In a case where a data stream is transmitted in a predetermined mode, and when a parameter that defines content of the mode is changed, the transmission device according to one aspect of the present technology switches transmission of the data stream in the mode defined by the changed parameter is started after training processing for performing data synchronization and correction of a difference between data timings of the lanes by the reception device is executed or is started without executing the training processing according to a type of a parameter to be changed. The present technology is applied to data transmission between chips.

In a method for transmitting video for a display panel between a transmitter in electronic communication with a receiver over a wireless communication channel, the method includes: receiving, by a transmitter, a frame of video data from a data source; reorganizing, by the transmitter, the frame of video data into a plurality of packets according to levels of importance of bits of the frame of video data; generating, by the transmitter, a tag for each of the packets, the tags corresponding to different relatively levels of importance of the packets; performing, by the transmitter, different protection techniques for each of the packets based on the tag corresponding to each of the packets; and transmitting, by the transmitter, the packets and the tags to the receiver for display on the display panel such that each packet is transmitted according to the different protection techniques based on their corresponding tagging.

A method of transmitting image data in a safety sensor or in a safety system is provided, in which transmission errors are recognized in that meta information is added to the image data prior to the transmission and the meta information is checked after the transmission. The image data are here transmitted by an unsafe communication link, in particular a black channel, the meta information is prepended and/or appended to the image data and/or to the partial packets, and the meta information comprises a piece of information on the structure of the image data.

An electronic device is provided. The electronic device may include a wired communication interface connected to a display device through a cable, and a controller that transmits a test signal, which includes specified data, to the display device through the wired communication interface and receives error check information regarding the test signal from the display device through the wired communication interface. The controller may sequentially change transmission characteristic values of the test signal within a specified range to transmit a plurality of test signals, and perform calibration for changing a transmission characteristic of a signal to be transmitted to the display device based on the error check information regarding the plurality of test signals.

An image capturing apparatus having a movable unit for performing image capture and a supporting unit that supports the movable unit, the movable unit including an image capturing unit that captures an object, and the supporting including a driving unit that drives so as to change the orientation of the movable unit, a position detection unit that detects the position of the movable unit, a shake detection unit that detects shake of the image capturing apparatus, a determination unit that determines a driving target position of the driving unit, based on the shake detected by the shake detection unit, and a control unit that controls the driving unit such that the position of the movable unit detected by the position detection unit converges to the driving target position determined by the determination unit.

Provided are an electronic device and an operating method thereof. The operating method of the electronic device configured to communicate with one or more source devices through a high-definition multimedia interface (HDMI) includes identifying a consumer electronics control (CEC) error corresponding to one or more source devices based on CEC communication status between the electronic device and the one or more source devices, analyzing the identified CEC error corresponding to the one or more source devices, and providing a troubleshooting information to a user of the electronic device regarding the identified CEC error corresponding to the one or more source devices.

An electronic device for processing and playing a video transmitted from an input device is provided. The electronic device includes video processors and a processor. The video processors are configured to perform processing operations based on a test video including frames received from the input device to generate a sampling video including the frames, where each of the frames include at least one pattern. The processor is configured to receive the sampling video, determine whether the sampling video is output normally or not and an output order of each of the plurality of frames on the sampling video, based on the at least one pattern, and determine whether an error occurs in at least one of the input device and the plurality of video processors, based on the output order of each of the plurality of frames and whether the sampling video is output normally or not.
