The document discusses the pros and cons of different formats for transmitting 3D television broadcasts. It considers delivering only the 3D-TV version, which allows for larger flexibility in production but requires more transmission capacity. Alternatively, simulcasting a 2D version of the 3D-TV broadcast would be more spectrum efficient and cheaper to produce, but could impose the 3D shooting and editing style on 2D viewers. Overall, the document presents issues around compatibility, formats, and transmission requirements for enabling 3D broadcasts.
