The present technology relates to a transmission device, a transmission method, a reception device, a reception method, and a transmission-reception device capable of storing a plurality of pieces of data having different bit widths in a payload of one packet and transmitting the data.

A transmission device according to one aspect of the present technology generates a packet used for transmission of data of each line constituting a frame in which data to be transmitted is arranged in a predetermined format by adding, to a payload storing a plurality of types of unit data having different bit widths for each data unit, a header including separation information including an identifier representing that the plurality of types of the unit data is stored in the payload, and transmits the packet. The present technology can be applied to devices that perform SLVS-EC standard communication.

A display apparatus is configured to activate a display control apparatus by transmitting an activating signal to the display control apparatus in response to determining that a start condition is satisfied. In response to receiving the activating signal, the display control apparatus is enabled to transmit a video data corresponding to a video to be displayed in a display in the display apparatus.

A reception apparatus, including circuitry configured to receive a content including at least one of audio content or video content, extract fingerprint information from data of the content, and provide the fingerprint information to a first server via a communication network. The circuitry is further configured to receive control information in response to providing the fingerprint information to the first server.

In a video signal transmission system using fiber optic cable, an improved optical transceiver module (fiber module) having integrated video signal processing capabilities can be used in video signal transmitters for video sources, video signal receivers for display devices, or video switching devices. The improved fiber module has a form factor complying with the Small Form-factor Pluggable standard, and a standard optical fiber connector. In addition to an optical transceiver, the improved fiber modules includes a ¼ inch signal processing chip programmed to perform video signal processing. The mainboard of the video signal transmitter or receiver or the video switching device has additional signal processing chips for processing non-video signals such as audio, data, network, RS-232, and IR remote control signals, but they do not perform video signal processing. Another embodiment is a fiber optic cable with an electrical signal connector module that integrates a video signal processing chip.

A signal is transmitted to an external device through a transmission channel. A data block containing capability information indicating existence/non-existence of compatibility with an extended function is received from the external device through the transmission channel. A layer field that indicates the connection layer is provided in this data block. A check is made to determine whether all the devices existing in the path are compatible with the extended function based on the value of the layer field provided in the data block, and the contents of the transmission signal are then determined.

Provided is an image sensor that is connected to a data bus to which another image sensor is connected and image data is transmitted, and a collision detection line to which the another image sensor is connected and which is pulled up to a voltage at a first level through a register. The image sensor determines, on a basis of a state of the collision detection line, whether a collision of pieces of the image data is to occur on the data bus when the image data is output, and then outputs the image data to the data bus.
