Overview

The RDK Accelerator Home UI version 3 is the latest stable version (3.9RDK_apps/6.0.0-rc4/accelerator-home-ui/settings.json#16 platformSettings version) of the RDK reference UI which provides a full featured UI with a modern minimalistic design using a dark theme.

...

• OEM logo with color accents which are customizable
• Multiple Language Support
• Casting Feature from mobile phones to premium apps such as YouTube
• Overlay Screen
• Extensive settings pages to interact with various Video, Audio, Connectivity options
• Generic UI Keymap option
• On-screen Keyboard Component for Bluetooth & Wi-Fi

Splash Screen

The app loads a new splash logo when the device boots up which remains for a few seconds and then leads to user on-boarding screens if device is booting up afresh.

Note: The Gracenote logo will be visible only on the device where required keys are provisioned.

User on-boarding

This screens shall appear only once the device is booting up.  Criteria used to detect the fresh boot is by verifying whether any previous Remote Control Unit (hereafter RCU) pairing information is available or not. If yes, device shall skip these on-boarding screens and land at the Home screen.

Same features and functionalities are exposed under Settings menu as well for the user to interact later.

Remote Pairing

UI initiates Bluetooth scan for HID profile to connect and pair with at this point with a configured time-out. How to put the RCU in Bluetooth pairing mode is dependent on the RCU design which is not within UI scope.

Bluetooth Pairing is done through RCU on UI

Navigator UI will prefer to use Remote Control plugin on supported platforms to pair with RCU instead of classic Bluetooth plugin. Only one plugin shall be used to onboard the RCU - if preferred Remote Control plugin is available it will not fall back to use Bluetooth plugin to scan and pair with RCU.

RCU Pairing using RemoteControl plugin

Note: this Note: this feature of automatic RCU pairing requires RCU model support integrated with BLERCUDaemon at platform firmware build time and RemoteControl plugin enabled. If your RCU and platform does not support this feature yet, you can still pair your RCU using the Classic Bluetooth plugin based RCU pairing through the "Settings" menu detailed in later section - "Pair Remote Control".

Language Selection

The UI uses Remote Control Plugin to pair with the device if it catches any error while pairing then Bluetooth plug will be activated.

Customization (Theme and Logo)

One among the new feature in this version of UI is it allows to change the focus color, background color and logo if an operator wishes to by making necessary changes in config.js. Default config.js for reference is as below.

const themeOptions = {

      logo: 'RDKLogo.png',
      background: '0xff000000'

}

User can define an object inside theme options which need three parameters:

hex - Color accents on the UI. Default one is shade of orange.
logo - Logo at the splash and top left side on the home screen.
background - background color of the components.

User has to export a specific theme for it to apply through the UI and rebuild or re-gernerate the app bundle.

export var CONFIG = {
    theme: themeOptions['partnerOne'],
    language: localStorage.getItem('Language')!=null ? language[localStorage.getItem('Language')] : language['english']
}

  $ cd RDK_apps/accelerator-home-ui/dist/<es6>/Replace the dummy icons with original and then tar the entire contents to deploy on the offline UI location on device.

  Note: On a RDKV reference device; the lighttpd webserver is configured to load the offline UI from DOCROOT which includes the alias of the above dist file mapped for loading. Usually the dist directory contents are placed in the STB's /home/root/lxresui/

• Host the app locally to test

  It will print the local url as : http://127.0.0.1:8080 which can be loaded as url to the residentApp.sh which is responsible for offline UI url loading on STB.

...

Reference

The UI uses localstorage feature of WebkitBrowser's ResidentApp configuration for storing the user preferences. PLUGIN_RESIDENT_APP_LOCALSTORAGE and PLUGIN_RESIDENT_APP_PERSISTENTPATHPOSTFIX variables need to be configured build-time itself.

Note: the localstorage directory shall be pointed to a persistent ReadWrite section on device.

Steps to make Accelerator Home UI v3 as Device UI

Packages that are needed for Accelerator UI v3 are from meta-rdk-video layer. They will get installed into the final rootfs with necessary startup and configuration scripts if the machine configuration is enabled with below mentioned DISTRO_FEATURES.

$ DISTRO_FEATURES_append = " offline_apps build_rne "

How To...

The following section details about few debug steps to confirm some generic issues and doubts when working with an RDK-V stack and this UI.

How to confirm platform key press events are reaching UI

Platform keymap could be differing from the UI keymap which could result in unexpected behaviors or UI not responding to key press events.

In general; UI receives the key press events through webkit browser when user interacts with STB using RCU or connected keyboard.

How to check the browser is able to receive the key events and which keyCode its being received from platform:

1. Using Controller UI(a.k.a. ThunderUI); activate HtmlApp and load https://keycode.info/ as url. Controller UI is only available on a development build RDK-V image and it can be accessed from a local network connected computer where RDK-V device is connected. Note down the RDK-V deviceIP (Eg: let it be 192.168.1.30). Then from the same network connected computer; open any web-browser and type in deviceIP:9998 in the address bar.
2. Press any keys and confirm the keyCode being reported by https://keycode.info/.

How to check UI is able to receive the key events and which keyCode its being received at UI:

1. Using Controller UI(a.k.a. ThunderUI) from any local network connected computer; open ResidentApp's webinspector and go to console tab.
2. While pressing any key; corresponding keyCode will be printed at ResidentApp's webinspector console

How to debug UI not responding to key press events

1. Verify that UI is able to receive the key events
2. Verify the received key event is matching with UI specific keymap detailed at section "Key Mapping".

If the above two are not working or matching; please verify the platform integration.

If UI is not responding for the received key event and is matching with UI defined "Key Mapping"; please create a UI bug ticket or reach out to us. We'll be happy to help and resolve it for you.

Key Mapping

The version 3 UI supports a configurable keymap. Below lists the general functionality and keycode of keys. Detailed information of the default keycode mappings can found here.

...

Customization (Theme and Logo)

One among the new feature in this version of UI is it allows to change the focus color, background color and logo if an operator wishes to by making necessary changes in config.js. Default config.js for reference is as below.

const themeOptions = {
    partnerOne: {
      hex: 0xfff58233,
      logo: 'RDKLogo.png',
      background: '0xff000000'
    },
    partnerTwo: {
      hex: 0xff91c848,
      logo: 'RDKLogo.png',
      background: '0xff000000'
    },
}

User can define an object inside theme options which need three parameters:

hex - Color accents on the UI. Default one is shade of orange.
logo - Logo at the splash and top left side on the home screen.
background - background color of the components.

User has to export a specific theme for it to apply through the UI.

export var CONFIG = {
    theme: themeOptions['partnerOne'],
    language: localStorage.getItem('Language')!=null ? language[localStorage.getItem('Language')] : language['english']
}

Clone and Build Instructions

This section details about how to customize the current UI source code and develop further.

Follow the commands to run the application on you laptop.

• Firstly install Lightning CLI

• Type lng to confirm the installation. You will see the below output.

Performance Matrix

This section details the average loading time, CPU and memory utilization for this version of the UI alone. It has been measured by loading the offline version of the UI on a pre-activated webkitbrowser instance.
