ABOUT DVI & HDCP

CenterStage CS-1 and CS-2 Video Processors suppor t the most common flavor of digital source and display standards, DVI. With DVI, or the Digital Visual Interface, video remains digital from the graphic source (PC, DVD, HTPC, etc. ), through the CenterStage, and to the display (television, monitor, projector, plasma, etc. ). The CenterStage DVI input will accept the following input resolutions:

640x480 60Hz 1024x768 60Hz 720x576 60Hz 1280x960 60Hz 800x600 60Hz 1280x1024 60Hz

High-bandwidth Digital Content Protection (HDCP) is a content protection scheme used with DVI to prevent unauthorized copying and redistribution of digitally perfect content. Original content via computer display cards or game consoles, and video from standard definition DVD players will not likely be content protected. High-definition set-top boxes are expected to be HDCP enabled to protect high-definition movies and pay-per-view programming. DVI with HDCP is standard on CenterStage CS-2, and optional on CenterStage CS-1, so both are fully compatible with any HDTV installation.

When using an HDCP encrypted DVI input source, analog output is disabled.

For more information on upgrading your CenterStage CS-1 to enable HDCP, contact FOCUS Enhancements’Technical Support (for more information, see page 7 of this manual. )

APPENDIX A

RS-232 pin configuration

CenterStage requires a standard AT style cable for connection to the RS-232 port. The pin conf iguration of the port is as follows:

RX Data Pin 3 TX Data Pin 2 GND Pin 5

No handshaking provided or required.

RS-232 Control Protocol

NOTE: This section is intended for those with a strong technical knowledge. This information is not needed for day to day understanding of CenterStage operation. If you have any questions about control, consult your dealer or distributor or contact Focus Enhancements, Inc. directly.

It is possible for CenterStage to be controlled by RS-232 control codes for compatibility with several Home Theater control systems. The interface should be able to control almost all aspects of the unit. The structure provides for setting features of the unit, as well as interrogating the box for it's current settings.

Protocol:

The protocol has the following 6 byte command structure for the interface. Attention Byte: 0xEE Number of Bytes to follow: 0x04 Command Byte: 0x00 through 0xDF Data Byte 0: MS hex digit, 0-9, A-F, ASCII Value Data Byte 1: LS hex digit, 0-9, A-F, ASCII Value Checksum Byte The 7 bit sum of the preceding 5 bytes.

The Attention Byte is a unique code. The Number of Bytes to follow includes the Command Byte, Data Bytes and Checksum Byte. The Command Byte would range from 0x00-0xDF, so that they never overlap the Attention Byte range. The Data Bytes express an eight bit value from 0 through 255 if viewed as an unsigned number, or -128 through 127 if it specifies a relative adjustment or a signed number. Each Data Byte is the ACSII representation of the hex digit. The Checksum Byte would be the sum of the five preceding bytes, with the MSB set to “0”

Command Bytes:

Command Bytes are documented in the spreadsheet RS-232Control Codes. XLS, and at the end of this document.

There are specif ic Command Bytes for Writing to the CenterStage registers, and a different set of Command Bytes for interrogating (Reading) the CenterStage for it's current settings.

Read Commands:

When a READ Command is written to CenterStage, the Protocol above is followed, with the Data Bytes being set to “0”. The CenterStage will respond with the same 6 byte command str ucture, but the Data Bytes will be filled in with the current setting. The client must wait for either a valid response or an error response (NAK) before proceeding with additional communications.

Absolute Write Commands:

When an Absolute Write Command is written to CenterStage and the command is recognized as valid, the Data Bytes will be used to change the setting of the selected function. The client MUST wait for either an ACK or NAK before proceeding with additional communications.

PAGE 30

CenterStage

Page 31

Relative Write Commands:

When a Relative Write Command is written to CenterStage and the command is recognized as valid, the Data Bytes will be used to adjust the setting of the selected function. The Data Bytes will be treated as a signed byte. For example, an “FF” (-1), will lessen the setting by one, and a “05” will increase the setting by five. The client MUST wait for either an ACK or NAK before proceeding with additional communications.

BAD Commands:

When an invalid command is received by CenterStage, it responds with an ASCII NAK (0x15).

GOOD Commands:

When a valid command is received by CenterStage, it responds with an ASCII ACK (0x06).

Handshaking:

As described above, all commands to the CenterStage will be responded to by either an ACK, NAK, or a Read_Response. It is suggested that the Client monitor the replies by waiting for an Attention Byte after a Read Command, an ACK, or a NAK. The Client should disregard all other received bytes until it receives one of the specific bytes mentioned above.

Limits:

It should be expected that many registers would have limits on the range of the Data Byte. If a command is received where the Data Byte value falls out of the range of acceptable values, the CenterStage will be set at the Limit, and the Data Byte of the response from CenterStage will reflect that limit. The response will not reflect the erroneous value.

Command Set:

The Command values given below are for a Relative Write Command. The values for an Absolute Write Command are the values listed below + 0x30. The values for a Read Command are the values listed below + 0x60.

#define WRITE_POWER 0x50 #define WRITE_INPUT_ASPECT 0x51 #define WRITE_VID_PROC 0x52 #define WRITE_SELECT_INPUT 0x53 #define WRITE_OUTPUT_ASPECT 0x54 #define WRITE_RESET 0x55 #define WRITE_FRONT_PANEL 0x56 #define WRITE_OUTPUT_RES 0x57 #define WRITE_SHARPNESS 0x60 #define WRITE_CONTRAST 0x61 #define WRITE_BRIGHTNESS 0x62 #define WRITE_V_SZ_MODE_INPUT 0x63 #define WRITE_V_POS_INPUT 0x64 #define WRITE_H_SZ_INPUT 0x65 #define WRITE_H_POS_INPUT 0x66 #define WRITE_V_SZ_OUTPUT 0x67 #define WRITE_V_POS_OUTPUT 0x68 #define WRITE_H_SZ_OUTPUT 0x69 #define WRITE_H_POS_OUTPUT 0x6A #define WRITE_COLOR_ADJUST 0x6B #define WRITE_TINT_ADJUST 0x6C #define WRITE_OP_FMT 0x6D #define WRITE_COLOR_ MODE 0x6E

APPENDIX B Input Aspect Ratio to Output Aspect Ratio Primer

WHAT INPUT ASPECT RATIO SETTINGS DO

(4:3 Mode) If you are playing a DVD, and the DVD player is in “Normal TV” mode, a circle will appear as a circle on a standard TV. In this case, you should have the Input Aspect Ratio set to 4:3. This preserves a circle as a circle, and does not stretch the image horizontally. You should use 4:3 input mode if the DVD player is in “Normal TV” mode, even if the movie is a wide screen movie.

(16:9 Mode) If you have the DVD player set to “Wide TV” mode or “Anamorphic mode”, a circle will appear as a tall oval on a standard TV. In this case, you should set the CenterStage to have the Input Aspect Ratio set to 16:9. This mode stretches the image horizontally, and changes the tall oval back into a circle on the display device!

(4:3LB Mode) If you have the CenterStage in 16:9 Output Mode with content that is standard 4:3 (black bars on the left and right when displayed on a standard TV), and you don't like the black bars on the left and right of the displayed image, then you should set the CenterStage Input Aspect Ratio to 4:3LB mode. This will expand the image vertically and horizontally to eliminate the black bars on the left and right, as well as expand the image and crop the top and bottom, filling the screen. This 4:3LB Input Mode only makes sense when you are in 16:9 Output Mode.

(16:9 LB Mode) If you have the CenterStage in 16:9 Output Mode with content such as a 2. 35:1 DVD (black bars on the top and bottom even when displayed on a 16:9 display), and you don't like the black bars on the top and bottom of the displayed image, then you should set the CenterStage Input Aspect Ratio to 16:9LB mode. This will expand the image cropping the far right and left, and eliminating the black bars on the top and bottom, filling the screen.

WHAT OUTPUT ASPECT RATIO ACTUALLY DOES

Display devices today have either a 4:3 aspect ratio or a 16:9 aspect ratio. A typical LCD or DLP projector is made from a 4:3 display element, and will want to display a 4:3 image at its maximum resolution. CRT projectors can be adjusted to be either 4:3 or 16:9 output. There are also 16:9 native CRT direct view monitors and some rear view projection displays that are inherently 16:9 as well.

If you had a native 4:3 display device (let's say an XGA projector, 1024x768), you could project it on a 4:3 screen, and it would display its full resolution on that screen, (See Example A). If you took the same 4:3 display device and projected it on a 16:9 screen, you would lose a portion of the display resolution off the top and bottom of the screen (making this area black). You would only be viewing a portion of that XGA resolution (1024x576 to be exact). The remaining 192 lines (768-576=192 lines) would need to display black data so that you are not projecting an image on your wall above and below the screen, (See Example B). This portion of the original resolution of the display is lost! A wide screen movie would look great, but a 4:3 image would need to be centered in the 16:9 screen to look right. It will have lost a lot of its resolution, since now only a small central box of the original 1024x768 display resolution can be used to display the image. This box is now 768x576. See Example C.

Example A Example B Example C Example D

If your display device is native 16:9, and you are projecting on a 16:9 screen, the CenterStage should be set for 16:9 output. A wide screen movie should fill the screen assuming that the movie is also 16:9 or 1. 78:1. If the movie is wider, for example 2. 35:1, you will see some black area on the top and bottom of the screen due to the image being wider and shorter than 16:9. If you are viewing a 4:3 image, you will see black bars on the right and left sides of the image, because a 4:3 image is not wide enough to fill the screen. See Example D.
