Embodiment Construction

[0075] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0076] Considering that the existing HDCP key programming method has the problems of low programming efficiency and waste of HDCP key resources, this application never requires an external programmer or a programming socket, and needs to be programmed before placement and directly online. Based on the requirement of burning and supporting simultaneous burning ...

Abstract

The embodiment of the present application provides a HDCP key online burning method, device and electronic equipment, the method includes: according to the unburned target HDCP key format identification corresponding to the target equipment, from the external storage device communicatively connected to the target equipment to search Whether there is a corresponding HDCP key file, if yes, and there are multiple corresponding HDCP key files of different versions in the external storage device, then judge whether the serial numbers of the HDCP key files of multiple different versions are the same; if they are the same, then simultaneously Burn multiple HDCP key files of different versions into the target device online. The application can accurately and reliably burn multiple versions of HDCP keys online and directly to the target device at the same time, can effectively improve the HDCP key burning and production efficiency of the target device, and effectively avoid waste of HDCP key resources.

Description

technical field [0001] This application relates to the technical field of device programming, and in particular to an HDCP key online programming method, device and electronic equipment. Background technique [0002] In order to ensure that high-definition signals transmitted by high-speed digital video interfaces (Displayport, HDMl, DVI) will not be illegally recorded, high-bandwidth digital content protection technology, namely HDCP (High-bandwidth Digital Content Protection) technology, HDCP is a kind of High bandwidth digital content protection technology, used to protect uncompressed digital audio and video content. [0003] HDCP needs the joint support of software and hardware, and all devices involved in content transmission are indispensable. Every product that supports HDCP technology will burn a unique key HDCP key file during the production process to protect the content information of the product from being illegally recorded. At present, the existing burning me...
