Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is responsible for the standardization of radio and television receivers.

20、an Broadcasting Union CH-1218 GRAND SACONNEX (Geneva) Switzerland Tel: +41 22 717 21 11 Fax: +41 22 717 24 81 The Digital Video Broadcasting Project (DVB) is an industry-led consortium of broadcasters, manufacturers, network operators, software developers, regulatory bodies, content owners and other

21、s committed to designing global standards for the delivery of digital television and data services. DVB fosters market driven solutions that meet the needs and economic circumstances of broadcast industry stakeholders and consumers. DVB standards cover all aspects of digital television from transmis

22、sion through interfacing, conditional access and interactivity for digital video, audio and data. The consortium came together in 1993 to provide global standardisation, interoperability and future proof specifications. ETSI ETSI TS 101 600 V1.1.1 (2012-05)6Introduction A plano-stereoscopic system c

23、reates a 3D illusion for the viewer by delivering two images (left and right) that are seen simultaneously by the left and right eyes. This can be achieved by various techniques on a TV-set, such as shutter glasses, polarizer glasses and others. Since 2010 many 3D-enabled consumer products have appe

24、ared on the market starting with Blu-ray players and TV sets. DVB took into account the need to support planoscopic 3DTV for broadcast services and developed a specification to define the delivery system for plano-stereoscopic 3DTV services, that are compatible with 3DTV capable displays that alread

25、y available in the market 3. GEM 1 based TV middleware specifications are adopted in different markets. The present document specifies an extension to the DVB GEM middleware with a new horizontal 3D profile. This 3D GEM profile ensures that interactive applications and graphics are aware of 3D conte

26、nt and can handle drawing situations, where the application graphics are superimposed to 3D movie content. ETSI ETSI TS 101 600 V1.1.1 (2012-05)71 Scope The present document specifies the extensions to the DVB GEM 1 middleware to enable applications that are aware of frame compatible plano-stereosco

27、pic 3DTV services. This is achieved with a new horizontal 3D profile which can be applied to all GEM targets. The 3D profile extends the display model and presentation APIs, to enable additional 3D display modes and drawing functions, with varying capabilities. For the more capable 3D modes a new dr

28、awing API is introduced, which is a stereoscopic extension of the java.awt.Graphics2D API set. On devices with hardware support for accelerated 3D graphics based on OpenGL ES, the present document specifices an additional 3D mode, which enables the rendering of a 3D volumetric scene to a stereoscopi

29、c display. On these devices Open GL ES based drawing is also available for 2D display modes. NOTE: Although the present document defines the 3D profile for the 1.3 version of the GEM specification, it is also applicable for previous GEM versions. 2 References References are either specific (identifi
