INTRODUCTION Congratulations on your purchase of the 3GSDI Audio De-Embedder. Your complete satisfaction is very important to us. GefenPRO In the realm of video distribution, certain features are invaluable in a commercial or broadcast environment. Accommodations such as a build-in power supply and flat black rack-mount enclosures set GefenPRO apart from our traditional products. Complex distribution units allow for professional DVI, 3GSDI, and HDMI signals to be routed and converted easily and seamlessly, while being backed up by a renowned and dependable technical support team. Gefen invites you to explore the GefenPRO product line and hopes that you find the solution that fits your needs. The GefenPRO 3GSDI Audio De-Embedder The GefenPRO 3GSDI Audio De-Embedder extracts audio from 3GSDI, Single-Link HDSDI, EDSDI, and SDI video signals.Up to four AES/EBU digital audio streams can be de-embedded and routed to any of the four audio outputs. Selection and routing of each audio group or pair can be configured via RS-232. How It Works Connect an SDI source to the SDI In connector. Connect the SDI Loop Out connector to an SDI audio/video device to monitor the original unmodified signal. Connect the Output connector to an SDI acceptor (such as video broadcast equipment). Connect up to four AES/EBU digital audio reproduction devices (such as a DAT recorder or pre-amp) to the Audio Out connectors. Connect the RS-232 cable from the Audio De-Embedder to a PC or automation system to control which audio group or pair will be de-embedded from the video signal. Connect the AC power cord to the 3GSDI Audio De-Embedder and to an available electrical outlet. Once the unit is powered, RS-232 commands can be used to select the audio group and pair to be de-embedded from the video signal.

OPERATING THE 3GSDI AUDIO DE-EMBEDDER Signal Flow The 3GSDI Audio De-Embedder core has three main elements to provide switching of audio groups and audio channels: • 4x2 Switcher (input) The first element allows any two of the four SDI audio input groups (Group 1 - Group 4) to be routed to the source groups (S1 - S2). For example, Group 1 can be routed to S2 and Group 3 can be routed to S1. Only one SDI audio input group can be routed to a source group at a time. Group 1 Group 2 SDI In Group 3 Group 4 • 8x16 Matrix with Delay Once the selected SDI audio input groups have been routed to the source groups, any of the four source audio channels (S1.1 ... S2.4) can be routed once or multiple times to any of the output audio channels (O1.1 ... O1.4, O2.1 ... O2.4) or to any AES audio channel (A.1 ... A.8).
Page 14
OPERATING THE 3GSDI AUDIO DE-EMBEDDER Note in the diagram, on the previous page, that souce audio channels S1.1, S1.3, S2.1, S2.2, and S2.3 are routed to multiple output audio channels and AES audio channels. Audio delay (from 0 to 170 ms) can be applied, if desired, to each output audio channel and/or each AES audio channel before being sent to the output groups or Audio Out BNC connectors. • 2x4 Switcher (output) The third and final stage combines the individual output channels into two output groups (O1 and O2). The output groups are then delivered to the specified SDI audio output group (Group 1 ... Group 4). In addition, any individual AES audio channels are combined as audio pairs (A.1 + A.2, A.3 + A.4, etc) and delivered to the Audio Out connectors: A.1 + A.2 are sent to Audio Out 1, A.3 + A.4 are sent to Audio Out 2, and so on. Group 1 Group 2 SDI Out Group 3 Group 4 Audio Out 1 Audio Out 2 Audio Out 3...
OPERATING THE 3GSDI AUDIO DE-EMBEDDER Controlling and Routing Audio Data The following example illustrates how the RS-232 commands are used to route audio channels. Before getting started, see page 10 on configuring RS-232. The first step is to route which SDI audio input groups are to be routed to the source groups. Use the #sdi_in_grp_sw command to assign the specified SDI audio group to the desired source group. In this example, we will route SDI audio input group 1 (g1) to source group S2 and SDI audio input group 3 (g3) to source group S1: #sdi_in_grp_sw g1 s2 Error! G1 has been already assigned to S1 Here, we tried to route Group 1 to S2. However, by default, Group 1 is already routed to S1. We must first “un-route” Group 1 by routing an unused SDI audio input group to S1. Looking at the illustration, below, we can see that we can use either Group 3 or...
Page 16
OPERATING THE 3GSDI AUDIO DE-EMBEDDER Since Group 3 has been routed to S1, we can now route Group 1 to S2: #sdi_in_grp_sw g1 s2 IN GROUP G1 IS SWITCHED TO S2 GROUP Group 1 Group 2 SDI In Group 3 Group 4 Use the #ch_sw command to select which source audio channels (S1.1 ... S1.4, S2.1 ... S2.4) are routed to the output audio channels (O1.1 ... O1.4, O2.1 ... O2.4, and A.1 ... A.8). S1.1 O1.1 S1.2 O1.2 S1.3 O1.3 S1.4 O1.4 S2.1 O2.1 S2.2 O2.2 S2.3 O2.3...

In this example, S2.1 is routed to both A.1 and A.7: #ch_sw s2.1 a.1 S2.1 IS SWITCHED INTO a.1 OF SDI TRANSMITTER #ch_sw s2.1 a.7...
OPERATING THE 3GSDI AUDIO DE-EMBEDDER Un-routed Source and AES Channels Note, that in our example, that we did not route source channels S1.3 and S2.2. According to the block diagram on page 8, each source channel is routed to an associated output channel (S1.1 > O1.1, S1.2 > O1.2, etc). This is the default setting. Although we did not specify S1.1 to be routed to O1.1, the default routing state still applies (indicated by the dashed-lines). The same holds true for the default routing state for S1.4 > O1.4, S2.2 > O2.2, and S2.4 > O2.4. In addition, AES audio channels (A.1 ... A.8) will receive source channels S1.1 through S2.4, respectively. It is important to understand that since S1.3 was never routed in our example and because S1.1 was routed to O1.3, the default routing for S1.3 (S1.3 > O1.3 and S1.3 > A.3) cannot take place. S1.1 O1.1 S1.2 O1.2 S1.3 O1.3 S1.4 O1.4 S2.1 O2.1 S2.2 O2.2 S2.3 O2.3 S2.4 O2.4 A.1 A.2 A.3 (S1.4) A.4 (S2.1) A.5...
Page 19
OPERATING THE 3GSDI AUDIO DE-EMBEDDER The final step is to route the output channels to an SDI audio output group. In our example, we will route O1 to Group 4 and O2 to Group 1. #sdi_out_grp_sw o2 g1 Error! G1 has been already assigned to O1 As with the SDI audio input groups, O1 and O2 are routed to Group 1 and Group 2, respectively, by default. Therefore, O2 cannot be directly routed to Group 1. O2 must first be re-routed to another Group, even if it is temporary. Group 1 Group 2 SDI Out Group 3 Group 4 Audio Out 1 However, since part of our example involves routing O1 to Group 4, we can perform this task first by using the following command: #sdi_out_grp_sw o1 g4 OUT GROUP O1 IS SWITCHED TO G4 GROUP Group 1 Group 2 SDI Out...
OPERATING THE 3GSDI AUDIO DE-EMBEDDER Now that O1 has been routed to Group 4, we can now route O2 to Group 1: #sdi_out_grp_sw o2 g1 OUT GROUP O2 IS SWITCHED TO G1 GROUP Group 1 Group 2 SDI Out Group 3 Group 4 Audio Out 1 Audio Out 2 Audio Out 3 Audio Out 4 The numbers next to each arrow indicate the audio channel number. See the Audio Mapping table below for details. Since AES audio was routed in step 2 (page 12), we don’t have to worry about routing the audio at this stage. As mentioned earlier, any individual AES audio channels are combined as audio pairs (A.1 + A.2, A.3 + A.4, etc) and delivered to the Audio Out connectors: A.1 + A.2 are sent to Audio Out 1, A.3 + A.4 are sent to Audio Out 2, and so on. Audio Mapping The 3GSDI Audio De-Embedder can process a maximum of eight audio channels. The audio-mapping table is listed below.
