Description of drawings
Fig. 1 is the circuit process principle figure of the utility model.
Embodiment
Below in conjunction with specific embodiment the utility model is further specified.
Shown in accompanying drawing 1; The television set interface module of the described band advertisement information play of present embodiment function; It includes and is used for that the TV small-signal is handled, decoding/matrix, the television set master chip N1 that advertisement/information module N2 and electronic switch N3 are controlled; Be used for stores advertisements/information content, advertisement/information content is superimposed upon the advertisement/information module N2 on the vision signal; Be used to switch the electronic switch N3 of TV/AV1/AV2 signal; Wherein, interconnect between described television set master chip N1, advertisement/information module N2, the electronic switch N3, and the concrete condition of television set master chip N1, advertisement/information module N2, electronic switch N3 is following:
One, electronic switch N3 part, TV/AV1/AV2/AD state has following logical relation:
1, when SW1 is a low level, the TV of television set place state when SW2 is low level, electronic switch N3 only its 1 pin and 3 pin connects its 3 pin output TV vision signal.
2, when SW1 is a low level, the AV1 of television set place state when SW2 is high level, electronic switch N3 only its 5 pin and 3 pin connects its 3 pin output AV1 vision signal.
3, when SW1 is a high level, the AV2 of television set place state when SW2 is low level, electronic switch N3 only its 2 pin and 3 pin connects its 3 pin output AV2 vision signal.
4, when SW1 is a high level, the AD of television set place (advertisement/information) state when SW2 is high level, 3 pin of electronic switch N3 and other pin break off, 3 pin no-outputs.
Annotate: the vision signal of the 3 pin output of electronic switch N3 is transported to advertisement/information module N2.
Two, advertisement/information module N2 part; When+5V through a serial regulating circuit of forming by V1 obtain+3.3V is during to the 1 pin power supply of advertisement/information module N2; 7 pin of then advertisement/information module N2 can be exported advertisement/information module N2 internal video signal, are transported to 64 pin of television set master chip N1; Producing an amplitude simultaneously is that 3.3V, width are 200ms consecutive pulses square-wave signal, by its 8 pin output, is transported to 28 pin of television set master chip N1.After 3 pin of advertisement/information module N2 receive the vision signal of being exported by 3 pin of electronic switch N3; Advertisement/information module N3 can be superimposed upon advertisement/information content on the vision signal; Export the vision signal of the advertisement/information content that superposeed then by its 4 pin, be transported to 62 pin of television set master chip N1 again; Because advertisement/information module N2 connected capable field sync signal, and is connected mutually with master chip N1 bus, thus CPU can realize to advertisement/information program about the display position on the screen carries out, about etc. suitable adjustment.Because 12,13,14,15 pin of advertisement/information module N2 are the external input port of upgrading of advertisement/information content, can carry out real-time update to advertisement/information content through this port as required.
Three, television set master chip N1 part, its 62 pin are the vision signal input pin after advertisement/information content of having superposeed, and its 64 pin is for connecting advertisement/information module N2 internal video signal output pin; Existing through revising the software of television set master chip, it is defined as:
1, at the AD state; When 28 pin of television set master chip N1 receive when carrying the correct square-wave pulse signal of coming by 8 pin of advertisement/information module N2; Only connect the switch of its 64 pin and decoding circuit, decoding circuit will be to the decoding video signal of advertisement/information content.
2, at the TV/AV1/AV2 state; When 28 pin of television set master chip N1 receive when carrying the correct square-wave pulse signal of coming by 8 pin of advertisement/information module N2; Only connect the switch of its 62 pin and decoding circuit, decoding circuit will be to the decoding video signal of the advertisement/information content that superposeed.
In addition, 36,37 pin of television set master chip N1 are implemented logic control to electronic switch N3, that is to say that the path of whole passage is:
1, TV state: tuner-→ television set master chip N1-→ electronic switch N3-→ advertisement/information module N2-→ television set master chip N1-→ video amplifier circuit.
2, AV1/ AV2 state: the AV1/AV2 input port-→ electronic switch N3-→ advertisement/information module N2-→ television set master chip N1-→ video amplifier circuit.
