Method of treating television picture signals and wide-band data signals by modulating the color carrier signal

Playback apparatus for television picture signals and measured data signals synchroniously recorded in frequency multiplexed form on a record medium, the apparatus comprising

• playback means for playback of said record medium,
• filter means connected to said playback means to receive a playback signal therefrom and adapted to separate said playback signal into television picture signals and data signals
• video-monitor means connected to said filter means and adapted to receive and display said television picture signals therefrom,
• bit-synchronizer means connected to said filter means to receive said data signals therefrom,
• data synchronization means connected to said bit-synchronizer means to receive synchronized data signals therefrom,
• serial to parallel converter means connected to said data synchronization means and adapted to convert serial signals received therefrom to parallel form,
• temporary store means connected to said serial to parallel converter means and adapted to temporarily store signals received therefrom, and
• decoder means connected to said temporary store means and adapted to decode signals received therefrom.

A method of treating television color picture signals including a color carrier signal and wide-band data signals representing measured data associated with the subject of said television picture signals on a time synchronous basis, comprising the steps of:

• receiving said data signals continuously,
• converting said received data signals to digital form,
• temporarily storing said data signals in digital form,
• multiplexing together said digital data signals and television picture signals by at least one of time and frequency multiplexing techniques, and
• recording the multiplexed signals on a recording medium in video recorder means,
• said measured data being recorded by amplitude modulation of said color carrier signal.

Apparatus for synchronously recording television picture signals and measured wide-band data signals comprising

• multiplexer means,
• means supplying wide band measured data signals to said multiplexer means,
• signal holding means connected to said multiplexer means and adapted to receive and hold data signals therefrom,
• analogue to digital converter means connected to said signal holding means and adapted to convert signals received therefrom into digital form,
• store means connected to said analogue to digital converter means and adapted to store digital data signals received therefrom,
• a source of television picture signals,
• mixer means connected to said store means and to said source and adapted to multiplex together digital data signals and television signals received respectively therefrom,
• video-recorder means connected to said mixer means and adapted to record multiplexed signals received therefrom on a record medium therein and, parallel to serial converter means connected between said store means and said mixer means and adapted to convert parallel signals received from said store means to serial form for transmission to said mixer means.
