Chroma 2238 User Manual

Operation
2-5
HDMI Parameters
 VIDEO PORT: It selects the output signal terminal for the timing.
 PIXEL RATE: It sets the output timing pixel rate.
 INTERLACE MODE: It set the interlace mode for the timing.
 COLOR SPACE: It selects YCbCr or RGB signal.
 COLOR DEPTH: It sets the color depth.
 PIXEL MODE: It specifies the YCbCr color signal encoding method when outputting the
YCbCr signal.
 HPD Enable: It sets whether enable the Hot Plug Detect function. When this item is
enabled and DTV is connected to VPG, it can output signal again if Hot Plug function is
enabled by VPG. If Auto Relink HDCP function needs to be enabled, this item also needs
to be enabled.
 HDMI AV MUTE: It selects if sending General Control Packet to DTV and commending
DTV to execute AV Mute when the VPG pattern is changed. If this parameter is enabled,
it will send the General Control Packet to give Set AV Mute command when the VPG
pattern is changed. Please note that when the HDCP function is enabled, the system will
give Clear AV Mute command before encrypting. It is because the HDMI Receiver
cannot decrypt Clear AV Mute command when the data is encrypted.
 HDCP Enable: It specifies if executing the HDCP function.
 HDCP Version: It specifies if running the HDCP version.
 3D TYPE: It sets the 3D type for output timing.
 HDR Enable: It specifies if executing the HDR function.
 HDR EOTF: It specifies the HDR format for execution.
 HDMI Scan Mode: It sets the “Scan mode” of Auxiliary Video information InfoFrame
control flag for output. This control flag is to inform the DTV what Scan Mode should be
used for showing the current video format.
 YC To RGB: It specifies if converting the color differential signal to output as RGB signal.
It simulates the DVD Player that decompresses the MPEG to output image data in RGB
mode.
 HDMI INFOGROUP: It selects the InfoFrame Group.
 HDMI Aspect Ratio: It sets the “Aspect Ratio” of Auxiliary Video information InfoFrame
control flag for output. This control flag is to inform the DTV what Aspect Ratio should be
used for showing the current video format.
 PIXEL REPET: It specifies the number of times for repeated data output.
 IT CONTENT: *TBD.
 HEX DATA: It sets the SMART I/O output signal.
DisplayPort Parameters
 VIDEO PORT: It selects the timing output signal terminal.
 PIXEL RATE: It sets the output timing pixel rate.
 INTERLACE MODE: It sets the timing to interlace mode.
 COLOR SPACE: It selects YCbCr or RGB signal.
 COLOR DEPTH: It selects the color depth.
 PIXEL MODE: It specifies the YCbCr color signal encoding method when outputting the
YCbCr signal.
 HDCP Enable: It specifies if executing the HDCP function.
 YC To RGB: It specifies if converting the color differential signal to output as RGB signal.
It simulates the DVD Player that decompresses the MPEG to output image data in RGB
mode.
 TRAINING MODE: It has Auto, Manual and Fast three modes for setting.
Auto Training: It uses the DPCD at Sink to perform Link Training (CR and EQ) and
output video.
Manual Training: It uses the user set Main Link and Bit Rate to perform Link Training
(CR and EQ) and output video. (The block values shown at the bottom of VPG window
