1. A return path of an optical network system comprising:

  • a video services controller for generating downstream analog RF modulated video service control signals that are converted to the optical domain, the video services controller being disposed at a first site; and

    a device for converting digitized, upstream, RF return packets to standard sized digital packets, the RF return packets comprising data derived from digitized and compressed upstream analog RF modulated video service control signals, the video service control signals comprising one or more commands for managing video prorammin that is displayable on a display device, the device comprising a scaling restoration unit for restoring information from compressed data contained within the RF return packets, the device being coupled to the video services controller, the device decompressing, restoring, and demodulating the upstream analog RF modulated video service control signals from the data contained within the RF return packets, the device further comprising a packet encapsulator for formatting the demodulated video service control signals into standard sized digital packets that are processed by the video services controller for managing video programming.
