Abstract: The present disclosure relates to an information processing apparatus and an information processing method that are capable of reproducing content on the basis of an edit list in the case where the reproduction start time of content contained in a file in the MP4 Fragmented Movie format is later than the reproduction start time in a movie time scale. An edit list generation unit registers a top position of content as a reproduction start position of the content and a predetermined value as a reproduction time duration of the content in an edit list when a reproduction start time of the content is later than a reproduction start time of the content on a movie time scale, the edit list associating the reproduction start position of the content with the reproduction time duration of the content reproduced from the reproduction start position. The present disclosure is applicable to a file generation apparatus that generates a Fragmented MP4 file, for example.

Abstract: There is provided a generation device, an identification information generation method, a reproduction device, and an image reproduction method capable of identifying a packing scheme. Stereo packing identification information for identifying a scheme of packing is generated with regard to a plurality of region images of a celestial sphere image packed in a packed frame. In a case in which packing is performed by one of a plurality of packing schemes, stereo packing identification information indicating a packing method can be generated, a projected frame can be generated easily on the basis of the identification information, and the projected frame can be rendered. The present technology can be applied to a case in which a celestial sphere stereoscopic image is transmitted to be reproduced on a reception side.
