Audio Encoding & Decoding on USP Transceivers

Introduction

The family of USP transceivers operate as both encoders and decoders. This allows them to encode and decode audio from various sources and inputs, both locally or over the network. This article covers the audio flow and capabilities of each of the USP endpoints. 

Audio Encoding Capabilities (USP-PL and PR)

The USP-PL and USP-PR have the ability to encode an audio signal from either the local HDMI input or the local analog input on the endpoint. The HDMI input audio and analog input audio can not be encoded at the same time. The active audio signal can be switched and configured through the CBOX Mentor UI. You have the options to force select an audio input or have the transceiver auto select/switch based on signal detection that works on a Last In, First Out rule.

The encoded audio signals can be sent to another USP endpoint to be decoded and to a Dante/AES67 receiver.

Audio Decoding Capabilities (USP-PL and PR)

The USP-PL and PR have the ability to decode audio from one of four ingest points and output the subscribed audio signal via the HDMI and analog audio connections. The HDMI audio output and the analog audio output can each receive a discrete audio feed. For example, the HDMI out can subscribe the a remote USP encoder's audio stream while the analog audio out is subscribed to a 3rd-party Dante audio stream.

Audio ingest points that can be decoded include:

Source 1 - local analog input

Source 2 - local HDMI input

Source 3 - 3rd-party Dante transmitter

Source 4 - another USP encoder network audio stream

Audio Encoding/Decoding on the USP-ES

The USP-ES differs slightly from the USP-PL and PR in that it does not support Dante encoding or decoding capabilities. All other capabilities remain the same.
