OpenTV ION building blocks

Here is is a detailed view of the OpenTV ION building blocks.

GUI

In the diagram above, the compound user interface elements are often referred to as screens or views. There are a number of UI elements within each screen. These are identified and further broken down into different smaller components. There are common elements used across the screens. In the OpenTV ION source code, you get more detail on the whereabouts of these logical structures.

Accessibility

GUI elements are enabled for accessibility wherever it is deemed necessary and beneficial to the end users.

Configuration

App UI Skin (colors, fonts) can be customized as per operator needs. Also OPF platform end point URL can be specified in the configuration and can be bundled along with source code during app binary generation. More details can be found here.

Language bundle

All strings are localized and can be modified for supported languages - English, Arabic and French. More details can be found here.

JS to native bridge

An interface to link JS source code with native code to achieve certain functionalities within the app to meet business needs.

App state management

Each view is backed by one or more redux store (cached) metadata elements which are fetched asynchronously from relevant sources (micro services or OS internal interfaces).

Utilities 

Utilities are logical groups of functionality used by the UI elements. 

Utility name

Description

OVP  

A group of logic that helps to interact with micro services of OpenTV Video Platform (MDS, IAS, RMG etc):

  • Account - IAS, RMG to manage the sign-in accounts and handle rights management for the content

  • ADM - to manage account PIN and limit the number of devices to watch per account

  • Personalization 

    • CDS and CDG - mainly to aggregate content from different sources and provide metadata to clients in a consistent manner

    • UAV - to manage favorite content and channels, bookmarks of partially watched non-live content and related video metrics reporting

  • Messaging - mainly to push messages to client devices

  • Content Storage - CDVR mainly to store and manage schedule recordings as well as recorded content for client devices

OS

A group of logic that helps to interact with the underlying OS and its features to be used in the GUI as needed:

  • Player components 

  • Orientation 

  • Date picker in EPG 

  • Loading of assets 

  • Local storage

  • Search (for Google Assist only for Android TV)

  • Apps & Games (only for Android TV)

  • Keyboard (only for Android TV)

Implementation is specific to each device platform - Android and iOS 

Thirdparty

A group of logic that helps to interact with native OS or third party servers (non-NAGRA):

  • Firebase - mainly to collect a broad set of analytics based on user interactions within the app. This will get collated and can be viewed in Firebase dashboard.

  • GDPR - OpenTV ION app is compliant with GDPR regulations as it doesn't store user information within the app, and only non-personalised usage patterns are aggregated via Analytics

  • Cast SDK - to show Cast option while watching content on mobile/tablet

  • SmartBeam - specific to an operator who deployed OpenTV ION in their region

Business logic

There are specific filters applied to backend APIs based on user settings and operator deployment needs so that appropriate content is shown in GUI.

  • Capabilities - Catch-up content

  • Filters - e.g. number of days live metadata to show in EPG 

  • Identify CU - logic to identify if catch-up is available in metadata

  • Content Validity - logic to filter valid content before presenting it to the user in GUI

  • Search - logic to filter content based on a set of rules (e.g. actor, genre, type of content - catch-up, live, etc.)

  • Entitlements - logic to show the content rights available associated with account before playback

  • Browse - logic to show a list of catch-up and on-demand content based on operator 

OTV Player

A NAGRA-owned player product that has an SDK for different platforms is integrated (per platform) into the application.
