displaying the upgrade software description information and upgrade prompt information to a user if local software is determined to be upgraded according to the upgrade software description information; and

obtaining an upgrade software mirror in the upgrade data stream, and updating the local software according to the upgrade software mirror after the user determines to update software.

2. The method according to claim 1, wherein the obtaining the DSI table in the upgrade data stream according to the location information of the upgrade data stream that is carried in the upgrade notification message comprises:

obtaining a transport stream packet in the upgrade data stream according to the location information of the upgrade data stream that is carried in the upgrade notification message; and

restoring the transport stream packet to obtain the DSI table that is comprised in a data segment section.

3. The method according to claim 2, wherein the restoring the transport stream packet to obtain the DSI table comprises:

restoring the transport stream packet to obtain the data segment section; and

finding the DSI table according to a table identifier table_id and a DSI information identifier message_id that are in the data segment section.

4. The method according to claim 1, wherein the displaying the upgrade software description information and the upgrade prompt information to a user comprises:

comparing the upgrade software description information with local machine version information to determine whether to upgrade the local software; and

if the local software is determined to be upgraded, displaying the upgrade software description information and the upgrade prompt information to the user.

5. The method according to claim 1, wherein the obtaining the upgrade software mirror in the upgrade data stream, and updating the local software according to the upgrade software mirror after the user determines to upgrade software comprises:

after the user determines to upgrade the software, obtaining a download information indication DII and a download data block (DDB) that are in the upgrade data stream;

obtaining the upgrade software mirror according to the DDB, and performing an integrity check on the upgrade software mirror; and

updating the local software by using the upgrade software mirror that passes the integrity check.

6. A software upgrade method, wherein the method is applied to a software upgrade of a digital television terminal and comprises:

adding upgrade software description information to a download server indication (DSI) table of a digital storage media command and control (DSM-CC);

obtaining an upgrade data stream according to the DSI table and an upgrade software mirror corresponding to upgrade software; and

sending an upgrade notification message to the digital television terminal, wherein the upgrade notification message carries location information of the upgrade data stream, and the upgrade notification message is used to determine whether to download the upgrade data stream so as to upgrade local software.

7. The method according to claim 6, wherein the adding upgrade software description information to the DSI table of the DSM-CC comprises:

adding the upgrade software description information to a private field of the DSI table.

8. The method according to claim 6, wherein the obtaining the upgrade data stream according to the DSI table and the upgrade software mirror corresponding to upgrade software comprises:

encapsulating the upgrade software mirror by using the DSM-CC; and

loading the encapsulated upgrade software mirror and the DSI table into a data segment section to obtain the upgrade data stream, wherein the upgrade data stream comprises at least one transport stream packet.

9-16. -16. (canceled)

17. A digital television terminal, comprising:
