Embodiment Construction

[0038] refer to figure 1 , the HDCP KEY sending method in one embodiment can be applied to the server, including the following steps.

[0039] S110: Obtain the programming application information sent by the receiving end.

[0040] The receiving end refers to the device that needs to burn the HDCP KEY, such as a playback device or display device that supports HDCP technology. Through the online communication connection with the receiving end, the programming application information sent by the receiving end can be obtained.

[0041] The burning application information may include operating system information, hardware information, serial number and MAC (Medium Access Control) address of the receiving end. Wherein, the operating system information refers to the type and version of the operating system of the receiving end, for example, the version of the Android (Android) system, the version of the ios system or the version of the Windows system; the hardware information refe...

Abstract

The invention relates to HDCP KEY (high-bandwidth digital content protection key) transmitting and burning methods and transmitting and burning devices. The HDCP KEY transmitting method includes: acquiring burning application information transmitted by a receiving terminal; acquiring matching format of data processable by the receiving terminal according to the burning application information; selecting a HDCP KEY from a pre-stored KEY file; subjecting the selected HDCP KEY to format conversion to generate a HDCP KEY of matching format that is transmitted to the receiving terminal so that the receiving terminal performs burning operation according to the HDCP KEY of matching format. The HDCP KEYs are transmitted by online communicative connection with the receiving terminal and are pre-stored and managed centrally in the form of Key files, with no need for the use of extra storage devices, the HDCP KEYs can be transmitted according to the matching format of the data processable by the receiving terminal, with no need for extra format conversion tools, the operation is simple, and HDCP KEY transmitting efficiency is high.

Description

technical field [0001] The invention relates to the technical field of data burning, in particular to an HDCP KEY sending method, burning method and device. Background technique [0002] HDCP (High-bandwidth Digital Content Protection) protection technology encrypts the digital signal transmitted through the digital video interface, between the sending end of multimedia content (computer, DVD, set-top box, etc.) , projectors, etc.) with a protection between. The HDCP Key is used on playback devices or display devices that support HDCP technology. Usually, the HDCP KEY is burned into the memory of the device before the device leaves the factory, and the HDCP KEY used by each device is different. [0003] The traditional method of burning HDCP Key is: intercept the required number of HDCP Keys from all purchased HDCP Keys and convert them into the required format; when the device is produced, put the intercepted HDCP Keys Read the HDCP Key from the U disk, and burn the read ...
