does cause unacceptable interference to radio or TV reception, which can be determined by turning the
equipment off and on the user is encouraged to try to correct the interference by one or more of following
measures:
1. Reorient or relocate the receiving antenna
2. Increase the separation between equipment and receiver
3. Connect the into an outlet on circuit different from that to which the receiver is connected
4. Consult the dealer or an experience radio/TV technician for help

TRIDENT 3D DPTV
POSION IN IP BOAD (U10).
The chip utilizes two kind of resource: memory and register. the DPTV use a 8 bit address
Architecture, and therefore has 256 ports available. To across all the memory Space and
register efficiently. please refer to following instructions:
6.5.1.The register are divided into pages, each pages contains at most 224 (E0 HEX) register (0~DF)
6.5.2.The pages control register FEH & FFH. The register FEH is used to control bus (I
the registers. The register FFH is used to control register pages which are enable to receive data
6.5.3.Memory access is managed by:
FEH: Data port (Both Read/Write)
FAH~F8H: Address port (Both Read/Write)
F0H~F2H: Some Control bits are spread around F0H~F2H
Features:
A. Display function register set.
The display group can be classified into five separate section, namely, main display SVGA, OSD, PIP, and Hard
course display
B. Capture register set
The capture consists of two separate components. the main picture and PIP (Picture In Picture) block the
MP accepts analog signal through analog front end (AFE), and is processed through a TV decoder.
The TV decoder is equipped with a monitor decoder that can identify the area of picture containing motion so that
a good mix between the temporal and spatial (2D-Filiter) can be determined
the PIP block accepts a digital signal and provides a preferred format like the main picture block.
C.OSD.(On Screen Display):
An OSD block consisted of a pixel bitmap of OSD.4 bits per pixel. there are total of 16 colors for the
OSD display. there is 16*29 bits lock up table for DPTV3D each 4-bits OSD index corresponds to a 29 bits color
attribute, including 24 bits for the RGB true color data, 1 bit for blink function which enables/disables color blinking
the blinking frequency is controlled by a register another 4 bits are defined as a blend factor which can decide
16-transparancy degrees of the current OSD color with the background OSD
D. Display CRTC
DPTV display mode can be categorized by the following parameters:
D-1.Reflash rate
D-2.Number of pixels per scan line
D-3.Number of scan line per frame
D-4.Interlaced or progressive display mode
D-5.Tv tube horizontal frequency
C)or parallel that access
