Abstract: Multiple channels of received data are processed by a multiple channel demodulation and error correction decoding engine. The statistical uncertainty of processing channels with an iterative decoder are averaged across all the channels to reduce the total processing power required of the decoding engine compared to processing each channel with a separate engine. A set of input buffers holds blocks of data for each channel needing decoding. A quality measure is computed on each input block to set the priority and iteration allocation of decoding in the common decoder. The input RF signal is digitized by a broadband tuner that processes some or all of the channels to feed the multiple channel demodulator and decoder. Multiple decoded video data streams are output.

Abstract: In at least some embodiments, a system may comprise one or more devices configurable to communicate according to a first protocol that implements a first data packet, and one or more devices configurable to communicate according to a second protocol that implements a second data packet having a predetermined quadrature component. The one or more devices configurable to communicate according to the second protocol associate detection of the predetermined quadrature component with a function that is not supported by the one or more devices that communicate according to the first protocol.

Abstract: A system and method for managing resources in a distributed xDSL modem pool arrangement including a first number of front-end modules and a second number of back-end modules. In a preferred embodiment, when a back-end module identifies that its associated call session has entered idle-mode, idle-mode processing is performed in a manner which reduces processing load and electrical power consumption but does not result in a loss of synchronization or require retraining. A repetitively transmitted single modulated symbol transmitted from a user terminal device coupled to the modem pool indicates idle periods in user data. In the preferred embodiment, the modulated symbol to be transmitted is selected such that its spectral properties match those of user data modulated symbols.
