The various serial digital interface standards all use coaxial cables with BNC connecters, with a
nominal impedance of 75 ohms. The data of image, sound and various digital information (Line Counter,
CRC) can carry hundreds meter far using coaxial cable. Transfer is serial communication, but the final
processed image data is processed the parallel RGB or YCbCr such as the [Table 2].

2.4.4 J3, J8 BNC Connecter
BNC(Bayonet Neil-Concelman) connecter is a miniature quick connect/disconnect RF
connecter used for coaxial cable. It features three part of cable, at the center of the signal
lines and coax internal signal that surround outer conductor (shield), and insulation. BNC
connecters are made to match the characteristic impedance of cable at either 50 ohms or 75
ohms. The 75 ohm types can sometimes be recognized by the reduced or absent dielectric in
the mating ends.

2.5 Ancillary Data
USB3-FRM14 board can show Vertical Ancillary Data (VANC).
Ancillary Data(commonly abbreviated as ANC Data), in the context of television system,
refers to a means which by non-video information(such as audio, other forms of essence, and
metadata). It may be embedded within the SDI(Serial Digital Interface), is standardized by
SMPTE291M(Ancillary Data Packet and Space Formatting).
ANC data are divided into two types as [Figure 2-10], depending on where they are located.
Ancillary packets located in the horizontal blanking area, are known as Horizontal Ancillary
Data or HANC, HANC is commonly used for higher-bandwidth, mainly is embedded audio. In
case of HD can be embedded 16 channels audio. Ancillary packets located in the vertical
blanking area, are known as Vertical Ancillary Data or VANC. VANC is commonly used for
lower-bandwidth. Closed caption data and VPID(Video payload identifier) are generally stored
as VANC.
[Figure 2-11. HANC and VANC Area]
Page 14
USB3-FRM14 Users Manual (Rev 1.1)
-14- http://www.daqsystem.com
All ANC packets must start with a specific start sequence, for component interfaces(the only
kind of Srial Digital Interface is widespread use today), the start sequence is 0x00 0x3FF 0x3FF.
This sequence is otherwise illegal in the serial digital interface. These words follow the start
sequence in the header. The first word after the start sequence is the DID(Data Identifier),
followed by either a SDID(Secondary Data Indetifier or a DBN(Data Block Number), followed
by a DC(Data Counter). After the DC word are 0 ~ 255 UDW(User Data Words), followed by a
CS(Check Sum).
Depending on the configuration of the ANC Packet is divided into Type1 and Type2.

(2) DID --- Data Identification word indicates the type of ancillary data that the packet corresponds
to. Data identifiers range from 0 to 255, with 0 being reserved.
A Serial Data Interface is a 10-but format, the DID word is enclosed as follows:
Bit 0 ~ 7 : raw DID value
Bit 8 : even parity from bit 0 to bit7
Bit 9 : Not Bit8
Thus, a DID of 0x61(011000001) would be enclosed as 0x161(01011000001), where as a
DID of 0x63(01100011) would be encoded as 0x263(1001100011).
If the DID is equal to 128(0x80)or greater, then the packet is a Type 1. And the DID is
less than to 128, it is a Type 2 Packet.

The SDID is only if the DID is less than 128(80 hex), is normally an 8-bit value. It is
encoded in the same fashion as the DID.
Bit 0 ~ 7 : b7 (MSB) through b0 (LSB) identification bit word (00h ~ FFh)
Bit 8 : even parity from Bit 0 to Bit7, Bit 9 : Not Bit8
(4) DBN --- The Data Block Number is only valid if the DID is 127(80 hex) or greater. It is used to
identify multiple packets of the same type within a field. The DBN is an 8-bit value,
encoded in the same fashion as the SDID.

DLL file (USB_FRM14.DLL) must be located in the same directory with the execution file or
Windows system folder. Another method is to add the directory of API DLL file to PATH
environmental variable.

5. Test
For Vertical Ancillary (VANC) Data test, we are used with USB3-DIO01 and USB3-SDI01. USB3-
DIO01 is USB3 interface Base Board with having the multi-function to process the data from/to the
daughter board's signal. And, USB3-SDI01 is a simulator board for VANC data signal, it is changed SDI
signal from the data of USB3-DIO01 and transmits the USB3-FRM14 board. Make sure that the VANC
data is received correctly by connecting the USB3-DIO01 board USB3-SDI01 board as in [Figure 5-1].
HD-SDI camera is used the two cameras that support the 1080p (1920x1080 @ 30fps).

The first and second VANC data is only displayed in [Figure 5-10]. If necessary, user can be used
4 VANC data packet by user defined. ANC data packet is 512 bytes including the part of Header and
other packet information and user data’s (UDW) 255bytes. The second VNC packet starts address
200h in [Figure 5-10], this means the packet size is 512bytes.
More explain concretely, Vertical Ancillary Data starts at the beginning of the “00” “ff” “ff”. “01”
“01” “0a” of DID SDID DC value shows the red line of the right side, and the last value CS of
VANC can be seen in the red circle. In addition, the data values are same (see the blue line).
(Notice) 1. Interlace mode does not currently support.
2. BNC Channel 0(J8 connector) has a priority, must be always used in
connection from the beginning.
3. Each channel can not connect to the other resolution. The resolution of
channel 1, it must be the same as the resolution of channel 0.
