摘要: A remote server generates a data stream that is broadcasted to a plurality of receivers. The broadcasted data stream includes a video track having a video data stream, a control track, and a plurality of ancillary data tracks including ancillary data. A specific template is assigned to each of the receivers. Each of the receivers renders a composite video image for display on a display device. Each of the composite video images includes the same video data stream, but each receiver uses its assigned template and selected ancillary data to render its own unique composite video image from the same video data stream.

摘要: A video generation system is configured to provide streaming video as a cloud processed service to viewers over a computing network. In response to a request from a viewer, a video source is configured to provide video and an identifier source is configured to provide an identifier for inclusion in the video. A video encoder is configured to convert the video from a first format to a second format, apply the identifier to the video, and otherwise encode the video in real-time while streaming the encoded video to the viewer. The identifier may be stored in association with the account information of the viewer and used for identifying the viewer a source of an unauthorized video copy.

摘要: Media content is delivered to a variety of mobile devices in a protected manner based on client-server architecture with a symmetric (private-key) encryption scheme. A media preparation server (MPS) encrypts media content and publishes and stores it on a content delivery server (CDS), such as a server in a content distribution network (CDN). Client devices can freely obtain the media content from the CDS and can also freely distribute the media content further. They cannot, however, play the content without first obtaining a decryption key and license. Access to decryption keys is via a centralized rights manager, providing a desired level of DRM control.

摘要: Some embodiments are directed to a method and to a device allowing an access control system to be applied to the protection of streamed video. The inventive system and associated method allow an existing access control system of Marlin type to be used innovatively based on the execution of two successive operation phases allowing DRM rights to be acquired followed by the delivery of content and the decryption thereof.

摘要: A unified system of programming communication. The system encompasses the prior art (television, radio, broadcast hardcopy, computer communications, etc.) and new user specific mass media. Within the unified system, parallel processing computer systems, each having an input (e.g., 77) controlling a plurality of computers (e.g., 205), generate and output user information at receiver stations. Under broadcast control, local computers (73, 205), combine user information selectively into prior art communications to exhibit personalized mass media programming at video monitors (202), speakers (263), printers (221), etc. At intermediate transmission stations (e.g., cable television stations), signals in network broadcasts and from local inputs (74, 77, 97, 98) cause control processors (71) and computers (73) to selectively automate connection and operation of receivers (53), recorder/players (76), computers (73), generators (82), strippers (81), etc. At receiver stations, signals in received transmissions and from local inputs (225, 218, 22) cause control processors (200) and computers (205) to automate connection and operation of converters (201), tuners (215), decryptors (224), recorder/players (217), computers (205), furnaces (206), etc. Processors (71, 200) meter and monitor availability and usage of programming.

摘要: A distributed database management system provides a central database resident on a server that contains database objects. Objects, e.g., program guide data, to be replicated are gathered together into distribution packages called “slices,” that are transmitted to client devices. A slice is a subset of the central database which is relevant to clients within a specific domain, such as a geographic region, or under the footprint of a satellite transmitter. The viewer selects television programs and Web content from displayed sections of the program guide data which are recorded to a storage device. The program guide data are used to determine when to start and end recordings. Client devices periodically connect to the server using a phone line and upload information of interest which is combined with information uploaded from other client devices for statistical, operational, or viewing models.
摘要翻译: 分布式数据库管理系统提供驻留在包含数据库对象的服务器上的中央数据库。 要复制的对象,例如节目指南数据被聚集在一起,被分发到被称为“切片”的分发包中,被传送到客户端设备。 切片是中央数据库的子集,其与特定域内的客户端(例如地理区域)或卫星发射机的占用面积相关。 观众从记录在存储装置中的节目指南数据的显示部分选择电视节目和网页内容。 程序指南数据用于确定何时开始和结束记录。 客户端设备使用电话线定期连接到服务器,并将感兴趣的信息与从其他客户端设备上传的用于统计,操作或查看模型的信息相结合。
