1 INTRODUCTION
17MB12 Main Board is a single board IDTV project, consists of Micronas and NEC
concept. VCT_Pro and Emma2LL are used as controller for TV and IDTV side
respectively. VCT_Pro is capable of handling Audio processing, video processing,
motion adaptive upconversion (MAU), Scaling-Display processing and FPD control
(DPS), unified memory for audio video and Text, 3D comb filter-PC connectivity, OSD
and text processing. Emma2LL is capable of handling MPEG1 and MPEG2 decoding
and provide nearly all the functionality required to realise a high performance and cost-
effective digital set-top box or integrated digital TV.
TV supports DVB-T reception and following analog receptions PAL, SECAM, NTSC
colour standards and multiple transmission standards as B/G, D/K, I/I’, and L/L’
including German and NICAM stereo.
Sound system output is supplying 2x8W (10%THD) for stereo 8speakers.
Supported peripherals are:
1 RF input VHF1, VHF3, UHF @ 75Ohm
1 FAV input
2 SCART sockets
1 SVHS input
1 Stereo Headphone input
1 YPbPr
1 PC input
2 HDMI input
1 Stereo audio input for PC and YPbPr
1 Stereo audio output
1 Subwoofer
1 Spdif
2 TUNER
Vertical mounted digital tuner is used in the product, which is suitable for analog
reception with DRX-A. The tuning is available through the digitally controlled I2C bus
(PLL). Below you will find info on the Tuner in use.
2.1 General description of DTT71307:
The DTT 755XX is designed for digital terrestrial reception in VHFIII and UHF,
compliance with the European digital terrestrial standard ETS 300 744. In addition the
tuner covers all analog channels from 44,25 MHz to 863,25 MHz. It is a two band
concept VHF and UHF,with VHF switch between VHF low (VHF I) and VHF high (VHF
III).
2.2 Features of DTT71307:
•VHF I/III/ UHF frequency range
•Antenna loop through (optional)
•Low phase noise
