Iphrame Overview

Iphrame is a software-based framework that combines IP, ASI, and SDI signals as both inputs and outputs to provide a real-time production system.

Iphrame handles video, audio, and graphics, and because it runs on standard IT hardware or VMs, it dispenses with much of the equipment and resources traditionally required. This cost-saving solution offers the opportunity to televise more events at the highest possible quality for less money.

An added advantage of an IP-based solution like this is that operators can be stationed remotely and can make real-time switching decisions using proxy versions via the cloud.The number of staff required at the event site can, therefore, be minimised with the result that media companies can reduce expenditure on travel and accommodation.

Remote architecture powered by TimeLock

Our award-winning remote architecture exploits Iphrame’s ability to be monitored and controlled from anywhere in the world without needing high-bandwidth links to bring back high-res feeds to a central location. As a result, fewer staff are needed on-site and events can be remotely produced using lower bandwidth links, which is great news for your budget. By deploying Iphrame in parallel to a traditional production architecture, the high-value production can be carried out in the usual way whilst alternative streams or other tasks can be handled using the latest flexible technology at a significantly lower cost. In such circumstances, Iphrame can also act as a backup or disaster recovery solution should the main production platform fail.

The whole Iphrame range is 100% software, only utilising dedicated hardware when SDI or ASI connectivity is required. A radical alternative to the way outside broadcasts are planned and implemented, Iphrame Remote can drastically reduce the cost of broadcasting large international events.

Iphrame’s TimeLock Functionality

Key to the operation is Iphrame’s TimeLock functionality, which ensures all sources and processing is accurately timestamped using PTP reference clocks. The latencies, which are unavoidable with any remote or IP-based solution, are carefully measured and compensated for.

Timestamped Proxy Feeds

TimeLock enables control surfaces to operate using timestamped proxy feeds at a known time-offset so that switching decisions can then be performed remotely in high-res on the exact frame the operator intended. Iphrame even provides an instant simulation of the mix generated from the proxy feeds, giving the operator an instant visual response as if they were controlling a local device.

Iphrame Remote works by consolidating all SDI and IP sources at an event within a server deployed at the event site. The server buffers these streams, generates proxies of them and pushes them back up into the cloud.

From here an operator can use an Iphrame client to view the proxy streams frame accurately and make switching decisions which are passed back to the remote site. The Iphrame Engine then generates a high-bit-rate, high-quality output, ready for lightning-fast transmission to multiple platforms across the globe.

1-Stage Mixing

1-stage remote controlled mixing is the basis of our simplest Iphrame offering, Iphrame Flyaway.

However, for higher value productions it is likely that video/audio source generated local to the production team may need to be used (e.g. External graphics, locally edited content). To enable this a second stage vision/audio mix can be performed at the production centre and thanks to Timelock this can be frame accurately switched without the operational staff treating remote and local sources differently.

2-Stage Mixing

This general 2-stage architecture formed the basis of a trial with BBC Sport for Euro 2016. This concept can be extended to allow mixing at multiple locations and in multiple time offsets bringing together sources from multiple events through limited bandwidth links, maintaining frame accurate control at each stage. Multi-stage mixing solutions are customised to specific customer requirements so are sold as Iphrame Enterprise.

More detail about time compensated production and how it compares to other methods is covered in the presentation video below.


Ed Calverley at NAB 2017 – Time compensated remote production in the all-IP world

This session looks at how the current standards work is enabling true end-to-end IP-based production and how standards such as SMPTE ST 2110 enable systems to interoperate in a much more flexible way than was possible with SDI. As an example, during the Euro 2016 soccer tournament a time compensated 2-stage switching solution was frame accurately controlled over a limited-bandwidth link.
