Abstract: The present disclosure relates to a communication device, a communication method, and a program for offering adaptability to a wider variety of applications and enhancing reliability of communications. With a CCI protocol implemented as an upper layer, a physical layer transmits and receives data including an extended header and an extended footer to and from another communication device. A CCI-FS processing section compares a Desination ID included in the extended header with an ID (Source ID) given to the communication device, and determines whether or not the data is for accessing the communication device. The physical layer is MIPI A-PHY that has an asymmetrical upper layer of a point-to-point topology and is designed to allow high-speed data transmission, control data, and electric power to share one physical wire. The present technology is applicable to a communication system that is used for connection in an in-vehicle camera, for example.

Abstract: Communication devices and systems are disclosed. In one example, a communication device is configured to communicate with a communication partner device in accordance with a protocol including a first operation and a second operation. The first operation includes identification information of the communication partner device, write-instructing information, identification information of a first storage unit of the communication partner device, and data to be written in the first storage unit. The second operation follows the first operation and includes identification information of the communication partner device, write-instructing information, identification information of a second storage unit of the communication partner device, information indicating a number of the protocols, and a cyclic redundancy check (CRC) code used to detect an error in the protocol. The second storage unit is configured to store the CRC code and the information indicating the number of the protocols.

Abstract: Provided is a technique for managing advertising displayed on digital signage. An advertising management server causes a mobile display medium having an electronic signboard to display one or more advertisements, acquires positional information about the mobile display medium, receives, from a mobile communication terminal having a photograph function, a photograph image of the advertisement displayed on the mobile display medium and positional information about a position where the photograph image was taken, and grants predetermined payment data for visual recognition of the advertisement by a user of the mobile communication terminal, to a manager of the mobile display medium and the user of the mobile communication terminal, when the visual recognition of the advertisement by the user of the mobile communication terminal is confirmed based on the positional information about the mobile display medium and positional information about the mobile communication terminal.
