<p>An apparatus, for stereoscopic (3DTV) video encoding, comprises: a depth data generator determining ranging information for a set of views; means to determine a unit (e.g. a subset of views, a set of pictures within each view or a spatial region within a picture) associated with the set of views; a depth data validity determiner determining the validity of ranging information for the unit; and an indicator inserter to generate at least one indicator based on ranging information validity. Also claimed is a method comprising receiving a signal comprising at least one indicator based on ranging information validity, and controlling ranging information utilisation based on this indicator. Determining the validity of ranging information may comprise: determining ranging information is not output from decoding; ranging information being marked unavailable or invalid; hole filling employment; ranging information not to be used for depth-image based rendering; determining that ranging information can be replaced with a depth estimation algorithm output from decoded texture views; ranging information being partially unavailable / invalid with respect to a first or second portion of views; ranging information being (un)available / (in)valid for first or second processing operations; the quality of ranging information being below a threshold, etc.</p> |
