Abstract

A digital broadcasting system is obtained having simple facilities and circuit structure and capable of efficiently transmitting and receiving synchronized pictures and displaying them without applying a synchronizing process thereto. According to the digital broadcasting system, picture signals respectively for the light eye and the left eye obtained from two synchronously operated cameras (13a, 13b) are converted to a noninterlace frame signal (picture data) by a frame memory unit (20) of the transmitting end. The picture data is compressed and modulated, and then transmitted to a communication satellite (8) over a transmission line of one channel. A transmission signal supplied from the communication satellite (8) is demodulated and decoded, and then converted to picture signals for the right and left eyes by a frame memory unit (21) of the receiving end, and the converted signals are displayed on a stereoscopic display monitor (12) in a stereoscopic manner.

Claims2

Dependent claims

A digital broadcasting system, comprising:

picture processing means for multiplexing a field picture signal for the right eye of an interlace system and a field picture signal for the left eye of an interface system synchronized with each other in association with every corresponding even number field and every corresponding odd number field to generate a frame picture signal of one channel of non-interlace system, said picture processing means arranging a picture corresponding said field picture signal for the right eye and a picture corresponding said field picture signal for the left eye respectively into regions formed by vertically dividing a picture corresponding said frame picture signal of one channel;
transmission means for compressing, modulating and transmitting said frame picture signal;
reception means for receiving, demodulating and expanding said transmitted frame picture signal;
and
picture signal reproducing means for receiving said demodulated and expanded frame picture signal and reproducing said field picture signal for the right eye and said field picture signal for the left eye.
