Abstract: A technique capable of allowing a reception side to easily select components is provided. A transport stream in which a first transport packet including predetermined components and a second transport packet including signaling information related to the predetermined components are time-division multiplexed is transmitted via a predetermined transport path. Component selection information is inserted in the second transport packet. The component selection information includes information on a selective layer in which static selection is performed, information on a composite layer in which composition is performed, and information on an adaptive layer in which dynamic switching is performed, and these layers being arranged in that order from top to bottom. The acquisition destination information of a component which is a target of adaptive switching among the components selectable in the adaptive layer is information that designates specific information location of a metafile having data stream acquisition information for adaptive streaming.

Abstract: A configuration capable of performing a process of presenting the emergency information to the viewer promptly and reliably is implemented. Middleware of a receiving device that performs a broadcasting content output process receives an emergency information delivery notification transmitted by a transmitting device and generates emergency information event notification data including configuration data of the received emergency information delivery notification. An output data control unit acquires event notification data and executes a process of acquiring or displaying emergency information on the basis of the acquired event notification data. For example, in a case where emergency information overlaid on an image is delivered, application presentation content is deleted in accordance with an event notification, and in the case of signaling emergency information delivery, a process of acquiring and outputting the emergency information promptly is executed.
