M-CLEANIT

The perfect profanity delay

The M-CLEANIT profanity delay offers numerous (and unique) ways to deal with video and audio profanities to keep your content protected.

In a profanity delay system a live content stream is delayed to give the operator time to react and prevent the broadcast of unwanted or offensive video or audio material. The M-CLEANIT allows the live stream to be delayed by up 600 frames, which is 24 seconds in 1080i50, 20 seconds in 1080i59.94, 12 seconds in 720p50/1080p50 and ten seconds in 1080p59.94.

Equally suited to traditional broadcasting or social media webcasts, the M-CLEANIT is the ideal product to prevent expletives, obscene gestures, wardrobe malfunctions, bloopers, competitor mentions, coughing fits or technical problems from making it to air.

Use it with IP, SDI or both

The M-CLEANIT can be used with IP, with SDI or with both IP and SDI at the same time. Its support for multiple signal formats gives the easiest possible SDI to IP upgrade, while also making it perfect for mixed SDI and IP installations as well as fully IP or fully SDI environments.

It supports both SMPTE ST 2022 video over 10GbE IP networks, including ST 2022-7 redundant streaming. Full ST 2110 support will be coming soon.

The IP flows can be separated and protected across up to four bi-directional 10GbE SFP+ network interfaces. 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.

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

It's a software app

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

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.

Flexible video and audio cover

The M-CLEANIT offers you incredible flexibility to manage your content. All of the cleaning features are user configured and individually controlled – making it easy for operating procedures to be established for each production, tailored to the content.

The video and audio cover options are extensive. You can clean switch to two different video sources, jump ahead in time of the offensive content, blur the video, make the video black or blue, show colour bars, show a web page, mute individual audio channels or switch to another audio flow.

Flexible delays to suit different workflows

One of the M-CLEANIT's most useful features is the flexibility of its delays: the 'delay to event' and 'delay to restore' can either be the same length or different, which allows for further customisation of the workflow. Using the same 'delay to event' and 'delay to restore' requires the operator to hold the button for a bit longer after the profanity has finished. Setting a longer 'delay to restore' adds some safety delay to ensure all objectionable content is covered, and in this workflow the operator can release the button as soon as the profanity has cleared.

There are also override controls which act immediately – ideal for emergency situations where the profanity was missed.

Monitoring your content with confidence

The M-CLEANIT provides two outputs, one of which can be set to show the Monitor output which allows the user to monitor everything that is happening with confidence of the content.

This fixed multiviewer simultaneously shows the Live Source A video, Cleanit Out video, Delayed Source A video, Source B video and Source C video – as well as the Event pending and Event active tallies.

In addition, the Live Source A audio is monitored.

With this monitor output available as either SDI or IP, it allows – for example – an IP programme to be monitored using a legacy SDI viewing station.

IP gateway and translation functionality included

The M-CLEANIT's gateway functionality can be used to integrate SDI into an IP environment or IP into an SDI environment.

Its IP to IP translation functionality can be used for network address translation, protocol conversion (between any of the input formats and any of the output formats), unicast to multicast address conversion and the creation of media firewalls.

Traffic shaping

With the potential for networks and IP receivers to not be very tolerant to bursty traffic, the M-CLEANIT will ensure a nicely constructed IP output (with a choice of traffic shaping options), while its tolerant IP input is designed to be robust to bursty traffic.

Choice of timing sources

The M-CLEANIT includes a framestore synchroniser timed to an external Black and Burst or tri-level syncs analogue reference or PTP.

The chosen reference is the global reference source for all input and output flows.

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 up to ten 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.

Ten frames of flow input video delay and ten frames of flow output video delay (adjustable in one frames steps) are available in addition to the M-CLEANIT's main programme delay.

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 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.

Easy control - the SBB-4 smart button box

The recommended way to operate the M-CLEANIT is by using the SBB-4 smart button box.

The SBB-4 buttons are momentary when used with the M-CLEANIT, with a button press to initiate the ON action and a button release to trigger the OFF action – which results in very precise cleaning. The buttons execute their action after the user-defined delay times out. With the default for the SBB's four buttons being Mute A, Blur A, Switch to B and Switch to C, a customer can request any of the available actions to be assigned to a button.

The SBB-4 works in conjunction with VisionWeb, with – for example – VisionWeb providing the delay time variables and status information.

The SBB-4 connects to the Crystal Vision frame via Ethernet. It uses PoE (Power over Ethernet) for convenience and therefore needs to be connected to a PoE enabled switch.

Other control options

In addition to the SBB-4, other hardware control options include an integrated control panel on the Vision 3 frame and the VisionPanel remote control panel.

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

16 presets can be assigned and recalled.

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

INPUT AND OUTPUTS

Inputs can be IP and/or SDI

Outputs can be IP and/or SDI

Five BNCs for SDI and up to four 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)

IP inputs and outputs can be ST 2022 (NB. ST 2110 coming soon)

IP only, SDI to IP and IP to SDI applications require at least one SFP+ transceiver option, up to a maximum of four. Use one SFP+ to put all signals together, use two SFP+ to have main and protect or multicast and unicast on separate network interfaces and use three or four SFP+ to further separate flows

SDI only applications do not require any SFP+, unless using a web server for a web page cover source in which case one SFP+ will be required

SDI VIDEO INPUTS

(NB. Some or all of the inputs can be IP instead)

Up to three 3Gb/s or HD or SD SDI inputs

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

3Gb/s cable equalisation up to 100m using Belden 1694A. HD cable equalisation up to 140m with Belden 1694A or equivalent (approx. 100m with Belden 8281). SD cable equalisation >250m Belden 8281 or equivalent

IP FLOW INPUTS

(NB. Some or all of the inputs can be SDI instead)

Up to three 3Gb/s or HD or SD video over IP inputs

Packet distribution is not important as variable input buffer will compensate for any timing irregularities

A protect input for SMPTE ST 2022-7 seamless protection switching can come from any 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 any of the 10GbE IP network interfaces and can either be multicast or unicast

SDI VIDEO OUTPUTS

(NB. Some or all of the outputs can be IP instead)

Up to two 3Gb/s or 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

IP FLOW OUTPUTS

(NB. Some or all of the outputs can be SDI instead)

Up to two 3Gb/s or HD or SD video over IP outputs

Any of the 10GbE IP network interfaces can be used to provide a protected output for SMPTE ST 2022-7, which protects the stream from lost packets by creating two streams of the same data using different routing to the destination

Alternatively it is possible to have a unicast on some network interfaces and a multicast on others

VIDEO FORMATS SUPPORTED

The video formats supported are 625i, 525i, 720p50, 720p59.94, 720p60, 1080i50, 1080i59.94, 1080i60, 1080p23.98, 1080p24, 1080p25, 1080p29.97, 1080p30, 1080p50, 1080p59.94, 1080p60, 1080PsF23.98, 1080PsF24, 1080PsF25, 1080PsF29.97, 1080PsF30, 2048x1080p23.98*, 2048x1080p24*, 2048x1080p25*, 2048x1080p29.97*, 2048x1080p30*, 2048x1080PsF23.98*, 2048x1080PsF24*, 2048x1080PsF25*, 2048x1080PsF29.97*, 2048x1080PsF30* (*= YUV 4:2:2 10 bit)

Packet shaping and distribution (optional in ST 2022) is selectable per flow between TPNL and TPN (narrow linear or narrow gapped packet distribution). There is also a mode for burst packet distribution with a control for the burst rate limit. This is for connecting between Crystal Vision and other compatible devices that allow for a reduced transmission delay

SMPTE ST 2022-7 flow protection facilitates the dual stream output

VIDEO AND AUDIO COVER

To prevent profanities from being broadcast, it is possible to clean switch to two different video sources, jump ahead in time of the offensive content, blur the video, make the video black or blue, show colour bars, show a web page, mute individual audio channels or switch to another audio flow

SOURCES

Source A: Flow in 1, Flow in 2 or Flow in 3 can be selected as the Source A programme feed

Source B: Flow in 1, Flow in 2 or Flow in 3 can be selected as an alternate 'safe' feed to switch to during a cover event

Source C video: Flow in 1, Flow in 2, Flow in 3, Blurred A, Delayed A, Black, Blue, Colour bars or Web server can be clean switched to during a cover event. Web pages can be accessed remotely – with two DNS servers available – or can be stored internally on Vision 3 frame via FTP, with storage expandable via internal SATA SSD drive. Note: For only the Source C audio to be affected during a Switch to C event, select Delayed A here

Source C audio: The audio from Flow in 1, Flow in 2, Flow in 3, Delayed A or Muted A can be switched to during a cover event

PROGRAMME DELAY

Source A programme delay adjustable in steps of frames

Minimum delay: 0 frames

Maximum delay: 600 frames, which is:

• 25 seconds (1080p23.98, 1080p24, 1080PsF23.98, 1080PsF24, 2048x1080p23.98, 2048x1080p24, 2048x1080PsF23.98, 2048x1080PsF24)
• 24 seconds (625i, 1080i50, 1080p25, 1080PsF25, 2048x1080p25, 2048x1080PsF25)
• 20 seconds (525i, 1080i59.94, 1080i60, 1080p29.97, 1080p30, 1080PsF30, 2048x1080p30, 2048x1080PsF30, 2048x1080p29.97, 2048x1080PsF29.97)
• 12 seconds (720p50, 1080p50)
• 10 seconds (720p59.94, 720p60, 1080p59.94, 1080p60, 1080PsF29.97)

Programme delay adjustments can be made live. The M-CLEANIT applies the adjustments slowly over time, with small delay adjustments therefore going virtually unnoticed. Increasing the delay slows down the video until the delay is correct, while reducing the delay speeds up the video until the delay is correct

EVENT AND RESTORE DELAYS

Switch/mute/blur delay: Set in seconds, this is the time before an initiated event occurs on the delayed output. This time is used as a reaction time for the user to react to improper content

Restore delay: Set in seconds, this is the time before an initiated restore occurs on the delayed output. This time is used to ensure that the cover length is long enough to cover the entire event

The 'delay to event' and 'delay to restore' timings can either be the same length or different, to suit all workflows. Setting a longer 'delay to restore', for example, adds some safety delay to ensure all objectionable content is covered

EVENT ACTIONS

Restore to delayed A: Action to initiate the restore to Delayed Source A. Timer begins and counts down the time in the 'Restore delay' setting; when timer expires the Cleanit output will restore to Delayed Source A. If using the SBB-4, releasing a button will initiate the restore timer countdown

Mute delayed A: Action to initiate an audio mute of Source A. Timer begins and counts down the time in the 'Switch/blur/mute delay' setting; when timer expires the Cleanit output will mute the designated audio channels. The 'Mute/blur A fade time' setting allows a mute fade time of 0 to 10 seconds. If using the SBB-4, pressing the Mute button will initiate the timer countdown

Blur delayed A: Action to initiate a video blur of Source A. Timer begins and counts down the time in the 'Switch/blur/mute delay' setting; when timer expires the Cleanit output will blur the video. User defines the amount of video blur applied (0-100) using the 'Blur A level setting, while the 'Mute/blur A fade time' setting allows a blur fade time of 0 to 10 seconds. If using the SBB-4, pressing the Blur button will initiate the timer countdown

Switch to B: Action to initiate a switch to Source B. Timer begins and counts down the time in the 'Switch/blur/mute delay' setting; when timer expires the Cleanit output will switch to Source B. If using the SBB-4, pressing the Switch to B button will initiate the timer countdown

Switch to C: Action to initiate a switch to Source C. Timer begins and counts down the time in the 'Switch/blur/mute delay' setting; when timer expires the Cleanit output will switch to Source C. If using the SBB-4 smart button box, pressing the Switch to C button will initiate the timer countdown

Override to delayed A: Action to initiate an instant restore to Delayed Source A

Override to B: Action to initiate an instant switch to Source B

Override to C: Action to initiate an instant switch to Source C

ROUTING

The flow output routing allows selection between the Cleanit output, Monitor output, Flow in 1, Flow in 2 and Flow in 3

MONITOR OUTPUT

One of the two outputs can be set to show the Monitor output, which allows the content to be monitored and is available as either SDI or IP

This fixed multiviewer simultaneously shows the Live Source A video, Cleanit Out video, Delayed Source A video, Source B video and Source C video – as well as the Event pending (yellow) and Event active (red) tallies. Audio flow embedded in the signal is Live Source A

VIDEO LOSS CONTROLS

The video loss controls allow the user to select what will happen to an output flow in the event that the input is lost. 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 flow

TEST PATTERNS

The test pattern controls allow the user to override an input and force the output flow 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 flow

SYNCHRONISER AND TIMING ADJUSTMENTS

Video sources are synchronised to common reference timing source

Choice of timing options:

• PTP (SMPTE ST 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
• SDI video input, where available (defaults to SDI 1)

Chosen reference is the global reference source for all inputs and outputs

There are up to ten 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 app will move down the list until it finds a valid timing reference source. When used with IP inputs, the SDI reference option is not applicable and therefore the reference will move to the next valid timing source:

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

(“PTP” means PTP Master>PTP Backup. “SDI” means SDI1>SDI2>SDI3>SDI4>SDI5 >SDI6, dependent on number of SDI available. “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

Ten frames of flow input video delay and ten frames of flow output video delay (adjustable in one frames steps) are available in addition to the M-CLEANIT's main programme delay

ANCILLARY DATA

All ancillary data (excluding audio) is passed from SDI or ST 2022 input to SDI or ST 2022 output. Audio is passed through unless muted or replaced by the operator

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

The SBB-4 is the recommended way of controlling the M-CLEANIT, but all the standard Crystal Vision control methods are available to suit all preferences

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 momentary and use a button press to initiate the ON action and a button release to trigger the OFF action. By default these buttons are set to Mute A, Blur A, Switch to B and Switch to C, but the customer can request any of the available actions to be assigned to a button. 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.
