Brief Patent Description - Full Patent Description - Patent Application Claims
[0001] This is a divisional of application Ser. No. 10/893,296, filed Jul. 19, 2004, which claims priority from European Patent Application No. 03291938.3 filed Jul. 31, 2003, the disclosures of which are incorporated in their entirety. TECHNICAL FIELD [0002] The present invention relates to accessing, distributing, and presenting hypermedia documents. In particular the invention relates to a method, a hypermedia communication system, a hypermedia server, a hypermedia client, and computer software products. [0003] The invention is based on a priority application, EP 03291938.3, which is hereby incorporated by reference. BACKGROUND OF THE INVENTION [0004] Hypermedia, a term derived from hypertext, extends the notion of the hypertext link to include links among any set of multimedia objects, including sound, motion video, and virtual reality. It also connotes a higher level of user/network interactivity than the interactivity already implicit in hypertext. [0005] Hypermedia is currently realized as a set of computer-addressable files that contain pointers for linking to multimedia information, such as text, graphics, video, or audio. The use of hypertext links is known as navigating. One of the emerging important media types are temporal multimedia objects, i.e. continuous or transient media like motion pictures, audio, morphing objects etc. adding a further information dimension: time. [0006] These media types require certain computational, networking, and storage resources. MPEG (pronounced M-peg), which stands for Moving Picture Experts Group, is a family of standards used for coding audio-visual information in a digital compressed format. [0007] MPEG-4 addresses coding of digital hybrids of natural and synthetic, aural and visual (A/V) information. The objective of this hybrid coding (SNHC) is to facilitate content-based manipulation, interoperability, and wider user access in the delivery of animated mixed media. [0008] Trends in networking, in decentralization of media production and consumption, and in computer graphics point toward changes in distributing passive and interactive mixed media. Audio/video and 2D/3D synthetic graphics are merging into hybrid compositions in a variety of formats and platforms that extend the role of television and the PC. This evolution widely spans lower-bit-rate applications like video cellular telephony, and higher-bandwidth, networked, interactive, real-time media experiences like distance learning, gaming, and training. [0009] There are two multimedia object categories: the temporal transient ones with timing constraints and the atemporal ones, i.e. the persistent objects. When these objects refer each other, i.e. are in relation, they are called hypermedia objects. The relation as well as the object and their properties are denoted using a hypermedia description (language). [0010] Emerging silicon and software systems are moving toward delivery of hybrid content for real-time experiences with a high level of integration of computing resources, algorithms, and data primitives to decode, animate, render, and composite scenes. A/V objects can exist as transient or stored data in channels and media such as the Internet, ATM/BISDN communications, CD-ROM, on-line modifiable disks that page active data, archival digital libraries, and the memories of servers, decoders, PCs, graphics accelerators, and newer media processors. [0011] Various modeling schema for spatial and temporal media content are embodied in current work such as VRML 2.0 (Virtual Reality Modeling Language), Java Media 2D,/3D, and ActiveX Animation. MPEG-4 is concerned with coding of animated data, and thus with spatial-temporal relationships among A/V objects as represented in bit-streams. The requirements of MPEG-4 are so complex that bit-streams and the higher-level representations they encode are designed in isolation from the application environment. [0012] Several other cross platform video and audio standards have been established e.g. JPEG (Joint Photographic Experts Group), and a number of different MPEG standards. [0013] On the other hand MHEG (Multimedia and Hypermedia Experts Group) is a multimedia presentation standard to provide a framework for multimedia applications, to define a digital final form for presentations, which may be used for exchange of the presentations between different machines or platforms, to provide extensibility. [0014] MHEG defines the abstract syntax through which presentations can be structured. This is the definition of data structures and the fields in those data structures, through which two computers may communicate. [0015] The MHEG model is object orientated, and defines a number of classes from which object instances are created when a presentation is designed. There are several classes, and these are used to describe the way video is displayed, audio is reproduced, and how the user can interact with the ongoing presentation. The relationship that is created between instances of these classes forms the structure of the presentation. There are several different types of class in the MHEG model, e.g. content classes or behavior classes, action classes, link classes, user input classes etc. [0016] The separation of underlying techniques (due to their complexity) yields to an unfortunate separation of media description in a multimedia hypermedia document. [0017] As in the case for coding, several other cross platform multimedia standards have been established e.g. the well known hypertext markup language (HTML) or meta descriptions like Standard Generalized Markup Language (SGML) or Extensible Markup Language (XML). [0018] Linked content can be in different formats: text, HTML, images, video or audio, slides and many others. Content standards depend mostly on the plug-ins running on the user's browser, going images to complex media formats (mp3, wave, midi, Real Player). [0019] Technically, the enrichment process does not affect the temporal media like video, since the link structure is described independently. At a conceptual level a hyper-video is the aggregation of a digital video and the linked informative structure. Technically it is realized by the original video decorated with (synchronized) links in a separate (enveloping) description. [0020] Two specifications are vying to be the baseline protocol for multimedia exchange. The first is commonly known as MHEG (mentioned above), the second is DVB-MHP (digital video broadcast multimedia home platform). [0021] ISO defines a family of MHEG standards, from MHEG-1 to MHEG-7, that allow multimedia objects to be distributed in a client-server architecture across a variety of platforms. MHEG-5 is a streamlined, application-specific version of MHEG-1 that embeds an MHEG boot application in the MPEG-2 stream. The boot application is a self-contained interpreting media object. [0022] The DVB-MHP spec inserts an abstraction layer between applications and digital TV terminals. This allows applications to be carried over any compliant network, be it cable, terrestrial, or satellite, to a wide range of terminal types.
