DEVICE FOR RECEIVING HD(HIGH DEFINITION) DIGITAL BROADCASTING PROGRAM BY USING USB2.0, ENABLING USER TO WATCHING HD DIGITAL TV ON PC WITHOUT MOUNTING CARD
Purpose: a device, for by using a USB2.0 device receives HD (high-resolution) digital broadcast program, is provided to and effectively transmits from the HD transport streams that a digital tuner generates to a USB2.0 device controller receives the HD transport streams of transmission in a PC, so that one HD digital TV of viewing, not will be installed a piece of card. Construction: hardware connection is performed as follows. The transport stream synchronised clock exported from a digital tuner (10) is connected to a USB2.One FIFO of 0 device controller (12) records unit. The transport stream data generated from digital tuner (10) is connected to USB2.The first in first out of 0 device controller (12) inputs. FIFO address parts are fixed to and endpoint is equivalent. The connection of one software is performed as follows. One of FIFO (11) selection endpoints of one subordinate, setting volume-is in comfortable and asynchronous system. When FIFO (11) is full, data are to be automatically transferred to selected endpoint.
