Key Features and Application examples for the FS2

Introduction

The new FS2 from AJA is a wide ranging work!ow king in a small 1RU form factor, making it suitable for use in myriad environments; from Production to Post, OB to Broadcast.

Such power and !exibility in a dual channel universal HD/SD audio/video frame synchronizer and format converter makes a thorough reading of the indispensable FS2 user manual a must, for those who wish to truly utilize it’s power and full work!ow range.

FS2 Application highlights

The FS2 can be used in a wide variety of video and audio signal conversion, adaptation, timing, and processing applications.

Highlights include:

• Up/down/cross conversion between various SD and HD formats, including 1080p50/60.

• General purpose video frame synchronization.

• Analog-to-Digital and Digital-to-Analog audio/video conversion.

• Mux or Demux Dual Stream HD (two separate HD signals) from one 3G SDI signal.

• Convert 3G/HD/SD video over !ber to or from SDI (BNC).

• Use the built-in video processing ampli"ers to adjust and/or color-correct video streams.

• Synchronize the timing of key and !ll signals by putting both through the parallel FS2 video channels and adjusting their timing independently. Then key them using one of the two FS2 keyers or an

external keyer.

• Use the HDMI input and a DVI-to-HDMI cable to scan-convert popular computer video formats to SD or HD, including full proc-amp functionality and aspect ratio adjustment (future "rmware release).

• HD sidebar keying including using both SD video and SD sidebar graphics (analog or digital), upconverting both, and combining—all within the FS2.

• Dolby E encoding and decoding with full channel mapping (future option).

Key Features and Application examples for the FS26/2011

See Fig. 2

Fig. 2



Dual Stream 3G Input/Output

"Dual Stream 3G SDI" means two separate and distinct HD video signals are muxed together into one 3G SDI signal. (By de"nition, a "Dual Stream 3G SDI" is a "Level B' 3G SDI.) The FS2 supports this mode, both at the inputs and the outputs. Also, Dual Stream 3G automatic operation (signal detection) is possible if proper Format ID is present, or you can set up Dual Stream 3G manual operation if Format ID is not available.

Dual Stream 3G Video Inputs

The FS2 inputs support Dual Stream 3G SDI Inputs by applying the Dual Stream 3G video to SDI 1 In and making the second video stream appear in the input crosspoint matrix as SDI 2.

In this case, the SDI 2 input connector is unused.

1. Connect a (muxed) Dual Stream 3G SDI signal to SDI 1 In.

2. Press the System button, select 4 SDI1 3G Format Detect, and adjust to Auto Detect or Muxed Video.

3. Select 5 SDI2 Input Protect, and adjust to SDI1 Ch2 (Muxed Video).

Now both HD signals from a Dual Stream 3G SDI input are available as SDI1 or SDI 2, and either input can be selected for use in Processor 1 or Processor 2. The Fiber 1 input can also be used in this way.

6/2011


Dual Stream 3G Video Outputs

Two separate 1.5 Gb HD video signals, one from Processor 1 and one from Processor 2, can be combined at the FS2 output into one (muxed) Dual Stream 3G SDI signal. The Dual Stream 3G output can be selected at the four SDI outputs: SDI 1, SDI 2, Fiber 1, or Fiber 2.

1. Press the Output button.

2. Select one of these menus to specify which output(s) will produce Muxed 3G video:

SDI 1 Out: Select 1.1 SDI1 Video Output, and adjust to Proc1+Proc2.SDI 2 Out: Select 1.2 SDI2 Video Output, and adjust to Proc1+Proc2.Fiber 1 Out: Select 2.1 Fiber1 Video Output, and adjust to Proc1+Proc2.Fiber 2 Out: Select 2.2 Fiber2 Video Output, and adjust to Proc1+Proc2.

Dual Stream 3G Inputs to Separate SDI Outputs

This variation shows you how to input (muxed) Dual Stream 3G and demux it to produce separate SDI outputs.

The setup is:

• Apply (muxed) Dual Stream 3G video (Level B—two 1080i59 images) to SDI 1 In.


• Video 1 Input set to SDI 1.• Output Format set to 1080i59.94.• Video Output Mode set to Normal.


1. Press the System button.

2. Select 4 SDI1 3G Format Detect, and adjust to Auto Detect or Muxed Video.(Note that Auto Detect uses the SMPTE 352 embedded Format ID data stream to automatically detect Muxed 3G video.)

3. Select 5 SDI2 Input Protect, and adjust to SDI1 Ch2 (Muxed Video).

4. Press the Video 1 button, select 2 Output Format, and adjust to 1080i59.94.

5. Select the Output button, select 1.1 SDI1 Video Out, and adjust to Processor 1.

6. Press the Video 1 button, select 1 Video 1 In, and adjust as follows:a. Adjust to SDI1 (display bottom line shows SDI1-1). The SDI 1 Output is now 1080i59.94 stream 1 of the input video.b. Adjust to SDI2 (display bottom line shows SDI1-2). The SDI 1 Output is now 1080i59.94 stream 2 of the

input video.

As you can see, using the ADJUST knob, you can select which stream of the (muxed) Dual Stream 3G input video you want to see at the SDI 1 Output.

The two demuxed video streams are also available at the other outputs—SDI 2, Fiber 1, and Fiber 2 if you switch those outputs to show the desired input stream.

INPUT/OUTPUT OF “DUAL LINK” 1080P50/60(Dual 1.5Gb HD-SDI Links)

“Dual Link” means a 1080p50/60 signal carried on two separate 1.5 Gb HD-SDI links. Per SMPTE 372, the two links are named “Link A” and “Link B.” The FS2 supports this format on both Input and Output.

DUAL LINK INPUT:

The FS2 supports Dual Link 1080p50/60 Inputs by using both SDI IN1 and SDI IN2, or Fiber IN1 and Fiber IN2. The FS2 combines the two inputs into a 1080p50/60 signal before sending it to the Input Crosspoint Matrix.

1. Connect a Dual Link 1080p50/60 signal to Inputs SDI 1 and SDI 2 as shown2. Select “SDI Dual Link” in Video Menu1 (Either Video Processor can use the Dual Link Input)

Note that the same function is supported by Fiber Input 1 and 2

6/2011


INPUT/OUTPUT OF “DUAL LINK” 1080P50/60(Dual 1.5Gb HD-SDI Links)

DUAL LINK OUTPUT:

The FS2 supports Dual Link 1080p50/60 Outputs by separating a 3Gb 1080p50/60 signal from the Output Crosspoint Matrix into two 1.5Gb outputs which are then sent SDI OUT 1 and SDI OUT 2, or FIBER OUT 1 and FIBER OUT 2.

1. Select “1.5 Gb Dual Link” in Output menu 9.1 (or 10.1 for Fiber Output)

Video Conversion Characteristics

The FS2 can convert almost any video input format to nearly any output format, as long as the frame rates are of the same family.

The three video format families supported by the FS2 are:

• 59.94/29.97/23.98• 50/25 • 60/30/24

Speci"c exceptions to the format conversion capability are listed below. When attempting these conversions, the FS2 intelligently causes a Video Format alarm:

• 525i59.94 -> 1080p (and pSF) 23.98• 1080i59.94 -> 1080p (and pSF) F23.98• 720p59.94 -> 1080p (and pSF) 23.98• 720p29.97 -> 1080p (and pSF) 23.98• 1080p29.97 -> 1080p (and pSF) 23.98• 1080pSF29.97 -> 1080p (and pSF) 23.98• 625i60 -> 1080p (and pSF) 23.98• 1080i60 -> 1080p (and pSF) 23.98• 720p60 -> 1080p (and pSF) 23.98• 720p30 -> 1080p (and pSF) 23.98• 1080p30 -> 1080p (and pSF) 23.98

Video Format Alarms

Whenever incompatible I/O formats are detected, an alarm is triggered and these results are produced by the FS2:

1. Lights the relevant alarm LED on the front panel (FMT ERROR, 1 or 2).2. Displays an alarm in the browser user interface.3. In!uences selection of the "rst-displayed status screen.4. Generates an SNMP trap (if con"gured).5. Triggers a GPI Output (if con"gured).
