Abstract
An apparatus and method are provided for indicating an error of a transport packet in an audio and video communication system. The method includes receiving a frame including a transport packet, attempting Forward Error Correction (FEC) on the frame, and setting a value of an error indicating field in the transport packet according to a result of the FEC. The error indicating field includes at least one of a first flag indicating a presence or absence of an error in the transport packet, a second flag indicating a success or failure of the FEC, and a third flag indicating detection or non-detection of a Cyclic Redundancy Check (CRC).
