6.13D AV Coding

After the Draft Call for Proposals on multiview video coding, as issued by the Hongkong meeting (N6910), a decision was to be made to proceed with the Call according to the status of availability of suitable test sequences (including camera parameters). Before and at the Busan meeting, new test sequences were provided by 6 companies. Therefore, it was decided to proceed and issue a Preliminary CfP (N7094). The available material was extensively reviewed and it was decided to define four different scenario classes, including rectified and non-rectified sets, linear and half-circle camera arrangements:

• 
  linear setting, calibrated and registered (rectified) for 3D display
  
• 
  linear 2D setting, calibrated and registered (rectified) for 3D display
  
• 
  half circle setting, calibrated
  
• 
  linear convergent setting, (no preprocessing).
  

The rectified sets are useful for applications supporting view adaptation on stereoscopic 3D displays (t.b.d. whether stereo displays will be used during the tests), while other scenarios would rather support look-around views. As the new test sequences were only available shortly before the Busan meeting, it was not yet possible to define the actual rates at which the CfP results will have to be submitted. This will be tested within the AHG period until the Poznan meeting, taking into account the results gained by AVC anchors with appropriate settings (preliminary definition of settings are given in the Pre-Call, with indication that they will be refined). A detailed description of the evaluation procedure, material to be sent by proponents etc. is also provided.
