摘要： A dynamic repository (either storing digital data content or pointers to stored digital data content) works in conjunction with a plurality of interfaces to manage digital content and digital rights policies associated with one or more users. Digital rights policies are unique to each user and such policies define access to digital content in the repository. The user's digital rights policy indicates the level of access a user has to digital content in the repository (e.g., the policy could indicate that the user has authorized access to a particular file for a period of seven days). The interfaces linked with the content repository are used to access and manipulate the digital data content (based upon each user's digital rights policy) and the digital rights policies stored in the content repository. The interfaces include: (a) one or more authentication interfaces for authenticating users, (b) one or more digital rights management (DRM) interfaces allowing users to add, delete, or edit the digital rights policies, (c) one or more data access interfaces allowing users to selectively access digital data content as defined by their individual digital rights policy, (d) one or more browsing interfaces allowing users to selectively browse said digital data content, or a (e) one or more content manipulation interfaces allowing said users to add, delete, or edit said digital data content.

摘要： Systems and methods for multi-rate media data delivery using multiple IP multicast streams are provided. According to example embodiments disclosed herein, the method may include determining a plurality of stream bit rates based on a plurality of demanded bit rates of a plurality of output media data streams and a first algorithm. The method may further include receiving an input media signal and generating a plurality of encoded data streams using the input media signal. The encoded data streams may have encoded bit rates, substantially the same as the stream bit rates. The example method may also include, using a second algorithm and the encoded data streams to generate output data streams at the demanded bit rates. In an example embodiment, the system may comprise a multi-rate encoder and a stream generator, to generate a plurality of encoded streams at the encoded bit rates.

摘要： A satellite transponder switch (STS) maintains a table that maps set-top boxes (STBs) to carrier frequencies. The STS receives a first request from a first STB for a first transponder band and a second request from a second STB for a second transponder band. The STS receives contact from the first STB on a control channel upon power-up of the first STB and in response to the contact from the first STB, assigns a first carrier frequency to the first STB. The STS frequency shifts the first transponder band to a first carrier frequency assigned to the first STB and the second transponder band to a second carrier frequency assigned to the second STB. The STS outputs a signal that comprises the frequency-shifted first and second transponder bands to the first STB and the second STB. The frequency-shifted first and second transponder bands are separated by a separation band. A first carrier frequency of the signal is unique to the first STB and a second carrier frequency of the signal is unique to the second STB.
摘要翻译：卫星转发器交换机（STS）维护一个将机顶盒（STB）映射到载波频率的表格。 STS从第一STB接收第一应答器频带的第一请求和来自第二STB的用于第二应答器频带的第二请求。 STS在第一STB上电时从控制信道上的第一STB接收联系，并且响应于来自第一STB的联系，向第一STB分配第一载波频率。 STS频率将第一应答器频带移动到分配给第一STB和第二应答器频带的第一载波频率到分配给第二STB的第二载波频率。 STS将包括频移的第一和第二应答器频带的信号输出到第一STB和第二STB。频移的第一和第二应答器频带被分离频带分离。信号的第一载波频率对于第一STB是唯一的，并且信号的第二载波频率对于第二STB是唯一的。

摘要： A system includes a signal-processing engine configured to generate a video data stream including a plurality of data packets based on a received video signal. A first subset of the plurality of data packets is usable to generate a video display of content having a first quality and all of the plurality of data packets are usable to generate a second video display of the content having a second quality. The second quality is higher than the first quality. The signal-processing engine is further configured to distinguish the first subset of the plurality of data packets from other data packets of the plurality of data packets by applying a tag to particular data packets to form tagged data packets. The system also includes a transmitter coupled to the signal-processing engine and configured to transmit the plurality of data packets of the video data stream.
