Abstract
The utility model relates to a TV set, then is can TV TV set. The utility model in TV set in is provided with TV and device, has TV set in not. Used to the when has or the information,, economic information in telephone number, etc. and information. The utility model also can single device.
Description
The utility model relates to a kind of television set, the television set of the content that especially can return a TV show.
Television set is that people receive one of main source of various information because of the amount of information of playing is widely used in various aspects such as politics, economy, culture, education, family life more at present.Sometimes people are still unclear or forgotten to the content play, or only hear several of back, need check on again, as the major issue of domestic and international generation, time, place, telephone number, price etc. in the economic information.But because pictures and sounds that existing television set can only be reduced to TV signal and it changes synchronously, do not have the function that the content of broadcast program is initiatively stored.A lot of people feel inconvenience deeply, even lose many significant opportunity.
The purpose of this utility model is the television set that a kind of content that can return a TV show will be provided, and it can not only play TV programme, can also initiatively store programme content, and the content of the TV programme play of replaying tv machine when needed.
The purpose of this utility model is achieved in that the television set of the content that can return a TV show, comprise height, intermediate-frequency channel, sound channel, decoding and image display portion, power supply etc., television set also is provided with digital recorder device and the control circuit thereof of semiconductor memory as recording medium.The input of this digital recorder device can be received on the sound channel, when the television set normal play, receives, processes, stores the sound accompaniment audio signal; Also can receive on the high intermediate-frequency channel signal that when the television set normal play, receive, process, storage contains audio signal and composite colour television signal; Also can adopt the digital recorder device of two groups of synchronous workings, a winding receives, processes, stores audio signal to sound channel, and another winding is to the image detection level output of high intermediate-frequency channel, reception, processing, storage color composite video signal.When needs are reset the program of having play, make the sound accompaniment or the phonotape and videotape of television for play digital recorder device storage by operation control circuit.
Under above-mentioned three kinds of situations, store the digital recorder device of the signal that contains composite colour television signal and compare with the digital recorder device of storage sound accompaniment audio signal, both structures are identical, but the former memory capacity and sampling frequency are all greater than the latter.
During the playback sound accompaniment, the loud speaker of former television set can be adopted, also loud speaker or Headphone reproducing sound accompaniment can be established in addition.
When resetting image, can adopt the picture tube of former television set, also can adopt " picture-in-picture " technology, on former picture tube, ward off a place in addition and reset visual.
Consider that the time that single then information takies is about three minutes, so the time of the sound accompaniment of all storages of digital recorder device or phonotape and videotape is located at about three minutes accordingly, when the continuous operation of digital recorder device surpasses three minutes, recording/displaying device is the content of deletion typing before three minutes automatically, only keeps first three minute to the present information content during this period of time.
Owing to adopt such scheme, can reset needs to understand, but the programme content of having play, satisfies work needs in the life of people better, and because of only needing to increase replay device, and the time is not long, makes structure uncomplicated, easy realization.
Below in conjunction with drawings and Examples the utility model is further specified.
The utility model has following accompanying drawing:
Fig. 1 is the principle schematic of first embodiment of the utility model.
Fig. 2 is the principle schematic of second embodiment of the utility model.
Fig. 3 is the principle schematic of the 3rd embodiment of the utility model.
Among the figure 1, high intermediate-frequency channel; 2, put in the high intermediate-frequency channel; 3, high intermediate frequency channel images wave detector; 4, sound channel; 5, controlled switch; 6, sound channel low discharging grade; 7, control circuit; 8, digital recorder device; 9, controlled switch; 10, decoding and image display portion.
What Fig. 1 reflected is the situation that the digital recorder device stores and export the sound accompaniment audio signal in the utility model.
The television set of the content that can return a TV show is by high intermediate-frequency channel (1), sound channel (4), decoding and image display portion (10), power supply (not drawing among the figure), digital recorder device (8) and control circuit (7) thereof and affiliated controlled switch formations such as (5,9).Controlled switch (5) is serially connected on the input branch road of sound accompaniment low discharging grade (6), and controlled switch (9) is connected electrically between the input, output of digital recorder device (8), and the input of the input of digital recorder device (8) and sound accompaniment low discharging grade (6) is electrically connected.During the television set normal play, controlled switch (5) closure, controlled switch (9) disconnects, the audio signal that digital recorder device (8) receives, processes, stores sound accompaniment low discharging grade (6) input.When needs are reset the sound accompaniment of the TV programme play, by operation control circuit (7) controlled switch (5) is disconnected, controlled switch (9) closure, make television set break the sound accompaniment of in progress program, the signal of digital recorder device (8) storage is delivered to the input of sound accompaniment low discharging grade (6), the sound accompaniment of program for playback by output.
What Fig. 2 reflected is the situation that the digital recorder device stores and export the signal that contains composite colour television signal and sound accompaniment audio signal in the utility model.
The television set of the content that can return a TV show is by high intermediate-frequency channel (1), sound channel (4), decoding and image display portion (10), power supply (not drawing among the figure), digital recorder device (8) and control circuit (7) thereof and affiliated controlled switch formations such as (5,9).Controlled switch (5) be serially connected in high intermediate-frequency channel (1) in put the level (2) the output branch road on, controlled switch (9) is connected electrically between the input, output of digital recorder device (8), and the input of digital recorder device (8) is connected electrically between controlled switch (5) and image detection level (3) input.
During the television set normal play, controlled switch (5) closure, controlled switch (9) disconnects, digital recorder device (8) receives, processing, put the signal that contains composite colour television signal and audio signal of level (2) output in the storage, when needs are reset the TV programme of having play, by operation control circuit (7) controlled switch (5) is disconnected, controlled switch (9) closure, make television set break in progress program, the signal of digital recorder device (8) storage is delivered to the input and the sound channel (4) of image detection level (3), the phonotape and videotape that returns a TV show by output.
