2. SOFTWARE UPDATE DESCRIPTION
1.1. 17MB38 Analog Part Software Update With Bootloader Procedure
1.1 The File Types Used By The Bootloader
All file types that used by the bootloader software are listed below:
1. The Binary File : It has “.bin” extension and it is the tv application. Its size is 1920 Kb.
2. The Config Binary File : It has “.cin extension and it is the config of the tv application.
Its size may be 64 Kb or a few times 64 Kb.
3. The Test Script File : It has “.txt” extension and it is the test script that is parsed and
executed by the bootloader. It don’t have to be any times of 64 Kb.
4. The Test Binary File : It has “.tin” extension and it is used and written by the test
groups. It is run to understand the problem part of the hardware.
Alltough a file that is used by the bootloader can be had any one of these extensions, its
name has to be “VESTEL_S” and it has to be located in the root directory of the usb
device.
1.2 Usage of The Bootloader
1. The starting to pass through : The chassis is only powered up.
2. The starting to download something : When chassis is powered up the menu key has to
be pushed.Before the chassis is powered up and if any usb device is plugged to the usb
port, the programme is downloaded from usb firstly.
Any usb device is plugged to usb port , user must open hyperterminal in the pc and
connect pc to chassis via Mstar debug tool and any one of scart,dsub9 or I2c connectors.
Serial connection settings are listed below:
- Bit per second: 115200
- Data bits: 8
- Parity: None
- Stop bits: 1
- Flow control: None
In this case the bootloader sofware puts “C” character to uart. After repeating “C”
characters are seen in the hyperterminal user can send any file to chassis by selecting
Transfer -> Send File menu item and choosing “
1K Xmodem” from protocol section.
Figure 1. The Sample Output Before Sending The File
2. EEProm update
To Update eeprom content via uart scart,dsub9 or i2c with Mstar tool can used.
Serial connection settings are listed below:

6. MPEG-2/MPEG-4 DVB Decoder – NEC EMMA3SL
6.1. General Description
The MC-10085/86/87/88 devices, EMMA3SL/HD, are part of the third generation of
multimedia processors based on NEC’s Enhanced MultiMedia Architecture (EMMA™). This
device provides nearly all the functionality required to realise a high performance and costeffective integrated digital TV.
NEC EMMA3SL integrates the functions of a TS de-multiplexer, a DMA controller, MPEG2,
H.264 (MPEG-4 part 10) and VC-1 video decoders, an audio processor, graphics and display
engines, a video encoder and DAC, and various interfaces to support peripheral modules.
The device has been designed with a memory interface using glueless logic which supports
DDR2 SDRAM. The MC-10085/86/87/88 incorporate a processor, two main buses and a
peripherals bus. The processor is a MIPS32 24KEc core and can access all modules within the
device.

7 SIL9185 3:1 HDMI 1.3 Switch
7.1 General Description
The SiI9185A is the first generation of TMDS switch device supporting Revision 1.3 of the
HDMI Specification (HDMI Consortium; June 2006). With three HDMI inputs and a single
output, the SiI9185A provides a low-cost method of adding additional HDMI ports to the
latest Digital TVs. New DTVs can easily connect to the many HDMI sources coming on
the market, including DVDs, STB, game consoles, PCs, camcorders, and digital still
cameras. The SiI9185A is a fully HDMI compliant device providing a simple, lowcost
method of retransmitting protected digital audio and video, giving end-users a truly alldigital experience. Built-in backward compatibility with DVI 1.0 allows HDMI systems to
connect to any DVI 1.0 source. The SiI9185A provides additional integrated features to
help lower system cost and provide enhanced features to the end consumer. To lower
system cost, the SiI9185A provides a complete solution for switching sink-side HDMI
signals. This includes DDC switching, individual HPD control, and 5V sense. The addition
of these features eliminates additional external components, helping to lower cost. For
source-side applications, the SiI9185A DDC switching can be bypassed with an external
4-channel I2C-bus switch(e.g., Texas Instruments PCA95445) to allow clock
stretching.
