries presentation position information; and

the presenting the acquired graphic according to the graphic information comprises;

determining a presentation position of the graphic according to the presentation position information in the graphic information and displaying the graphic at the presentation position.

6. The method according to claims 1, wherein the graphic information further carries presentation time information;

and

after the presenting the acquired graphic according to the graphic information, the method further comprises;

stopping presenting the graphic when determining, according to the presentation time information in the graphic information, that the presentation time of the graphic expires.

7. The method according to claims 1, wherein the graphic information further carries temporarily saving time information;

and

after the presenting the acquired graphic according to the graphic information, the method further comprises;

saving the graphic in a register when determining, according the temporarily saving time information in the graphic information, that the graphic is to be saved temporarily, so that the graphic is able to be invoked again when the presentation time of the graphic ends, and deleting the graphic from the register when determining, according to the temporarily saving time information, that the temporarily saving time of the graphic expires.

8. A terminal, comprising:

an acquiring unit, configured to acquire graphic information, wherein the graphic information carries a hyperlink and an identifier of the hyperlink;

a processing judging unit, configured to judge, according to the identifier of the hyperlink that is acquired by the acquiring unit, whether the hyperlink has been processed;

a requesting unit, configured to acquire graphic from a network according to the hyperlink when the processing judging unit determines that the hyperlink has not been processed; and

a displaying unit, configured to present, according to the graphic information, the graphic acquired by the requesting unit.

9. The terminal according to claim 8, wherein the terminal further comprises a reading unit;

the reading unit is configured to acquire graphic corresponding to the hyperlink locally when the processing judging unit determines that the hyperlink has been processed; and

the displaying unit is further configured to present, according to the graphic information, the graphic acquired by the reading unit.

10. The terminal according to claim 8, wherein the graphic information further carries temporarily saving time information, and the terminal further comprises a register, a temporarily saving time determining unit and a deleting unit;

the register is configured to save the graphic when determining, according to the temporarily saving time information in the graphic information acquired by the acquiring unit, that the acquired graphic are to be saved temporarily, so that the graphic are able to be invoked again when the presentation time of the graphic ends;

the temporarily saving time determining unit is configured to determine, according to the temporarily saving time information, whether the temporarily saving time of the graphic expires; and

the deleting unit is configured to delete the graphic from the register when the temporarily saving time determining unit determines that the temporarily saving time of the graphic expires.

11. A network device, comprising a sending unit and a receiving unit, wherein:

the sending unit is configured to send graphic information to a terminal, wherein the graphic information carries a hyperlink and an identifier of the hyperlink so that the terminal judges, according to the identifier of the hyperlink, whether the hyperlink has been processed; and

the receiving unit is configured to send graphic to the terminal when receiving a request for the graphic from the terminal.

12. The network device according to claim 11, further comprising:

a saving unit, configured to saving the graphic information, the graphic information being in a standard file format;

wherein

the sending unit is further configured to extract the graphic information from the saving unit and send the extracted graphic information to the terminal.

13. A communication system, comprising a terminal and a network device, wherein:

the terminal is configured to acquire graphic information, wherein the graphic information carries a hyperlink and an identifier of the hyperlink;

judge, according to the identifier of the hyperlink, whether the hyperlink has been processed; and

when determining that the hyperlink has not been processed, acquire graphic from a network according to the hyperlink and present the acquired graphic according to the graphic information; and

the network device is configured to send the graphic information to the terminal, and when receiving a request for the graphic from the terminal, send the graphic to the terminal.

14. The communication system according to claim 13,

the terminal is further configured to acquire graphic corresponding to the hyperlink locally when determining, according to the identifier of the hyperlink, that the hyperlink has been processed, and present the acquired graphic according to the graphic information.

15. The communication system according to claim 13, wherein:

the terminal is further configured to determine a presentation position of the graphic according to presentation position information carried in the graphic information, and display the graphic at the presentation position.

16. The communication system according to claim 13, wherein:

the terminal is further configured to stop presenting the graphic when determining, according to presentation time information carried in the graphic information, that the presentation time of the graphic expires.

17. The communication system according to claim 16, wherein the graphic information further carries temporarily saving time information;

and
