? Blue Stretch
? Green Enhancement
? Black Stretch
? 32-bins histogram
? Electrical Local Doming Protection
Picture in Picture / Double window
? Requires external memory to be connected to SDRAM interface
? Second input through second color decoder. Can be selected to be either main or sub.
? YCrCb storage in 4:2:2 format. 8 bits per component. Dithering adopted to have 9 bits effectively.
? No joint line/crossover errors
? Supporting Double Window displaying both a PAL (50 Hz) and an NTSC (60 Hz) signal.
? Double window text. Displaying a TeleText page next to a TV broadcast. This feature is functional without
the external Memory in 50 Hz mode.
? For proper aspect ratio of Double Window display on 4/3 screen vertical scaling by deflection can be
adopted
Scan Rate Conversion
? This requires external memory connected to SDRAM interface
? Line flicker reduction
? Full interlaced performance (provided sufficient memory )
Video H/V Scaling
? Horizontal Panorama/customer defined Scaling in video path (not affecting graphics)
? Vertical Scaling by vertical deflection
Audio Base band Switching and Interfaces
? 5x Analogue outputs (Left, Right, Subwoofer, Centre and Surrou nd speaker)
? 1x Left and Right Head Phones output
Sound Demodulator/Decoder
? Two FM/AM Demodulator channels with programmable mixer frequencies and four different filter
bandwidths:
- Multi-standard FM demodulation (B/G, D/K, I, M and N standard)
- Optional AM demodulation (L/L? standard)
- FM pilot carrier present detector (for A2 sound systems)
? FM-A2 Decoder:
- Detection of ID signal for second carrier
- Decoding for three analog multi -channel systems (A2, A2+ and A2*) and satellite sound
- Identification A2 systems (B/G, D/K and M standard)
- Supporting Korean 2SC standard
? BTSC Stereo/SAP Decoder:
- M/BTSC and N standards supported
- Processing of MTS/MPX signal
- Detection of pilot carrier with pilot lock indicator
- AM demodulation of stereo sub -carrier
- Detection of SAP sub carrier
- SAP decoder
- FM demodulation of SAP carrier (without dbx?) simultaneously with stereo decoding, or mono plus
SAP with dbx?
- dbx? noise reduction on either (L -R) or SAP signal
? Japan MTS Decoder:
- Processing of M PX signal
- Detection of the Identification signal
- FM demodulation of sub -carrier for stereo or bilingual reproduction
? NICAM demodulator and decoder (B/G, I and L/L? standard):
- DQPSK demodulation for different standards, simultaneously with 1 -channel FM demodulation
- NICAM decoding
? Auto Standard Detection Mode (ASD)
? Demodulator Decoder Easy Programming (DDEP)
? FM-Radio decoder
? Identification circuit for all standards
