Abstract: The present disclosure relates to an image processing apparatus and an image processing method which enable reproduction of content data to be more reliably controlled. For example, with respect to a segment with which reproduction control for stream data obtained by encoding image data is carried out, a verification code of the stream data of the segment is produced, and the verification code produced is added to the stream data of the segment. In addition, for example, with respect to a segment with which reproduction control for stream data obtained by encoding image data is carried out, a verification code of the stream data of the segment is produced, the verification code produced and a verification code added to the stream data of the segment are compared with each other, and the reproduction of the stream data of the segment, a following segment, or both of them is controlled in response to agreement or disagreement between the verification codes. The present disclosure, for example, can be applied to an image producing apparatus, an image encoding apparatus, an image decoding apparatus or the like.

Abstract: The present disclosure relates to a reproduction device and a reproduction method, and a file generation device and a file generation method, which enable acquisition of a video stream having an optimum bit rate when acquiring an audio stream encoded by a lossless compression technique and a video stream. A segment file acquisition unit acquires an audio stream encoded by a lossless DSD technique before a video stream corresponding to the audio stream and detects a bit rate of the audio stream. A selection unit selects the video stream to be acquired from a plurality of the video streams having different bit rates, on the basis of the bit rate detected by the segment file acquisition unit. The present disclosure can be applied to, for example, a moving image reproduction terminal or the like.

Abstract: The present disclosure relates to a file generation device and a method, and a content playback device, enabling efficient access to arbitrary subsamples within a sample. As indicated by grouping_type=‘sgss’, a subsample sample group (entry) structure is used as an sgpd. mha1 is identification information indicating 3d audio. As indicated by entry_count=3, the sgpd includes three entries. The three entries are defined to be mha1 0, mha1 1, and mha1 2. To assign these meanings of the sgpd to levels, the sgpd entries are linked to leva entries in index order. The present disclosure may be applied to a content playback system equipped with a content server and a content playback device, for example.
