摘要： A method and apparatus by which a reception device of a communication system can sense and compensate for an error of a program clock reference (PCR), and can sense and compensate for bit rate variation of transmission data in a transmitted MPEG-2 TS. The method and apparatus compensates for a PCR jitter, or a change in a data bit rate, which may occur in processing an MPEG-2 TS in a reception device of the MPEG-2 TS transmission system, thereby preventing the deterioration of image quality due to the jitter or loss of an input MPEG-2 TS data. The apparatus includes a PAT sensing unit for sensing a PAT from a received MPEG-2 TS, a PMT sensing unit for sensing a PMT based on information provided from the PAT sensing unit, a PCR PID unit for sensing a PCR PID based on information provided from the PMT sensing unit and a PCR data unit for outputting a PCR data based on information provided from the PMT sensing unit and PID information provided from the PCR PID unit. The apparatus also includes a PCR comparison/compensation unit receiving the PCR data from the PCR data unit, comparing the received PCR data with a pre-stored PCR data, and compensating for the pre-stored PCR data, and a data rate comparison/compensation unit for receiving data rate information from the PCR data unit, comparing the received data rate with a pre-stored data rate, and compensating for the pre-stored data rate.

摘要： A wired relay method for using a remote station and an apparatus thereof for a Radio over Fiber (RoF) wired relay system supporting a Time Division Duplexing (TDD) wireless communication service, which shares an Low-Noise Amplifier (LNA) for both uplink and downlink operations. The remote station includes a block for dividing each of a downlink optical signal carrying service data and an optical signal carrying transmission/reception control information of the RoF wired relay system, which are input from a base station, a gain controller for separating an uplink Radio Frequency (RF) signal input from an antenna or a portion of a downlink RF signal output from a High-Power Amplifier (HPA) and for monitoring the strength of the input and output RF signals in order to control a gain of the LNA. A converter mutually converts an optical signal and an RF signal, an amplifier amplifies the converted RF signal, and an RF signal flow controller automatically controls uplink and downlink transmission paths of the amplified RF signal according to a transmission/reception status of the RoF wired relay system.
