feature box. The outgoing signals of the feature box are on double the line frequency and also the line deflection is running on 2fh. The TDA9321H contains the following functions: Sound IF, Vison IF and Demodulation, PAL / SECAM / NTSC colour decoding, Sync processing, Source switching and RGB to YUV matrix. All out going signals are converted into YUV signals which are fed to the feature box. This box converts the YUV signals to YUV signals with the double line frequency and double field frequency or single field frequency in case of progressive scan mode. The output YUV signals from the feature box are fed to the TDA933x H. The TDA933x H contains the YUV to RGB conversion, the RGB processing and deflection processing of the set. The output signals from the TDA933x H drive the RGB output stages, vertical deflection and horizontal deflection. It is also possible to feed to the TDA9332H a VGA signal from an external source (PC). Philips Semiconductors GTV4000 2Fh TV receiver with TDA9321H and TDA933x H Application Note AN98079 CONTENTS 1.
