Embodiment
In conjunction with shown in Figure 1.Digital TV set-top box 100 disclosed by the invention comprises: the signal receiving module 110 that is used for received television signal; Be used for carrying out the decoder 120 that audio decoder is handled and video decode is handled to receiving TV signal; The digital audio and video signals after being used for output decoder and handling and the output module 130 of digital video signal; The video pictures intercepting control module 140 that is used on schedule at interval the digital video signal intercepting frame of video after the decoding processing; The buffer 150 that is used for temporary described frame of video; Be used for the triggering command sent according to the user and trigger and create picture and browse window, and control is shown in this picture with nearest in a buffer frame of video and browses the picture of window and browse window creation module 160; Be used for controlling the user is browsed the picture-storage controller 170 that frame of video that window selects converts user's picture selected form to and preserves image data from picture; Be used to store the memory 180 of described image data.
Wherein, according to the mode of received signal, digital TV set-top box 100 roughly comprises 2 classes: a class is the digital television signal that can receive wired/satellite/terrestrial broadcasting; Another kind of is to be used in the digital television program signal that is used in the IPTV system receive with the transmission of IP protocol mode.
If digital TV set-top box 100 is the digital television signals that can receive wired/satellite/terrestrial broadcasting, then aforementioned signal receiving module 110 comprises: be used for and will receive cable TV signal, wireless television signal or terrestrial broadcast television signal and be converted to the tuner of transport stream; Be used for transport stream is done the descrambling demultiplexing processor of scramble process and demultiplexing processing and output audio, video data.
If digital TV set-top box 100 is the digital television program signals that receive with the transmission of IP protocol mode, then aforementioned signal receiving module 110 comprises: be used to receive the IP packet receiver module with the IP digital television program packet of IP protocol mode transmission; The IP digital television program packet that is used for receiving is made the IP packet recombination module that reorganization is handled.
In addition, consider the standard variation of TV signal, the program of different systems has 25 frame/seconds or 30 frame/seconds, and in fact and need not that all frames carry out buffer memory in the logarithm word vision signal, and can be according to the predetermined time interval of the data-handling capacity and the default intercepting of the spatial cache size frame of video (being the picture that television image is play) of digital TV set-top box 100; And the parameter that this predetermined time interval can be revised as a user can be made an amendment according to actual needs by remote controller.
Certainly, can obtain the frame of video of preferable effect for guaranteeing the user, many sectional drawings frame of video as much as possible in theory, this just requires the memory space of buffer 150 enough big.
In addition, picture with intercepting has purposes widely for the convenience of the user, digital TV set-top box 100 can also be provided with coffret 190, this coffret 190 is USB interface, serial line interface or network interface etc., can easily the picture that intercepts be transferred to external equipment by this coffret 190.
In conjunction with shown in Figure 2, the present invention is described in further detail.Present embodiment may further comprise the steps:
Step S210, user pass through the digital TV set-top box received television signal, normal TV reception.
Step S220, at interval according to preset time, the digital video signal intercepting frame of video from the TV signal that step S210 plays in real time, and frame of video is temporarily stored in the buffer.
Whether step S230, digital TV set-top box judgement have the user to send by remote controller and be used to trigger control starts the triggering command that the user does the sectional drawing processing.Certainly, the setting in advance of this triggering command is made up by a specific keys on the remote controller or specific a plurality of cases and is produced.
Step S240, when receiving the triggering command that the user sends, trigger to create picture and browse window, and the control frame of video that will intercept recently is shown in this picture and browses window.
Step S250, be used for and come by the key up and down on the remote controller, make the different video frame that is kept in the buffer be shown in this picture and browse window.
Step S260, digital TV set-top box judge whether the user when the picture of browsing video frame, has the picture of choosing a wherein specific frame of video.
Step S270, when the user chooses the picture of a wherein specific frame of video, select to protect the form of picture by the user, digital TV set-top box converts the picture of this frame of video to user's picture selected form.
Step S280, image data is saved to the specific memory device.This memory can be passed to external equipment with the image data of preserving by USB interface, serial line interface or network interface, also the image data of preserving can be offered the user as start-up picture of digital TV set-top box or the like.
Step S290, if the user continues to select picture, then change step S250, if the user withdraws from the selection picture, then change step S210.
Hence one can see that, the present invention extracts the frame of video of current video stream and keeps in from the decoder of digital TV set-top box, and can eject picture according to user's triggering command and browse window, temporary frame of video is browsed window by picture show, the picture format preservation that provides the user to select specific video frame and select by the user.Therefore, the present invention has made things convenient for the digital TV set-top box user, for the user provides inexhaustible picture loading source, makes things convenient for the user to utilize the television video picture of intercepting to do various personalized customization successively.
