TRANSMISSION DEVICE, RECEPTION DEVICE, AND DATA PROCESSING METHOD

摘要

The present invention realizes a configuration that enables a reception device to select an acquisition object on the basis of priority information when the delivery times of transmitted contents via different channels overlap. A transmission device sets, for each of transmitted contents, service selection priority information (Service Selection Priority) utilizable in the reception device as a cache processing priority determination criterion, and transmits the service selection priority information to the reception device. The service selection priority information is utilized as priority information that enables the reception device to select a content having a high value of service selection priority information as an object to be cached when the delivery times of transmitted contents via different channels overlap.
