1. A system for integrating video content and data provision, the system comprising:
an upstream signal path configured to process an upstream data traffic received from a first transmission network for transmission to a second transmission network; and
a downstream signal path configured to process a downstream data traffic and downstream video traffic for transmission over downstream frequency channels from the second transmission network to the first transmission network,
wherein:
the upstream signal path includes an analog-to-digital converter (ADC) and an upstream demodulator;
the downstream signal path includes an Ethernet processor, a digital-signal-processor (DSP) and a digital-to-analog converter (DAC);
the downstream data traffic comprises a downstream first data;
the downstream video traffic comprises a downstream video content; and
the DSP comprises at least a digital channel combiner configured to combine the downstream first data and the downstream video content to allow the downstream first data and the downstream video content to co-exist in i) at least one of a narrowband modulation scheme or a wideband modulation scheme and ii) a single downstream channel of the downstream frequency channels.
