Mobile TV (DVB-SH) will use in most of developed countries in the near future

The mobile TV (DVB-SH) will use direct broadcast satellite to spread to the surface of the earth.
User receive mobile TV (DVB-SH) use ordinary antenna,not need parabolic antenna and LNB,can receive.
The mobile TV (DVB-SH) will use Ku band for upstream,and use S band (above 2.5Ghz) or C band for downstream.
The mobile TV (DVB-SH) will use 8PSK modulation, and the video stream use H.264 (AVC)coding,also include SDTV and HDTV, the audio stream use AAC coding.
The mobile TV (DVB-SH) will support traditional direct broadcast TV channel, Push VOD, radio and any other data stream broadcasting.
In the near future,many of new model phones will be integrated Mobile TV (DVB-SH) receiver function.
Maybe some of middle-grade and high-grade tabletpc will be integrated Mobile TV (DVB-SH) receiver function.
In most of developed countries,will have a few of free TV channel (not encryption),user can be free to watch.

Forecast: about some manufacturers in future

Thomson will go bankrupt.
HITACHI will go bankrupt.
Panasonic will go bankrupt.
SONY will go bankrupt.
NEC will go bankrupt.
SHARP will go bankrupt.
SANYO will go bankrupt.

Fujitsu will buy SHARP's LCD TVset business.
Fujitsu will buy part of NEC's chips business.

SIEMENS will produce phone, tabletpc, LCD TVset in future.

These company will have part of HDMI patent in future:
Fujitsu, CASIO, SIEMENS and PHILIPS
Because in before Thomson, HITACHI, Panasonic, SONY have part of HDMI patent,but these company will go bankrupt,so Fujitsu, CASIO, SIEMENS and PHILIPS will buy these part of HDMI patent.

Forecast: some manufacturers will produce chips for phones, tabletpc and smart TVset

These company will produce ARM or MIPS of instruction set chips,for phones, smart TVset and middle-grade and high-grade tabletpc.Some of ARM chips deisgned for MS-Windowsphone.  These manufacturers:
AMD
Toshiba
Fujitsu
CASIO
SIEMENS
PHILIPS
Lenovo

These company will produce ARM or MIPS chips for all kinds of tabletpc, phones and smart TVset:
(Also some of ARM chips deisgned for MS-Windowsphone.)
VIA
Realtek
MediaTek (MTK)
ALi Corporation (Maybe ACER will buy ALi Corporation.)(Maybe No chips support MS-Windowsphone)
SIS (Maybe HTC will buy SIS.)(Maybe No chips support MS-Windowsphone)
Sunplus  (Maybe No chips support MS-Windowsphone)
Pioneer Corporation
Telechips (Maybe No chips support MS-Windowsphone)
CREATIVE (Maybe No chips support MS-Windowsphone)
Sigma   (Maybe No chips support MS-Windowsphone)
ATMEL   (Maybe No chips support MS-Windowsphone)
National Semiconductor
Texas Instruments (TI)
STMicroelectronics (Maybe No chips support MS-Windowsphone)

LCD monitor in future

LCD monitor in future

The driver chip of LCD monitor ,all have these feature:
Support any kinds of common LVDS LCD screen.
Have some jumpers,to set which kinds of LCD screen (single or double, 6bit or 8bit, the resolution of the LCD screen)
The resolution of LCD screen,can support max to 1920*1080 pixel
Also have jumpers,to set the voltage of LCD screen
Support Dual channel DVI input interface (24pin DVI input)(also compatible 18pin DVI input)
Have one VGA input port (have a RGB video ADC unit in the driver chip)
Support multiple colors OSD display by hardware
Have power management function
If the driver chip not receive any signal,can auto shutdown the light source of the LCD screen,to save electricity

LCD monitor driver chip support HDMI:
The different as above driver chip:
If the driver chip not support 3D LCD monitor,support 1920*1080 pixel only. The jumpers,can only set these property of LCD screen (single or double, 6bit or 8bit, the voltage of LCD screen)
If the driver chip support 3D LCD monitor(or support more higher resolution than 1920*1080),can use the jumpers,to set the resolution of the LCD screen.
All of support one HDMI input port,many of support HDMI 1.4
All of support DHCP function
All support HDMI audio function,so have a audio DAC unit in the driver chip,support 2 channel audio,max to 192Khz 32bit per channel,the signal to noise ratio all higher than 90db.
Also have one Dual channel DVI input interface (24pin DVI input)(also compatible 18pin DVI input)
Support YUV (YCbCr,whether PAL or NTSC) color mode convert to RGB color mode in real time,max to 1920*1080 60fps or higher resolution(if the driver chip support higher resolution than 1920*1080,or support 3D video)

Some of driver chip support YCbCr, CVBS video and analogy TV receive:
The different as above driver chip:
Have a video ADC unit(support YCbCr and CVBS video) in the driver chip.
Support one YCbCr and CVBS video 2 in 1 port,and have other two CVBS video input port
Support YUV (YCbCr,whether PAL or NTSC) color mode convert to RGB color mode in real time,max to 1920*1080 60fps or higher resolution(if the driver chip support higher resolution than 1920*1080,or support 3D video)
Can connect a analogy TV tuner,to support analogy TV receive
Support infrared remoter receive

This kind of driver chip,support RGB and TTL interface of LCD screen:
Many of this kind of driver chip,used for small size LCD monitor (many of smaller than 10inch)
The different as above driver chip:
Support any kinds of common LVDS, TTL and RGB interface of LCD screen
Support the resolution of LCD screen max to 1920*1080
If use RGB interface of LCD screen,the resolution can be lower than 640*480
If the resolution of LCD screen lower than 640*480,can still use VGA input,the VGA signal can be 640*480, 800*480 or 800*600,but will be auto reduced the resolution to adapt the LCD screen
Support VGA, YCbCr and CVBS video input(one YCbCr and CVBS video 2 in 1 port,and have other two CVBS video input port)
Not support HDMI and DVI input
Support YUV (YCbCr,whether PAL or NTSC) color mode convert to RGB color mode in real time,max to 1920*1080 60fps
Can connect a analogy TV tuner,to support analogy TV receive
Support infrared remoter receive

Finished product of LCD monitor:
All of LCD monitors if the size under 21 inch (the resolution under 1920*1080),use the common shell
Many of large size LCD monitor (Greater than or equal to 21 inch),still use the common shell,but some of use special mold
If LCD monitors' size under 21 inch (the resolution under 1920*1080),many of not have DVI port
If LCD monitors' size greater than or equal to 21 inch (the resolution greater than or equal to 1920*1080),many of have one HDMI port, one VGA port, one 3.5mm audio output port, and a DC 12V powersupply port. But some of have one 24pin DVI port, one VGA port, and a DC 12V powersupply port,not have HDMI port.
All of the LCD driver board(the drive chip on the board),use common PCB design
Even some different brand of LCD driver chip,the PCB design will be still same
