Abstract: There is provided an information processing apparatus and an information processing method that can enhance the image quality while, at the same time, reducing increase in client's throughput. Image data of a plurality of projection directions is generated by projecting 3D data in a plurality of projection directions and converting the 3D data into two-dimensional data, and projection direction information indicating the projection direction of each piece of the image data is generated as projection metadata. Further, the projection direction information includes additional projection direction identification information that indicates that the image data has been generated by projection in additional projection directions. The present technology is applicable, for example, to a data generation apparatus that generates data for delivering a point cloud.

Abstract: There is provided a delivery apparatus, a delivery method, and a program that are capable of providing live delivery with lower delay. Based on a URL specified by a request from a client regarded as a destination to which a content is live-delivered by using MPEG-DASH, DASH segments included in content are delivered. An extended function of independently specifying a duration of DASH segments and a placement of an SAP is used to define the URL so as to make a request for a whole of a segment sequence including a series of DASH segments consecutively arranged. Further, the URL is defined so as to make a request for a predetermined number of DASH segments from a random access point, including a random-accessible DASH segment and subsequent DASH segments in the same segment sequence. The present technology is applicable, for example, to a content delivery system that provides live delivery by using MPEG-DASH.
