A device, system, and method synthesizes personalized linear television experiences from on-demand assets, live event video, streaming graphics, and dynamic ad insertion, where portions of the broadcast day are scheduled for globally shared viewing events, where other portions are scheduled for distinct programming for various audience segments. Vector graphics are streamed independently of the video and rasterized locally to improve quality and contextualization of the graphics layer while gaining the efficiency of leveraging the same cached video assets for linear and on-demand applications. The system includes origination services transforming and publishing linear television schedules, video, and graphics to a distribution cache, a live event server streaming live performances, an advertising server providing targeted advertising, a personalization server, and assembly services stitching the elements to create a continuous experience of video and graphics for a media player to receive and render for each channel selected by the viewer.

The present invention is a method and apparatus for watermarking text or vector graphics documents. It is based on character-wise or vector graphics element-wise grayscale or color modulation. At high resolution, halftone or dither modulation can also be used in addition or in place of grayscale / color modulation, for printed representation of electronic document. For the detection, the document is acquired through an acquisition device, document segmentation is performed, characters / elements are segmented, the watermark signal is estimated and the information is decoded. Although the proposed scheme mostly addresses the watermarking of hard-copy documents, it can easily be integrated into electronic document editing and acquisition tools, and the watermark is attached to the document electronic version. The invention is applicable either using expensive high- resolution printing and acquisition devices, either using common cheap low-resolution devices, depending on the application needs. The proposed scheme is suitable for example to the protection of security documents, contracts, technical and commercial documentation; it can use any physical support like paper, cellulose, or plastic; it can be used for copy protection, authentication, or tamper proofing; finally it can also be applied to other non security-related applications, such as document tracking, as well as document embedded annotation and watermarked-assisted automatic processing.

A map server generates vector descriptors and corresponding style identifiers for rendering a map image. Each vector descriptor indicates a geometry of a respective map element in accordance with a vector graphics format, and each style identifier identifies a style according to which the corresponding map element is rendered. The map server then causes map data including the vector descriptors and the style identifiers to be transmitted to the client device via a communication network. When the map server receives a request for style data for modifying a map image at the client device, the map server generates a description of visual characteristics for one or more styles identified by the style identifiers included in the map data previously provided to the client device and causes the description of visual characteristics to be transmitted to the client device for applying to the vector descriptors at the client device.

A “Vector Graphics Encoder” encodes vector graphics in a randomly accessible format. This encoding format enables particular portions of encoded images to be directly accessed, at any desired level of zoom, without processing or otherwise decoding the entire image. This random-access format is based on a coarse image grid of partially overlapping cells wherein each cell is defined by a “texel program.” Unlike fixed-complexity cells used by conventional vector images, each cell defined by a texel program is locally specialized without requiring global constraints on the complexity of each cell. The texel program for each cell is provided as a variable-length string of tokens representing a locally specialized description of one or more of layers of graphics primitives overlapping the cell. Images are then rendered by interpreting the texel programs defining one or more cells.
