An information processing device for obtaining content is provided. The information processing device includes circuitry configured to receive audio/video (AV) content via a broadcast signal. The circuitry is configured to receive from a provider of the AV content, provider-side preference, demographic or interest (PDI) information. The provider-side PDI information is associated with further content. The circuitry is configured to obtain user-side PDI information, and determine whether the provider-side PDI information and the user-side PDI information match. The circuitry is configured to obtain the further content when the provider-side PDI information and the user-side PDI information are determined to match, including calling at least one application programming interface (API).
