Hybrid media devices, which can deliver audio, video and interactive content over both broadcast and broadband, create new opportunities and challenges for broadcasters. Augmenting the broadcast experience with interactive content delivered over the Internet changes the classic one-to-many paradigm bringing it closer to a one-to-one relationship. Cross-Platform Authentication (CPA) offers an open standard for associating any media device with an online identity, which facilitates delivery of personalized services to these devices.
In April 2016, the Cross-Platform Authentication Protocol was published as an ETSI Technical Specification: ETSI TS 103 407.
The platform is a live environment based on the open source reference implementation.
