<p><P>PROBLEM TO BE SOLVED: To provide a digital microwave receiver capable of outputting a TS (Transport Stream) signal under stable reception synchronization even when the TS signal is directly subjected to digital modulation and the resulting TS signal is transmitted without being converted into a transmission frame configuration. <P>SOLUTION: The digital microwave receiver is provided with: a B8 detection circuit 211 for detecting a synchronous byte B8 from the TS signal; a synchronous monitor circuit 219 for confirming the position of a packet of the TS signal 232; a B8 period counter circuit 212 for counting a B8 period; an OR circuit 214 for confirming the phase timing of a B8 detection pulse 204; a B8 synchronization monitor counter 216 that counts the mismatching between a B8 period pulse 205 and a counter load pulse 207 and outputting a B8 out-of-synchronism detection pulse 208 when the count reaches a prescribed count; a packet start pulse generating circuit 218 for outputting a packet start pulse 231; and an OR circuit 217 for detecting the out-of-synchronism to output a reset pulse 236 to the B8 period counter circuit 212. <P>COPYRIGHT: (C)2004,JPO</p> |
