When the recording module (10) starts recording the TV program, the user can define the slice header when playing the head. For example, the user can input the start and end signals of the slice header by the function button on the (not shown) of the set-top box, so that the set-top box 1G is playing during the time period of the start signal and the end signal. The title. At this time, the user record module 102 sequentially records the special character corresponding to each frame of each picture group in the user slice header. Specifically, the signal that the recording module 102 picks up at the beginning of the recording process is received from the subsequently received television program, the number of the received form number 丨 page 8 / total 23 s a 1 1002004579-0 201233174 [ 0020] Ο 讯 The frame starts to record the type of each dragon and the number of transport streams it includes until the end of the slice is received. Then, the recording module 1〇2 combines the type of each frame and the number of transport streams included therein into the feature identification word of each frame. FIG. 3 is a schematic diagram of generating a feature identification word on the set-top box of FIG. As shown in Fig. 10, in the present embodiment, a special number is used to indicate the type of the frame. In order to reduce the space occupied by the special number, the hexadecimal digit of eight bits is preferred. For example, 〇χ1〇〇〇〇〇〇〇 indicates the frame, and 0x00000000 indicates that the frame ’0χ20__ indicates the frame. In other implementations, other numbers may be used to indicate the type of frame ’ only need to be preset. The number of transmissions is also preferentially represented by the hexadecimal digits of the eight digits. For example, if the number of transmission streams of the frame of the first picture group is counted as 1128, it is available. 468 said. Then, you can use the OR operation to combine the frame type with the number of transport streams. For example, the feature identifier of the first frame group can be used to express the frame type I frame and the number of the stream 0x00000468 in the frame. Or the operation results, that is, 〇χ1〇〇〇〇468 [0022] 100102574 The matching module 104 determines whether the number of transmission streams of the frame in the subsequently received television program is the same as the first feature recorded. Identification word matches. If the I frame in the subsequently received television program matches the recorded first feature identification word, it indicates that the I signal may be the beginning of the next header. At this time, the matching module 104 starts to sequentially determine whether the type of the frame and the number of transport streams after the I frame match the recorded feature identifier. The following describes in detail how the matching module 1 〇4 sequentially determines the type of the frame and the number of transmission streams after the frame of the frame number Α0101, page 9/23 pages 1002004579-0 201233174, in conjunction with FIG. Recorded feature identification word - match. First, the matching module 104 receives the second frame, first determines its type, and counts the number of transport streams, and then combines the frame type with the number of transport streams, and determines whether the combined result and the graph are combined. The second feature identification word shown in 3 is the same. If the combined result is not the same as the second feature recognition word, it means that the title is being played, so the comparison is stopped and the next I frame is continued. [0023] If the combined result is the same as the second feature identification word, it indicates that the second frame matches the second feature identification word. Then, the matching module 104 determines whether the received third frame matches the third feature identification word, if it matches, determines whether the received fourth frame matches the fourth feature identification word, and so on.

The number of transmissions of the I frame and the first feature identification recorded in step S406, the matching module 1〇4 determines the comparison! Whether the frame transmission matches the recorded first feature identification word. If the 1 frame of the pair does not match the recorded first feature identifier, indicating that 1 is not the title of the slice, then in step _, the matching module ι〇4 continues, and the I frame of the subsequent record is transmitted. The number of rounds (four) and the number of identification characters recorded. ^ The aligned I A frame matches the recorded first feature identification word, indicating that the playback may be the title of the slice at this time, then in step S408, the matching module (10) determines that the matching is in the match! Whether the type of frame after the frame and the number of transport streams match the recorded feature identifier_. If there is a feature identifier that does not match the corresponding frame, and the system is not the slice header, then in step S404, the matching module 1〇4 continues to compare the number of the relay streams of the subsequently received frame. The first feature identifier of the record. Form No. A0101 « ----1002004579-0 201233174 [0029] If the frame after the matching I frame and the recorded feature recognition word can match - it means that the title is played at this time, then In step S41 0, the marking module 106 tags the matching I frame in the recorded television program. [0030] In step S412, the matching module 104 determines whether the program is recorded. If not, the steps S404 to S410 are repeatedly performed to continue marking the next title. [0031] FIG. 5 is a detailed flowchart of an embodiment of the feature identification word of the frame in the slice header in step S400 of FIG. In step S500, the recording module 102 receives the signal of the start of the slice header during the recording process. In step S502, the recording module 102 sequentially records the type of each frame and the number of transport streams included therein from the first I frame in the subsequently received television program until the end of the slice is received in step S504. signal of. In step S506, the recording module 102 synthesizes the type of each frame and the number of transport streams it includes into the feature identification word of each frame. [0032] FIG. 6 is a flow chart showing an embodiment of a recorded television program being played by the set-top box 10 of the present invention. In step S600, the tag module 106 records the frame serial number corresponding to each tag. In step S602, the play module 108 displays the recorded program segments for the user to select. Each of the tags corresponds to a program segment, and each segment includes a title, a program segment, and an advertisement. In step S604, the play module 108 plays the program segment selected by the user. During the playback, if an advertisement is encountered, the user can send a signal to skip the advertisement by using the function key on the remote controller.
