Abstract

The video data contained in the digital broadcasting received by a receiver are transmitted to a printer at high speed and at low cost. A receiver (STB 30) for receiving digital broadcasting, a display 31 for displaying the images of the digital broadcasting received by the STB 30 and a printer 32 for printing images contained in the digital broadcasting received by the STB 30 are connected to each other by way of a first signal transmission means adapted to transmit digital signals. The printer 32 obtain video data from the receiver 30 by way of the first signal transmission means.

Claims

1-49. -49. (canceled)

50. A digital broadcasting reception system comprising a receiver for receiving digital broadcasting, a display for displaying the images of the digital broadcasting received by said receiver and a printer for printing images contained in the digital broadcasting received by said receiver;

said receiver, said display and said printer being connected to each other by way of a first signal transmission means for transmitting digital signals;

said receiver having;

a reception means for receiving digital broadcasting,

an imaging means for generating video data by performing a predetermined imaging operation according to the received signals of digital broadcasting,

an output means for transmitting the video data generated by said imaging means by way of said first signal transmission means to said display and to said printer, and

a code data generating means for generating code data containing service information and/or character information by performing a certain processing operation according to the signals of the digital broadcasting received by said reception means;

said printer having;

a reception means for receiving video data transmitted by said first signal transmission means,

a printing means for printing the images of the video data received by said reception means,

a code data extracting means for extracting the service information and/or the character information out of the code data received by said transmission/reception means, and

a synthesizing means for synthesizing the service information and/or the character information extracted by said code data extracting means and generating synthesized images;

said receiver and said printer are connected to each other by way of a second signal transmission means showing a data transmission rate lower than said first signal transmission means;
