A plurality of video signals V21, V22 are processed 201 to provide separate video signals V23, V25 and audio signals V24, V26. The video signals are synthesized in image synthesizer 203 and recorded onto recording medium (eg magnetic tape) 205, whilst the audio signals are convened into a single audio signal in audio synthesizer 204 before recording. On play back picture control selector processes the reproduced video signal and may produce a plurality of picture-in-picture or split screen effects or display one of the input video signals (figs 3a to 3e) via video output synthesizer 208. Audio control selector 207 may output any of the reproduced audio signals. <IMAGE> |
