In the present embodiment, user freely defines the length of this predetermined amount of time as required.If the recorded program duration completed when receiving and obtaining instruction is less than the length of this predetermined amount of time, then only obtain the whole program file recorded.In another embodiment, the length of this predetermined amount of time is that system is predefined, and system can obtain corresponding scheduled time segment length automatically from recorded program.
Because programme signal can be a kind of multiplexing code stream containing Multiple components, contain the respective audio frequency of several programs, video and transmission data, therefore need that demodulation carried out to the current programme signal play multiplexing, it is resolved into successively the plurality of packets only comprising audio or video.When after this recording operation instruction of reception, to each package mark timestamp, generate this program recording file, and by this program recording file carry out buffer memory.As follows to the method for each package mark timestamp: receive a reference clock signal, the time wherein on reference clock is linear increment; When receive need each package mark timestamp time, timestamp is made zero, then along with the time on reference clock incrementally gives the package mark generated successively timestamp.For example, general each package comprises the packet header of 0x47 and the data of 187 bytes, adds the timestamp of 4 bytes before each package., then along with the time on reference clock incrementally to add before timestamp to the package generated successively in 4 bytes, successively timestamp mark is carried out to each package.
Please also refer to Fig. 4, for obtaining the flow chart of the program fragment of a predetermined amount of time in the embodiment of the present invention from this program recording file.
Step S40, determines that generation one obtains the moment of instruction, is the initial time obtaining program fragment.
Step S42, obtains scheduled time segment length.Scheduled time segment length wherein in this database is that user or system default pre-set in a database, can carry out dynamic conditioning.
Such as then user is stored in database by a user interface (UI) dynamic input scheduled time segment length and supplies to call, and obtains good Interactive Experience.
Step S44, according to obtaining the initial time of this program fragment, scheduled time segment length and this timestamp of each package in program recording file, copy corresponding program fragment from program recording file.
Such as when producing this acquisition instruction, suppose that program recording file size is 1 minute, and this predetermined amount of time is 20 seconds, so, the package being just the 40th second to the 60th second by the timestamp on program recording file copies and preserves.
In one embodiment, by at the copy to program fragment, store, playback (is play, suspend, put slowly), the different event state of program fragment is regarded in the action terminating (finish) as, system can detect these thing states and feed back to user, and such user can understand the process obtaining program fragment in time.When system receives again other operational order, can according to the thing state status detected, other operational order is recalled in time by recalling (callback) mechanism, so, system can not be interrupted by other event easily and jump out recording mode, ensures to carry out smoothly the execution of program fragment.With reference to figure 5, for recalling the flow chart of other operational order in the embodiment of the present invention.
Step S50, detects current event state status, detects the percentage situation that each state-event completes specifically.
Step S52, draws the state-event situation detected and selects for user over the display, such as progress bar, the mode of dialog box.
Step S54, the instruction sent after carrying out selection operation according to user judges whether to recall other operation, if result is yes, carries out step S56; If the result is negative, terminate recording mode, flow process terminates.
Step S56, recalls other operational order, and system proceeds each operation of recording mode.
Please refer to Fig. 6, for carrying out the schematic diagram of performance recording in the embodiment of the present invention to the dissimilar current program play.Specifically, Fig. 6 is that supposing the system is in recording mode, to dissimilar current playing program when, how to obtain the schematic diagram of predetermined amount of time program fragment.The mark that the mark that Duration is this predetermined amount of time, StartTime are the initial time of the program fragment (hereinafter referred to as obtaining program fragment) obtaining this predetermined amount of time, namely, the initial time of this predetermined amount of time, TriggerTime is the trigger instants obtaining program fragment, that is, the moment obtaining operational order is received.In the present embodiment, for the current program play be programme televised live, video program and when being in the video program of shifting state be described.
Enter a ground, as shown in Figure 6, when the current program play is programme televised live, system is recorded a video to this programme televised live, and while detect triggering signal, namely receives this acquisition instruction.When triggering signal being detected, determine the moment receiving this acquisition instruction, that is, the moment of the current broadcasting of this programme televised live, thus determine the initial time StartTime of this predetermined amount of time according to this moment and scheduled time segment length.Now, system obtains required program fragment from recorded program file, this recorded program file be under system is in recording mode, this programme televised live is played to the moment institute's recorded program file receiving this acquisition instruction.
When the current program play is video program, in such cases, owing to having saved this program in system, so the recording of the program of current broadcasting can not be carried out when video program is play, but only detect triggering signal.When triggering signal being detected, system determines initial time StartTime according to the moment and predetermined amount of time Duration that receive this acquisition instruction, and directly obtains the program fragment of corresponding time period from this video program.
Current just broadcast program be in time shifting state program time, time shifting state refer to time shift operation carried out to program.So-called time shift operation, after just referring to that user suspends viewing actual program a period of time, the program after the program times be suspended or the program before playback are watched in continuation.Playback and the recorded broadcast playback of the present invention of traditional time shift operation are different, traditional time shift operation playback be the whole file of recorded program, the program fragment seen can't be wanted as playback in the present invention, different in user operation, the scheme realized is not identical yet, recorded program file is just deleted, not as in the present invention preserved program fragment for user after time shift operation traditional in addition terminates.The scene supposed is, user is when watching programme televised live, can not continue for some reason to watch program, just suspend this programme televised live, but system is still recorded this programme televised live, after a while, when user wants to continue viewing program, just can continue viewing from the moment be suspended, or the splendid moment that playback is missed.When playback, systems axiol-ogy triggering signal, moment and predetermined amount of time Duration according to receiving this acquisition instruction determine initial time StartTime, and obtain the program fragment of correspondence from recorded program file.Because time shift operation can't stop the video recording to programme televised live, therefore video recording moment and playback moment middle meeting difference for some time.This program can also be video program, and operation principle is similar, does not add repeat at this.
