Cross Platform Extras HTML API

Cross-Platform Extras for HTML (CPE-HTML) defines an API between studios and retailers that supports portable interactivie experiences. CPE-HTML uses the following model:

CPE Model

A content provider (studio) need only implement a package once to run across mulitple retailers. Similarly, a retailer need only implement a framework once to support multiple studios.

CPE-HTML is part of a family of specifications. For others, see here.

API Documentation

The CPE-HTML API defines interfaces in the following groups

  • Package Management: addresses both management of the life-cycle of the package, and access by the package to information regarding the Viewing Environment.
  • Content Access: functions to identify and/or acquire the rights and entitlements to access content as well as the ability to transfer (i.e., download) the content from its current location.
  • Account Access: provides a package the ability to establish the identity of the consumer via a sign-in process and then obtain or modify information specific to the consumer (e.g., preferences, wish lists).
  • Player Interaction: deals with the actual playback of a content file or stream. Methods are provided for obtaining a media player and then directing its operations (i.e., play, pause, trickplay, etc.).
  • Social Networking: deals with the use of social media accounts to interact with a larger community via posts, likes, and similar mechanisms.
  • Enhancements: functionality that is considered optional. The API therefore provides the package with the ability to query the framework to determine which specific capabilities are provided.
