Abstract

A method and apparatus for monitoring use patterns or services available information in video distribution networks. A network termination unit receives the video content through a port, demodulates and decodes the signals to produce display signals. The display signals are displayed on a viewing device connected to the network termination unit and the network termination unit monitors the use patterns and/or services available information of the viewing device. The unit then formats the use patterns or services available information into use pattern network packets and transmits them. A content analyzer receives use pattern packet from a network termination unit and decode them to access the data. The content analyzer then analyzes the use patterns and/or services available information and characterizes the unit. The characterization of the unit is then used to target content to that unit.

detect use patterns of a user viewing display signals on a viewing device,

transmit the use patterns as use pattern packets,

detect services available information, the services available information indicating an availability of services at the network termination unit, and

transmit the services available information in the use pattern packets.

7. The network termination unit of claim 1, wherein the decoder is also operable to decode the demodulated content signals into command and control signals.

33. The network termination unit of claim 1, further comprising a module operable to monitor a quality of service of the content signals.
