M-GWIPSDI-6 IP to SDI gateway

Robust IP to SDI conversion

The M-GWIPSDI-6 IP gateway de-encapsulates SDI from uncompressed 10GbE IP networks and is the best choice for integrating IP into an SDI environment. It's ideal for any ST 2022 system and for ST 2110 studio environments when the video and audio are processed separately. It comes with an extensive list of features which bring multiple benefits to the broadcaster and which make it easy to get and keep IP systems working.

Supporting the SMPTE ST 2022-6 and 2022-7 protocols, as well as video within ST 2110, the M-GWIPSDI-6 converts to six HD/SD or three 3Gb/s SDI output connections, with flexible assignment of the converted flows from either of the two input 10GbE IP network interfaces.

Alternatively the second 10GbE network interface can be configured for SMPTE ST 2022-7 redundant input streaming or the protect equivalent for ST 2110.

Being six channel means it saves rack space while making each channel cost-effective, and also allows the user to switch between different inputs and send to multiple outputs. This flexible internal routing removes the need for additional distribution amplifiers and routing switches. Video glitches on input source switching are avoided thanks to the clean instant switching.

IP inputs are individually selectable between ST 2022 and ST 2110, allowing you to input both ST 2022 and ST 2110 at the same time if required.

When used with ST 2022, all video, audio and ancillary data is transferred from the IP input to the SDI output. When used with ST 2110, the video from the IP input is taken to the SDI output which will be output without embedded audio. ST 2110-30 audio packets are not processed within this app.

There is a choice of fibre modules for the fibre SFP+ 10GbE IP network interfaces: either 850nm multi-mode for up to 300m or 1310nm single-mode for up to 10km.

The M-GWIPSDI-6 is tolerant of any input packet distribution, with the variable input buffer compensating for any timing irregularities. Any traffic shaping option from ST 2110-21 can be used, or packets can come from a device which does not meet the shaping requirement of ST 2110-21.

Other features include full VLAN support with no restrictions and unicast and multicast transmission support.

It's a software app

The future-proof M-GWIPSDI-6 is a software app that runs on the MARBLE-V1 media processor – purpose-built GPU/CPU hardware that fits in the Vision frames.

As a system becomes all IP, less gateways are required - and apps that are bought with the hardware can be replaced with different apps as needs change, helping you make the most of your budget.

More about MARBLE-V1

Featuring a powerful CPU/GPU processor, the MARBLE-V1 media processor hardware has six bi-directional SDI connections and four 10GbE SFP+ network interface ports (as well as eight bi-directional discrete AES stereo channels for future products).

The software app installed determines the functionality.

Instant clean switching between flows

There are six clean switches and any of the input flows can be routed to any SDI output. Any network can be routed to any input flow.

Choice of timing sources

SDI sources are synchronised to a common reference timing source for clean switching of input flows to the SDI outputs. The framestore synchroniser makes all the timing identical and so allows for each output to cleanly switch between any of the inputs, and enables the app to give a continuous clean output when the selected input is disrupted.

The M-GWIPSDI-6 supports PTP in addition to the Vision frame's two analogue references as a timing source, with user configurable options for timing source priority and redundancy. The chosen reference is the global reference source for all input flows and SDI outputs.

Reference redundancy offers peace of mind in case the main reference source is disrupted or needs to be taken down for maintenance, while cross-locking allows for mixed reference type and format installations if required.

There are five options for the reference selection, selectable via VisionWeb. (See the Specification for full details.) Should the timing source at the top of the list become missing or invalid, the card will move down the list until it finds a valid timing reference source.

The output timing can be fully adjusted with respect to the chosen reference using three time-based controls (0 - 42ms adjustable in 0.1ms steps, 0 - 100us adjustable in 1us steps and 0 - 1us adjustable in 5ns steps), with the selected timing alignment global to all output flows.

An additional ten frames of video delay (adjustable in one frame steps) allows compensation for any big system delays and can be configured individually for each SDI output.

Monitoring your signals

Features are provided to speed up system trouble shooting, particularly helpful with IP being more challenging to debug than SDI. Comprehensive SDI, IP and PTP monitoring information is available and can be used to generate SNMP traps.

The status indications available are video present and time present, video format, video black, video frozen, video error, Reference 1 and 2 present and time present, Reference 1 and 2 format, PTP master and backup clock present and time present and audio groups present. The video black and video frozen alert can be delayed by up to 120 seconds to prevent false alarming during brief video pauses.

PTP presence and statistics (network delay, delay variation, reference offset and sync period) are monitored.

The IP flow monitoring on the input flows includes network error, packet loss, duplicated packets, packet delay variation, Ethernet interface ignored packets and Ethernet interface ignored multicast.

13 built-in test patterns can also help with fault finding.

Flexible control

All control is done remotely, with a choice of remote control and monitoring options for the M-GWIPSDI-6 app running on the MARBLE-V1 media processor.

Hardware control options include an integrated control panel on the Vision 3 frame, the VisionPanel remote control panel and the SBB-4 smart button box.

Software control options include SNMP, our ASCII and JSON protocols and the VisionWeb web browser control. Try the M-GWIPSDI-6 VisionWeb demo...

16 presets can be assigned and recalled.

Save rack space

Fitting in the standard Vision frames (currently available in 3U size), MARBLE-V1 is a space-saving 96mm x 325mm card that sits in one frame slot – allowing up to ten media processors in 3U. The double slot VR06 frame rear module is used to access the inputs and outputs on the M-GWIPSDI-6 app.

MECHANICAL

‘Double slot’ Vision card 96mm x 303mm (96mm x 325mm including finger pull)

Weight: 355g

Power consumption: 25 Watts, plus 1 Watt for each SFP+ fitted to MARBLE-V1

INPUTS AND OUTPUTS

Input connections: Up to two fibre SFP+ 10GbE IP network interfaces. Choice of fibre modules: either 850nm multi-mode (for up to 300m) or 1310nm single-mode (for up to 10km)

Output connections: Six BNCs for SDI

Requires at least one SFP+ transceiver option, up to a maximum of two. Use one SFP+ to put all signals together and use two SFP+ to have main and protect or multicast and unicast on separate network interfaces

Inputs can be mixture of ST 2022 and ST 2110

Video, audio and data can be passed between ST 2022 and SDI

Video can be passed between ST 2110 and SDI, while audio and any other non-video data will be lost

FLOW INPUTS

Three 3Gb/s video over IP inputs or six HD or SD video over IP inputs

If the input is 3Gb/s then flows 1, 3 and 5 should be used, and flows 2, 4 and 6 (both input and output) should be disabled

Packet distribution is not important as variable input buffer will compensate for any timing irregularities. Any traffic shaping option from ST 2110-21 can be used, or packets can come from a device which does not meet the shaping requirement of ST 2110-21

A protect input for SMPTE ST 2022-7 seamless protection switching or the equivalent protect input in ST 2110-20 can come from either of the 10GbE IP network interfaces. This protects the stream from lost packets by creating two streams of the same data using different routing to the destination. Flow analyser handles the analysis and reconstruction of the protected stream. Any IP input can come from either of the 10GbE IP network interfaces and can either be multicast or unicast

VIDEO OUTPUTS

Three 3Gb/s SDI outputs or six HD or SD SDI outputs

270Mb/s or 1.5Gb/s or 3Gb/s serial compliant to SMPTE 259, SMPTE 292-1 and SMPTE 424/425-A

VIDEO DE-ENCAPSULATION

SDI is de-encapsulated from 10GbE IP networks

Any network can be routed to any input flow

ROUTING

There are six clean switches

Any of the input flows can be switched to any SDI output. The default setting is Flow 1 to SDI 1, Flow 2 to SDI 2, Flow 3 to SDI 3, Flow 4 to SDI 4, Flow 5 to SDI 5 and Flow 6 to SDI 6

VIDEO LOSS CONTROLS

The video loss/format mismatch controls allow the user to select what will happen to an SDI output in the event that the input is lost or the video format does not match the specified format. The user can specify to freeze the last good frame or show a black or blue screen or 100% colour bars (with or without an initial delay of three seconds). No output can also be selected. This is independently adjustable on each SDI output

TEST PATTERNS

The test pattern controls allow the user to override an input and force the SDI output to output a test pattern including Colour Bars, Blue, Black, EqCheck, PllCheck, Pluge, Checkfield, Grey Horizontal Steps, Grey Vertical Steps, Luma Horizontal Ramp, Luma Vertical Ramp, Cycle Colour or Checker Board, or to freeze the picture. This is independently adjustable on each SDI output

SYNCHRONISER AND TIMING ADJUSTMENTS

Video sources are synchronised to common reference timing source for clean switching of input flows to the SDI outputs

Choice of timing options:

• PTP (SMPTE 2059-2) master and backup, via 10GbE IP network interface
• Two tri-level syncs or analogue Black and Burst references (Reference 1 and Reference 2), connected via the Vision 3 frame

Chosen reference is the global reference source for all input flows and SDI outputs

There are five options for the reference selection, selectable via VisionWeb. The hierarchy runs from left to right – should the timing source at the top of the list become missing or invalid, the card will move down the list until it finds a valid timing reference source:

• PTP>Ref1>Ref2>Hold
• PTP>Ref1>Hold
• PTP>Ref2>Ref1>Hold
• PTP>Ref2>Hold
• PTP>Hold

(“PTP” means PTP Master>PTP Backup. “Hold” means it will hold the timing of the last good reference)

When using video reference, video inputs can be different formats but only inputs with the same frame rate as reference video will be locked to that reference. Input signals of same frame rate as reference will be locked together and locked to external reference. Inputs with a differing frame rate will be locked and maintain timing with no drift, but their sync point will be undefined (all same frame rate signals will, however, be locked to each other)

When using PTP reference, input sources of different format and/or frame rate will all be correctly locked to the PTP reference

When Auto relock enable is selected, the card will automatically relock when a lost reference is restored. Selecting Force lock (with Auto relock disabled) will force the synchroniser to relock after a reference is restored, and can be activated at a non-critical time to avoid video disturbance

Output timing can be fully adjusted with respect to the reference using three time-based controls: 0 - 42ms adjustable in 0.1ms steps, 0 - 100us adjustable in 1us steps and 0 - 1us adjustable in 5ns steps. Sub frame timing alignment to chosen reference is global to all outputs

An additional ten frames of video delay (adjustable in one frame steps) allows compensation for any big system delays. This delay can be configured individually for each SDI output

ANCILLARY DATA

All ancillary data from ST 2022 is passed from input to output. ST 2110 input is video only

LED INDICATION OF:

Power okay

PRESETS

The current app settings can be saved in one of 16 locations to be recalled as required

SIGNAL MONITORING

Comprehensive SDI, IP and PTP monitoring information is available and can be used to generate SNMP traps

Checks can be performed on the following video and audio parameters:

• Video present and time present
• Video format
• Video black
• Video frozen
• Video error
• Audio group 1 present
• Audio group 2 present
• Audio group 3 present
• Audio group 4 present

Black or frozen video will be indicated by an amber LED. This alert can be delayed by 1-120 seconds to prevent false warnings during brief video pauses

The following IP parameters are monitored for input flows:

• Network error
• Packet loss
• Duplicated packets
• Packet delay variation. Shown as the skew (difference in time of packet arrival) between the main and protected input, and also as the min and max nano second gap between the packets on each input

The Ethernet interfaces are monitored for:

• Count of packets ignored by the app (general network traffic non-media packets, which do not require processing by the app). Jumps in 100 step increments indicate network traffic flood
• Ignored multicast packets. LED indicates multicast traffic not requested by the app is present on the Ethernet Interface, indicating incorrectly configured IGMP at the network switch

References are monitored for:

• Reference 1 and 2 present and time present
• Reference 1 and 2 format
• PTP master and backup clock present and time present
• PTP statistics – network delay, delay variation, reference offset and sync period

REMOTE CONTROL

Software:

VisionWeb Control is available via the web server on the frame and allows control and monitoring using a standard web browser on a computer, tablet or phone

SNMP monitoring and control available as standard

Control using ASCII and JSON protocols

Hardware:

Control from integrated control panel on Vision 3 frame

Control from VisionPanel 3U remote panel

SBB-4 smart button box connects to the frame via Ethernet and provides four programmable LCD switches (which are configured for each order). The SBB-4 uses information from VisionWeb for settings. Uses Power over Ethernet so must be used with PoE enabled switch

 

Signal inputs and outputs are accessed by using an appropriate rear module.

The Vision rear modules slot on at the back of the frame and typically feature BNC, Micro BNC, D-Type and LC fibre connectors.
