Comcast is one of the largest media companies in the world. Their Xfinity brand focuses on providing television, high-speed internet, and telephone services, as well as security and automation for residential and business customers.

With the launch of the iPad in 2010, Comcast Interactive Media, the group responsible for developing and overseeing digital media initiatives, immediately recognized the device—and its smaller phone counterparts—as both a supplement to and a potential future replacement for the traditional set-top box. Their CEO even filmed a promotional video illustrating how an iPad could be used to change the channel on a set-top box. They initially hired us to help assess the feasibility of making their channel-changing demo a reality.

What began as a two-week consulting agreement has evolved into a relationship lasting over fifteen years. Comcast typically reserves Mercurians for six to twelve-month increments to work alongside their internal development team.

Key Considerations

Channel Success

One of the first challenges Mercury faced was how to effectively display a channel guide featuring hundreds of channels, all containing two weeks’ worth of programming information, without sacrificing scrolling performance. The team developed a proprietary content delivery mechanism that condensed a massive amount of text into a compact, easy-to-consume binary string that was then unpacked on the client side, enabling easy caching and offering features such as filtering and search.

Creative Downloading

In the initial version of the TV Go app, offline downloading posed a challenge because the video needed to stay both DRM protected and compatible with other features like parental controls. Due to their extensive video library, Comcast was hesitant to create yet another encode to support this feature in the application. Therefore, Mercury developed a method to capture the HLS stream, download its segments, and stitch them back together on the mobile device once completed.

Results

Our first Xfinity TV mobile engagement introduced a product that allowed users to browse a TV guide, change channels on their set-top box, and initiate recordings from their iPad and iPhone. An Android app soon followed, again pairing Mercury and Comcast team members.

Key achievements and developments include:

  • Recognition with an Emmy Engineering Certificate in 2011 for the innovative Xfinity TV app

  • Development of the Xfinity TV Sports Remote application

  • Creation of pioneering functionality allowing customers to browse DVR recordings and download content for offline viewing

  • Integration of all features into the current Xfinity Stream app, which continues to lead the offerings from television providers
