摘要： 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.

摘要： The invention relates to prioritising of data elements of a data stream for transmission to a receiving device including determining a decodability of data elements, wherein the decodability indicates the extent to which the current data element is decodable at the receiving device. Then, a priority is assigned to the data elements based on the determined decodabilities. A transmission of the data elements to a receiving device is then scheduled based on the priorities.

摘要： The invention relates to transmitting data elements of a data stream based on a priority and target buffer fill levels at a receiving device. A transmitter controller transmits data elements of a data element class with a highest priority first, for reaching an associated buffer fill level and then turns to data elements of successively lower priorities, until the available bandwidth is exhausted.

摘要： A technique that permits an earlier start of the decoding and play out of media frames received via a point-to-multipoint transmission is described. The media frames comprise frames of a first type that cannot be decoded without knowledge of supplemental information and frames of a second type that include the supplemental information. According to a method aspect of this technique, frames of the first type are received and immediately buffered without waiting for reception of a frame of the second type. In a next step, a request message requesting supplemental information required for a decoding of the buffered frames of the first type is sent. Upon receipt of the requested supplemental information, the buffered frames are decoded based on the received supplemental information.

摘要： A technique for controlling a download of an electronic service guide (ESG) for media content distribution services to a user device 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.

摘要： A system, method, and media edge proxy, MEP, (17) for providing media data such as Internet Protocol Television, IPTV, or Internet radio channels to a media client (12). The MEP obtains the media data from a media server (18) utilizing a temporary unicast connection and provides the media data obtained from the server to the media client for an initial time period. Upon determining that the initial time period has expired, the MEP obtains the media data via multicast from a multicast router (27), provides the media data obtained from the router to the media client, and releases the temporary unicast connection. The invention reduces channel switching delay and thus improves quality-of-experience for the end-user. The invention also avoids excessive IGMP JOIN/LEAVE signaling when a user switches quickly through channels.
摘要翻译：用于向媒体客户端（12）提供诸如因特网协议电视，IPTV或因特网无线电频道的媒体数据的系统，方法和媒体边缘代理（MEP）（17）。 MEP使用临时单播连接从媒体服务器（18）获取媒体数据，并将从服务器获得的媒体数据提供给媒体客户端一段初始时间段。在确定初始时间段已经到期时，MEP通过来自组播路由器（27）的多播获得媒体数据，将从路由器获得的媒体数据提供给媒体客户端，并释放临时单播连接。本发明减少了通道切换延迟，从而提高了终端用户的体验质量。当用户快速切换通道时，本发明还可以避免过多的IGMP JOIN / LEAVE信令。
