Transmission apparatus, reception apparatus, and data processing method
A configuration is realized that receives advertisements highly likely to be viewed and ensures enhanced likelihood for reproduction on a reception apparatus by controlling a transmission order of advertisements that can be selected and output. A transmission apparatus determines a transmission order of a plurality of pieces of advertisement content that can be selected and output during an advertisement output time of a given duration on a reception apparatus and sends the pieces of content. The transmission apparatus arranges the transmission time of content highly likely to be viewed closest to the advertisement output time and arranges the transmission time of content unlikely to be viewed before the transmission time of content highly likely to be viewed. Further, the transmission apparatus sends delivery priority information (Delivery Priority) specified for each of the plurality of pieces of advertisement content to the reception apparatus so that the reception apparatus can decide whether caching is required based on priority information.
