Abstract:
A video image processing apparatus outputs encoded video data which has been hierarchically encoded to a reproducing apparatus connected thereto in a communicatable manner. The video image processing apparatus includes a conversion unit configured to, if a high-resolution layer with a resolution equal to or greater than a base layer and a field of view wider than the base layer exists, perform resolution conversion processing to render video data corresponding to the high-resolution layer at least equal to or less than the display resolution, a coding unit configured to perform hierarchical coding on video data corresponding to the high-resolution layer subjected to resolution conversion processing by the conversion unit, and video data corresponding to each of the plurality of resolution layers other than the high-resolution layer.
