Communication terminal device and method for its operation with digital reception of broadcasting using bit error detection to control a broadcast shutdown in the terminal device

摘要

In a cellular phone terminal (100), a bit error rate measurement section (103) measures a bit error rate of broadcast data received by a broadcast reception section (102) for receiving a digital broadcast to output broadcast data while a transmission operation of a communication transmission section (106) for wirelessly communicating with a broadcasting communication network is performed. When the measured bit error rate is equal to or higher than a predetermined threshold, stopping of the transmission operation of the communication transmission section (106) is instructed. Thus, a failure such as interruption of television broadcasting reproduction can preliminarily be prevented by avoiding error occurrence in reception of the 1 segment broadcasting service due to an influence of a transmission electric wave in data communication. As a result, stable reception of the 1 segment broadcasting service can be executed.
