Abstract

Настоящее изобретение относится к способу управления цифровыми правами (DRM) мультимедиа-содержимого, к клиенту DRM, серверной стороне DRM, терминальному устройству и серверу DRM. Способ управления цифровыми правами (DRM) предусматривает прием клиентом DRM запроса на вызов мультимедийного приложения и извлечение уникального идентификатора мультимедиа-содержимого, которое должно воспроизводиться, из запроса на вызов; отправку запроса авторизации DRM на серверную сторону DRM для получения единицы выполнения авторизации содержимого, при этом запрос авторизации DRM содержит идентификатор мультимедиа-содержимого и базовую информацию клиента DRM; выполнение единицы выполнения авторизации содержимого в выполняемой среде клиента DRM с тем, чтобы получить функцию авторизации DRM. За счет технического решения согласно настоящему изобретению может быть обеспечена гибкая защита мультимедиа-содержимого и тем самым повышена степень безопасности мультимедиа-содержимого.The present invention relates to a digital rights management (DRM) method of multimedia content, to a DRM client, a DRM server side, a terminal device, and a DRM server. The digital rights management (DRM) method provides for a DRM client to receive a call request for a multimedia application and retrieve a unique identifier of the multimedia content to be played from the call request; sending a DRM authorization request to the DRM server side to get a unit for performing content authorization, the DRM authorization request contains the media content identifier and basic information of the DRM client; executing the content authorization execution unit in the DRM client runtime environment in order to obtain the DRM authorization function. Due to the technical solution according to the present invention, flexible protection of multimedia contents can be ensured and, thus, the safety level of multimedia contents can be increased.
