    摘要: The present invention is to realize a proper inner zone layout in a quadruple-layer disk.A test area is provided in the inner zone (inner circumference side area) in each of recording layers. If two test areas closer to the outer circumference, of four test areas, are defined as a first pair and two test areas closer to the inner circumference are defined as a second pair, the test areas of the first pair and the test areas of the second pair are so disposed as to be prevented from overlapping with each other in the layer direction. Two test areas of the first pair have the same consumption direction of the test area, and are so disposed that the areas to be used next hardly overlap with each other in the layer direction. Two test areas of the second pair have the same consumption direction of the test area opposite to the consumption direction of the test area in the first pair, and are so disposed that the areas to be used next hardly overlap with each other in the layer direction.

    摘要: 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).
