By implementing a new bitstream for a Delta-Quantization Parameter (DQP), a decoder is able to implement parallel decoding of multiple coding units within a largest coding unit. In some embodiments, the DQP is placed immediately after the mode information of the first coding unit. In some embodiments, the DQP is placed after the mode information of the first non-skipped coding unit. In some embodiments, the DQP is placed after the first non-zero coded block flag.

An imaging system for a portable electronic device includes a variable aperture between a lens group and an image sensor. The variable aperture is defined by an electrochromic stack that defines a switching region and a central non-switching region. The non-switching region can be etched through the same material or set of materials defining the switching region and is backfilled with a dielectric transparent material having an index of refraction substantially equal to an average index of refraction of the layer(s) of the switching region of the electrochromic stack. This construction substantially reduces visible light absorption of the variable aperture.

Methods are described for the commissioning of optically switchable window networks. During commissioning, network addresses are paired with the locations of installed devices for components on a window network. Commissioning may also involve steps of testing and validating the network devices. By correctly pairing the location of a device with its network address, a window network is configured to function such that controls sent over the network reach their targeted device(s) which in turn respond accordingly. The methods described herein may reduce frustrations that result from mispairing and installation issues that are common to conventional commissioning practices. Commissioning may involve recording a response to a manually or automatically initiated trigger. Commissioning methods described herein may rely on user input, or be automatic, not requiring user input.

In an example method, for a plurality of octants, residual information is obtained for one or more vertices of the respective octant, where the vertices correspond to respective points in a three-dimensional lookup table. The lookup table is decoded recursively as follows: at least a first one of the plurality of octants is decoded by reconstructing at least a first color sample value from the residual information for at least a first vertex of the first octant; and a plurality of second octants in the plurality of octants are decoded, where the second octants are obtained by splitting the first octant. A color transform is then applied based on the decoded lookup table.

A transcoding apparatus including a decoder and an encoder is disclosed. The decoder is configured to: receive a first bitstream output by an application; decode the first bitstream to obtain a first image and first format information of the first image; embed the first format information into the first image to obtain a second image; and send the second image to the application.

A video processing system (2) is provided with: a first input interface (21); a second input interface (22); and a CPU (231). The first input interface (21) acquires a video signal to be outputted to a display panel (10) of a display (1). The second input interface (22) acquires color temperature information indicating the color temperature of environment light emitted toward the display panel (10). The CPU (231) calculates a correction amount of the color temperature of the video signal so as to conform to the color temperature of the environment light. The CPU (231) subtracts the absolute value of the correction amount of the color temperature of the video signal so as to cancel the color temperature of the environment light when the pixel luminance of the video signal is less than a luminance threshold value. The CPU (231) outputs the video signal having the color temperature of the video signal corrected in accordance with the correction amount.

Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations. Also described are self-meshing networks for electrochromic windows.
