摘要： An AVR device in accordance with one or more embodiments connects audio and video source devices to audio and video rendering devices. A front panel user interface including a display is integrated in the housing of the AVR device. Input-output (IO) modules are coupled to a backplane board in the housing to be connected to the source devices and the rendering devices. The IO modules include at least one network interface. System-on-Modules (SoMs) are mounted on the backplane board. The SoMs are configured to decode and process audio and video data received from the audio and video source devices for rendering by the audio and video rendering devices and execute an operating system generating a GUI displayed on the display of the front panel user interface. A video subsystem module on the backplane board is configured to route the audio and video data between the plurality of SoMs and the IO modules.

摘要： A networked speaker device includes a sealed housing and an Ethernet port in the housing for receiving power and audio data from a network router via an Ethernet cable. A power supply subsystem in the housing manages the power received at the Ethernet port. A microprocessor subsystem, powered by the power supply subsystem, receives and processes the audio data to generate output audio signals. A digital audio amplifier, powered by the power supply subsystem, amplifies the output audio signals to drive a speaker driver to render an audio output. The device also includes at least one heater resistor in the housing powered by the power supply subsystem. The at least one heater resistor is controlled by the microprocessor subsystem to automatically heat the interior of the housing when temperature inside the housing falls below a given temperature.
