Patent

CA 2697177

A DVIS designed to be installed in an MDU/commercial property environment has a wall-mounted cabinet which integrates all the necessary technology for any of its intended applications. The cabinet can be opened in order to access the front panel to remove and/or add plug-in application cards. A channel deletion filter can be used to produce an empty QAM slot into which locally produced programming can be inserted. The invention is applicable to digital video encoding (e.g., MPEG-2 or MPEG-4), reception and demodulation, multiplexing and digital transmission (e.g., QAM modulation/transmission) and more specifically to a multiple-channel encoder suitable for use in a location at the edge of a broadband network. Depending on the terminology, the edge of the network can range from the last centralized point of a broadband service provider's architecture (e.g., Hub site for MSO) or even the to the subscriber premise itself.
