    摘要： A communications system serves as a proxy for a user device in a communications network. The communications system includes a network gateway that receives content in response to a user initiated content utilization attempt from a user device. A computer receives the content from the network gateway and, in response to receiving the content, determines whether the content utilization by the user can be permitted. The computer can also determine whether the content utilization by the user can be completed.

    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 system and method of processing a satellite signal is disclosed. In a particular embodiment, the method includes receiving a satellite signal at a receiver, where the satellite signal includes a Moving Picture Experts Group (MPEG) portion and a radio frequency (RF) portion. The method also includes decoding the satellite signal to produce a digital MPEG transport stream signal that includes the MPEG portion, by removing the RF portion from the satellite signal without substantially altering the MPEG portion. The method also includes transmitting the digital MPEG transport stream signal to a vestigial sideband (VSB) modulator, where the VSB modulator transmodulates the digital MPEG transport stream signal to a VSB signal.

    摘要： A method of distributing content includes receiving at least one request for a particular content item. Based on the at least one request, a number of users who are to receive the particular content item and are capable of receiving the particular content item via a wireless link is determined. Based on the number of users, at least one of a wireline link and the wireless link from which the users are to receive the particular content item is selected. The particular content item is distributed to the users via the selected at least one link.

    摘要： A content broker hosting service is disclosed that includes a broker module configured to facilitate the management of digital content of an Internet user. The content broker hosting service supports a single sign-on user account that permits a subscriber to login to the content broker hosting service and other third party content providers that permit the sign-on credentials to be “federated” and used on their respective sites. Users may purchase content on the content hosting service site or from third party providers. The content hosting service maintains a directory of the devices a subscriber owns and of the content purchased. The rights usage policies and associated license keys are maintained on the hosting service to provide a digital “proof of purchase” for the content. In the event the content is lost by the subscriber, or if the subscriber chooses to change digital rights policies associated with the content, the broker hosting service may communicate with third party providers and negotiate for replacement content on the user's behalf.
