How Hulu Scaled Its Multi‑Device Video Platform with MPEG‑DASH

Overview

This article is the transcript of a 2015 presentation by Hulu senior software development manager Li Bin at the TOP100 Global Software Case Study Summit, titled “Evolution of Hulu’s Full‑Platform Video System.” Hulu was founded in 2006 as a joint venture of Fox Broadcasting Company, Disney‑ABC Television Group, and NBCUniversal Television Group. The service launched in March 2008 as a web‑only platform offering free access to the previous day’s TV programs in exchange for a short advertisement. In November 2010 Hulu introduced a subscription tier ($7.99 per month) that allowed viewing on PCs, iPhone, iPad, Samsung Blu‑ray players, PlayStation 3, and later many other devices. Today Hulu delivers content to hundreds of devices across three categories: desktop, mobile, and living‑room devices.

From the beginning, Hulu’s technology team built the entire service in‑house rather than outsourcing. The team created everything from the front‑end player to the back‑end video‑processing pipeline, client applications for various devices, support services, recommendation algorithms, and a big‑data analytics platform. Hulu’s Beijing R&D center, the only site outside the United States, has played a pivotal role in developing the front‑end players, back‑end processing pipelines, video support services, and quality‑monitoring tools.

Hulu’s full‑platform video system is based on MPEG‑DASH and was designed to support a wide range of devices and environments through continuous evolution and innovation.

Video System Requirements and Challenges

The core requirement of Hulu’s video system is to enable every user, on any device, to watch any Hulu video—including the latest TV episodes and classic movies—in the shortest possible time. This requirement creates several challenges:

Rapidly growing user base : By 2015 Hulu had over 9 million registered users, with traffic spikes that often double the normal load, demanding high scalability.

Expanding content library : Partnerships with hundreds of content providers result in a massive and continuously growing video catalog, requiring scalable storage and delivery.

Broad device support : Hulu must serve web browsers, iOS, Android, and many US market devices such as Roku, Xbox One, PlayStation 4, Windows 10, etc., each with different playback capabilities, DRM schemes, and streaming stacks.

Unique business model : Hulu needs to deliver both DRM‑protected content videos and high‑quality ad videos. This requires supporting multiple DRM systems (Microsoft PlayReady, Google Widevine, Apple FairPlay, Adobe Access) and handling diverse ad formats from various sources.

These challenges are compounded by the need to provide a seamless “no‑break” experience across devices, especially living‑room hardware that mimics traditional TV viewing.

Through long‑term evolution, Hulu’s video system has matured into a stable, high‑performance platform built on MPEG‑DASH, capable of handling the diverse playback requirements, DRM protections, and advertising needs across all supported devices.
