Abstract

The embodiment of the invention discloses an authentication method and device for HDMI equipment, and television equipment, wherein the method comprises the following steps of: obtaining HDMI signals of the HDMI equipment; extracting equipment identification information from the HDMI signals; searching a pre-stored authentication database according to the extracted equipment identification information, and, if the corresponding authentication data is searched, playing the HDMI signals; and, if the corresponding authentication data is not searched, generating alarm information that the HDMI equipment is not authorized. By means of the embodiment of the invention, the problem that electronic playing equipment with an HDMI interface can play audio and image signals in the HDMI signals sent by any HDMI equipment can be solved; therefore, the electronic playing equipment with the HDMI interface can identify the authority of the HDMI equipment; and thus, only audio and image signals in the HDMI signals sent by the authorized HDMI equipment are played.

Description

technical field [0001] The invention relates to television application technology, in particular to an authentication method and device for HDMI equipment and television equipment. Background technique [0002] The TV is an electrical device that passively receives signals. During use, the external device provides the TV with an input signal of HMDI (High Definition Multimedia Interface, High Definition Multimedia Interface). After the TV receives the HDMI signal, it performs analysis and processing, and then The analyzed image is displayed on the display screen, and the analyzed sound signal is played through the speaker. [0003] When promoting the company's HDMI digital set-top box products, cable TV operators often use some marketing methods in order to increase the competitiveness of the products. For example, ordering the company's HDMI digital set-top box will give a branded LCD TV as a gift. Since the profit model of cable TV operators is to charge the use of digita...
