Abstract

Systems, apparatus and methods are described including operations for demodulating, via a front end demodulator of an analog front end processor, at least a portion of digital sample data into front end demodulated data. A framer of the analog front end processor may frame data from a selection of the front end demodulated data as well as undemodulated digital sample data remaining from the digital sample data, into frames of front end demodulated data and/or undemodulated digital sample data.

Claims (33)

1. A method for transferring data between elements of a cable communication device, comprising:

demodulating, via a front end demodulator of an analog front end processor, only a portion of a plurality of channels into a first portion of front end demodulated channels while leaving a remaining second portion of the plurality of channels as undemodulated channels;

framing, via a framer of the analog front end processor, data from a selection of the front end demodulated channels as well as the undemodulated channels remaining from the plurality of channels, into frames of front end demodulated data and/or undemodulated digital sample data;

transferring, via the analog front end processor and a digital processor, the frames of front end demodulated channels and/or undemodulated channels from the analog front end processor to the digital processor;

deframing, via a deframer of the digital processor, the frames of front end demodulated data and/or undemodulated digital sample data, into front end demodulated channels and/or undemodulated channels; and

demodulating, via a backend demodulator of the digital processor, only the remaining second portion of the plurality of channels from undemodulated channels into remaining demodulated channels after the framing operation and after the deframing operation is performed.

2. The method of claim 1 , wherein the front end demodulated channels include MPEG2 transport stream-type data and the undemodulated channels include inphase component-quadrature component-type sample data.

3. The method of claim 1 , wherein the analog front end processor is configured to demodulate 8 of 32 channels and the digital processor is configured to demodulate 24 of 32 channels.

4. The method of claim 1 , further comprising:

wherein the front end demodulated channels include MPEG2 transport stream-type data and the undemodulated channels include inphase component-quadrature component-type sample data,

wherein the analog front end processor is configured to demodulate 8 of 32 channels and the digital processor is configured to demodulate 24 of 32 channels.

5. An analog front end processor of a cable communication device, comprising:

a front end demodulator configured to demodulate only a portion of a plurality of channels into a first portion of front end demodulated channels while leaving a remaining second portion of the plurality of channels as undemodulated channels, wherein the remaining second portion of the plurality of channels are to be demodulate from undemodulated channels into remaining demodulated channels after the framing operation only via a separate backend demodulator;

a framer configured to frame data from a selection of the front end demodulated channels as well as the undemodulated channels remaining from the plurality of channels, into frames of front end demodulated data and/or undemodulated digital sample data;

the analog front end processor being configured to:

transfer the frames of front end demodulated data and/or undemodulated digital sample data from the analog front end processor to a digital processor; and

demodulate 8 of 32 channels so as to work with the digital processor configured to demodulate 24 of 32 channels.

6. The analog front end processor of claim 5 , wherein the front end demodulated channels include MPEG2 transport stream-type data and the undemodulated channels include inphase component-quadrature component-type sample data.

7. A system for transferring data between elements of a cable communication device, comprising:

an analog front end processor, comprising:

a front end demodulator configured to demodulate only a portion of a plurality of channels into a first portion of front end demodulated channels while leaving a remaining second portion of the plurality of channels as undemodulated channels;

a framer configured to frame data from a selection of the front end demodulated channels as well as the undemodulated channels remaining from the plurality of channels, into frames of front end demodulated data and/or undemodulated digital sample data; and

a digital processor associated with the analog front end processor, the digital processor comprising:

a deframer configured to deframe the frames of front end demodulated data and/or undemodulated digital sample data, into front end demodulated channels and/or undemodulated channels; and

a backend demodulator configured to demodulate only the remaining second portion of the plurality of channels from undemodulated channels into remaining demodulated channels after the deframing operation.

8. The system of claim 7 , wherein the front end demodulated channels include MPEG2 transport stream-type data and the undemodulated channels include inphase component-quadrature component-type sample data.

9. The system of claim 7 , further comprising:

the analog front end processor being configured to transfer the frames of front end demodulated data and/or undemodulated digital sample data from the analog front end processor to the digital processor.

10. The system of claim 7 , wherein the analog front end processor is configured to demodulate 8 of 32 channels and the digital processor is configured to demodulate 24 of 32 channels.

11. The system of claim 7 , further comprising:

wherein the front end demodulated channels include MPEG2 transport stream-type data and the undemodulated channels include inphase component-quadrature component-type sample data,

the analog front end processor being configured to transfer the frames of front end demodulated data and/or undemodulated digital sample data from the analog front end processor to the digital processor; and

the analog front end processor being configured to demodulate 8 of 32 channels and the digital processor being configured to demodulate 24 of 32 channels.
