Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is further elaborated.
In order to ensure that the program before the current point in time can be recorded, on video equipment, set up a buffering area in advance.The spatial cache size of this buffering area can wish that the time of the recalling length of institute's any buffered program determines according to the user.When the video equipment broadcast items, the program of current broadcast carried out mould/number conversion after, be buffered in the set buffering area according to the mode of first in first out.
If the current mode broadcast items with digital signal of video equipment, then the present invention does not need the program of current broadcast is carried out mould/number conversion, and directly the program of the current broadcast of the video equipment mode according to first in first out is buffered in the set buffering area.
When the user will record the program before the current time, can from buffering area, obtain the program before the current time and store in addition on the storage medium of user's appointment, this storage medium is a storage medium that set in advance, non-volatile.
Because buffering area is the program that broadcasts with the real-time buffer memory video equipment of the mode of first in first out, so wait until when the spatial cache of buffering area takes the just program deletion of buffer memory at first.The mode of obtaining the program before the current time and store in addition on the storage medium from buffering area has two kinds.First kind of mode: at buffering area time started point and concluding time point are set, will put the time started and the concluding time put between the program storage of institute's buffer memory to storage medium.The second way: the time started point only is set at buffering area, and the concluding time point is not set, the program that then stores on the storage medium is the program of buffering area institute buffer memory between time started point and the current point in time, As time goes on this current time point is passed, therefore, storage medium will constantly obtain and store the program that the current point in time video equipment broadcasts from buffering area, up to receive stop record command till.
Below lift specific embodiment explanation the present invention.
Method provided by the invention is at first set up buffering area B on the hard disk of video equipment or memory, the P point is the current point in time of buffering area B, the time started of buffering area B point just, and the L point is the concluding time point of buffering area B.
Secondly that method provided by the invention is broadcasted video equipment and through the program D of D/A switch or program D that video equipment is broadcasted with digital signaling, according to the mode real-time storage of first in first out in buffering area.Program D begins storage from the P point, and spreads to the L point gradually.When the program D of storage arrives the L point, Cun Chu program D at first, just arriving the program D that L orders at first will be dropped.
Method provided by the invention is at last in the time will storing the program D among the buffering area B in addition, at buffering area B two pointers are set: pointer S and pointer E, pointer S indication is deposited time started point in the memory in addition with the program among the buffering area B, and pointer E indication is deposited concluding time point in the memory in addition with the program among the buffering area B.Pointer S and pointer E can only move on the program D among the buffering area B.
When from buffering area B, obtaining the program before the current time and storing on the storage medium in addition, can adopt two kinds of different modes.
First kind of mode, the closed interval storage mode: according to user's order, difference moving hand S and pointer E on the program D of buffering area B make pointer S point to the time started point, and pointer E points to the concluding time point.Usually, the time of the concluding time point that points to than pointer E all the time of the time started point that points to of pointer S in advance.Pointer E can overlap with the P point in the buffering area.The program D of buffering area institute buffer memory between the concluding time that the time started puts and pointer E the points to point of pointer S sensing is existed on the storage medium in addition.The schematic diagram of this closed interval storage mode on the time coordinate axle as shown in Figure 3.
Fig. 4 records the method flow diagram of former program of current time for the present invention adopts the closed interval storage mode, and its concrete steps are:
Step 400, in the hard disk of video equipment or memory, set up buffering area B;
Step 401, pointer S and pointer E are set on buffering area B;
Step 402, the buffering area B that is set up adopt that the mode of first in first out is broadcasted video equipment and carry out real-time buffer memory through the program D after mould/number conversion;
If video equipment is the mode broadcast items D with digital signal, then program D does not need to carry out mould/number conversion and just can directly carry out real-time buffer memory;
Step 403, buffering area B receive the order of recording former program of current time that the user sends, and the time period of wanting program recording is to some extent carried in this order;
Step 404, buffering area B want the time period of program recording that pointer S sensing is set respectively on the program D of buffering area B buffer memory according to this and want the time started point of program recording and the concluding time point that program recording is wanted in pointer E sensing;
Step 405, buffering area B judge whether concluding time point that time started point that pointer S points to and pointer E point to satisfies the rule that time of the concluding time point that time started point that pointer S points to points to than pointer E all the time shifts to an earlier date, if, execution in step 406; Otherwise, execution in step 408;
Step 406, buffering area B deposit the program D of institute's buffer memory between the concluding time that the time started puts and pointer E the points to point of pointer S sensing on the storage medium in addition;
Step 407, buffering area B promptly belong to the P point of buffering area B with pointer S and pointer E playback, finish;
Step 408, buffering area B send wrong indication, finish.
When recording before the current time program by the closed interval storage mode, also can distinguish pointer S and pointer E, as long as the program D of institute's buffer memory between the time point of two pointed is deposited on the storage medium in addition.Wherein, in when storage,, put programs stored D as the concluding time with time point from the nearest pointed of P point with from the time point of P point pointed farthest time point to start with.Like this, just can omit that step 405 is described have been judged.
The second way, one end open interval storage mode: according to user command, pointer S only is set on the program D of buffering area B buffer memory points to the time started point, the program D of institute's buffer memory is stored in the storage medium between time started point that S is pointed to and the P point among the buffering area B.Because the point of the P among the buffering area B is the current time, so stopping before the unloading order that buffering area B does not receive that the user sends, storage medium is the program D of the current institute of the P point buffer memory of memory buffer B ceaselessly.The schematic diagram of a this end open interval storage mode on the time coordinate axle as shown in Figure 5.
Fig. 6 records the method flow diagram of former program of current time for the present invention adopts an end open interval storage mode, and its concrete steps are:
If video equipment is the mode broadcast items D with digital signal, then program D does not need to carry out mould/number conversion and just can directly carry out real-time buffer memory;
Among time started point that step 605, buffering area B are pointed to pointer S and the buffering area B between the P point program D of institute's buffer memory store on the storage medium;
Step 606, buffering area B judge whether to receive that the user sends stops the unloading order, if, execution in step 607; Otherwise, re-execute step 605;
Buffering area B provided by the invention also can be the buffering area with annular data store organisation, as shown in Figure 7.L point among the buffering area B is fixed, and As time goes on the P point also carries out moving counterclockwise or clockwise, thereby buffering area is buffered in the program D that video equipment broadcasts among the buffering area B in real time.Under initial condition, P point and L point overlap, when the P point after buffering area B has moved a week, when overlapping with the L point again, show that the memory space of buffering area B is taken by program D.If continue the program D that the buffer memory video equipment broadcasts, promptly continuing will mobile P point, then according to the mode of first in first out the program D of the current broadcast of video equipment is covered the program D that has been stored among the buffering area B.
Method provided by the invention can be recorded the program before the current time, thereby make the user can not miss the program that does not have prior pre-recording, has greatly expanded the degree of freedom that the user watches TV programme.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being made within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
