R&D Report 1966-06 : Subjective assessments of the portrayal of motion produced by simulations of field-store standards conversion R.E. Davies, S.J. Lent, M.T.A. Salter It is shown that the process of television standards conversion involving a change of field frequency degrades the portrayal of movement in the scene by introducing a jerky motion to certain types of movement. Experiments are described which show that in order to provide satisfactory portrayal of motion, when converting...

R&D Report 1973-06 : Equipment for the transfer of digital video signals to paper tape C.K.P Clarke A digital computer can be used to simulate processing methods for the bit-rate reduction of digital television. To assess such methods, television signals must be converted to a form compatible with computer data-handling systems. This report describes equipment for transferring monochrome pulse-code modulation signals derived from a slide scanner to punched paper tape. One eight-bit word is...

R&D Report 1962-01 : Tests of three systems of bandwidth compression of television signals G.F. Newell, W.K.E. Geddes This report describes an investigation into three similar methods of reducing the bandwidth required for the transmission of television pictures. The three methods all involve the isolation of the essential brightness changes in the picture; these are redistributed to occur at a uniform rate for transmission. A second signal must be transmitted in order to allow correct...
