Abstract: A platform-in-platform (PIP) system allows for the access of multimedia content from different platforms on a single platform. The PIP system includes a first content platform configured to operate a PIP front-end module; a PIP back-end module configured to authenticate a user according to a user credential and to generate a session token in response to authenticating the user; and a content delivery back-end module configured to store multimedia content not available via the first content platform. The PIP front-end module is configured to provide a user credential to the PIP back-end module, to receive the session token, and to provide the session token to the content delivery back-end module. The content delivery back-end module is configured to verify the session token and to provide access to the multimedia content to the PIP front-end module.
