| Zusammenfassung: | A video modulator (114) modulates a baseband video telephony signal received from a communication system (102) to produce a modulated video telephony signal.

The subscriber can view the video telephony signals on any television (122) connected to the subscriber cable network (118) by tuning the television (122) to the frequency of the subscriber channel bandwidth. |
