Digital movie playing server and movie playing control method

Abstract

The invention relates to a digital movie playing server and a movie playing control method. The digital movie playing server comprises a casing. A single embedded main board is arranged in the casing, is used for unpacking of release-edition movie program sources to led movie program sources, de-encapsulation of media exchange format, decryption of video streaming, decoding of video and audio and movie playing and can adopt a universal serial bus (USB) electronic key decryption mode or a secret key transmission message decryption mode at any time. Therefore, intercepting copyright infringement of signal flows of release-edition movie program sources is prevented effectively, an inside structure of a complete machine product is simplified, the physical connection is reduced, and the digital movie playing server is strong in stability and high in safety, simultaneously is compatible with a USB electronic key and a security account manager (SAM) chip, accords with two key delivery message (KDM) digital movie secret key issue management modes of digital movie plan organization norms, and has strong flexibility in market application and a multi-channel mode for issuing mid-range digital movie programs.

Description

technical field [0001] The present invention relates to a movie playing server, and more specifically, to a digital movie playing server and a movie playing control method. Background technique [0002] In the radio, film and television industry, when the current mid-range digital movie playback server decrypts the movie program source of the release version, it is implemented by software or an external separate hardware decryption module, and there is no key transmission that can realize the organization and specification of the digital movie program Information (KDM: Key Delivery Message) release management mode is a technology and product that is compatible with the security storage module (SAM, Secure Access Module) chip key release management mode adopted in my country's industry standard "Technical Specifications for Mid-Range Digital Cinema Projection System" . [0003] Mid-range digital movie playback server: unpack the data packets of the mid-range digital movie sour...
