Abstract

A television and Internet system combine a television receiver and an Internet access subsystem. The system includes a television with the usual subsystems including a tuner, color demodulator and R-G-B video amplifiers, deflection amplifiers and high and low voltage power supply, audio amplifier and on-screen display processor including a vertical blanking interval decoder. The system additionally includes a microprocessor which supports serial communications, RAM, Flash memory and ROM for storing the operating system, Internet communications protocol and Internet browser software, graphics display controller and network interface. The microprocessor decodes Internet addresses encoded and transmitted via the vertical blanking interval and provides direct access to the Internet through the television receiver.

Claims
