After reading the detailed description of the utility model execution mode in conjunction with the accompanying drawings, other characteristics of the present utility model and advantage will become clearer.
Description of drawings
Fig. 1 is the theory diagram of a kind of embodiment of the television set internal circuit that proposes of the utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
What the recording function of existing television set was realized is to record the current programme content of watching, and the definition of recording function while seeing truly is to realize when the user watches a certain signal source passage program to this passage program or from the real-time recording of other signal source passage program, and then reaches and watch the purpose separate with program recording.
The television set that the utility model proposed is by setting up audio/video coding/decoding unit on original television set inner decoding plate, after carrying out encoding process to the current video frequency program of watching of user or from the audio/video program of other signal source passage, export memory device to and store, thereby realized the recording function while seeing of tv product.
Embodiment one, referring to shown in Figure 1, in the tv product of present embodiment, be provided with the multiple signals source channels, for the user can also be recorded the TV programme of other channel when appreciating a certain channel TV program, be provided with the two-way high frequency tuner circuit in described multiple signals source channels: tuner 1, tuner 2 can receive the radiofrequency signal of two channels at one time.Meanwhile, in order to make TV set reception and broadcast function from the audio, video data of other signal source, in described multiple signals source channels, also be provided with one the tunnel or multipath signal source interface: signal source 1 ..., signal source N (N is a natural number), all can be contained and the signal source that useful signal shows to television set can be imported, such as AV interface, HDMI interface, YPbPr interface, DVI interface or the like, when realizing television set or switch receiving function to radiofrequency signal and other vision signal.
Certainly, also one road high frequency tuner circuit can only be set in described multiple signals source channels, the user can select to record the audio, video data from other signal source when watching the TV RF program like this; Perhaps the user can select the multi-medium data of record tv radio frequency program or other signal source when the audio, video data of appreciating from signal source 1 or signal source N passage.Present embodiment does not specifically limit this.
Described multiple signals source channels connects one to one with the multi-channel input of a multichannel switching switch circuit respectively, under the effect of described multichannel switching switch circuit, select wherein one the tunnel or two paths of signals source channels data be linked in the television set; Its two-way output one tunnel connects the video signal input terminal of the Video processing/coding display unit on the television set decoding deck, and another road connects the audio-video signal input of audio/video coding/decoding unit.The control end of described multichannel switching switch circuit connects described Video processing/coding display unit, receives the gating signal of its output, and then specifically determines gating which or which two paths of signals source channels.The broadcast that described gating signal is selected according to the user by Video processing/coding display unit and record channel instruction and specifically generate is correctly switched by customer requirements with the control its switch circuit.
Described Video processing/coding display unit connects audio/video coding/decoding unit by many signal line, and the agreement of working out by inside is carried out communication between the two, and described holding wire can be I
2C bus, universal serial bus or GPIO holding wire or the like.On the one hand, Video processing/coding display unit is when receiving the record command that the user sends, and the output control signal starts audio/video coding/decoding unit and receives audio, video data.Described audio, video data can be by the radiofrequency signal of multichannel switching switch circuit gating output or from the audio, video data of other signal source, also or by Video processing/coding display unit anticipates the video data that export the back; Described video data both can be the program data of the current broadcast of television set, can also be other video data.Described audio/video coding/decoding unit converts the signal format that memory device can receive to after the audio, video data that receives is encoded, and transfers to memory device by memory interface.Described memory device can be the storage chip of television set inside, also can be the Stand Alone Memory that is placed on television set.When described memory device is the storage chip of television set inside, described memory interface promptly refers to data, address and the control signal terminal of audio/video coding/decoding unit, be connected with the respective pin of storage chip is corresponding by data signal line, address signal line and control signal wire, realize the transmission storage of audio, video data.And when described memory device was selected external Stand Alone Memory, described memory interface referred to independently be arranged on the communication interface on the tv shell; At this moment, audio/video coding/decoding unit is connected with the respective pin of described memory interface is corresponding with control signal wire by data signal line, address signal line, and then, preserve with the transmission that realizes audio, video data by the outside memory of described memory interface connection.On the other hand, when the user selects to play the video frequency program of having recorded, Video processing/coding display unit sends and controls signal to described audio/video coding/decoding unit, and then control it and read the audio, video data of preserving in the memory device, and after it is carried out decoding processing, convert signal format that Video processing/the coding display unit can receive to and pass to Video processing/coding display unit and handle, and then the control television display screen is play recorded program.
Considering that audio, video data by the input of some signal source passages can exist does not meet described Video processing/coding display unit and the audio/video coding/decoding unit call format to input signal, therefore, in the television set of present embodiment, can also be provided with one the tunnel or the two-way audio/video decoder, so that the audio-video signal that inserts is carried out decoding processing in advance.The two-way audio/video decoder preferably is set, and one the tunnel is connected between the video signal input terminal of the first via output of multichannel switching switch circuit and Video processing/coding display unit; Another road is connected between the audio-video signal input of the second road output of multichannel switching switch circuit and audio/video coding/decoding unit.The control end of described audio/video decoder receives from the control signal that Video processing/the coding display unit sends, and whether the audio-video signal of importing is carried out decoding processing to control it.
Wherein, the audio/video decoder that is connected with the first via output of switching switch circuit is after carrying out decoding processing to the audio, video data that receives, the audio signal that generates connects the audio processing unit of television set by its audio signal output end, and then drives the sound accompaniment of loud speaker output program.
Among Fig. 1, UI is a user interface, can comprise USB interface, parallel port or serial ports or the like, to realize the interconnected communication of television set and external equipment.
In the present embodiment, described multichannel switching switch circuit can adopt a multiselect two integrated switch chips to realize, also or by the establishment of variable connector element forms, and present embodiment does not specifically limit this.
Certainly; the above only is a kind of preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
