Model CC-101 & CC-101-PRO

1.0 General

Thank you for purchasing Hall Research’s CC-101 or CC-101-PRO

Closed Caption Decoder and Text Video Overlay Unit.

These units can capture the closed captioning text (CC1 through CC4),

information and then overlay it on the video output. They can also display

any user defined text anywhere on the video. On the CC-101-PRO units,

the closed captioning text can also be streamed out the serial port and

captured on another device.

The closed captioning overlay can be turned on or off from the front

panel. Furthermore, the unit can decode CC1 through CC4.

The unit is equipped with a serial port, through which the unit can display

user defined text anywhere on the screen. The unit also has EEPROM

(internal non-volatile flash memory) in which the user store up to 10

strings of data and automatically display them either every time the unit is

turned on or the playback can be activated via the front panel.

Free Windows™ software is available that allows the user to define and

store text in the unit’s memory for playback. This powerful software

allows timers so the text can stay for predefined time on the screen. You

can also configure the unit to end and freeze the last displayed text on the

screen or to loop the playback from the beginning ad infinitum. Also,

during the playback, you can turn on Closed Caption decoding for long

periods of time. This makes the unit to be useable as a digital signage

playback device where either constantly or periodically you can display

stored messages.

The CC-101 has both S-Video and Composite Video inputs and outputs.

There is a front panel switch that you can use to select the input that you

are going to use. If you select the CV input then you must use the CV

output and if you use the S-Video input, then you should use the S-video

output. Do not use the unit to convert from one standard to another.

The CC-101-Pro also has progressive outputs of either component video

(Y Pb Pr 480p/576p) or VGA (RGBHV 640x480/800x600). There is

switch on the front panel to set the progressive output mode as either

component video or VGA. The progressive output resolutions are based

on the input standard (NTSC/PAL).

3.0 Installation

. Included Cables

The CC-101 comes with a 6 ft Male/Female DB9 Serial Cable. The –

PRO also includes HD15-to-3 RCA cable for component video output.

All other cables are to be supplied by the user.

. Inputs & Outputs

The CC-101 has 2 video inputs: S-Video and Composite Video. The unit

has 2 video outputs: S-Video, Composite Video. –PRO unit also has a

choice of, VGA or Component Video.

On CC-101 use the same output as the input (S-Video or Composite

Video), there may be an image on both outputs, but the one not

corresponding to the input, will have color or image artifacts. The -PRO

output will display either the S-Video input or the Composite video input.

Model CC-101 & CC-101-PRO

. Connecting the CC-101

Connect your video source (S-Video or Composite Video) to the CC-101

and select the source by pressing the “Input select” button on the front

panel. If the selected input does not have valid video, then the

corresponding LED on the front panel will be blinking.

On the –PRO unit connect the video output to your display device using

either a VGA cable or the supplied HD15 to Component cable. If you

have a –PRO unit, the front panel PRO OUTPUT will be lit.

Connect the included power supply to the CC-101-PRO and apply power

(do not substitute power supplies, inputs over 5.5 VDC cause damage).

For programming the unit’s internal memory with your own text or for

streaming ASCII data to the unit, Connect the supplied DB9 RS-232

Serial cable to your PC and the CC-101 or CC-101-PRO.

. Rack Mounting the CC-101

The CC-101 has threaded holes on the bottom that allows 3 of them to be

installed on a Hall Research 1U rack mount shelf (Model RMS-1U-1A)

Closed Caption & Text on Video Overlay

4.0 Operation

. Closed Captioning

The CC-101-PRO has the ability to display 4 different Close Captioning

data channels. The CC data channels that can be displayed are CC1, CC2,

CC3, and CC4.

The CC-101-PRO can cycle between CC1 and a user-defined CC

Alternate, which can be defined as CC2, CC3, or CC4. Defining the CC

Alt selection is done via the RS-232 Serial interface, but it is set as CC2 at

the factory. See the Overlay Mode Parameter Commands section for

specifics.

Selecting the CC data channels is accomplished by pressing the

“CLOSED CAPTION” select button on the front panel. The button will

cycle between: CC1 ÎCC Alt ÎCC off. The respective LED’s will be

turned on or off.

Model CC-101 & CC-101-PRO

. Text Overlay

Text Overlay is the ability to superimpose user-generated text over the

output video. Text Overlay and CC are mutually exclusive; i.e. at any

given time, you can only display CC or text overlay but not both. Text

Overlay is generated via RS-232 Serial port (in live mode) using an

application such as HyperTerminal, or played-back from internal memory.

Note on RS-232 port availability on your PC

Some PCs and notebooks do not have a

serial port. To program the sender you may

need a USB to RS-232 Serial converter.

These are available from Hall Research

(Model USB-RS232-1).

Text overlay requires a video input; this means that if you have no video

connected, you cannot get a video output.

The unit can display a variety of text styles on the screen as shown below:

. CC Stream out (CC-101-PRO Only)

Press the “CC” and the “Pro Output” selection buttons simultaneously to

enable/disable the Closed Caption streaming out through the RS232 serial

port.

When the Closed Caption stream out is enabled, the CC green LED will

blink for 3 seconds. And when the Closed Caption stream out is disabled,

the CC red LED will blink for 3 seconds.

To have the unit default to streaming the CC out on power up, you must

use the RS232 port with the available GUI software to turn on the feature.

Closed Caption & Text on Video Overlay

5.0 Storing and playing back

messages from internal memory

The CC-101 units will playback data from its internal user programmable

memory. While the unit is in playback mode, the CC mode LEDs will be

blinking. To stop playback, hit the CC mode selection button.

. GUI (Graphical User Interface by Hall Research)

You can download a Windows® GUI from the CC-101(-PRO) product’s

webpage on www.hallresearch.com. There are multiple versions of the

program available depending on the revision of firmware in the device.

The newer revisions programs are not 100% compatible with older

firmware devices.

This software will allow you to upload up to 10 different strings to the

CC-101 or CC-101-PRO for text overlay. Each of these 10 strings may be

up to 200 bytes in length. A wait time of 0 seconds to 65,535 seconds

may be added to the end of each of these strings.

After these strings have been uploaded to the CC-101(-PRO), there are 4

different ways to tell the CC-101(-PRO) how to show these stored strings.

1. Specify, in the GUI, to show these stored strings every time the

unit is turned on.

2. Press the “Input” and the “CC” selection buttons simultaneously

for 3 seconds. Hitting the closed caption “CC” mode button will

terminate the playback mode. (Note that there is a slight delay

after pressing the buttons before the playback starts). Both the

red and green led’s will blink to indicate that a playback is

occurring.

3. Specify, in the GUI, to show these stored strings immediately

after the upload is complete, via the “Show strings on upload”

checkbox.

4. Send a hex command to display these stored strings on power-

up. Hex commands are listed in table 2.

These 10 strings can be composed of ASCII characters, Hexadecimal

characters, and special TOC (text overlay commands)

Model CC-101 & CC-101-PRO

. . Selecting the Com Port

The Programming Software will detect your available COM ports. Just

select the COM port you will use to connect the CC-101(-PRO) to your

PC.

. . How to insert Text Overlay Commands

Select the command from the “Command to Insert” drop down menu

Depending on the command selected, a parameter may be needed. If a

parameter is needed you will need to specify a value in the Command

Parameter text box.

After you have entered a valid parameter, the Insert Command Button

will show up and be available. Click on this button and the command will

be inserted into the selected string at the current position.

. . Inserting Hex Bytes

Enter a 1 byte hexadecimal value into the Hexadecimal text box then click

the Insert Hex Byte button and your hex byte will be inserted into the

selected string at the current position.
