Embodiment Construction

[0048] A method and circuit for remote control of a set-top box by a video-recordable liquid crystal television

[0049] This circuit for remote control of a set-top box by a video-recordable LCD TV is shown in Figure 1, including a TV main controller 2 with an external interrupt port I / O-1 and a non-volatile memory 1, and an external interrupt port I / O-1 is connected with the television remote control receiving part 3 . Non-volatile memory 1 is a 24C32 with I 2 E of the C interface 2 PROM, through I 2 The C bus is connected to the TV main controller 2 . The main controller 2 of the TV adopts the 8051 core series micro-controller of the model 791632, and the command cycle of the micro-controller is less than 13 μs, which meets the requirement that the carrier of the remote control code transmission is 38KHz, and can decode the remote control code of the set-top box. The television remote control receiving part 3 adopts an integrated infrared receiving head whose model is S...

Abstract

The invention relates to a method for remotely controlling the set-top box of TV, wherein it comprises TV learns set-top box remote-control code at first time. and the learn process comprise that: (1), controlling TV to learn set-top box remote controller; (2), storing remote control code and building relation between remote control code and TV operation. And the following remote control comprises that: (1), selecting and reading remote control code; (2), sending remote control code to the set-top box. The invention also discloses a relative remote control circuit, with microcontroller with signal recognition and decode storage self-learn program. The TV has RS232 serial interface and connected infrared remote control emission diode. The invention can control TV remote controller to control TV and set-top box.

Description

technical field [0001] The invention relates to a remote control method for electrical appliances, in particular to a method and circuit for a TV set to remotely control a set-top box. Background technique [0002] The existing most extensive digital TV solution is realized through the combination of a set-top box and an ordinary digital high-definition TV. Not only can the TV set accept the original analog TV, maintaining mature technology and controllable cost, but also the set-top box can be sold separately to adapt to different decryption systems and program suppliers in various places. However, TV sets and set-top boxes are used to watch programs and should be integrated. However, two different remote controllers need to be used to control them separately, because there is no connection between the TV set and the peripheral electrical appliances and equipment including the set-top box. The connected control line and the program solidified in the main controller of the ...
