Abstract
Recent discussions with a number of leading Cable Television broadcasters has indicated a willingness to include 3D capabilities in their role out of digital television services. Such a service would represent a landmark in the evolution of 3D. While this will provide a tremendous stimulation to numerous fledgling 3D industries throughout the world, the development of a digital 3D broadcast architecture that would meet the stringent requirements of the Cable companies will not be a simple exercise. During discussion, the Cable companies proposed the following specification for a digital Cable 3D service: 1) The 3D service must be totally 2D compatible; 2) The fact that 3D is being transmitted should not be detectable by the 2D viewer and not affect the 2D service in any way; 3) No additional bandwidth will be required for the 3D service; 4) The 3D service must be totally compatible with all existing and future 2D systems and equipment; 5) The 3D system must cater for existing stereoscopic display system and future 'multiple view' displays; 6) Unlimited supply of high quality, low cost, 3D material. Additionally, should the 3D service prove to be economically viable then: 7) The service must be capable of being upgraded to accept stereoscopic video images. In the case of 7, then 2D compatibility would not be required and a number of the other restrictions would be relaxed. An architecture that will meet these requirements is described.
