Configuration

The 8964DEC can be configured locally using onboard switches or
remotely using the 8900NET network interface GUI or a networked control
panel.

Refer to the following sections for configuration instructions:

•Configuration Summary (page 13)

• Local Onboard Module Configuration (page 20)

•Remote Control and Monitoring (page 26)

•Control Panel Configuration (page 51)

Operation of these control types is explained in detail in their respective
sections of this manual.

Configuration

Configuration Summary

This section provides a summary of all parameters that can be configured
on the 8964DEC module. The video processing configuration is described
by what line types will be affected by the adjustments or choices made. Use
this section in conjunction with the specific configuration method instruc­tions for each configuration type. Table 5 on page 18 provides a summary
in table format of all parameters and their ranges, default values, and
remote, local, and control panel function names and locations for setting
each value.

Video Processing Controls

The 8964DEC provides video processing controls for the decoding process
for all four channels independently. How the video data is processed
depends on what line the video is on. Some processing affects all lines,
other processing affects just the active picture lines, programmable VBI
lines or the fixed VBI lines.

Line Categories

The line categories used in the configuration of the video signal for the
8964DEC are defined as follows:

• F_Active Lines – the portion of the active video that is fixed and always
treated by the module as carrying active video (not programmable).

• P_Active Lines – lines in the active video that can be configured by the
user to carry either active video or be reserved for carrying user data.

8964DEC/-FS Instruction Manual 13

Configuration

• CVBI – the lines in the vertical interval that can be configured by the
user.

•FVBI – the line in the vertical blanking interval that are fixed and are not
configurable.

The line numbers for each category above are defined in Table 3 for both
525 and 625 line rates on the 8964DEC module.

Programmable VBI and Active Picture Lines – Composite Input

Programmable lines in the composite input vertical blanking interval
include the configurable VBI lines (CVBI). Programmable active picture
lines (P_Active) are the lines reserved for carrying data (Data Lines) (refer
to Table 4 on page 14). Both of these line pair types can be configured for
the following:

•Decode Mode – select from Notch Decode or Pass Through (blank U
and V). (Global control – all line pairs are affected in the same manner.)

Note

•Chroma Kill – removes all chroma on VBI and P_Active lines reserved

Video Timing and Freeze Controls

With a standard 8964DEC module with no Frame Sync enabled the fol­lowing Line Sync timing adjustment is available:

•Horizontal Timing – adjusts the horizontal delay on the channel output

in pixels. This will add an additional delay of up to one line.

With an 8964DEC-FS module (8964DEC with Frame Sync enabled, see

Module Option Upgrade on page 51), the following Frame Sync timing

adjustments can be made:

•Horizontal Timing – identical to the line sync timing above.

•Vertical Timing – adjusts vertical delay in line increments.

Also available with the 8964DEC-FS are the following freeze controls:

•None – when signal is lost, no automatic freeze occurs and no manual

freeze is activated.

•AutoBlue – when AutoBlue is enabled on a channel, the output will

automatically freeze to a blue screen when the input signal is lost on
that channel.

Configuration

•AutoFreeze – when AutoFreeze is enabled on a channel, the output will

automatically freeze on the last valid field when the input signal is lost
on that channel.

• Field 1 – manually freezes the output signal on field 1 of the last frame.

• Field 2 – manually freezes the output signal on field 2 of the last frame.

• Frame – manually freezes the output signal on the last frame.

A field freeze provides less resolution and no motion artifacts in the output.
In frame mode, the resolution is higher since both fields are present, but the
presentation of the two fields can cause motion artifacts.

Picture Enhancer Controls

The Picture Enhancer feature is standard on the 8964DEC and 8964DEC-FS
modules. This feature allows separate picture enhancement control on each
channel output. Picture enhancement affects all lines of video.

Use the following controls for picture enhancement:

•Disable – the Picture Enhancer process can be turned off by selecting

Disable.

• Picture enhancement can be enabled by selecting one of three settings,

Low, Medium, or High. Amount of adjustment will depend on picture
type and noise level.

Configuration

Local Onboard Module Configuration

The 8964DEC module can be configured locally using the rotary and
paddle switches. Several LEDs interact with the switches to indicate status
of the configuration process.

Configuration Switches and Controls

Each of the four decoder channels is adjusted separately. Selection of each
channel is done with the paddle switch while in Channel Select Mode as
explained below. Refer to Figure 5 on page 21 for the following descrip­tions. Use the onboard configuration components as follows:

•SW1 Function (rotary) switch – this switch accesses a desired function
for configuration (see Table 7 on page 24). The switch addresses three
banks of functions; each bank has 16 possible positions (0 through 9 and
A through F). Not all positions are used.

The next bank of functions is accessed each time the Function switch
makes a complete revolution past zero (or back through F): While in
Bank 1, a complete revolution past zero accesses Bank 2; while in
Bank 2, a complete revolution past zero accesses Bank 3. The yellow
2ND LED indicates which bank is currently being accessed.

Note The Function switch should be kept in position 0 in any bank (parked) when

not in use to avoid any inadvertent change in configuration. Position 0 in each
bank is inactive.

•2ND (second Function) yellow LED – when off, indicates that the rotary
switch is addressing the first bank of functions. When on, indicates that
the rotary switch is addressing the second bank of functions. When
flashing, indicates that rotary switch is addressing the third bank of
functions.

•SW4 (paddle) switch – actuates or selects the desired setting or channel
selection for the selected function when the switch is held momentarily
in either the up or down position. Switch between Parameter and
Channel Select Mode with pushbutton SW4.

•CSM (Channel Select Mode) yellow LED – when on, paddle switch is in
Channel Select Mode. Use the paddle switch to select channel 1, 2, 3, or

4. When off, paddle switch is in Parameter mode.

• CM1 and CM0 LEDs – indicate what channel is active for adjustment.
Refer to Table 6 on page 21.

•SW2 (pushbutton) switch – press to toggle assignment of paddle switch
SW2 between Parameter mode (CSM LED off) and Channel Select
Mode (CSM LED on).

• CONF (configuring) yellow LED – when on, indicates the module is ini­tializing or processing configuration information.
