Abstract
Systems and methods are provided herein for interfacing a first digital device with a second digital device. An exemplary method includes the steps of combining one of a plurality of digital content channels and a back channel to form a composite channel, the back channel for transmitting information from the second multi-media digital device to the first multi-media digital device, converting a digital content channel and the composite channel from the first digital device into a plurality of single-ended digital content channels, transporting the plurality of single-ended digital content channels from the first digital device to the second digital device, and converting the single-ended digital content channels back into the digital content channel and the composite channel that are supplied to the second digital device. Cross-talk interference is reduced between the back channel and one of the plurality of digital content channels via a cross-talk cancellation filter.
