Get back to Fig. 2, in picture frame capture systems 2000 according to a second embodiment of the present invention, Subscriber Interface Module SIM 2230 is pressed specific keys such as user, is clicked the mouse, touch display screen etc. time, the picture frame receiving user's input obtains request, and determine current time, namely receive the time that picture frame obtains request.Time calibration, module 2220 was according to the time difference T between user terminal 2200 and TV program player 2100
dwith request transmission time T
s, determine the request transmission time T on the time reference of TV program player
e=T
s-T
d, the time of the picture frame that namely will extract.Then, time calibration, module 2220 was by determined request transmission time T
esend to communication module 2210, communication module 2210 sends the request of catching picture frame subsequently to TV program player 2100 by network, and this request comprises the determined request transmission time T of instruction
einformation.The communication module 2110 receiving request forwards this request to picture frame extraction module 2120.Extract the picture frame cache module 2130 of the picture frame of the program that picture frame extraction module 2120 is play from buffer memory and the request transmission time T that comprises in request
ecorresponding picture frame.The analog or digital decoding data of signal decoding module 2140 pairs of TV programme, and decoded data is delayed be buffered in picture frame cache module 2130 with the form of picture frame.Then, extracted picture frame is sent to user terminal 1200 by communication module 2110.User terminal 1200 can show the picture frame received on display module 2240.
According to embodiments of the invention, by setup times calibration module in picture frame capture systems, no matter on a television receiver or on the subscriber terminal standing time calibration module, the time migration between television receiver and user terminal can be eliminated, thus improve the precision of catching the picture frame that user wants.
According to embodiments of the invention, module can perform primary calibration process or perform calibration process termly, otherwise when starting time calibration, then stored the determined time difference, used it in later operation.
According in the picture frame capture systems of the present invention first and second embodiment, user, by Subscriber Interface Module SIM input request, can obtain in the TV programme play in TV program player, picture frame when user presses request.
According to an example, the request of Subscriber Interface Module SIM input can be the orders of single screenshotss, namely catches the request of current image frame, or screenshotss order continuously, namely catches the request of continuous multiple picture frame.Such as, user can at time T
0press the command key on Subscriber Interface Module SIM, trigger and start to catch picture frame, and at time T
ndischarge this button, terminate catching of picture frame.In this example, Subscriber Interface Module SIM using the initial time of user's input request and end time as the time receiving request.Like this, in the request that TV program player receives, the information of request transmission time is indicated to indicate a period of time, instead of a time point.In this example, as shown in Figure 1, picture frame extraction module 1130 can comprise extraction picture frame determination module 1132, is configured to the length determining this time period.If the length of this time period is less than predetermined threshold, and determines that the picture frame that will extract is picture frame corresponding with the initial time of this time period in the picture frame of buffer memory.And if the length of this time period is not less than described predetermined threshold, then determine that the picture frame that will extract comprises in the picture frame of buffer memory from the picture frame corresponding with the initial time of this time period to multiple picture frames of the picture frame corresponding with the end time of this time period.
Fig. 5 shows the schematic diagram of the operation of the picture frame that will extract according to the determination of the embodiment of the present invention.As shown in Figure 5, user at time T
0to push button and at time T
nwhen discharging this button, assuming that predetermined threshold is 800ms.If T
n-T
0<800ms, then the picture frame that will extract is frame 0.If T
n-T
0>=800ms, then the picture frame that will extract comprises from frame 0 to the N+1 of frame N picture frame.
According to embodiments of the invention, can operate when there is multiple TV program player.Fig. 6 shows the schematic diagram that there is the situation of multiple TV program player according to the embodiment of the present invention.As shown in Figure 6, assuming that there is N number of TV program player.In this embodiment, the communication module of user terminal broadcast search request when needed.Feedback is comprised the response message of its identification information by the TV program player receiving searching request, and this identification information can be the information such as information, model of the IP address of such as TV program player, identifier id, sequence number, manufacturer.The user terminal receiving response message can identify each TV program player, and obtains the information of asking the TV program player comprised as target acquisition at the picture frame of follow-up transmission.Correspondingly, receive picture frame catch request TV program player will identify request in instruction TV program player, if self, then carries out image frame-grab operation, if not, then ignore this request.
Fig. 7 shows another schematic diagram that there is the situation of multiple TV program player according to the embodiment of the present invention.As shown in Figure 7, assuming that there is N number of TV program player.In this embodiment, TV program player termly or when needed, such as, when starting shooting, himself information of broadcast identification, the information, model etc. of the IP address of such as TV program player, identifier id, sequence number, manufacturer.The user terminal receiving identification information can identify each TV program player, and obtains the information of asking the TV program player comprised as target acquisition at the picture frame of follow-up transmission.Correspondingly, receive picture frame catch request TV program player will identify request in instruction TV program player, if self, then carries out image frame-grab operation, if not, then ignore this request.When user remains that user terminal is started shooting, utilize this embodiment, user terminal does not need frequent broadcast search request to search for the TV program player that can communicate with it.Such as, TV program player sends its identification information, to notify its existence to user terminal when starting shooting.Like this, the waste of resource can be reduced.
Fig. 8 shows the flow chart of the television program image frame-grab method 800 according to the embodiment of the present invention.As shown in Figure 8, when TV program player plays TV programme, the method starts.In step S810, multiple picture frames of the TV programme that buffer memory is play.Next in step S820, receive the request of catching picture frame from user terminal, described request comprises the information of instruction request transmission time.In step S830, according to the information of the instruction request transmission time comprised in the time difference between described television program image frame-grab equipment and described external equipment and described request, determine the time of the picture frame that will extract.Finally, in step S840, from multiple picture frames of buffer memory, extract the picture frame corresponding with the time of the determined picture frame that will extract.
Like this, the picture frame play when accurately can be captured in the request sending and catch picture frame.Caught picture frame can be returned the user terminal of the request of sending, to show on the subscriber terminal.
According in the method for this embodiment, the TV program player performing the method can perform the calibration process with user terminal in advance, to determine and to preserve time difference of TV program player and user terminal, for follow-up use.
