Description PathPartner’s Wireless Display stack currently implements the Wi-Fi Alliance’s Miracast specification. The stack is being developed with the aim of being a full-fledged sink stack implementation. The Miracast sink stack allows multiple Miracast source devices (up to 8 devices) to share the screen simultaneously.

Applications PathPartner offers complete sink implementation for a wide range of applications:  Sink dongles  Wireless projectors & displays  Smart TVs & Set-top boxes  Automotive IVI platforms

Application: Application developers can use the stack API to integrate the stack into their applications or UI. The API is available as native C library or with Java-JNI bindings. Reference implementations on a platform, consists of the Core, Reference Components and test applications based on the stack API.

Core: The actual application Core. This is cross-platform component and implements all of Miracast stack and state management.

Platform Portable Components: These are platform specific components. These needs to be adapted to the platform. The interface API for the reference implementation components are clearly defined. Integrators can implement these for their platforms or license reference implementations of these components from PathPartner.
