摘要： In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.

摘要： Shared secret data is used to authenticate and encrypt between a CDMA network and a GSM network such that a mobile station having a subscription in a GSM network can roam into a CDMA network and be authenticated to use the CDMA network and have messages encrypted without having a CDMA subscription. The goal of authenticating a GSM subscriber in a CDMA network using GSM authentication credentials is achieved by substituting a key Kc as SSD-A and messages are encrypted substituting Kc as SSD-B using a CAVE algorithm.

摘要： Methods and apparatus to optimize delivery of multicast content using probabilistic feedback. A method is provided for transmitting data from a server to a plurality of receiving terminals. The method includes transmitting the data from the server to the plurality of receiving terminals, and generating a random response value at each receiving terminal. The method also includes comparing the response value to an acknowledgement value at each receiving terminal, and transmitting an acknowledgment signal to the server from selected receiving terminals. The selected receiving terminals are a portion of the plurality of receiving terminals where the response value has a selected relationship to the acknowledgement value.

摘要： Methods and apparatus for conditional access of non real-time (NRT) content in a distribution system. A method includes encrypting NRT content with a control word (CW) to generate encrypted NRT content, providing the CW to entitlement control message (ECM) generators, receiving ECMs from the ECM generators, wherein each ECM comprises a unique encryption of the CW to provide conditional access to the CW, and providing the encrypted NRT content and the ECMs for transmission over a distribution network. An apparatus includes a synchronizer configured to provide a CW to ECM generators and receive ECMs from the ECM generators, wherein each ECM comprises a unique encryption of the CW to provide conditional access to the CW, and a management module configured to encrypt the NRT content with the CW to generate encrypted NRT content and provide the encrypted NRT content and the ECMs for transmission over the distribution network.
