when determining that the hyperlink has been processed, acquiring a graphic from a local register corresponding to the hyperlink, and displaying the graphic at a presentation position according to presentation position information; and

stopping displaying the graphic when determined a time for displaying the graphic expires according to the presentation time information.

2. The method according to claim 1 , wherein the graphic information further carries temporarily saving time information the method further comprising:

when determining that the hyperlink has not been processed, acquiring a graphic from a network according to the hyperlink, and saving the graphic in the local register when determined the graphic needs to be saved temporarily according to the temporarily saving time information.

3. 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.

4. 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 the identifier recording table has an identifier that is the same as the identifier of the hyperlink;

if the 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 the 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.

5. A terminal, comprising:

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

a processing judging unit, configured to judge, according to the identifier of the hyperlink and an identifier recording table, whether the hyperlink has been processed, wherein the identifier recording table is used for recording identifiers of hyperlinks that have been processed and identifiers of hyperlinks that are being processed;

a reading unit, configured to acquire graphic from a local register corresponding to the hyperlink when the processing judging unit determines that the hyperlink has been processed; and

a displaying unit, configured to display the graphic acquired by the reading unit at a presentation position, according to the presentation position information;

and stopping displaying the graphic when determined a time for displaying the graphic expires according to the presentation time information.

6. The terminal according to claim 5 , wherein the terminal further comprises a requesting unit;

the requesting unit is 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

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

7. The terminal according to claim 5 , 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 is to be saved temporarily, so that the graphic is 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.

8. 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, and further carries presentation position information and presentation time information;

judge, according to the identifier of the hyperlink and an identifier recording table, whether the hyperlink has been processed, wherein the identifier recording table is used for recording identifiers of hyperlinks that have been processed and identifiers of hyperlinks that are being processed; and

when determined that the hyperlink has not been processed, acquire graphic from a local register corresponding to the hyperlink and displaying the acquired graphic at a presentation position according to the presentation position information;

stopping displaying the graphic when determined a time for displaying the graphic expires according to the presentation time 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.

9. The communication system according to claim 8 ,

the terminal is further configured to acquire graphic from a network according to the hyperlink when determining, according to the identifier of the hyperlink, that the hyperlink has not been processed, and present the acquired graphic according to the graphic information.
