1. A television receiver, comprisinga tuner for receiving a television video signal;
- data storage means including a data storage unit for storing the video signal received by the tuner, a writing pointer for time-sequentially writing the video signal into the data storage unit and a reading pointer for reading the stored video signal;
select means for selecting and outputting one of the reproduced video signal output from the data storage means and the video signal received by the tuner; and
control means for controlling the data storage means and the select means in response to an external input signal,wherein, when a writing command signal is input as the external input signal, the writing pointer in the data storage means starts writing, and when a reproduction command signal is input as the external input signal, the reading pointer in the data storage means starts reading, and the select means selects and outputs the reproduced video signal from the data storage means, andwherein, when the reproduction command signal is input, the reading pointer reads the video signal at a speed higher than the writing speed of the writing pointer until the address of the reading pointer meets the address of the writing pointer, and when the address of the reading pointer meets the address of the writing pointer, the select means selects an output from the tuner.
