Patent ID: 10432989

Abstract:
The present technology relates to a transmission apparatus, a transmission method, a reception apparatus, a receiving method, and a program that enable prompt data delivery. An LCT packet including a portion which is data including part of a fragment; and an LCT header is delivered. The fragment includes a moof and an mdat including an mdat header and a sample group. The moof includes BaseMediaDecodeTime representing a presentation time of a first sample of the mdat. The LCT header includes a sequence number representing a position of the fragment; a version representing a position of the part of the fragment in the fragment; an NTP time corresponding to the BaseMediaDecodeTime; sample count start information representing a position of a first sample of the part of the fragment from a first sample of the fragment; and a moof subset that is at least part of the moof. The present technology can be applied to, for example, a case of multicast-delivering content.
