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.

An apparatus comprises at least one processing device, the at least one processing device being configured to receive an encapsulation of two or more types of content associated with a camera system, the two or more types of content comprising one or more video signals and one or more data signals. The at least one processing device is also configured to separate the encapsulation into the two or more types of content to obtain the one or more video signals and the one or more data signals, to output at least a given one of the one or more video signals to a first display unit, and to provide at least a given one of the one or more data signals to at least one of (i) a controller associated with the first display unit and (ii) a second display unit.

Display with an appropriate luminance dynamic range is realizable on a receiving side. A gamma curve is applied to input video data having a level range from 0% to 100%*N (N: a number larger than 1) to obtain transmission video data. This transmission video data is transmitted together with auxiliary information used for converting a high-luminance level on the receiving side. A high-level side level range of the transmission video data is converted on the receiving side such that a maximum level becomes a predetermined level based on the auxiliary information received together with the transmission video data.

A multi-channel image receiving method includes receiving, from a network camera supporting a plurality of channels, access information for registering a first channel among the plurality of channels and profile information on a second channel other than the first channel, registering the first channel as a regular channel by using the access information, registering the second channel as a virtual channel by using the profile information, requesting the network camera to transmit an image through the second channel by using the profile information, and receiving and storing the image transmitted from the network camera through the second channel.

The present invention proposes a signalling method which can support effectively next-generation broadcast service in an environment which supports next-generation hybrid broadcast using terrestrial broadcast networks and the Internet. The signalling method comprises a broadcast reception method which can use a mobile reception device or can be used even in an indoor environment. The broadcast reception method may comprise the steps of: receiving a broadcast signal including service; establishing a web socket connection from an application of a companion screen device; generating a notification message for the service; and transferring the notification message to the companion screen device through the web socket connection.

Systems and methods are disclosed for operating a surveillance system and managing beacon-augmented surveillance data. A surveillance system may include a camera, a controller, and a transceiver. The camera may be configured to generate image data. The controller may be configured to generate image metadata that indicates a surveillance system identifier, upload the image data and the image metadata to a server, and generate a beacon that indicates the surveillance system identifier. The transceiver may be configured to transmit the beacon.

A system for transmission of imaging metadata comprises a sensor configured to capture audiovisual data and a data transmission device. The data transmission device receives captured audiovisual data from the first sensor and receives metadata, wherein the metadata is metadata of a first type. The data transmission device generates a data structure corresponding to a first frame of a video feed, wherein the data structure is generated in accordance with a predefined data specification, wherein generating the data structure comprises setting an indicator in the data structure to indicate that a second type of metadata should not be read from a first field in the data structure and writing the first metadata to the first field in the data structure. The data transmission device transmits the data structure along with the captured audiovisual data.
