Presents a discussion of transmission media and picture displays for home cinemas and for professional cinemas. Various types of projectors are compared, and tables of video and graphic CIF formats, dimensions, weight, light output (up to 10000 lumens), and resolution classes (up to SXGA-HDTV) are presented. The paper refers to the problem of noise generated by the fans required for projector cooling. It also explains how white light is split into RGB using a prism or a filter wheel. The paper also refers to LCOS (liquid crystal on semiconductor) display panels. Problems of de-interlacing and synchronisation and of testing, are stated. It is concluded that fully electronic cinemas are now possible.
