44、 with 16:9 picture-ratio and greater than 9,5V is an active 4:3 source). All signals from the digital board (“D_R”, “D_G”, “D_B”, D_C”, “D_Y” and “D_CVBS” are routed to the proper inputs of the STV6618 for amplification and driving purpose before they can be seen on the appropriate Scart outputs. In

45、 case of EPG the signals from the digital board are routed through the EPG board where the selection between digital board video or EPG OSD is taken. The “D_CVBS”- and the “D_Y”-line are passing a 6 dB- amplifier and driver-IC 7410 and are then routed to the CVBS- Cinch and Y/C-out rear. The chroma

46、signal for this Y/C out is coming from the STV6618 - which makes the 6 dB- amplification - and a driver 7406 in between. The detection of the picture ratio information on the Y/C-input front is made by measuring the DC-level on the Chroma signal via analog input of the CC-P (“WSFI”-line). In case th

47、e level is higher than 3,5V the input signal is a 16:9 source. If the level is lower than 2,4V the picture ratio is 4:3. For generation of the appropriate DC-voltage on the Y/C-out rear the “WSRO”-line is controlled via pin 18 of 7408 by the CC-P (Pin 18 set to low means 4:3, pin 18 set to high dete

48、rmines 16:9). The control of the switching voltage (Pin 8 of Scart 1) is done via 3-level-pin (nr.2) of the STV6618 7408 and the transistors 7405, 7407 3701, 3702 and 3703 are used for level adaptation (5V to 3V3). Pos 7700 is a driver for the video signal. The sound demodulation is realized by the MSP34x5 7600, which is also fully controlled via I2C-bus by the CC-P (determination of bandwidth, amplitude, standard, .). The audio signals are available at pin 30 and pin 31 of 7600 and fed as “AFER”- may be gated or used in a burst fashion. 27ISDATASerial Input, MSB first, contain
