摘要

The system has terminals (10, 12, 14) e.g. videophone, connected with a reception server (34) via Internet network (16). The server is connected with conference and computing servers (36, 38, 40). Each server allows to exchange media stream and connects the terminals connected to the server. A producer terminal (42) is connected to an input line of a mixing table (44) via a signal detect input (SDI)/phase alternating line (PAL) converter (46) that converts PAL format video stream into SDI format compatible with the table, where the stream is obtained by video capture of the terminals. Independent claims are also included for the following: (1) a method for direct broadcast of an interactive television service (2) a computer program comprising program code instructions for the execution of a method for direct broadcast of an interactive television service, when the program is executed on an interactive television service broadcast system.
