    摘要: In an embodiment, a content array represents media content available from a media server. The content array, sent by a media server in response to a request, lists content program objects that represent media content to be available from the media server. The media server receives a message for altering a transcoding priority of the selected content program object that represents media content not previously transcoded by the media server, and sends a return code for indicating whether the transcoding priority was successfully altered in response to the message. In a further embodiment, a media server system includes a transcoding queue with references to a plurality of content program objects that include an object method for altering a transcoding priority, and includes a transcoder configured to transcode media content associated with the content program objects according to the transcoding priority of each content program object of the transcoding queue.

    摘要: A client device implements a media player and a proxy application. The media player controls playback of media content on the client device. The proxy application is implemented to request a playlist from a media server, where the playlist corresponds to the media content. The proxy application receives the playlist from the media server, and the playlist includes encryption key reference parameters to obtain an encryption key. The proxy application modifies the playlist to include local encryption key access parameters for the media player, and the modified playlist is communicated to the media player. The proxy application can then receive a request for the encryption key from the media player that utilizes the local encryption key access parameters included in the modified playlist, and the proxy application securely communicates the encryption key to the media player.

    摘要: In embodiments of an object model for domain-based content mobility, a client object model architecture (146) is configured for scalable and adaptive implementation to interface a mobile client device (128) with a media server (126) for wireless, secure download of media content (136) to the mobile client device. The client object model architecture can be implemented for domain-based control of a software application that invokes a media player (142) on the mobile client device, and interfaces with the media server that communicates the media content to the mobile client device. The client object model architecture also controls domain discovery of the media server, domain-based registration of the mobile client device with the media server, channel change requests, and solicited and unsolicited channel changes.

    摘要: A method is provided for viewing a bookmarked video clip. The method includes establishing communication over a broadband network with a first network element on which at least one bookmark resides. The bookmark includes metadata identifying a bookmarked video clip of a video program and specifies a network address at which the bookmarked video clip is located. Upon user request, metadata associated with a specified bookmark is received. Communication is established with a second network element on which the specified bookmarked video clip is located using the network address of the specified bookmarked video clip provided in the metadata. The bookmarked video clip is received from the second network element. The bookmarked video clip is encrypted in accordance with a digital rights management scheme. The bookmarked video clip is decrypted and rendered.

    摘要: Method and apparatus for distribution and synchronization of cryptographic context information is described. An aspect of the invention relates to synchronizing an encryptor and key management logic in a video distribution system. A request message is received from the encryptor. The request message includes authentication data and stream-dependent parameters associated with an internet protocol (IP) packet stream to be encrypted. Authenticity of the encryptor is verified using the authentication data. A cryptographic context for the IP packet stream is generated having the stream-dependent parameters and at least one encryption key. A reply message is sent to the encryptor having the at least one encryption key. Key stream messages having the cryptographic context are distributed towards user devices. The user devices are receiving an encrypted version of the IP packet stream generated by the encryptor.

    摘要: In embodiments of secure progressive download for media content playback, a client device (128) implements a media player (142) and a proxy application (144). The proxy application is implemented to receive media content (136) from a media server (126), and the media player controls playback of media content (148) on the client device. The proxy application receives the media content (136) encrypted and formatted by the media server for playback by the media player, and the proxy application initiates storing segments of the media content (148) as encrypted media content on the client device. The proxy application also requests an encryption key (124) to decrypt the encrypted media content for playback by the media player. The proxy application receives the encryption key from a key server (122) and stores the encryption key on the client device to decrypt the encrypted media content when requested by the media player.
