ABSTRACT:
A method and arrangement for optimizing bandwidth usage in a Multicast Services Control System (MSCS), which transports digital information in a multicast stream from a broadband network to a Set Top Box (STB) connected to a terminal TV. When the terminal TV is disabled, and can no longer utilize the multicast stream, the terminal TV sends a terminal status signal to the STB indicating deactivation of the terminal TV. In response, the STB sends an IGMP leave report signal to the broadband network, which then ceases its transmission of the multicast stream to the STB.
