Abstract: A communication apparatus, method and program that accommodate diverse usage are disclosed. In one example, a packet header is generated according to a CSI-2 standard. The packet header includes setting information of conditions set for data to be transmitted in a packet is placed. An extended header is also generated, into which the setting information is to be placed separately from the packet header. Then, into an unused region defined as a region that is not used in the existing CSI-2 standard with respect to a data type that is the setting information indicative of a type of the data to be transmitted in the packet, extension mode setting information indicative of whether or not an extension mode using the extended header is used is placed. The disclosed technology can be applied, for example, in a mobile device or in an in-vehicle camera.

Abstract: This disclosure relates to a communicating apparatus, a communication method, a program, and a communication system that each enable execution of more reliable communication.
A communicating apparatus includes a transmitting and receiving part that executes transmission and reception of signals with at least one or more other communicating apparatuses through a data signal line and a clock signal line, and an error avoiding part that, in a state where a communication system configured to be able to execute communication through a bus already operates, executes a process of avoiding occurrence of any error occurring when a communicating apparatus is additionally connected to the communication system. This technique is applicable to, for example, a bus IF.

Abstract: Communication devices and systems with low power consumption and high speed are disclosed. In one example, a communication device includes: a state switching control circuit that controls switching between a first state in which synchronization is established with a communication partner device, a second state in which communication is started, a third state in which the communication is intermittently stopped, and a fourth state in which the communication is stopped for a longer period than the third state. A first communication control unit transmits a first signal during a first signal section in the fourth state, and a second communication control unit transmits a third signal synchronized with a received second signal to the communication partner device. When the second communication control unit transmits the third signal, the state switching control circuit causes the communication device to transition from the fourth state to the first state.
