Embodiment
Technical scheme provided by the invention is: in the process of program recording, specify the program segment that needs to remove to generate the program segment covert marks for the user, skip according to the program segment covert marks segment that these needs are removed in the process of playback program recording, the effect that the user sees is exactly that this segment has been removed.
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
At first the technical scheme that the embodiment of the present invention provides needs the adlink of specifying needs to remove to the user, generates and adds the segment covert marks.
For the effect that makes the removal program segment that technical solution of the present invention provides the same with the stream file cutting, not only need to hide all program segment of mark in playing process, also need the update playing positional information, namely the position that obtains of user is the position (deduct all segment covert marks length after position) after segment is hidden.Position after segment is hidden is called relative position, and the position that the user obtains is all relative position; Do not consider that when fragment is hidden, the position in stream file is called the absolute position, the play position that obtains from playing module and the position of segment covert marks record are all the absolute positions, the description that concrete transfer process sees below.
Specifically, the product process of segment covert marks specifically comprises following step as shown in Figure 1:
1, the position of user's given ad segment, the i.e. starting position of given ad segment and end position (being relative position);
2, position conversion is converted to the absolute position with the relative position of user's appointment;
3, generate a segment covert marks according to the absolute position after conversion, this tag content has comprised the starting position of segment and the length of segment;
4, add new segment covert marks the list of to segment covert marks;
5, preserve the list of segment covert marks.
The corresponding segment covert marks list of each stream file, the list of segment covert marks is stored in permanent storage appliance jointly with corresponding stream file.
Wherein, for efficient segment covert marks bookkeeping, when the new segment covert marks of each interpolation enters list, all must must guarantee the list of segment covert marks in order and zero lap (when the scope of two segment covert marks has covering, being called two segment covert marks overlapping).
The idiographic flow that adds the segment covert marks list of to segment covert marks specifically comprises the steps: as shown in Figure 2
1, first segment covert marks that obtains the list of segment covert marks is current mark;
2, for after guaranteeing that new segment covert marks inserts, list is still arranged according to the starting position ascending order of mark, so need to find the starting position greater than first mark of new mark starting position, whether the starting position that judges current mark is greater than the starting position of new mark, if not, turn step 3, otherwise turn step 5;
3, current the marking whether of judgement is last mark of list, if not, turns step 4, otherwise turns step 6;
4, continue to obtain next mark as current mark from list, turn step 2;
If the starting position of 5 current marks is greater than the starting position of new mark, current mark be the list starting position greater than first mark of new mark starting position, so new mark is inserted the front of current mark, turn step 7;
6, list traversal is completed and is not found the starting position greater than the mark of new mark starting position, newly is labeled as the mark of starting position maximum, directly adds the list end to and gets final product;
7, judge that current mark end position whether less than new mark end position, if so, turns step 8, otherwise turns step 6;
8, current mark and new mark are merged into new mark, namely delete current mark;
Because list is according to the ascending sort of starting position, and the current back that is marked at new mark, thereby the starting position of current mark is necessarily greater than new mark starting position, so, if the end position of current mark during less than new mark end position (because the user can only obtain relative position, thereby the situation that current mark covers new mark end position can not appear), current mark is certain and new mark is overlapped;
9, current the marking whether of judgement is last mark in list, if not, turns step 10, otherwise turns step 6;
If 10 current marks are not the last marks in list, continue to obtain next mark as current mark from list, turn step 7;
After specifying the hiding adlink generation segment covert marks of needs and add in the list of segment covert marks according to the user, the a certain segment of inquiry that can also be from the list of segment covert marks, because the list of segment covert marks is according to ascending sort, and be non-overlapping, so the inquiry to assigned address is just very convenient and quick, idiographic flow as shown in Figure 3:
1, first segment covert marks that obtains the list of segment covert marks is current mark.
2, whether the starting position that judges the present pieces covert marks if so, turns step 3 greater than assigned address, otherwise turns step 5;
3, current the marking whether of judgement if so, turns step 7, otherwise turns step 4 into last mark of segment covert marks list
If 4 current marks are not the last marks in list, continue to obtain next mark as current mark from list, turn step 2;
5, judge that present pieces covert marks end position whether greater than assigned address, if so, turns step 6, otherwise turns step 7;
6, successful inquiring is returned to the present pieces covert marks;
7, inquire about unsuccessfully.
After specifying the hiding adlink generation segment covert marks of needs and add in the list of segment covert marks according to the user, when the user needs the playback recorded file, system will hide the segment of user's appointment automatically according to the list of segment covert marks, as adlink, these segments will be skipped when playing automatically, idiographic flow comprises the steps: as shown in Figure 4
1, play in the recorded file process, obtain current play position from the set-top box playing module in real time;
2, according to the list of current play position inquiry segment covert marks, see whether exist certain segment covert marks to cover current play position, if having, to turn step 3, otherwise turn step 1;
The program segment (being the advertising programme segment of user's appointment) of the segment covert marks institute mark of 3, automatically hiding that inquiry obtains;
4, obtain current broadcasting speed and preservation;
5, judge that current broadcasting speed whether greater than 0, if so, turns step 6, otherwise turn step 7;
The purpose of this step is that the current broadcast of judgement is to be to putting, if along putting, jump backward, if put upside down, jump forward, skipping adlink corresponding to segment covert marks along releasing;
6, jump to segment covert marks end position, and current broadcasting speed be set to the to jump speed of front preservation;
7, jump to segment covert marks starting position, and current broadcasting speed be set to the to jump speed of front preservation;
For the effect that makes the removal program segment that technical solution of the present invention provides the same with the stream file cutting, not only need to hide all program segment of mark in playing process, also need the update playing positional information, namely the position that obtains of user is the position (deduct all segment covert marks length after position) after segment is hidden.Do not consider that when fragment is hidden, the position in stream file is called the absolute position, the play position that obtains from playing module and the position of segment covert marks record are all the absolute positions.The absolute position deducts the length that is positioned at all the segment covert marks before this position, and what obtain is exactly relative position; And relative position adds the length that is positioned at all the segment covert marks before this position, and what obtain is exactly the absolute position.
The flow process that the absolute position is converted to relative position comprises following step as shown in Figure 5:
1, compose initial value for specifying the absolute position to relative position;
2, obtain first segment covert marks of segment covert marks list, as the present pieces covert marks;
Whether the end position that 3, judges the present pieces covert marks if so, turns step 4, otherwise turns step 5 less than specifying the absolute position;
4, relative position deducts the program fragment length of present pieces covert marks institute mark;
5, judge that whether the present pieces covert marks is last mark of segment covert marks list, if so, turns step 7, otherwise turns step 6;
6, continuously obtain next mark as the present pieces covert marks from list, turn step 3;
7, return to the relative position that clearing obtain.
The flow process that relative position is converted to the absolute position specifically comprises following step as shown in Figure 6:
1, compose initial value for specifying relative position to the absolute position;
2, first segment covert marks that obtains the list of segment covert marks is the present pieces covert marks;
Whether the starting position that 3, judges the present pieces covert marks if so, turns step 7, otherwise turns step 4 greater than specifying the absolute position;
4, the absolute position adds the program fragment length of present pieces covert marks institute mark;
5, judge that whether the present pieces covert marks is last segment covert marks of segment covert marks list, if so, turns step 7, otherwise turns step 6;
6, obtain next segment covert marks as current mark from list;
7, return to the absolute position that clearing obtain.
In the embodiment of the present invention, program segment for the needs removal, adlink in the program recording describes as example, during practical application technical scheme provided by the invention, be not limited to adlink, other users do not want that the program segment of watching can adopt method provided by the invention to remove equally, and this does not give unnecessary details.
