Network Handling: dynamic network selection criteria in case the user changes this preference during a download (WiFi-only vs.Pause/Resume Downloads: provide a way for users to temporarily halt downloading.Download Notifications: display download progress in a notification as an aggregate of all the files related to one ‘downloadable video’.We created the Netflix DownloadManager for the following reasons: However, it didn’t ultimately allow us to create the UX we needed. This component was easy-to-use and handled some of the functionality we wanted. We initially looked at Android’s DownloadManager as the mechanism to actually transfer files and data to the client. Title-level metadata and artwork (cached to disk).Media files: Primary video track 2 audio tracks (one primary language plus an alternate based on user language preferences) 2 subtitle tracks (based on user language preferences) Trick play data (images while scrubbing).Content manifest (URLs for audio and video files).
For Android, we used the technical spec to define which pieces of data we’d need to transfer to the client in order to provide a single ‘downloaded video’: A technical spec was created that represented a balancing act of meeting license requirements, member desires, and security requirements (protecting from fraud). How Do Downloads Work?įrom an organizational perspective, the downloads feature was a test of coordination between a wide variety of teams. Fortunately, our Consumer Insights team also had enough time to qualify our initial user-experience ideas with members and non-members before they were built. We aimed to create a great experience with just the right amount of scope, and we could iterate and run A/B tests to improve the feature later on. We chose an aggressive timeline for the feature since we wanted to deliver the experience to our members as soon as possible.
We adopted some guiding principles based on general Netflix philosophies about what kind of products we want to create: the Downloads interface should not be so prominent that it’s distracting, and the UX should be as simple as possible.
on a train or plane)įrom a product perspective, we had many initial questions about how the feature should behave: What bitrate & resolution should we download content at? How much configuration should we offer to users? How will video bookmarks work when offline? How do we handle profiles?
