<p>PURPOSE:To relieve a load rate of a software by allowing a software processing time of a computer to have a margin, by using a 2 frame/1 block transferring system for collecting two frames to one block and transferring it, and also, detecting a frame which has caused step out of synchronization or a write error in the frame, and preventing it from being transferred to the computer. CONSTITUTION:By a clock signal outputted from a demodulator of a receiving part 1, a storage part 3 collects successively stored frames to two frames, as one block, and outputs it to a computer 4. A transfer inhibiting circuit 5 detects a LOCK 'OFF' signal and a write failure signal at every frame outputted from the receiving part 1 and the storage part 3, and inhibits a frame signal corresponding to a detection failure signal to be sent out to the computer 4 from the storage part 3. In this way, by curtailing once the sending-out inquiry time, the software processing time of the computer is lengthened, and also, the computer 4 calculates only effective frame data, and also, the calculation time is taken long, therefore, the software processing time has the margin and the load rate is relaxed.</p> |
