    Abstract: FEC (Forward Error Correction) decoder with dynamic parameters. A novel means by which FEC parameters may be encoded into, and subsequently extracted from, a signal stream to allow for adaptive changing of any 1 or more operational parameters that govern communications across a communication channel. FEC parameters are encoded directly into a data frame such that the data frame is treated identical to all other data frames within the signal stream. When the data frame actually includes FEC parameters, it is characterized as a CP (Control Packet) type. For example, when decoding an MPEG stream, an MPEG block that includes FEC parameters, that MPEG block is characterized as a CP MPEG block. The means by which FEC parameters are encoded and extracted from the signal stream allows for much easier adaptive modification of the manner by which signal are encoded, modulated, and processed within a communication system.

    Abstract: According to one exemplary embodiment, a front-end system for processing a composite wideband signal comprises a pre-receiving unit including a multiplexer for separating the composite wideband signal into a plurality of filtered signals. The front-end system further comprises a plurality of discrete frequency band outputs corresponding to the plurality of filtered signals, and a tuner/down-converter coupled to at least one of the plurality of discrete frequency band outputs. In one embodiment, the pre-receiving unit of the front-end system further comprises a second multiplexer for separating at least one of the plurality of filtered signals into a second plurality of filtered signals. In one embodiment, the pre-receiving unit may further comprise a low noise amplifier for processing at least one of the plurality of filtered signals before it is input to the second multiplexer.

    Abstract: A multiplexed transport interface (MTSIF) may be utilized during communication between a demodulation module and a video processing system-on-chip (SoC). The MTSIF may enable concurrent demodulation of a plurality of input modulated video streams, via a plurality of demodulator chips within the demodulation module, by multiplexing data generated by the demodulator chips via the MTSIF during communication between the demodulator module and the video processing SoC. The MTSIF may also be utilized for communicating control signals, which may be used in controlling and/or managing operations of the demodulation module, the video processing SoC, and/or the MTSIF. Communication via the MTSIF may be synchronized. Packets communicated via the MTSIF may be timestamped. Timestamp counters may be used in the demodulation module and the video processing SoC to generate and/or track timestamps in communicated packets. The timestamp counter may be synchronized, using control signals communicated via the MTSIF.
