Abstract

An apparatus and a method are provided which make it possible to allow a reception apparatus to execute a cache process in a unit of an application or in a unit of a presentation unit thereby to make it possible to achieve an application execution process of high completeness. The reception apparatus receives, from a transmission apparatus, signaling data in which an application size that is a data size of an application, application link information, and a data size of each of presentation units (PUs) that are application components are recorded. The reception apparatus compares a cache size and the data size of each of the applications and PUs with each other, determines cacheable applications or PUs as cache target data, and executes a cache process in a unit of an application or a PU.

Dependent claims

A reception apparatus, comprising:

a communication section configured to receive first signaling data in which an application size that is a data size of each application and application link information that is link information between the applications are recorded;
and
a data processing section configured to compare a cache size that is a data size capable of being stored in a storage section of the own apparatus and a data size, acquired from the first signaling data, of each of the applications that have a link relationship with each other to determine one or more cacheable applications as cache target applications and executes a cache process in a unit of an application.
