DIGITAL TV SYSTEM BY COMPUTER DEVICE CONNECTED THROUGH HIGH-SPEED SERIAL BUS, ESPECIALLY IN RELATION TO TRANSMITTING VIDEO AND VOICE DATA OF TV SET THROUGH A HIGH-SPEED SERIAL BUS, AND CONTROLLING THE DATA ACCORDING TO A CONTROL PROGRAMMED PROCESS TO REALIZE A DIGITAL TV

摘要

PURPOSE: A digital TV system by a computer device connected through a high-speed serial bus is provided to transmit video and voice data of a TV set through a high-speed serial bus, and to control the transmitted data according to a control programmed process to realize a digital TV, consequently inconvenience of using another computer card can be resolved. CONSTITUTION: A TV set(10) comprises as follows. A tuner(11) receives a public propagation. A demodulator(13) checks a digital TV broadcast signal, and converts the propagation into TS(Transport Stream)-type digital data. A high-speed serial controller(15) transmits the digital data to a computer device(20). The computer device(20) comprises as follows. A high-speed serial bus driver(21) receives the digital data. A CPU(23) executes the driver(21). A digital AV process controller(30) is executed by the CPU(23) to control video, voice, and information digital data. A high-capacity memory device(25) stores the digital data.
