3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
3DTV: DVB frame compatible plano-stereoscopic three-dimensional television
3DTV compliant IRD: IRD that is both 3DTV cognisant and that is able to render frame compatible
plano-stereoscopic 3DTV video content correctly, being either a 25 Hz plano-stereoscopic 3DTV IRD or a 30 Hz
plano-stereoscopic 3DTV IRD as defined in TS 101 154 [4]
3DTV cognisant IRD: IRD that is able to identify frame compatible plano-stereoscopic 3DTV services via the
corresponding Service Information (DVB-SI), and the frame compatible plano-stereoscopic 3DTV video format, but
that is not necessarily able to render frame compatible plano-stereoscopic 3DTV video content correctly
3DTV incognisant IRD: IRD that is not able to identify frame compatible plano-stereoscopic 3DTV services via the
corresponding Service Information (DVB-SI), nor the frame compatible plano-stereoscopic 3DTV video format
captions: text and visual elements intended to be overlaid on the picture as an optional feature, e.g. subtitles for foreign
language source material, or for viewers with impaired hearing
disparity: difference between the horizontal positions of a pixel representing the same point in space in the right and
left views
NOTE: Positive disparity (horizontal right coordinate greater than horizontal left coordinate) implies a position
behind the plane of display, and negative disparity implies a position in front of the display.
Frame Compatible (FC): arrangement of the Left and Right images in a spatial multiplex which results in an image
which can be treated like a normal HDTV image by the receiver demodulator and compression decoder
HD ready, HD 1 080: labels authorized by Digital Europe to classify HDTV TV displays
natural binocular viewing: process of viewing with two eyes, as is done by most people
pixel arrangements: arrangement of horizontal and vertical image samples
NOTE: This has an impact on vertical, horizontal, or diagonal resolution.
plano-stereoscopic: three-dimensional picture that uses two single pictures, Left and Right, displayed on a single plane
surface (the TV screen in the case of 3DTV)
polarisation planes: optical filter system used to direct the left and right eye images to the appropriate eye
Side-by-Side (SbS): arrangement of the Frame Compatible spatial multiplex such that the horizontally anamorphic Left
eye picture is placed in a spatial multiplex to occupy the first half of each line, and the Right eye picture is placed in the
spatial multiplex to occupy the second half of each line
Service Compatible (SC): arrangement of the Left and Right images such that an existing HDTV receiver is able to
extract a 2D version of the video content from a frame compatible plano-stereoscopic 3DTV service
service guide: usually information on programme choice displayed on the screen, and often derived from now and next
information broadcast in the multiplex
simulcast: parallel broadcasting of the same programme, often in different forms or formats
titles: usually all forms of text and graphics that appear on top of a TV scene or another background, intended to be
visible for all TV viewers
Top-and-Bottom (TaB): arrangement of the Frame Compatible spatial multiplex such that the vertically anamorphic
Left eye picture is placed in the spatial multiplex to occupy the first (top) half of a single HD video frame, and the Right
eye picture is placed in the spatial multiplex to occupy the second (bottom) half of a single HD video frame
