This document outlines a project called MediaCast that aims to create a cheaper alternative to Apple TV and Lightning Digital AV Adapter. The solution is a $35 Chromecast that allows users to share and stream photos and videos via a mobile app. The app will allow annotation and slideshow features. The MVP will focus on annotating photos, casting photos and videos to the Chromecast, and creating slideshows. The project is split into milestones over 10 weeks with tasks assigned to three team members to implement features on iOS, Android, and Chromecast. The goal is to create a simple and interactive photo streaming app with annotation capabilities that has little competition in the market.
