There is disclosed an apparatus for updating a viewer profile stored in a digital television device. The apparatus comprises: 1) receiver circuitry for receiving audio-video data packets associated with a plurality of incoming television signals and extracting therefrom at least one data request data packet containing a first data request operable to retrieve a first requested profile datum from the stored viewer profile; and 2) an update controller for receiving the at least one data request data packet from the receiver circuitry and determining if the first requested profile datum is present in the viewer profile, wherein the update controller, in response to a determination that the first requested profile datum is not present in the stored viewer profile, displays on an associated television screen information related to the first requested profile datum.

Apparatus and method for dynamically updating a viewer profile in a digital television device

There is disclosed an addressable advertising system comprising: 1) receiver circuitry for receiving an incoming television signal from an external source, generating a original baseband video signal, and transmitting the original baseband video signal to a display associated with the addressable advertising system; 2) a local storage device coupled to the receiver circuitry for storing a plurality of replacement video advertisements; and 3) an advertisement controller coupled to the receiver circuitry and the local storage device for detecting a first swap control signal transmitted in the incoming television signal. In response to the detection of the first swap control signal, the advertisement controller causes the receiver circuitry to receive from the local storage device a first selected replacement video advertisement from which the receiver circuitry generates a replacement baseband video signal and transmits the replacement baseband video signal to the display.

Closed loop addressable advertising system and method of operation

A video signal is processed to generate one or more signatures associated with a broadcast program to be recorded by a recording device. The signatures are then processed to determine an actual start time and end time of the desired broadcast program, such that the program can be properly recorded despite delays or other changes in a pre-scheduled broadcast time of the program. One or more of the extracted signatures may be based at least in part on, e.g., a keyframe similarity measure, a histogram, one or more detected commercials, a transcript, a program logo or other detected object, detected text, and a sign-on or sign-off of the desired program. Other types of signatures can also be used.
