AVS Plugin

AVS plugin is a thunder plugin developed by metrological/amazon. it supports configurable audio sources and depends on the AVS client SDK.

• As of now it only supports general Alexa skills (without any RDK specific skill)

• Current source code is built with AVS Device SDK 1.15 & Smart Screen SDK 2.0.1

Configurations Parameters

Methods

Mute

Using this method we can mute the volume coming out of AVS SDK as well we can mute the alerts.

record

Recording voice by Alexa SDK can be toggled on/off. This overrides the hot word detection i.e. if recording is off wake-word will not work. 

Notification

dialoguestatechange This notification will come when any state change happens in the Alexa. e.g. when the AVS SDK goes from Idle -> Listening or from Listening -> Thinking -> Speaking

Plugin Build dependencies

Video catalog

With the Video Skill API, you can build skills that let customers control their entire video experience by voice.

Customers can control video devices and consume video content without invoking a specific skill. For example, the customer could do the following:

• Start video playback without specifying a provider or device
• Control a specific video device:
  • "Alexa, turn on my video device"
  • "Alexa, lower the volume on my video device"

The Video Skill API exposes below functionalities:

• Searching and playing content
• Playback controls - Pause, play, rewind, Volume Up/Down
• Turning a video device on or off
• Changing a video device's input (HDMI etc.)
• Launching an app or GUI shortcut
• Recording video content
• Channel navigation
• Video catalog ingestion

Dependency

• Alexa developer account
• AWS account (for lambda)
• OAuth 2.0
• Lambda function can be written using Node.js/Python etc.

Questions & Response

• Which of the below approach are supported for device end integration 
  
  • It should be processed by a native module (skill mapper) & then instruction sent to UI
• Any examples to simulate with a dummy operator and other auth fields to verify the video skill end-to-end? 
  • Example Link : https://github.com/amzn/sample-fire-tv-app-video-skill/tree/master/Lambda
• Are Lambda functions Alexa Hosted?
  • Lambda functions need to be hosted in users own space (it is not Alexa hosted)

• Whether it supports open wake word engines (pryon is not available to all).
  • Pryon Lite is provided on demand
• How the response from Video skill APIs should be handled?
  • The response path from Video skill API is different and will not come back to the AVS SDK. We need to implement communication mechanism similar to that of IOT endpoints.
• What are the requirement for RDK UI (any reference UI) for interacting with smart screen (interface, API etc.)
  • TBD
• What are requirement for RDK  UI to render the display card (text) in UI against each voice command
  • TBD
