## Overview

This repository is a set of Roku SceneGraph channel samples, with DeepLinking showing the broadest feature set and sibling directories presenting narrower or incremental examples. The likely user journey is browsing a content grid, opening details or episodes, and playing a selected video; the tree also identifies deep linking, bookmarks, subscriptions, and video ads as distinct capabilities. No source excerpts were provided, so runtime relationships below are tentative and marked dashed without evidence paths; the README describes the sample’s purpose but not its internal call flow.

Main entry points: [`DeepLinking/components/MainScene.brs`](https://github.com/rokudev/scenegraph-master-sample/blob/master/DeepLinking/components/MainScene.brs) (Main scene), [`DeepLinking/components/UILogic/VideoPlayerLogic.brs`](https://github.com/rokudev/scenegraph-master-sample/blob/master/DeepLinking/components/UILogic/VideoPlayerLogic.brs) (Player logic), [`DeepLinking/components/UILogic/GridScreenLogic.brs`](https://github.com/rokudev/scenegraph-master-sample/blob/master/DeepLinking/components/UILogic/GridScreenLogic.brs) (Content grid), [`DeepLinking/components/UILogic/DetailsScreenLogic.brs`](https://github.com/rokudev/scenegraph-master-sample/blob/master/DeepLinking/components/UILogic/DetailsScreenLogic.brs) (Details view)
