Patent ID: 7142604

Claim:
Transmitting apparatus wherein a digitized television IF signal is transformed into a transport channel bit-stream (TCBS) for transmission of said digitized television IF signal from a first location (FL) to one or more second locations (SL), comprising: a splitter (SP) for splitting a sample (S 1 ) of said digitized television IF signal into N most significant bits (MSB) and M−N least significant bits (LSB),; an encoder DPCM-core (D 1 ) for compression of the N most significant bits (MSC) of a sample (S 1 ) into a N−C bit compressed transport sample (CTS), generating a clipped prediction error ((e enc )c), an output for the transport channel bit-stream (TCBS),; a first location clipping detector (BSC 1 or BSC 12 ) which generates a first location PCM-bit substitution control signal (SC 1 ) indicating what is to be transmitted as residual transport sample (RTS), either the M−N least significant bits (LSB) of the sample (S 1 ) of the first digitized television IF signal, or a substitution value (CE) being a first function of both the clipping error corresponding to said sample S 1 of the first digitized television IF signal, and the M−N LSB of said sample (S 1 ) of the first digitized television IF signal, and a first location substitutor (BS 1 ) which substitutes the M−N least significant bits (LSB) by a substitution value (CE), depending on the value of the first location PCM-bit substitution control signal (SC 1 ).
