    Abstract: A technique for controlling a download (110) of an electronic service guide (ESG) for media content distribution services to a user device (102) is proposed. First, a user behaviour related to the user device is monitored. Second, a ranking of fragments of the electronic service guide to be downloaded interactively onto the user device is determined, based on the monitoring. The download of one or more of the fragments to the user device is then initiated based on the ranking. This technique is particularly useful when a transmission capacity available for downloading fragments of the ESG is limited.

    Abstract translation: 提出了一种用于控制用于向用户设备(102)的媒体内容分发服务的电子服务指南(ESG)的下载(110)的技术。 首先,监视与用户设备相关的用户行为。 第二,基于监视来确定要交互地下载到用户设备上的电子服务指南的片段的排名。 然后基于排名来启动对用户设备的一个或多个片段的下载。 当可用于下载ESG片段的传输容量有限时,该技术特别有用。

    Abstract: A technique for controlling a play-out of a media data stream at a receiving device is provided. The media data stream comprises one or more programs, and each program comprises one or more program components. In a method implementation of the technique, a zone description is defined. The zone description is defined for a media zone for at least one program or at least one program component in the media stream and identifies the media zone for the at least one program or the at least one program component. In a next step, the zone description is associated to a program specific information data segment. The program specific information data segment is part of the media stream and comprises data specifying information at least regarding to the at least one program or at least one program component. The method also comprises transmitting the media data stream towards the receiving device.

    Abstract: A technique for protecting media content that is to be accessible via multiple media tracks of a media file is provided. A method implementation of this technique comprises the step of providing a set of one or more first layer data items that are to be accessible via a first media track, with each first layer data item being decodable to be rendered as a portion of the media content. Moreover, a set of one or more second layer data items is provided that are to be accessible via at least one second media track, with each second layer data item being decodable to be rendered in combination with at least one decoded first layer data item as an enhanced portion of the media content. With each second layer data item a track reference index is associated that allows to identify the first media track via which the first layer data items are accessible. Then, in a next step, the second layer data items and the associated track reference indices (plus optionally the first layer data items) are encrypted for being transmitted to a content recipient.

    Abstract translation: 提供了一种用于保护将通过媒体文件的多个媒体轨道可访问的媒体内容的技术。 该技术的方法实现包括提供要经由第一媒体轨道可访问的一组一个或多个第一层数据项的步骤,其中每个第一层数据项可解码以作为媒体内容的一部分被渲染 。 此外,提供一组一个或多个第二层数据项目,其经由至少一个第二媒体轨道可访问,其中每个第二层数据项目可解码以与至少一个解码的第一层数据项目组合地呈现为 媒体内容的增强部分。 利用每个第二层数据项,关联轨道参考索引,该轨道参考索引允许识别第一层数据项可经由其访问的第一媒体轨道。 然后,在下一步骤中,对第二层数据项和相关联的轨道参考索引(可选地加上第一层数据项)进行加密以传送给内容接收者。

    Abstract: Disclosed is a DRM device and method for providing secure linking to a user identity. A first request is sent to a subscriber identity module. A message is received from the subscriber identity module via a secure authenticated channel. The message comprises at least a a master key identifier, a random number, and a derived key. In response to the message, a second request is sent to a DRM server. The second request comprises at least a master key identifier, the device identifier, and a random number. Also disclosed is a DRM server and method for providing secure linking to a user identity. A first request is received from a DRM device. The first request comprises at least master key identifier, a device identifier, and a random number. The DRM device is authenticated. A second request for an application specific key is sent to a trusted key management server. The second request comprises at least a master key identifier. At least a key is received from the trusted key management server. A derived key is determined from the key received from the trusted key management server based at least on the device identifier and the random number. A challenge/response scheme is used to determine whether the derived key of the DRM server matches a derived key of the DRM device.

    Abstract: A technique for registering a device (10) with a rights issuer system (12) in a digital rights management (DRM) context is described. The device (10) is provided with DRM registration information that is required to use protected content. The DRM registration information is generated from rights issuer information on the one hand and device information on the other hand. The DRM registration technique described herein does not require an interactive registration protocol between a rights issuer server (12) and the device (10). Rather, the DRM registration information may be generated and transferred to the device (10) even if the device (10) is offline, inactive or switched-off.
