Set top box system capable of realizing video telephone function in cable television network

Abstract

The invention discloses a set top box system capable of realizing a video telephone function in a cable television network. The set top box system is characterized in that the system comprises a digital television basic service processing module, a modulation-demodulation management module, a graphical display output module, a video telephone service processing subsystem and a system main task module; and a user registers on a video telephone service management server through the modules to obtain a telephone number, then call connection is conducted, input audio-video signals of a decoding camera and a microphone which are connected with universal serial bus (USB) interfaces on a set top box are transmitted to the set top box of another user for display and thereby conversion through the set top boxes can be realized. By using the existing radio and television digital television bilateral network, a high-definition television service and a video telephone service which originally belong to two different networks are integrated into one set top box terminal for realization, the integration of multimedia communication services is realized on one television for vast radio and television users, the market value of cable digital televisions can be promoted and the average revenue per user (ARRU) value of cable television operators can be improved.
