Audio video receiver (AVR) architecture
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.
