摘要： The present invention enables a receiving side to easily recognize a high-quality format corresponding to encoded image data included in an extended video stream. Two video streams including a basic video stream including encoded image data of basic format image data, and an extended video stream including encoded image data of high-quality format image data of one type selected from a plurality of types are generated. A container of a predetermined format including the basic video stream and the extended video stream is transmitted. Information indicating a high-quality format corresponding to the encoded image data included in the extended video stream is inserted into the extended video stream and/or the container.

摘要： To reduce a processing load at a reception side in a case where a plurality kinds of audio data items are transmitted.
A container in a predetermined format having a predetermined number of audio streams including coded data items of a plurality of groups is transmitted. For example, the coded data items of the plurality of groups include either or both of channel coded data items and object coded data items. Attribute information indicating respective attributes of the coded data items of the plurality of groups is inserted into a layer of the container and/or a layer of an audio stream. For example, stream correspondence relation information indicating which audio stream includes each of the coded data items of the plurality of groups is further inserted.

摘要： The present invention is designed to easily prevent an occurrence of a display mute in a case of switching services.
An image encoding unit generates a video stream by encoding image data of each picture that constitutes moving image data. A transmission unit transmits a container in a predetermined format that continuously includes a first video stream and a second video stream generated in the image encoding unit. The first video stream and the second video stream are composed of first to Mth streams out of first to Nth streams (M ≤ N). The transmission unit applies a fixed identifier to the respective first to Nth streams.

摘要： The present invention allows favorable decoding on a reception side.
Image data of pictures constituting moving image data is encoded to generate a video stream (encoded stream). In this case, the image data of the pictures constituting the moving image data is classified into a plurality of levels and encoded to generate a video stream having the image data of the pictures at the respective levels. Hierarchical composition is equalized between the low-level side and the high-level side, and corresponding pictures on the low-level side and the high-level side are combined into one set and are sequentially encoded. This allows the reception side to decode the encoded image data of the pictures on the low-level side and the high-level side with a smaller buffer size and a reduced decoding delay.

摘要： A predetermined number of pieces of high-quality format image data are successfully transmitted together with basic format image data. A basic video stream including encoded image data of basic format image data and an extended video stream including encoded image data of each of a predetermined number of pieces of high-quality format image data are generated, or a video stream including encoded image data of basic format image data and encoded image data of each of a predetermined number of pieces of high-quality format image data is generated. A container of a predetermined format including the generated video stream is transmitted. Identification information identifying a corresponding format is inserted into the encoded image data of the basic format image data and each of a predetermined number of pieces of high-quality format image data.

摘要： To enable a set of media access control to be favorably performed on the reception side.
A container having a predetermined format is transmitted, the container including a media stream. A predetermined number of pieces of media access information associated for the set of media access control, are sequentially inserted into a layer of the media stream or a layer of the container. For example, the media access information includes identification information for making a distinction from different media access information and identification information for making an association with the different media access information.

摘要： A process of an audio stream on a receiving side is facilitated.
Encoding processing is performed on audio data and an audio stream in which an audio frame including audio compression data is continuously arranged is generated. Tag information indicating that the audio compression data of a predetermined sound unit is included is inserted into the audio frame including the audio compression data of the predetermined sound unit. A container stream of a predetermined format including the audio stream into which the tag information is inserted is transmitted.

摘要： A material of image data subjected to a mixing process is enabled to be satisfactorily handled on a reception side, for example, when the material is transmitted.
A packet is transmitted, which includes, as payload data, divided image data obtained by dividing predetermined frame frequency image data into a predetermined number for each frame. The predetermined frame frequency image data is subjected to a mixing process selectively using preceding and/or subsequent frame image data for each frame. Metadata including information related to the mixing process is further transmitted in association with the image data of each frame. For example, the metadata is inserted into a payload header of a packet including at least a beginning of the image data of each frame and is transmitted. Moreover, for example, the metadata is transmitted by a metadata-only packet associated with the packet including the image data of each frame.

摘要： In a case where a plurality of transmission video data having predetermined opto-electrical transfer characteristics are switched therebetween and transmitted, processes for obtaining image data for display from the transmission video data are achieved to be appropriately performed at a receiver side.
A video stream is obtained by switching between a plurality of kinds of transmission video data having predetermined opto-electrical transfer characteristics and encoding the resulting transmission video data. A container in a predetermined format containing the video stream is transmitted. Identification information representing the kind of transmission video data included in the video stream contained in the container is inserted in the container, such that the identification information indicates the kind of transmission video data resulting from switching, from a timing that is a predetermined amount of time or longer before the switching timing.

摘要： To enable a reception side to perform a favorable decoding process commensurate with its decoding capability. Image data of each of pictures which constitute dynamic image data is classified into a plurality of layers, image data of each of the classified layers is encoded, and a video stream having the encoded image data of the pictures of each of the layers is generated. A container in a predetermined format which includes the generated video stream is transmitted. Decoding timing information, which has been set in a manner that a higher layer has a shorter decoding time interval of the encoded image data of each of the pictures, is added to the encoded image data of the pictures of each of the layers.
