Patent GB-2240230-A (GB)
Title: Field-rate upconversion of television signals prior to bandwidth compression
Inventor: CHILDS IAN
IPC: H04N7/015
Filed: 1990-01-18
Abstract: To alleviate problems experienced with field rate upconversion, a high definition source is field rate upconverted (160) prior to bandwidth compression (120, 122, 124, 125). Bandwidth compression is performed by a number of different methods, at least one of which is applied to the upconverted source signal. The branch or method of bandwidth compression transmission is selected in accordance with a control signal responsive to picture content. Prior to transmission of the upconverted bandwidth compressed signal, the signal is collapsed to the transmission field rate and the samples rearranged into a quincunxial configuration (at 132).
