    The image post-processing unit can scale the stored image (horizontally and vertically with scale ratios of 1/2 to 2) and shift it with 1/4 pixel resolution. Then, it can enhance the image and pad it with background colour. In addition, the VPU has a DVD sub-picture decoding unit. The sub-picture is blended with the enhanced image.

    9. PLL - P ROCESSING LOCK ENERATION The PLL unit consists of three sub-units: The PLLa unit generates (under ADP control) the audio interface master clock (AMCLK). It has 13 bits of frequency multiply and divide factors. Its input can be a separate clock generator or be (externally) tied to the clock generator or crystal input to the processing clock PLL (see below).

For longer lengths, shielded co-ax cable become essential. Scart Signals: Audio signals 0.5V RMS, <1K output impedance, >10K input impedance.

    CIRCUIT DESCRIPTION 12.1 POWER SUPPLY: • Socket PL2 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.
  • Page 17 • TOTX176 is used for laser output. • For coaxial audio output SPDIF is used. • Q4, Q5, Q6, Q7, Q8 and Q9 transistors are to mute the audio outputs while switching the state of the unit(power on/off) • There are two op-amps in U9, U12 and U14. They are used for left,right,rear left and right, subwoofer center audio channels.
