2、idering a) that flat-screen television display technology is now mature and affordable; b) that large screen displays have been demonstrated to be suited to stereoscopic2television viewing; c) that digital television systems are now in widespread use; d) that digital television encoding offers far g

3、reater scope for stereoscopic television systems than does analogue television encoding; e) that digital stereoscopic television encoding offers far greater monoscopic compatibility than does analogue stereoscopic television encoding; f) that a significant time has elapsed since previous ITU-R studi

4、es on stereoscopic television and that there may have been significant advancements in this time; g) that ITU- R has established a range of television broadcasting systems in Recommendations ITU-R BT.601, ITU-R BT.709 and ITU-R BT.1201 for television production; h) that ITU-R has established a famil

5、y of Recommendations for Large Screen Digital Imagery; j) that ITU-R has two existing Recommendations on Stereoscopic television, namely Recommendations ITU-R BT.1198 and ITU-R BT.1438; k) that previous ITU-R studies on stereoscopic television pre-dated the widespread implementation of digital telev

6、ision and that digital technology may now offer significantly expanded options for stereoscopic television implementation, decides that the following Question should be studied 1 What stereoscopic systems are now available, or are under development, for television production, post-production, distri

7、bution and emission? 2 What are the relative merits of each system in each of these areas and in various viewing contexts? _ 1This Question should be brought to the attention of the International Electrotechnical Commission (IEC). 2Stereoscopic image systems allow the illusion of depth to be present

8、ed using a flat display. - 2 - 3 How compatible are the various systems and at what point in the production chain must they diverge from a common format? 4 What common stereoscopic programme format/s can be used to maximise compatibility between stereoscopic systems? 5 What parameters from Recommend

9、ations ITU-R BT.601, ITU-R BT.709 and ITU-R BT.1201 for television production are applicable to the development of stereoscopic television broadcasting system(s)? 6 How the development of stereoscopic television broadcasting system relates to the specifications of Large Screen Digital Imagery; 7 How

10、 can compatibility of stereoscopic television technology with monoscopic television systems be maximised? 8 What criteria should be used to assess the performance of stereoscopic television systems and what should be the minimum standard of performance under these criteria? 9 Is there a compatible s

11、tereoscopic television system with a clear performance advantage, a clear compatibility advantage and/or a clear cost advantage which can be recommended for general use? 10 Is any stereoscopic performance compromise necessary to maintain monoscopic compatibility and if so, what is its extent and how

12、 is it perceived by the audience? 11 Is any monoscopic performance compromise necessary to incorporate compatible stereoscopic signals in a digital television system and if so, what is its extent and how is it perceived by the audience? further decides 1 that the results of the above studies should be addressed to prepare (a) new Recommendation(s) and Reports or Handbooks; 2 that the above studies should be completed by 2008.
