Quincunx Tech Note by Sensio

SENSIO (Montreal, Canada) is pleased to announce that the technical notes for the application of the DVB-3DTV specification to the SENSIO® Hi-Fi 3D format are now available for download from our website. Titled "CONFIGURATION FOR QUINCUNX SIGNALLING IN DVB-3DTV & HDMI 1.4A", the DVB-3DTV specification details the delivery system for frame compatible plano-stereoscopic 3DTV services, enabling service providers to utilize their existing HDTV infrastructures to deliver 3DTV services that are compatible with 3DTVs already in the market.

This system covers both use cases of a set-top box delivering 3DTV services to a 3DTV via an HDMI connection, and a 3DTV receiving 3D services directly via a built-in tuner and decoder, and the application notes will enable the broadcast chain to deliver SENSIO® Hi-Fi 3D optimally.

The documents explains how the SENSIO side-by-side quincunx format works. This 3DTV signalling format is one of those in the H264/AVC video coding that can be carried out over HDMI1.4 connections. Among the advantages of quincunx subsampling, you find a better compromise between X and Y resolution losses.

Check visually the differences betweeen pure side-by-side and quincunx in the video here under (of course, select 1080p format and watch in full screen).

Note that the quincunx format is also detailed in the new book by Benoit Michel "La Stéréoscopie Numérique" edited by Eyrolles in French this week.
