Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0052] The embodiment of the present invention provides a software upgrade method, which is applied to active DP cables. In order for those skilled in the art to understand DP cables more clearly, the figure 1 , introduce the DP cable.

[0053] Passive DP cables do not need to install signal repeaters, and active DP cables need to install signal repeaters. Furthermore, compared with the active DP cable, the structure of the passive DP cable is simpler, and th...

Abstract

The invention provides a software updating method and system and an active DP (display port) cable. A signal repeater in the active DP cable may acquire updated software through a data transmission port unit and a switch unit so as to arrive at software updating; breaking finished cables and stripping Re-driver cores from the finished cables as in the prior art are not required, availability of the finished cables is guaranteed, and production cost is lowered.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a software upgrading method, system and active DP cable. Background technique [0002] In order to avoid the attenuation of the input signal due to the loss of the transmission medium during the signal transmission process, an active DP cable (Active DP Cable) is often used to transmit the signal. The signal repeater Re-driver chip is embedded in the active DP cable. The Re-driver chip can compensate the frequency characteristics of the attenuated input signal due to the loss of the transmission medium and then send it out, so as to enhance the anti-interference ability and long-distance of the signal. distance transmission capability. [0003] After the signal repeater is installed in the active DP cable and becomes a part of the finished wire, when the firmware in the signal repeater needs to be upgraded, it is necessary to destroy the finished wire and strip...
