Embodiment 1

[0048] Embodiment 1: The data signal transmission medium is copper wire.

[0049] see figure 2 , when the data wire 4 is a copper wire, the data signal control module 5 is a data signal repeater (Redriver, Repeat) 51 .

[0050] The feedback control module 6 communicates with the data signal repeater 51 and / or the display terminal 8, so as to obtain the signal transmission quality in the cable.

[0051] specific:

[0052] see Figure 5 , the feedback control module 6 communicates with the data signal repeater 51, obtains the current data signal transmission speed and frequency, actively adjusts the configuration information in the data signal repeater 51, and directly configures the data with parameters suitable for different speeds and frequencies The signal repeater 51 allows the data signal repeater to operate according to the specified configuration.

[0053] The feedback control module 6 communicates with the data signal repeater 51, adjusts and actively adjusts the c...

Embodiment 2

[0056] Embodiment 2: The data signal transmission medium is an optical fiber

[0057] see figure 2 , when the data line 4 is an optical fiber, the data signal control module 5 includes a high-speed electro-optical conversion module 52 located at the sending end of the data line 4, and a high-speed photoelectric conversion module 53 located at the receiving end of the data line 4, and the feedback control module 6 includes a high-speed electro-optical conversion module located at the receiving end of the data line 4 The sending end control module 61 of the sending end, and the receiving end control module 62 positioned at the receiving end control module, the sending end control module 61 communicates with the high-speed electro-optic conversion module 52, and the receiving end control module 62 communicates with the high-speed photoelectric conversion module 53 respectively To communicate with the display terminal 8, the control module 61 of the transmitting terminal and the ...

Abstract

The invention relates to a self-adaptive HDMI cable. A feedback control module is arranged in the HDMI cable to actively detect the current signal quality. For example, communication with a display terminal (Sink) is carried out. Or communicating with a data signal control module capable of controlling the transmission of the data signal in the cable, then adjusting the corresponding parameters ofthe cable, such as output amplitude, pre-emphasis and the like, changing the input and output of the high-speed signal until the signal of the whole system is optimal, and storing the related parameters so as to facilitate the direct setting when the system is started next time. The system signal transmission signal state is obtained in real time, parameters are adjusted in real time according tothe state, and self-adaption of the cable in the system and the environment is completed. Compared with a traditional HDMI cable, the HDMI cable is more beneficial to signal stability and optimal transmission, and is more suitable for application scenarios of dynamic environment change and system switching.

Description

technical field [0001] The present invention relates to an HDMI connection cable, in particular to an adaptive HDMI cable, which is applicable to the transmission modes of copper wire and optical fiber. Background technique [0002] With the development of high-definition video technology, more and more videos use high-definition playback sources to play high-definition videos such as 1080P and 720P. In order to enable high-definition TV to play high-definition video, it is necessary to transmit the above-mentioned high-definition video from the high-definition video source to the high-definition terminal through a high-capacity connection line, and the high-definition connection line has become a key link. High Definition Multimedia Interface (HDMI) is a digital video / audio interface technology. It is a dedicated digital interface suitable for image transmission. It can transmit audio and video signals at the same time. The maximum data transmission speed is 18GB / s . [0...
