RECEPTION DEVICE, TRANSMISSION DEVICE, AND DATA PROCESSING METHOD

Provided are a device and a method which are capable of performing selection acquisition and utilization processes for a service worker (SW) that performs data management optimized for each reception device. It is possible to selectively acquire a service worker (SW) of a specific class from service workers (SWs) corresponding to a plurality of classes which are data management programs used in a reception device and have different data managementtypes. For example, use of a service worker (SW) corresponding to a class selected according to an application use state in a reception device is implemented. A reception device acquires access information of a service worker (SW) of a specific class using signaling data in which a token used for efficiently searching for the access information of the service worker (SW) of the specific class is recorded, and acquires the service worker (SW) .
