A centralized interactive TV recording and reproduction system linking
several "Quality of Service" (QoS) reproduction and control units (such
as television and audio reproduction receivers), as well as high
bandwidth non-QoS legacy devices such as PCs, via a Home Area Network
(HAN) to a centralized media server, has novel traffic control to prevent
non-QoS devices from establishing and maintaining high-bandwidth network
connections during the real-time transmission of media (video and/or
audio) information from the media server to the QoS devices. In the
preferred embodiment, the media server also contains a gateway device for
connecting the HAN to a Wide Area Network, Metropolitan Area Network,
and/or the Internet, and the media server also receives video and audio
signals from sources such as cable, satellite, terrestrial broadcast,
etc. The media server also contains a network router. All traffic from
non-QoS devices is routed through the media server, and the media server
limits the delivery of packets sent from source non-QoS devices to
destination non-QoS devices. As a further refinement to prevent
interruptions in real-time transmissions of video and audio information
to QoS devices, the information can be buffered at the QoS device level.
