Picture producing apparatus

Claim 1

A picture producing apparatus comprising: a first central processing unit for receiving an information which is transmitted and comprises a series of packs of information, for arranging each pack into a predetermined format, and for performing an error detection and an error correction with respect to each pack to obtain a picture information and writing the picture information into a first memory; a second central processing unit for decoding control data of the picture information stored in said first memory and writing picture data of the picture information into a second memory; picture data read-out means for successively reading out the picture data stored in said second memory; timing generator means for producing clock signals for said first and second central processing units and said picture data read-out means, said clock signals being representative of first and second operation time periods which are mutually exclusive; selector means responsive to the clock signal for coupling said first central processing unit to said first memory and coupling said picture data read-out means to said second memory exclusively in the first operation time period and for coupling said second central processing unit to said first and second memories exclusively in the second operation time period so that said second central processing unit performs the decoding and writing with respect to a first pack of said series of pack while said first central processing unit performs the error detection and the error correction with respect to a second pack following said first pack and receives and arranges a third pack following said second pack; color converting means for converting the picture data read out by said picture data read-out menas into color data; and digital-to-analog converter means for converting the color data into an analog video signal.
