FIELD: digital data processing for satellite or ground transmission. SUBSTANCE: device has adaptive decoder for shaping decoded output data from video signal coded for satellite, ground, or cable transmission; adaptive decoder for shaping first decoded output signal as function of code transmission rate chosen from set of data transmission rates; adaptive inverted interlacer for inverted interlacing of first decoded output signals according to inverted interlacing function chosen from set of inverted interlacing functions; output signal processor for processing inverted interlaced output data to provide decoded output data. Device may also incorporate adaptive error decoder for detecting and correcting errors in inverted interlaced output signal that may also evaluate error in decoded output signal. Device is automatically configured to be compatible with coded signal format in response to error evaluation. EFFECT: enhanced code transmission speed, improved validity of output signal. 22 cl
