Abstract (en)
[origin: WO9826591A2] Transmission of teletext in a digital television format is disclosed. The video information is transmitted in the conventional YUYV format. For teletext transmission, the U and V sample periods are used to transmit additional luminance samples. Accordingly, teletext is transmitted in YYYY format, which in the CCIR 601 system corresponds to a 27 MHz sampling frequency. Teletext recovery is much more reliable.
