摘要： A transport stream for conveying a program for a particular channel includes an auxiliary channel, which conveys multiple lower resolution programs associated with other channels. When a receiver has difficulty receiving a particular channel due to the geographical location of the receiver, the receiver tunes to a stronger signal associated with another channel and recovers a lower resolution version of the desired program from the auxiliary channel conveyed therein.

摘要： A content delivery system comprises at least one content server that servers a number of client requests. The content server uses a Threshold-Based Normalized Rate Earliest Delivery First (TB-NREDF) scheduler. The TB-NREDF scheduler imposes a threshold value, or limit, on the number of rescheduling requests.

摘要： Apparatus and methods for information transfer using a cache server are disclosed. A user requests a file via a file requesting device, over a network, from a host. The host transfers the file to a cache server over a connection at a first scheduled time. The cache server then transfers the file, over a second network, to a file receiving device at a second scheduled time.

摘要： A satellite communications system comprises a transmitting ground station, including a transmitter and a receiver, a satellite transponder and a receiving ground station. The transmitter transmits an uplink signal to the satellite transponder, which broadcasts the received uplink signal as a downlink signal to the receiving ground station. The transmitting ground station monitors the downlink signal through the receiver and calculates log-likelihood ratios (LLRs) as a function of the monitored downlink signal. These LLRs are illustratively stored in a look-up table, which are then transmitted to the receiving ground station for use in recovering data from a received data signal.

摘要： An apparatus includes a first signal receiving module, a second signal receiving module, and a signal transmitting module. The first signal receiving module is coupled between a first signal point and a third signal point for receiving a first RF signal from the first signal point. The first signal receiving module down-converts the first RF signal for providing a first down-converted signal at the third signal point. The second signal receiving module is coupled between a second signal point and the third signal point for receiving a second RF signal. The second signal receiving module down-converts said second RF signal for providing a second down-converted signal at the third signal point. The signal transmitting module is coupled between the first and second signal points and the third signal point for receiving a third RF signal from the third signal point. The signal transmitting module up-converts the third RF signal for selectively providing an up-converted signal at one of the first and second signal points in response to a selection signal.

摘要： System and method for providing a messaging service, such as a voice mail service over a digital subscriber loop are presented. An incoming call is first routed to a service processor. The incoming call is to be delivered over the digital subscriber loop to a receiving device. A determination is made as to whether or not the incoming call is answered by the receiving device. The incoming call is routed to a message processor if the incoming call is not answered by the receiving device. The incoming call is stored at the message processor for later retrieval.
