x1 is the video/(possibly changing) visual content to/of recording/broadcast x2 displayed/produced by medium/device x3
Differs from tivni in that a given broadcast may have multiple sensory components, but this one deals only with the visual ones; x2 may also not be televized/broadcasted (it could even be a static painting). It differs from viska in that no observer is necessary; a recording inherently has or does not have visual content. See also: snavi.
