Title:
DEVICE AND METHOD FOR MONITORING DATA BROADCASTING
Document Type and Number:
Japanese Patent JP3487233
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To directly set a PID and to easily cope with even a different data format by constituting a device for monitoring data broadcasting, of a data receiving board and a data monitoring part for predetermining PID to prescribe an elementary which requires monitoring, checking the CRC error of transmission data from the data reception board and the continuity of data and dumping data.
SOLUTION: A data broadcasting monitor device 6 receives TS(transmission) data from a transmitting unit 20 by a data receiving port 4, buffers TS data in a buffer memory part 3, where only PID of the elementary which requires monitoring is filtered by using a PID filtering part 2, and transmits buffered TS data to a data monitoring part 5 with a PCI interface 7. The data monitoring part 5 checks the CRC error of received TS data or the continuity of TS data, monitors whether TS data are normally transmitted or not and also sets PID in the PID filtering part 2.
