The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and providing a kind of can carry out the video recording of scheduled time scheduled program automatically at the holding state of television set under the situation of no supervision; And simple to operate, preservation convenience, need not the television set that other people help with self-timing recording function.
Summary of the invention
In order to achieve the above object, the utility model is made of casing and the TV movement circuit that is installed in the casing.The TV movement circuit comprises antenna and high-frequency tuner, Infrared remote controller, infrared remote receiver reach and its main control microprocessor that is connected successively, memory, handle and the chroma decoding circuit with the luminance signal that main control microprocessor is connected with high-frequency tuner, with line output, an output and display that luminance signal is handled and the chroma decoding circuit is connected and standard commutation circuit, AV/TV change-over circuit, two channel audio signal input-switching circuits, audio-frequency power amplifier and loud speaker and the power circuit that is connected successively with luminance signal processing and chroma decoding circuit.The TV movement circuit is connected with the DVR movement circuit by two block mode change-over circuits, and they are installed in the same casing.Thereby constitute a television set with self-timing recording function.
Between TV movement circuit and the DVR movement circuit be: TV RF signals end RF VIDEO input pattern change-over circuit 1 with two block mode change-over circuit ways of connecting, the audio signal end is input pattern change-over circuit 1 and mode switching circuit 2 simultaneously, the AV signal end is input pattern change-over circuit 1 and mode switching circuit 2 simultaneously, selector switch SW1 is connected with mode switching circuit 1, the sound of mode switching circuit 1, video output terminals is connected with the DVR movement circuit, the output of DVR movement circuit is connected with the input of mode switching circuit 2, selector switch SW2 is connected with mode switching circuit 2, the sound of mode switching circuit 2, video output terminals is connected with the TV movement circuit.
Two mode switching circuits constitute by TC4053 type integrated circuit.
Operation principle of the present utility model is as follows:
When watching ordinary tv programme: when DVR watches ordinary tv programme, all signals (comprising video, audio frequency) all without the mode switching circuit conversion, directly enter the TV movement circuit.When watching ordinary tv programme through DVR, choose the radiofrequency signal (RF) of mode switching circuit 1 to deliver to the DVR movement circuit by selector switch SW1, after handling and storing, deliver to mode switching circuit 2, choose the DVR signal to deliver to the TV movement circuit by selector switch SW2 again.
When watching the AV TV programme: when watching the AV TV programme, choose the AV signal directly to deliver to the TV movement circuit by selector switch SW2 without DVR.When watching the AV TV programme by DVR, at first choose the AV signal to deliver to the DVR movement circuit by selector switch SW1, after handling and storing, deliver to mode switching circuit 2, choose the DVR signal to deliver to the TV movement circuit by selector switch SW2 again.
Task of the present utility model comes to this and finishes.
The utility model provides a kind of can carry out the video recording of scheduled time scheduled program automatically at the holding state of television set under the situation of no supervision; And simple to operate, preservation convenience, need not the television set that other people help with self-timing recording function.It can be widely used in family, the hotels and other places.
