Introduction In This Chapter This chapter includes the following sections: • A Word of Thanks • Overview • Functional Block Diagram • Features • Documentation Terms A Word of Thanks Congratulations on choosing the openGear 9321 HD/SD Audio Embedder. The 9321 is part of a full line of modular conversion gear for broadcast TV environments. The Cobalt Digital openGear line includes video decoders and encoders, audio embeders and de-embeders, distribution amplifiers, format converters, and much more.
All card configuration is done with a simple front panel menu. There is a four character text display to view and control parameters, and a toggle switch and two buttons to navigate the menu. All settings available on the front panel can also be accessed through Dashboard remote control software provided the openGear frame being used has an 8310-N network card installed. The card has persistent storage of all settings.
There is also a video proc module to allow any necessary corrections to the inbound video signal. It has separate controls for Luma gain (Y channel), Saturation (C channel gain), Lift (Y channel offset), and Phase adjustment (C channel). Supported Audio and Video Formats Input and Output Video The 9321 supports a wide range of video formats for embedding. The output video rate is always precisely the same as the input video rate. Video delay through the device is less than one microsecond. Table 1.
Analog Audio The 9321 supports 8 channels differential analog audio. The analog audio is encoded in such a way as to make +24 dBu (analog) equivalent to 0 dBFS (digital). Analog audio conversion can be disabled to reduce power consumption. Discrete AES Audio Input The 9321 can accept 16 channels (8 pairs) of discrete AES audio on 75 ohm BNC connections. The AES must have a nominal rate of approximately 48 kHz.
Installation and Setup In This Chapter This chapter includes the following sections: • Static Discharge • Unpacking • Rear Module Installation (Optional) • Board Installation • BNC Connections • Menu Structure • Factory Defaults Static Discharge Whenever handling the card and other related equipment, please observe all static discharge precautions as described in the following note: Static discharge can cause serious damage to sensitive semiconductor devices.
Rear Module Installation (Optional) If you are installing the card in a 8310-C-BNC or 8310-BNC frame (one with a 100 BNC rear module installed across the entire back plane), skip this section. If you are installing the card into a slot with no rear module, you should have ordered and received a 8310-RM-10 Rear Module with your card. You will need to install it in your 8310 frame before you can connect cables. Use the following steps to install the 8310-RM-10 in an 8310 openGear frame: 1.
Board Installation Use the following steps to install the card in the openGear 8310 frame: 1. Warning Refer to the User Manual of the openGear 8310 frame to ensure that the frame is properly installed according to instructions. Heat and power distribution requirements within a frame may dictate specific slot placement of cards. Cards with many heat-producing components should be arranged to avoid areas of excess heat build-up, particularly in frames using convection cooling. 2.
Card Control and Status Card Status The card indicates the status of the input signal with the four blue LEDs labled with the different supported formats (1080, 720, 625, 525). When the card has locked to a particular input format, that LED will be illuminated. When the card has not locked to a particular video format, the card will search all possible formats, and the lights will cycle rapidly. Menu Navigation The card can be configured from a menu system built in to the front card edge.

Proc Gain This is Luma (Y channel) gain, expressed as a percentage. It ranges from 0.0% to 200.0% in 0.1% steps. Proc Lift This is Luma (Y channel) offset, expressed as an actual video value ranging from -1024 to 1024. If set to 0 no change is made. If set to 1024 absolute black (value 004) becomes absolute white (value 3FB). If set to –1024, absolute white becomes absolute black. Proc Saturation This is Chroma (C channel) gain, expressed as a percentage. It ranges from 0.0% to 200.0% in 0.1% steps.
Display Brightness This parameter allows you to set the standard output brightness of the menu display. It is a percentage of maximum brightness. Save Settings In this parameter, move the toggle switch up to save the settings to the card persistent storage. Load Settings In this parameter, move the toggle switch up to load the saved settings and make them active.
Remote Control In This Chapter This section provides a detailed explanation on using remote control functions with your card. DashBoard Control System Software The DashBoard Control System enables you to monitor and control openGearTM frames and controller cards from a computer. The DashBoard software and manual can be downloaded from the Cobalt Digital Inc. website. Using the Menus You must first install the DashBoard Control System software on your computer.
