This document covers the basics of the bigscreen-player high level architecture. It describes an overview of the internal workings that is useful to understand in order to carry out development and possibly contribute to the code base.

Further setup code and specific examples can be found in the repo itself. A good place to start is the README.

Dependencies

As it stands, the player relies on two dependencies:

Dash.js

Our custom fork of the reference implementation of the dynamic adaptive streaming over http protocol. Used for MSE (Media Source Extension) capable devices. This is required in specifically by bigscreen-player, when the mse-strategy is used.

imscJS

Our custom fork for rendering subtitles.

Architecture

Player Component

This stage provides a wrapper for the interaction with all of the individual strategies and is what bigscreen-player uses to interact with the video element, at its core.
