NV8500 Review

You may safely skip this section if you are familiar with the NV8500 routers.

The NV8500 family of routers comprises 4 routers:

• NV8144 — 8RU, 144×144 video matrix

• NV8140 — 8RU, 144×288 video matrix

• NV8280 — 16RU, 288×576 video matrix

• NV8576 — 32RU, 576×1152 video matrix

• Stand-alone NV8576-Plus — 32RU, 576×576 video matrix

• Expanded NV8576-Plus — Two 32RU frames, interconnected, 1152×1152 video matrix

The routers in the NV8500 family switch both video (SD, HD, 3Gig), and audio (AES sync and async). The routers support two classes of input and output cards:

1Standard

(The NV8140 does not support AES async at this time.)

2Hybrid

There are disembedder cards (that extract audio from video input).

There are embedder cards (that insert audio into video output).

There are MADI MADI input. MADI output cards have 16 video outputs and two MADI outputs. For the NV8576-Plus, there are expansion output cards that have 8 video outputs and one MADI outputs.

If any hybrid I/O cards are present, the router is considered a hybrid router. All its control cards and all its crosspoint cards must be hybrid cards. Otherwise, you can consider the router a standard router and all its control cards and crosspoint cards can be standard cards.

You can have a combination of the card types in your router. Standard input cards do not disembed audio; standard output cards do not re-embed audio. With the hybrid cards, the

routers can disembed audio, recombine the audio, and re-embed the recombined audio at output.

With DHP (dynamic hybrid pathfinding), the routers can route standard input through an internal pool of hybrid disembedder cards and embedder cards after which the audio from the standard input can be recombined and re-embedded on output. The point of DHP is that it allows you to populate the router with many relatively inexpensive standard I/O cards and a few hybrid cards and still have the benefits of hybrid routing (the ability to breakaway audio entirely within the router).

I/O Cards

Each router has a certain number of input card slots and a certain number of output card slots:

Router Input Slots Output Slots Nominal Video Matrix Size

NV8144 16 8 144×144

NV8140 8 16 144×288

NV8280 32 32 288×576

NV8576 64 64 576×1152

NV8576-Plus (stand-alone)

NV8576-Plus (expanded)

128 128 576×576

128 128 1152×1152

You may populate the slots with any type of input or output card your system requires.

Input cards are coupled with input backplane connector modules (or backplanes, for brevity). Output cards are coupled with output backplanes. Backplanes typically have coax (DIN 1.0/2.3) connectors or fiber optic (SFP) connectors. (Balanced AES modules use WECO quick-release connectors.):

DHP

Reference Manual

For routers other than the NV8140, Input backplane modules each have 9 connectors. Output backplane modules each have 18 connectors. Expansion output backplane modules (only for the NV8576-Plus) have 9 connectors and two 28-pin expansion ports.

For the NV8140, input backplanes for the NV8140 have 18 connectors.

Standard Cards

Standard input cards use all 9 connectors of the backplane modules. Standard output cards use all 18 connectors of the backplane modules.

Disembedder and Embedder Cards

For routers other than the NV8140, hybrid disembedder (input) cards use 8 of the 9 connectors. The 9th connector is not used. Hybrid embedder (output) cards use 16 of the 18 connectors. The 9th and 18th connectors are not used.

For the NV8140, hybrid disembedder (input) cards use 16 of their 18 connectors. The 9th and 18th connectors are not used.

Hybrid expansion embedder (output) cards use 8 of the 9 connectors.

There are no video ports or audio ports associated with the unused connectors.

MADI Cards

(MADI cards are also known as 3Gig/TDM cards.)

For routers other than the NV8140, hybrid MADI input cards use the first 8 connectors for video input and use the 9th connector for MADI input (up to 64 channels). Hybrid MADI output cards use connectors 1–8 and 10–17 for video output and use the 9th and 18th connectors for MADI output (56 or 64 channels each).

These MADI input cards have 64 audio ports. The remaining 80 ports of the card’s port space are unused.

For the NV8140, hybrid MADI input cards use connectors 1–8 and 10–17 for video input and use the 9th and 18th connectors for MADI input (up to 64 channels each).

These MADI input cards have 128 audio ports. The remaining 160 ports of the card’s port space are unused.

Hybrid MADI output cards use connectors 1–8 and 10–17 for video output and use the 9th and 18th connectors for MADI output (56 or 64 channels each).

Hybrid expansion MADI output cards use the first 8 connectors for video output and use the 9th connector for MADI output (56 or 64 channels).

MADI output cards have 128 audio ports. The remaining 160 ports of the card’s port space are unused.

Expansion Cabling for the NV8576-Plus

The expanded NV8576-Plus router comprises two interconnected router frames. The frames use expansion cards and expansion backplane modules. Expansion output backplanes have 9 connectors and two 28-pin expansion connectors. Cables connect the 2 router frames on the expansion connectors.

This scenario combines audio from 3 separate standard inputs and routes the video from one of the inputs with the combined audio on a standard output.

A disembedder port is required for each standard input port from which audio is to be extracted. An embedder port is required for the output that is to receive the recombined audio.

Further, an additional standard output port is required for each standard input port from which audio is to be extracted. An additional standard input port is also required for the output that is to receive the recombined audio.

The DHP service routes the signals through a pool of available hybrid cards internally. External cabling is required for every DHP path.

DHP Summary

Expansion output cards provide 9 outputs. Expansion output backplanes have 9 connectors and two 28-pin expansion connectors. Expansion filler cards provide no outputs, but support the expansion connections. Cables connect the 2 router frames on the expansion connectors.

DHP Summary

DHP (dynamic hybrid pathfinding) allows the NV8500 router to perform hybrid routing with relatively few hybrid cards. With DHP, the router passes standard inputs through an internal pool of hybrid disembedder cards and embedder cards after which the audio from the standard inputs can be recombined and re-embedded on output.

The point of DHP is that it allows you to populate the router with many relatively inexpensive standard I/O cards and a few hybrid cards and still have the benefits of hybrid routing (that is, to allow audio from standard inputs to be disembedded and re-embedded for standard outputs, all within the router).

DHP is a service that resides in the NV9000. The NV9000 control software treats the DHP service as if it were a hybrid router.

The DHP service then communicates with the router directly. All takes to a hybrid router go through the DHP service, transparently. All status from the router also goes through the DHP service.

DHP is licensed software (EC9540) that ships with the NV9000. The purchase of the license allows you to activate the DHP service in the NV9000. See Activation

Reference Manual

This is only one of a few dozen DHP scenarios. Other scenarios involve MADI inputs and outputs and AES inputs and outputs. See Examples

on page 24 for a discussion of DHP scenarios.

Preliminary DHP Analysis

In the analysis of your system, you should determine the number of inputs and outputs of each type:

Fig. 1-2: DHP Links

This evaluation includes the number of standard inputs and standard outputs, the number of hybrid inputs and outputs, and the number of AES inputs and outputs.

If your router is to perform DHP, you will also need the size of the DHP pool (or DHP “core”), i.e, the number of DHP links required by your router. This number might be difficult to determine. Keep in mind that the DHP links are dedicated disembedders and re-embedders and are not to be considered inputs and outputs. There are several factors to consider.

These are two of the factors:

1 The number of DHP paths that can be in use simultaneously.

2 The number of ports required for each path.

As stated earlier, and illustrated in Figure 1-1, a certain number of hybrid ports and a certain number of additional standard ports are required for each DHP path.

Potentially, 16 sources could each provide a single audio channel to an output. This would be considered an extreme and unusual case. If all 16 audio channels come from a single source, DHP is not used for that route. Thus, the minimum number of sources for DHP is 2 and the maximum is 16. The number of destinations for DHP is always 1.

You need to determine the average number of ports among all the DHP paths in use simultaneously. The average is, of course, somewhere between 2 and 16, probably very close to 2.

Thus, letting ‘A’ be the average number of sources, and ‘N’ be the number of simultaneous DHP paths,

Disembedder ports = A × N

Embedder ports = N

Additional standard input ports = N

Additional standard output ports = A × N

Note that DHP is used for disembedding and re-embedding audio. Therefore the hybrid cards that constitute the DHP core must be one of these:

[There are no fiber-optic hybrid cards at this time.]

Note: ports belonging to the DHP core cannot be used as routable inputs or outputs. Panel operators cannot route to them or from them directly.

Other DHP Considerations

Tielines

The NV8500 router that DHP is servicing might involve some tielines. You must identify the inputs and outputs of all tielines in a DHP configuration (initialization) file.

Force Embedder Off

The DHP configuration allows you to specify, for some inputs, that when they are routed to embedder outputs, the embedder is forced off (i.e, the embedder is bypassed). In such a case, the audio from the input is kept intact and passed through the output without change. This option is controlled by “EO” commands in DHP’s port configuration files.

It might be a point of confusion that, in MRC, there is just the opposite function: some inputs in the router are configured to force any embedding output to use its embedder, rather then let the router follow switching rules to determine the embedder state.

If your router uses DHP, it is imperative that you do not ever use the “force embedder ON” function in MRC.

ASI Signals

You must identify ASI inputs and ASI outputs in a DHP initialization file.

on page 16 for detail.

DHP is licensed software (EC9540) that ships with the NV9000. The purchase of the license allows you to activate the DHP service in the NV9000.

Follow these steps to activate the DHP service:

1 Obtain the NV9000 Control System CD from Miranda (GVD). This CD contains one or more

activation programs depending on which licenses you have purchased.

2 Copy the DHP activation file (presently SV1062-01.exe) from the CD to a USB drive.

3 Connect a keyboard, mouse, and monitor to the NV9000 frame.

4 Login to the NV9000. The default username is

ware

5 Insert the USB drive into a free USB slot of the NV9000.

6 When the USB drive window appears, double-click the DHP activation file. The activation

program takes no more than a second to finish.

7 Remove the USB drive from the NV9000.

 It might be convenient to activate all the services you have purchased at this time, if you

have purchased more than one. Just copy all your service activation programs to the USB drive and run each one individually on the NV9000.

 If you have an older version of the NV9000 software that does not include DHP, you will

need to obtain an updated version of the NV9000 software.

Repeat the activation process for each NV9000 that is to use DHP.

Configuration

As a service, DHP interprets take commands from the NV9000 and calculates routes that require disembedded and re-embedded audio, and relays appropriate commands to the router. DHP manages a pool of DHP ports that we call the DHP core. DHP also determines whether the route requires use of the DHP core. A case where it does not require the core is a take from a standard input to a standard output.

There are several steps in configuring DHP. These involve MRC, NV9000-SE Utilities (and your NV9000 configuration) and DHP configuration files.

The order in which you perform the configuration steps is not critical as long as you perform all the configuration tasks and have valid DHP configuration files installed before you restart your NV9000 with DHP active.

There is no feedback that can tell you whether DHP is active and running properly, except that DHP will not work if you have, for example, an improper DHP configuration file.

If you are using the NV9000 Web Suite to monitor DHP, and DHP is not operating, the DHP pages will “freeze” and display stale data. The web suite has no failure report.

another router (or possibly of the same router). A multi-hop tieline is one that involves connections among more than two routers.

Warnings

If you are adding DHP to an existing router, save your existing configuration before doing so. If you ever decide to stop using DHP, your router will need a non-DHP configuration to operate.

Do not restart your NV9000 without correct DHP configuration files. DHP might fail to start if it detects errors in its configuration files.

Assumptions made here: your NV9000 is configured and is communicating with the router that is to use DHP. This document does not address NV9000 configuration apart from the requirements for DHP.

Summary

This is a summary of the DHP configuration steps. Details follow.

1 Following your DHP analysis, populate the router with cards belonging to the DHP core.

Make notes about what you have done.

2 In MRC, define or redefine router partitions for the router.

3 In MRC, specify or re-specify the card types for all slots of the router.

4In MRC, ensure that no router input has its “force embedder on” attribute set true.

5 In NV9000-SE Utilities

a Make the NV9000 communicate with DHP (instead of the router)

b Make DHP communicate with the router’s control card(s).

6 In NotePad or a similar tool, write the DHP configuration files. Verify that they are correct and

save them in the folder

C:\nvision of the NV9000 system controller(s).

7 In NV9000-SE Utilities

a Ensure that a level set exists that includes all audio levels in use.

b Explicitly define all audio levels for standard inputs and outputs that can be switched

using DHP. [For standard I/O that will never be switched by DHP, this is not necessary.]

8 In NV9000-SE Utilities, if your router has MADI ports

a Add 40,000 to any and all MADI port numbers. (DHP requires this.)

b Add 40,000 to the audio matrix size.

9 In NV9000-SE Utilities, clear the DHP portion of the router’s crosspoint matrix.

10 Remove any previously defined sources and destinations from the DHP core portion of the

NV9000 configuration.

11 Finally, write the new configuration to the NV9000 and restart the NV9000. Then set the DHP

service to “automatic” and start the DHP service.

Configuration Process

[1] DHP Core

In your analysis of the DHP requirements of your router, you will have determined the number and type of hybrid cards to include in the DHP core.

If you are adding DHP to an existing router, place the disembedder (input) cards and embedder (output) cards that form the DHP core in the router. Also place the cards’ matching backplane connector modules. The cards in the DHP core do not have to be contiguous.

If you are starting with a new unconfigured router, it is probable that the cards belonging to your DHP core have been installed at the factory.

In either case, make sure that the cards and backplane modules are installed properly and make careful written notes about which slots you have used for the DHP core. The port numbers for the cards in those slots are critical to the configuration process.

[2]

Router Levels

DHP requires that your router have exactly one ‘Digital Video’ partition and one ‘Synchronous Audio’ partition. Partitions of other types are acceptable, such as a monitor partition. Use the ‘Router Levels’ page in MRC to define the partitions. This example is typical for an NV8280:

Fig. 2-1: Router Partitions for an NV8280 Using DHP

Reference Manual

[3] NV9000-SE Configuration

If you are adding DHP to a router, you will have to change your NV9000-SE Utilities settings to conform to what is discussed here.

DHP stands between the NV9000 control process and the router. The control process communicates with DHP as if it were the router. Therefore, in NV9000-SE Utilities, you must specify the IP address of the router as 127.0.0.1 (which is, in a sense, the address of DHP). If you are creating a new router definition, you will see a page similar to this:

DHP

Fig. 2-2: Router Details (NV8280 Shown)

Note: if your router has MADI cards, add 40,000 to the audio level size (i.e., to the ‘Input End’ field and the ‘Output End’ field).

(This IP address is called a “loopback address.”)

Note that NV9000-SE Utilities will give you a warning message, because, under normal circumstances, 127.0.0.1 is an unusable address:

You can ignore this message, because the use of DHP is an exceptional circumstance.

DHP Service

Configuration Process

Then, in the ‘Control Points’ table (under the ‘Views’ navigation pane), change the description field for the DHP proxy of the router: This is a sample control point table (for an NV8280):

Changing the description is not actually necessary, but very helpful.

If you are modifying an existing router definition, it is here that you would change its IP address to 127.0.0.1.

Then, update the parameters fields in the ‘Router Controls’ table:

Define the parameters field as “E”, comma, and the IP address of the router control card. Doing that lets the DHP service know the IP address of the router control card with which it is to communicate.

(If you are modifying an existing router definition, the values you enter in the parameters field here are what were in the parameters field of the control points table. These IP addresses will have been initially defined in MRC.)

When there are two control cards, one primary and one secondary, only one of those control cards is actively running. The other control card is in stand-by mode.

Similarly, when there are two control cards, the NV9000 will launch two DHP services at startup. One of the DHP services is active and the other is stand-by (running, but idle).

At this stage, the ‘Control Points’ table is not quite finished

— you must specify the DHP ports.
