Abstract: To realize processing for switching a reproduction state from broadcast data to network data and resuming the reproduction of the original broadcast data. A browser (241) acquires, via a network, an XML-AIT having a content equivalent to a broadcast AIT defining a life cycle of a broadcast application while a VoD content is reproduced after being switched from the broadcast application. The browser (241) manages the broadcast application based on the XML-AIT and resumes the reception of the broadcast application after the reproduction of the VoD content is ended. With this structure, processing of separating two transport streams at the same time becomes unnecessary, and one demultiplexer (23) only needs to be provided.

Abstract: Transmission frequency information in units of component, the component being a data element contained in one broadcast delivery service and allowed for independent delivery, is supplied to a user terminal to execute reception setting in units of component. A data transmission device transmits, to the user terminal, metadata recording transmission frequency information in units of component that is constituent data of a broadcast delivery service and corresponds to a data element allowed for independent delivery to the user terminal, such as units of component of image data having a particular resolution, audio data or subtitle data in a particular language, or other types of data. The user terminal corresponding to a receiving device executes a setting process for setting a reception frequency allowing reception of a component to be received based on transmission frequency information recorded in units of component in the metadata received from the data transmission device.

Abstract: [Object] To provide a communication device and communication method that are capable of both efficiently utilizing wireless communication resources and reducing electric power consumption in a frame exchange period with a communication device different from an own device.[Solution] A communication device includes a communication unit configured to receive a first frame from a first communication device, the first frame being addressed to a second communication device that is different from the own device. The first frame includes information indicating a frame exchange period and information on whether the frame exchange period is changed. In addition, a communication device includes a communication unit configured to transmit a first frame that includes information indicating a frame exchange period and information on whether the frame exchange period is changed.

Abstract: Data communication is performed appropriately.An information processing apparatus includes a control unit. In a case of transmitting data by using wireless communication, the control unit performs control of performing transmission while including determination information with which a device in a transmission destination of the data determines in a data link layer whether to pass the data to a higher layer of the data link layer into the data. Also, in a case of receiving data by using wireless communication, the control unit performs control of determining whether to pass the data to a higher layer of a data link layer on the basis of information included in the data (determination information that can be grasped in data link layer).
