DVR or Multiplexer

A Digital Video Recorder works the same way as a regular VCR, only digitally operated. When it is not recording, it can be used as a multiplexer.

A multiplexer is a communications device or equipment for combining several signals, such as data, voice, fax etc, to an aggregate stream of bits for transmission over a single medium or a public/private carrier. The multiplexer also provides compression and spoofing. The data is then separated and processed for outgoing purposes.
