Fernsehempfänger für Fernsehsystem hoher Auflösung
摘要
Disclosed is a television receiver for extended definition television, the receiver carrying out scanning line interpolation in a way that eliminates picture shift on the screen and ensures normal display when supplied with a non-standard video signal having a scanning line count of other than 262.5 per field. The television receiver comprises scanning line interpolation means, normal video signal detection means and interpolation control means. The scanning line interpolation means effects scanning line interpolation using either data in the current field or out-of-field data as per the result of motion detection in the picture. The normal video signal detection means distinguishes the normal video signal from other signals by detecting the number of the scanning lines involved. The interpolation control means causes the scanning line interpolation means to effect scanning line interpolation using only the inside-field data if the supplied signal is a non-standard signal. <IMAGE>
