Abstract

In a portable terminal apparatus, a CPU determines receiving condition of broadcast data received by a television broadcast receiving unit, while recording the received data, and records information indicating receiving condition according to the determination result. The CPU obtains information indicating recording condition of the recorded broadcast data based on information indicating receiving condition, and displays the obtained information on a main display unit. Specifically, the CPU sequentially receives ime stamps synchronous with broadcast data while receiving and recording the broadcast data, and records them in time series as information indicating receiving condition. The CPU determines whether time stamps recorded in time series are temporally continuous, and specifies any error portion where the recorded broadcast data has not been received normally, according to the determination result. The CPU displays a bar chart showing distribution of error portions in the total broadcast data recorded, as information indicating recording condition.
