Abstract
Convergence systems, or PC-TV systems, provide the combined benefits of a computer system and a television. These systems typically include audio/video recorders, such as VCRs, for recording programs, as well as an electronic program guide (EPG) for presenting program information. The present invention provides methods and devices for detecting specific signals or markers associated with a program or channel signal, and then enabling a recording device or an EPG to perform an act, such as recording a program, based upon the detected signals or markers. In a preferred embodiment, the system receives a channel signal, detects a program start or stop marker within the signal, and controls the EPG or the recording device to perform acts corresponding to the detection of a start or stop instruction.
