Embodiment Construction

[0024] There is a plug-in (133) on the plasma display board assembly (120), and 9 pins are passed through the 25 pins of the plug-in (133) 2 The C bus (130) is connected with the 9-pin plug-in (131) of the digital set-top box (110), and the central processing unit (111A) of the digital set-top box (110) becomes an I 2 Master of the C-bus (130). I 2 Various signals (CC-PDP), (CC-DSTB), (PWR-IND), (PWR-IND-DSTB) of C bus (130), from image 3 can be seen in:

[0025] When the digital set-top box (110) and the plasma display panel assembly (120) are the same as I 2 When the C bus (130) is connected, a high-potential plasma display panel connection signal (CC-PDP) is sent from the plasma display panel assembly (120) to enter the microcomputer (112A) of the analog board (112), and the microcomputer (112A) can know The present situation on the plasma display panel assembly, the set-top box connected high potential set-top box connection signal (CC-DSTB) sent from the digital set-...

Abstract

The invention develops the connection device installed between the plasma panel module and the digital type set top box. No matter what device receives the infrared signal, the two devices can realize the control. The control is completed through the I2C bus. When the I2C bus is connected to the plasma panel, the control program of the system is set up and the power is controlled. With the infrared signal being received, the plasma panel transfers the signal to the set top box having the control function so as to realize the control. When the I2C bus is connected to set top box, the control program of the system is set up and the power is controlled. With the infrared signal being received, the set top box transfers the signal to the plasma panel having the control function so as to realize the control.

Description

technical field [0001] The present invention is to input a control signal to any one of the two devices from the outside, and both sides can be controlled. In particular, a connection device is set between the plasma display panel assembly and the digital set-top box. If the control signal is input to any one of them, They can all be controlled. Background technique [0002] The video signal output by a general digital set-top box is displayed through various display devices such as a plasma display panel assembly. The display device and the digital set-top box are independent of each other, and their control is accomplished through respective control keys. [0003] Historically, the digital set-top box and the plasma display panel assembly have been separate products, each controlled by a separate set of control keys. Therefore, bring a lot of inconvenience to use. Contents of the invention [0004] The purpose of the present invention is to arrange a connection device...
