摘要:
An outer symbol error correcting code is concatenated with a punctured multidimensional trellis code to provide an optimal scheme for communicating digital television signals in a standard (e.g., approximately six MHz) bandwidth channel via a cable television network or the like. An input signal is encoded using an outer symbol error correcting code to produce successive blocks. Each block comprises N seven-bit coded symbols of which M represent information to be communicated and the remaining N-M coded symbols comprise error correcting information. M/N is either 120/126, 121/127 or 122/128. The blocks are interleaved, and may be supplemented with control symbols that include a synchronization pattern for M/N=121/127 or M/N=122/128. The interleaved blocks are convolutionally encoded using an inner trellis code having a punctured rate 4/5 (sixty-four QAM) or 3/4 (sixteen QAM). The output symbols are multilevel modulated for transmission over a communication path using, for example, sixteen or sixty-four QAM. The transmitted symbols are decoded using a trellis decoder, deinterleaved, and further decoded in an outer symbol error decoder concatenated with the inner trellis decoder.

摘要:
Block coded digital data is communicated with associated overhead data in a data stream having a succession of coded blocks. Each block contains N symbols wherein M of the symbols comprise information to be transmitted and the remaining N-M of the symbols comprise error correcting data. The ratio M/N comprises a first information rate. The coded blocks in the data stream are divided into a succession of frames, each comprising F of the coded blocks. A frame overhead symbol is added for each of the frames, to provide the data necessary for a receiver function such as synchronization. The addition of the frame overhead symbols effectively lowers the first information rate to a second desired information rate. A plurality of X of the frames are formed into a superframe containing FX coded blocks and associated frame overhead symbols. X is chosen to provide enough n-bit frame overhead symbols to implement the desired receiver function.

A configurable leverage bit driver includes a first elongate shaft having a first bit receiving socket in an end face of the distal end. A second elongate shaft is dimensioned to couple with the first elongate shaft in a first axially aligned bit driving configuration. At least one aperture is defined in a lateral side of the second elongate shaft and is dimensioned to selective couple with the first elongate shaft to configure the first elongate shaft and the second elongate shaft in a second bit driving configuration with the second elongate shaft oriented as a lever arm aligned in a transverse axis to the longitudinal axis of the first elongate shaft. The second bit driving configuration may be one or more of a T-handle or an offset T-handle bit driver for increased leverage in driving a fastener.
