Abstract
The present technology relates to a transmission apparatus, a transmission method, a reception apparatus, and a reception method which can easily obtain a mosaic screen.
Metadata of content is distributed, and the metadata is described using an attribute and an attribute value and includes signaling information indicating that a video is a thumbnail video suitable for constituting a mosaic screen, and the attribute indicating information to refer to a file including information to receive content supplied by a service. The present technology can be applied when, for example, content is to be distributed.
