System and method of network-linked digital terrestrial television broadcasting
First Claim
1. A system of network-linked digital terrestrial television broadcasting, comprising:
- a broadcast reception means for receiving a digital broadcast to output broadcast data;
a communication means for performing wireless communication with a communication network;
an error detection means for detecting a bit error rate of the broadcast data received by the broadcast reception means; and
an instruction means for instructing a transmission operation of the communication means to stop when the bit error rate of the broadcast data detected by the error detection means is equal to or higher than a predetermined threshold while the communication means performs the transmission operation.

Abstract
In a cellular phone terminal, a bit error rate measurement section measures a bit error rate of broadcast data received by a broadcast reception section for receiving a digital broadcast to output broadcast data while a transmission operation of a communication transmission section 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 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.
