Embodiment Construction

[0033] Systems and methods are described for an integrated cinema amplifier and renderer system having a power supply stage that distributes power over multiple channels for rendering immersive audio content in a surround sound listening environment. The amplifier dynamically detects maximum and net power availability and needs based on audio content by decoding audio metadata, and dynamically adjusts gain to each channel or set of channels based on content and operating / environmental conditions. The transport format transports lighting data along the same bus as power and audio content to synchronize lighting control with audio content. The multi-channel amplifier includes power stages that power the cinema lights and integrated speaker lights to provide lighting power and control signals via the same power subsystems and connectors as the power and audio lines. The amplifier may include redundant power supplies or a multi-phase power subsystem and a monitor that monitors the...

Abstract

Embodiments include a power source that outputs power to drive speakers and lights in a venue; a control unit that is coupled to the power source and outputs multi-channel digital audio data to the speakers and light control data to the lights; Outputs are coupled to speakers and lights and transmit power, digital audio data, and light control data to a unified transmission bus for the speakers and lights. Lighting control data includes metadata superimposed on digital audio data and power. Other actuators than lights may also be used, such as, for example, steam / water generators, scent / aroma generators, support movement, LCD displays, hologram generators, etc.

Description

technical field [0001] One or more implementations relate generally to distributed amplification control and signal / power transmission systems for audio power amplifiers used in movie theaters and other applications. Background technique [0002] With digital audio, digital cinema and new immersive audio formats such as Dolby ), cinema sound has undergone significant changes. In many large cinema environments, many channels of audio are now available for playback through large speaker arrays. The Dolby Atmos format includes audio objects and beds (channel-based audio), where an audio object can be thought of as a grouping of sound elements that can be perceived as emanating from one or more specific physical locations in the listening environment. Such objects can be static (stationary) or dynamic (moving). Audio objects are controlled by metadata that define the position of a sound at a given point in time, among other functions. When objects are played back, they are ...
