Abstract: A Trustonic DRM Plug-in is provided that can be downloaded and operate in conjunction with an Android framework. The solution also includes a PVP with the downloadable DRM. The system includes components that can be added by Trustonic based on the Android 4.3 Framework in addition to current t-base 300 that can be used by any DRM vendor. The system enables the DRM to be downloaded in the field since all DRMs could use the standard API services of the Android 4.3 OS. With a codec component employed like H.264 or HEVC that can use the PVP with the downloaded DRM component, the Android video player can use the component to satisfy HD content security requirements.

Abstract: A method and system provide the ability to process video content on a headend. A video processing server authenticates with a key server and public keys are exchanged. The key server generates and places a content key into a document that is signed with the public key. A client on the video processing server receives the document, extracts the content key, and saves the content key to a database. The video content is encrypted using the content key and DRM signaling elements are added to a manifest. The encrypted video content and manifest are received in the head end, a key ID is extracted from the manifest and provided to the CPIX client to retrieve the content key from the CPIX document. The encrypted video content is decrypted using the content key resulting in clear content that is provided to a downstream packager that encrypts and repackages the content for transmission to recipients.

Abstract: A method and system is provided for efficient interruptible transfer of protected media assets. The method of asset transfer uses a segmented asset transfer paradigm which makes possible the implementation of such features as watch as you transfer and offsetted resumption of interrupted transfers. Implementation strategies of these features with support for segmented and contiguous media assets are also disclosed.
