Television set intelligently storage of the present invention and back method comprise following key step:
A, input broadcast television signal
B, decoding
During work, the radio frequency decoder mainly is responsible for the radiofrequency signal of TV is become the AUDIO (audio frequency of standard, AUDIO1/AUDIO3) and VIDIO (video, VIDIO1/VIDIO3) picture signal (consulting Fig. 3), the output of a radio frequency decoder (AUDIO1 and VIDIO1) is directly inputted in the ON-OFF control circuit, and the output of ON-OFF control circuit is connected in the input of the VIDIO1 of television set and AUDIO1; In addition, the output of another radio frequency decoder is to be input to VIDIO encoder/AUDIO encoder, vision signal (VIDIO3) is imported through input terminal, through the SAA7113 code conversion is that digital signal outputs to digital signal processor (consulting Fig. 4) by VD0-VD7, makes data compression process for digital signal processor.
C, stored television signal
Programs stored signal if desired, flush bonding processor will the picture signal that compression is good preferentially be deposited in the storage device with audio frequency, when content is big then in the typing disk.Storage mode is the programme signal content stores for the previous period with current broadcast, if random asccess memory or flash memory then adopt the queue stores mode of " first in first out " (being that up-to-date picture covers the oldest picture), there is not the full and artificial problem of deleting of needs of memory.When promptly televising current content, the content of a period of time before having stored in advance in it.Cun Chu time period can be regulated arbitrarily in advance, and maximum length depends on the capacity and the compression ratio of memory.Digital signal processor in the empty frame must not have, if the speed of flush bonding processor is enough fast, can satisfies the Compress softwares of data and handle, and digital signal processor is omissible.
D, playback TV signal
If want to play out the content of having stored, then directly read the content of storage device the inside by microprocessor, or read data in the disk by flush bonding processor, then data are sent to digital signal processor, digital signal processor can carry out decompress(ion) with data, be sent to VIDIO decoder/AUDIO decoder with separating the data that press, digital signal is imported by VD0-VD7, is converted to vision signal (VIDIO2) through the SAA7121 decoding and outputs to switch selection control circuit (consulting Fig. 5) by lead-out terminal.ON-OFF control circuit select as required VIDIO1 still be VIDIO2 and AUDIO1 still be that AUDIO2 is on the VIDIO1 and AUDIO1 of television set; If think the data that playback is of short duration, under the situation that the flush bonding processor random asccess memory allows, directly carry out playback, and do not need to read disk with the data in the random asccess memory, certainly the data of playback are bigger, and that just needs the good data of storage of reading disk to carry out playback.
Television set intelligently of the present invention storage and playback system product comprise external and embedded two kinds, embedded then being built in the television set, and its decoder and microprocessor adopt decoder and the microprocessor in the television set under the conditions permit.
Encode/decode audio signal imput output circuit figure can consult Fig. 6, and digital signal processor circuit figure can consult Fig. 7, and the flush bonding processor circuit diagram can be consulted Fig. 9, and ON-OFF control circuit figure can consult Figure 12.
Television set is located at the VIDIO1 state, and the remote control of television set is selected to be actually and carried out in television set intelligently storage and playback system, does not have what difference with old video tape recorder.When television set intelligently storage and playback system are not in store status, video VIDIO1/VIDIO3 signal and audio A UDIO1/AUDIO3 signal all are synchronous all the time, two paths of signals is just the same, when needs are stored in progress program, the VIDIO1/AUDIO1 signal is than slow a period of time of VIDIO3/AUDIO3 signal, the VIDIO3 of this system of direct access and AUDIO3 output signal are just passable, and the length of storage just equals this section period; When the needs storage is different from the program of televising, a kind of method is to choose the back by channel selection to start storage, VIDIO3 and AUDIO3 were with locked after storage started, and it can not change along with the variation of VIDIO1 and AUDIO1, at this moment just can select other channel to see; Another kind of scheme is exactly the channel of pre-set storage and the time period of storage, and system will start storage system automatically to the time, adjusts the output signal of VIDIO3 and AUDIO3 automatically and stores according to the requirement that chooses in advance.
Present image stipulated time the last period when to sum up, the present invention can watch TV programme to the spectators content of (user's setting) is stored with digital form.When spectators found just to miss one section program, the content of that section just now that only will store in advance simply accessed playback again, and highlight can not miss.For example when playing with lottery the question and answer game program in the TV Festival, after spectators do not hear exercise question, want to send the question and answer game mode of just finding in the answer on the screen, or telephone number (note number, email address) disappears.Perhaps spectators have lost the chance of once getting Grand Prix like this.Perhaps after one section advertisement, realize that just spectators are very interested in this product, spectators want to understand the details of this product urgently, and spectators do not remember contact method, or manufacturer, spectators have to wait for appearance next time, but do not know next time when.Also have when spectators watch TV play, would like to know the actor name of playing certain role, and when playing cast, can't remember, have to stay sorry because of excessive velocities.Had the present invention just can help spectators to address these problems, spectators can stay the picture stop of needs on the screen, the information that needs of note storage at leisure, perhaps aftertaste exciting part just now at leisure.
And because digitlization, the big image quality of information storage is clear, can arbitrarily record a video or delete, and selects the purpose of TV programme to reach User Defined.
Memory adopts the queue stores mode of " first in first out " to deposit image data immediately simultaneously, does not therefore need to overflow auxiliary operations such as needing rewinding, tape swapping or deletion because of information when work as video tape recorder.Avoided excessive simultaneously, need spend a large amount of search times during playback because of amount of information.
Adopt digital form to deposit television image, therefore use common chip memory to satisfy the demand.Both dwindled the volume of product, reduced cost again, can also directly be embedded in the television set, and made television set improve a level.
The present invention can be connected in digital processing system between radio frequency decoder and the television set, be that signal arrives television set then through the internal memory of radio frequency decoder, digital processing system, so only use a radio frequency decoder also can realize the storage of instantaneous formula and the control principle that passes to when domestic of TV signal is similar at present overseas.
