[0021]
Here, the recording / reproducing unit 130 preferably includes a semiconductor memory as a readable and writable recording medium for recording still image information, but does not prevent the case where another recording medium is included.
[0022]
The output unit 140 outputs a moving image information obtained by the TV tuner unit 120 and a still image information recorded and reproduced by the recording and reproducing unit 130. The display unit 141 outputs audio information obtained by the TV tuner unit 120. And a speaker section 142 for outputting. The display unit 141 and the speaker unit 142 may be configured to be independent of each other, or may be configured to be integrated with each other.
