CIRCUIT FOR CONTROLLING A HIGH-SPEED ADVANCED TELEVISION STANDARD COMMITTEE-MOBILE/HANDHELD BASE BAND FOR CHECKING THE ERRORS FOR AN OUTPUT SIGNAL OF A RADIO FREQUENCY BLOCK

摘要

PURPOSE: A circuit for controlling a high-speed advanced television standard committee-mobile/handheld (ATSC-M/H) base band is provided to reduce an operation burden of a micro control unit (MCU) block for implementing ATSC-M/H technology.;CONSTITUTION: A circuit for controlling an ATSC-M/H base control circuit includes a radio frequency (RF) block (100), an RX FIFO unit (200), an IP/UDP function unit (300), a memory unit (400), and an MCU block (500). The RF block receives and transmits an RF signal inputted by ATSC-M/H technology. The RX FIFO unit receives a signal, which is outputted from the RF block, and changes the signal into a digital value. The RX FIFO unit converts the signal into parallel IP/UDP packet data and outputs the signal. The memory unit stores IP/UDP packet digital data provided from the RX FIFO unit. The IP/UDP function unit deletes data having errors by checking the errors of the data stored in the memory unit. The MCU block receives and processes the IP/UDP packet data stored in the memory unit.;COPYRIGHT KIPO 2013;[Reference numerals] (100) RF block; (200) RX FIFO unit; (300) IP/UDP function unit; (400) Memory unit; (500) MCU block; (AA) Broadcast signal
