Analogue Video Processing (all versions)
·
·Internal (switchable)
·Switchable group delay correction and sound trap (with switchable centre frequency) for the demodulated CVBS signal
·DVB/VSB IF circuit for preprocessing of digital TV signals.
·Video switch with 3 external CVBS inputs and a CVBS output. All CVBS inputs can be used as
·Automatic Y/C signal detector
·Adaptive digital (4H/2H) PAL/NTSC comb filter for optimum separation of the luminance and the chrominance signal.
·Integrated luminance delay line with adjustable delay time
·Picture improvement features with peaking (with switchable centre frequency, depeaking, variable positive/negative peak ratio, variable
·Switchable DC transfer ratio for the luminance signal
·Only one reference (24.576 MHz) crystal required for the TCG
·
·Internal
·Indication of the
·Linear RGB/YPBPR input with fast insertion.
·YUV interface. When this feature is not required some pins can be used as additional RGB/YPBPR input. It is also possible to use these pins for additional CVBS (or Y/C) input (CVBS/YX and CX).
·Tint control for external RGB/YPBPR signals
·Scan Velocity Modulation output. The SVM circuit is active for all the incoming CVBS, Y/C and RGB/YPBPR signals. The SVM function can also be used during the display of teletext pages.
·RGB control circuit with ‘Continuous Cathode Calibration’, white point and black level
·Contrast reduction possibility during
·Adjustable ‘wide blanking’ of the RGB outputs
·Horizontal synchronization with two control loops and
·Vertical
·Vertical driver optimized for
·Horizontal and vertical geometry processing with horizontal parallelogram and bow correction and horizontal and vertical zoom
