Abstract: A transmission method includes generating one or more frames for content transfer using IP (Internet Protocol) packets, and transmitting the one or more generated frames by broadcast. Each of the one or more frames contains a plurality of second transfer units, each of the plurality of second transfer units contains one or more first transfer units, and each of the one or more first transfer units contains at least one of the IP packets. An object IP packet of the IP packets which is stored in a first transfer unit positioned at a head in the one or more frames contains reference clock information that indicates time for reproduction of the content in data structure different from data structure of an MMT (MPEG Media Transport) packet, and header compression processing on the object IP packet is omitted.

Abstract: A transmitting method for transmitting contents using a broadcast wave and a communication path comprises: including content information in application control information when transmitting the contents using both the broadcast wave and the communication path, the content information being information for synchronizing a content transmitted by using the broadcast wave with a content transmitted by using the communication path at a reception side that receives the contents and being related to the content transmitted by using the communication path; and transmitting the application control information by using at least the broadcast wave in the broadcast wave and the communication path. As a result, a contents transmitting method is provided for enabling a quick access to contents through communication when the contents are reproduced by a combination of broadcast and communication on the receiving side.

Abstract: A three-dimensional data encoding method of encoding three-dimensional points includes: calculating a new predicted value as a predicted value, using attribute information items of one or more second three-dimensional points neighboring a first three-dimensional point, and assigning the predicted value to at least one prediction mode among two or more prediction modes, the new predicted value being used for calculating an attribute information item of the first three-dimensional point; selecting one prediction mode from the two or more prediction modes; calculating a prediction residual which is a difference between the attribute information item of the first three-dimensional point and the predicted value of the one prediction mode selected; and generating a bitstream including the one prediction mode and the prediction residual.

Abstract: A three-dimensional data encoding method includes: generating encoded data by encoding third point cloud data that is a combination of first point cloud data and second point cloud data; and generating a bitstream including the encoded data and control information. The encoded data includes a piece of geometry information and pieces of attribute information of each of three-dimensional points included in the third point cloud data. One of the pieces of attribute information includes first information indicating whether a corresponding one of the three-dimensional points belongs to the first point cloud data or the second point cloud data. The control information includes second information indicating, among the pieces of attribute information, a piece of attribute information including the first information.
