Set-top box that provides video data stream to a display device based on selection between recorded video signal received from the digital video recorder and a real-time video signal

摘要

A video system for presenting content from a content provider to a user includes a tuner to select a program from a plurality of programs. The tuner outputs the selected program at an analog output when the selected program is represented by an analog signal. An analog output port is coupled to the analog output of the tuner, and is configured to be connectable to a storage device to record the selected program represented by an analog signal. An analog signal processing circuit is coupled to the analog output of the tuner to receive the analog signal representing the selected program from the tuner and to generate a digital representation of the analog signal. A first interface module is configured to be connectable to the storage device to receive recorded programs from the storage device. An overlay module is coupled to the analog signal processing circuit and to the first interface module. The overlay module selectively overlays information to a program received from one of the analog signal processing circuit and the first interface module.
