    Fast Blanking 75R input and output impedance. This control voltage allows devices to over-ride the composite video input with RGB inputs, for example when inserting closed caption text. It is called fast because this can be done at the same speeds as other video signals, which is why it requires the same 75R impedances.
  • Page 13: Circuit Description

    13. CIRCUIT DESCRIPTION 13.1. POWER SUPPLY • Socket PL1 is the 220VAC input. • 2.5A fuse F1 is used to protect the device against short circuit. • Line filters and capacitors L1, C1, L5 and L6 are used to block the parasitic coming from the mains. They also prevent the noise, produced in the circuit, from being injected to the line.
  • Page 14: Sofware Uptate

    • Socket PL2, which is coming from the mainboard, transmits RED, GREEN, BLUE and VIDEO signals to SCART over the buffer stage. • LUMA and CHROMA signals of S-Video are transmitted to S-Video socket via transistors Q11 and Q13 respectively. 14.
