two-way transmission device

Abstract

The invention discloses a two-way transmission device. The bidirectional transmission device includes a first computing unit and a second computing unit. The first arithmetic unit has a first input terminal and a first output terminal. The second arithmetic unit has a third input terminal, a fourth input terminal and a second output terminal. The third input terminal of the second computing unit is coupled to the first input terminal of the first computing unit. The fourth input terminal of the second computing unit is coupled to the first output terminal of the first computing unit. The fourth input terminal of the second arithmetic unit receives the first input signal, and outputs the first output signal through its second output terminal.

Description

technical field [0001] The present invention relates to bidirectional transmission of signals, in particular to a bidirectional transmission device capable of realizing bidirectional transmission of half-duplex control signals without using a special IC with high cost. Background technique [0002] Generally speaking, most traditional HDMI signal extenders (Extender) use dedicated ICs to solve the problem that bidirectional control signals cannot be compensated. The disadvantage is that the cost of the dedicated IC is too high, and the signal compensation is fixed and less flexible. [0003] In addition, the traditional HDMI signal extender can also use the Timing control method to control the transmission and reception of bidirectional signals through the enable control pin. However, since the timing control is difficult and not easy to implement, once the timing control is wrong, the signal feedback is likely to cause a data latch problem.
