    摘要： There is disclosed a video player comprising a Widevine decoder, further comprising: a receiver for receiving an asset and an associated manifest file; a search engine for searching the manifest file to identify a KeyID field; a Widevine header creation module for creating a Widevine header including: a KeyID field corresponding to the identified KeyID field of the asset manifest file; and a ContentID field based on the identified KeyID field of the asset manifest file, wherein the format of the KeyID field and the created ContentID field of the created Widevine header are different; an interface for transmitting a request for a license to a Widevine license server, the request including the created Widevine header, and for receiving a Widevine license from the Widevine license server responsive to the request; and a controller for accessing video content associated with the asset using the Widevine license. There is disclosed a Widevine license server configured to: receive a license request including a Widevine header from a video player; transmit the Widevine header to a Widevine processing function; receive the ContentID field of the Widevine header from the Widevine processing function; parse the ContentID field, and in dependence on identification of the syntax of said field, using the KeyID field to obtain a Widevine license; and transmit the accessed Widevine license to the video player.

    摘要： Techniques and mechanisms described herein facilitate the management of digital rights for media content item presentation. According to various embodiments, a request for a content decryption key may be received at a media application implemented at a computing device. The request may be transmitted by a media content player implemented at the computing device. The request may be transmitted in accordance with a designated key exchange protocol. A license for an encrypted media content item corresponding with the requested content decryption key may be identified at the media application. Based on information included in the license, encrypted key material may be decrypted to create the requested content decryption key via a processor at the computing device. The requested content decryption key may be provided to the media content player.
