Transmitting device, transmitting method, receiving device, and receiving method

Abstract

A receiving side can perform interactive processing based on information of an object. Image data is coded to obtain a video stream having coded image data. The video stream is transmitted in a state of being added with information of an object detected on the basis of image data. For example, information of an object includes coded data obtained by coding one-bit data showing a shape of the object, information of a region that is a rectangular area enclosing the object, display priority information of the region, text information that explains the object, and the like. The receiving side can acquire information of an object without the need of detecting an object by processing image data, and without depending on its own performance, and is allowed to perform interactive processing based on information of an object in an excellent manner.
