Abstract
Automatic monitor for full frequency channel TV program of the present invention belongs to the integrated application field of electrical signal detection, conversion and control, is to be used for monitoring automatically the slotting device of situation that reflects of each channel TV program.Utilization of the present invention is installed in the program monitoring circuit in the television set, TV signal to current whole channels of being embedded with distinctive mark is monitored, initiatively provide frequency-selecting road program information converting in addition, and have the function that program channel information has been selected in memory to spectators.
Description
The invention belongs to TV programme and broadcast situation monitoring device, it relates to the integrated application of electrical signal detection, conversion and control, is new class TV programme automatic monitoring device.
The TV programme monitoring arrangement is that spectators select program channel to watch satisfied TV Festival destination device for convenience.Usually employing is watched each channel program in turn or is monitored, selects new channel with the mode of double-menu television.
Watch that in turn each channel program can or utilize the channel automatic change-over to carry out the timing conversion and realize by the random manual control of spectators, its shortcoming is that aimless search can influence normally watching of frequency-selecting road, and the channel switch of passivity can not reach the purpose that other channel program is seen in timely commentaries on classics.Double-menu television is normally watched frequency-selecting road program with key frame, monitor that with secondary picture other channel program broadcasts situation, secondary picture both can be fixed on a certain other channel, also can search for whole channels automatically in turn, its shortcoming is that major and minor picture needs to overlap independently circuit such as high-frequency tuning, intermediate frequency amplification, video detection separately, secondary picture also needs a cover analog/digital converter, digital/analog converter and jumbo image memory board to realize the synchronous broadcast of major and minor picture, complex structure, cost is higher.
The present invention's " automatic monitor for full frequency channel TV program " designs for overcoming above-mentioned defective, solved and watched normally under the prerequisite of frequency-selecting road program that program information converting to other channel effectively monitors so that the timely problem of converted channel, and can remember and select program channel information.
The present invention is achieved in that and utilizes the program monitoring circuit that is installed in the television set, each the channel TV signal that is embedded with distinctive mark is monitored, initiatively provide frequency-selecting road each channel program information converting in addition, and program channel has firmly been selected in memory to spectators.
Hereinafter with reference to accompanying drawing device implementation method of the present invention is further described.
Fig. 1 is an electric theory diagram of the present invention, wherein is the original circuit of television set in the frame of broken lines, comprises antenna (6), high-frequency electronic tuner (7), intermediate frequency amplifier (8), vision signal detector (9) and subsequent conditioning circuit thereof.
The present invention's " automatic monitor for full frequency channel TV program " is made up of program monitoring circuit and the TV signal that is embedded with distinctive mark.
Described program monitoring circuit is installed in the television set, both can have an independently circuit board of one's own, and also the available cell circuit form is incorporated into respectively in the original circuit board of circuit machine.
With reference to Fig. 1, described program monitoring circuit comprises channel selector (1), all-channel monitor (2), channel information outage retainer (3), channel indicator (4) and landmark detector circuit parts such as (5).
Distinctive mark in the described embedding TV signal is the program that a kind of special marking signal is inserted into normal tv signal to be begun or end and the program conversion marking signal that forms, the as a token of recognition objective of detector (5).
Channel selector (1) is used for selecting the program channel normally watched, both available soft-touch control control, and also available remote control mode is realized.
All-channel monitor (2) can automatically monitor current each channel program situation of broadcasting and not influence normally watches the visual effect of frequency-selecting road program.
Channel information outage retainer (3) can remember automatically when power supply cuts off the power supply firmly and selected program channel, and when powering again the original program channel of automatic recovery.
Landmark detector (5) can detect and be embedded in that TV programme begins or the program conversion marking signal of ending place, and control channel indicator (4) is reacted.
Channel indicator (4) can also of short durationly show other channel number of program change situation when receiving the control signal that landmark detector (5) is sent except energy steady display frequency-selecting road sequence number.
After the TV signal that is embedded with program conversion marking signal is received by TV set aerial (6), be sent to the high-frequency electronic tuner (7) that is subjected to all-channel monitor (2) control and locate to carry out frequency-selecting and amplify.All-channel monitor (2) monitors current each channel program situation of broadcasting again and again, make landmark detector (5) analyze, to differentiate to taking from vision signal detector (9) each channel signals afterwards, when finding program conversion marking signal, control channel indicator (4) is reacted, when steady display has been selected the program channel position number, the of short duration channel position sequence number that shows program conversion marking signal, initiatively provide the program information converting of other channel, so that in time change the program of seeing other channel to spectators.
Selected program channel information to be preserved by the channel information retainer (3) that cuts off the power supply, and irrelevant with the power supply electric power thus supplied.
Implementing the present invention need be arranged the form of program conversion marking signal by means of certain administration means, so that realize effectively.
Claims (8)
