Further, the controller is configured to display, on the display, a plurality of icons including a first icon and a second icon. In addition, the first icon includes a first default image identifying the first input and the second icon includes a second default image identifying the second input, change the first default image to a first video image currently being played on the first external device and corresponding to the first image signal received from the first external device in response to the first icon being selected if the first external device is connected to the image display device, and change the first video image back to the first default image in response to the second icon being selected.

Provided is a data stream allocation system capable of suppressing inequality in processing loads on a plurality of servers and delays in analysis processing at the servers when the servers analyze the objects of analysis using data streams obtained from a plurality of camera systems. The allocation determination unit 4 allocates data streams obtained from a plurality of camera systems to a plurality of servers according to the unevenness in the number of objects in the surveillance region. Then, the distribution unit 5, in accordance with the results of the allocation of the data streams to the plurality of servers, distributes each of the data streams obtained from the camera systems to the server to which the data stream has been allocated.

Aspects of the disclosure provide for a method. In some examples, the method includes receiving a video stream comprising multiple frames, analyzing the video stream to compare data values representing an image pixel at a specified location in a first of the frames to programmed data values for the image pixel at the specified location in the first of the frames, determining that the video stream includes incorrect data responsive to the data values representing the image pixel at the specified location in the first of the frames being different from the programmed data values for the image pixel at the specified location in the first of the frames; and taking action responsive to determining that the video stream includes incorrect data.

The present disclosure relates to systems and methods for transmitting a plurality of channels of primary analog signals to at least one terminal device. The method may include combining, by a signal combining device, the plurality of channels of primary analog signals into a combined analog signal. The method may also include transmitting, by the signal combining device, the combined analog signal to a signal dividing device via a cable. The method may further include dividing, by the signal dividing device, the combined analog signal into a plurality of channels of divided analog signals, each of the plurality of channels of divided analog signals corresponding to one of the plurality of channels of primary analog signals. The method may still further include transmitting, by the signal dividing device, the plurality of channels of divided analog signals to the at least one terminal device.

In described examples, a receiver includes a receiver input adapted to receive input data. A selector is coupled to an output of the receiver and is configured to generate a destination indication at an output of the selector. A switch is coupled to the receiver input. The switch is adapted to generate a first transmission at a switch local output in response to an indication of the selector output and the input data. The switch is further adapted to generate a second transmission at a switch system output in response to the input data. The switch local output is adapted to be coupled to a first destination node, and the switch system output is adapted to be coupled to a second destination node.

This invention provides a system and method for utilizing a wireless, handheld communication device to image a scene in multiple directions, so as to include multiple parties in addition to the user, and also, optionally, to project images on a plurality of display screens—for example a user-facing screen on the front face of the phone and an opposing screen on the rear/back face of the phone that faces (e.g.) a chat participant other than the user (an audience). The housing of the smartphone is adapted to provide a multi-camera and multi-screen arrangement. More particularly, the housing of the smartphone is adapted to include (at least) a front-directed camera and a rear-directed camera on respective front and rear faces, and openings along the left and right side edges for small-scale cameras and associated protective windows that are directed to image the left and right areas adjacent to the phone.

A submersible inspection drone used for inspection of liquid cooled electrical transformers can include a number of separate cameras for imaging the internal structure of the transformer. The submersible can be configured to communicate to a base station using a wireless transmitter and receiver. The cameras on the submersible can be fixed in place and can be either static or motion picture cameras. The submersible can include an input/output selector capable of switching between the camera images, either through commanded action of a user or through computer based switching. In one form the input/output selector is a multiplexer. The base station can be configured to display images from the cameras one at a time, or can include a number of separate viewing portals in which real time images are displayed. The base station can include a demultiplexer synchronized to the multiplexer of the submersible.

In various embodiments, a method for processing video streams is described. A plurality of video streams for transmission to a display device are received. The plurality of video streams have respective initial image quality levels. An estimated gaze location of a user of the display device is estimated. At least one video stream of the plurality of video streams is processed to have a modified image quality level based on the estimated gaze location. The modified image quality level is less than a corresponding initial image quality level. The plurality of video streams are transmitted to the display device.
