Abstract

The invention relates to a factory detection method, device and system of HDCP function. The method includes the following steps that: key information of a data source terminal, which is stored in advance, is read, and an HDCP authentication request message is transmitted to a detected terminal; response information sent back by the detected terminal is received, wherein the response information contains the key information of the detected terminal; the key information of the detected terminal is compared with the key information of the data source terminal, and whether HDCP function authentication on the detected terminal by the data source terminal is successful can be judged according to comparison results. With the method, device and system adopted, the problems of poor compatibility and the stability of device HDCP factory test existing in a traditional mode can be effectively solved, and improvement of test efficiency can be benefitted.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a factory inspection method, device and system for HDCP functions. Background technique [0002] With the development of HDTV (HighDefinitionTelevision, high-definition television), in order to adapt to the high bandwidth of high-definition television, HDMI (HighDefinitionMultimediaInterface, high-definition multimedia interface) technology has appeared. HDMI can provide high bandwidth to realize the lossless transmission of digital audio and video signals. In order to ensure that the high-definition signal transmitted by HDMI is not illegally recorded, when the user makes an illegal copy, HDCP (High-bandwidth Digital Content Protection, high-bandwidth digital content protection) technology can be used to interfere to reduce the quality of the copied image. Content protection for HDMI transmissions. [0003] At present, most high-definition digital devices (such as hi...
