DS10G Codec

Unlike other standards-based codecs on the market today, DS10G from Datapath is unique in that it has been purpose built from the ground up to cater for the demanding needs of ProAV applications primarily focused on delivering pristine image quality with near-zero latency.

Designed from experience

Datapath has long-established engineering expertise in video and graphics processing, leading the way since our first multi-headed graphics card in the late 1980’s, which offered best-in-class control room graphics to the financial sector. Today, we have pooled nearly 40 years of engineering expertise and resource together to produce a network-based transmission technology that offers the same level of graphics delivery that customers need and have come to expect from us over the years.

No compromise

For critical applications the choice of IP codec is often overlooked. Visual flaws in either color fidelity, resolution, transmission latency or compression artifacts can all lead to a poor user experience, or even worse, a misinterpretation of critical visualized data. DS10G from Datapath makes no compromise and guarantees control room operators get an optimum user experience every time. Whether graphical visualization data is delivered to the workstation from remote SCADA systems, GIS thermal mapping data, transport maps or even basic spreadsheets – DS10G delivers pristine visual detail every time.

How much bandwidth is needed for 4K?

With so many IP video codecs on the market it can be difficult to choose. Whilst some try to re-use their existing network infrastructure when entering the world AVoIP, others are realizing that upgrading their network bandwidth capabilities is the only true way to get a full quality experience.

Many codecs, particularly those that are optimized for 1G networks, are not suitable for demanding control room or medical applications where precise image detail matters. It is impossible to meet these exacting standards without sufficient network bandwidth to carry the required data. Even the most advanced adaptive error prediction algorithms cannot achieve pixel perfection in every scenario at a 12:1 compression ratio when sending a 4K signal over 1Gb network connection. However, with DS10G a much lower 12:10 compression ratio is needed for 10Gb transmission, so pixel perfection absolutely can be achieved. Not only can it be achieved, but it can be proven beyond doubt by mathematics and through the use of comprehensive bit-error testing.

Catering for the wider audience

The DS10G codec has been designed for use on 10Gb networks in order to meet exacting video standards. Users also need the capabilities for wider visualization of critical streams outside the local network, across multiple network infrastructures both inside and outside the facility, and to support remote working. This is why our DS10G based products have been designed to work in perfect harmony with our proven SQX technology to provide scalable managed delivery of 1Gb compressed streams.

With DS10G users have the choice of keeping the pixel perfection and visual detail where they need it, but without restricting access to feeds purely to those who have a 1Gb connection.

Singlecast, Quadcast and multicast

DS10G makes the very best possible use of each and every 10G network port connection, making the transition to 10G networking more cost effective and efficient than other available options. Unlike other 4K lossless encoders on the market that need a 10G port connection for every input stream or output stream in the system, DS10G has some clever tricks up its sleeve.

Despite the advent of 4K, we recognize that many video sources and displays continue to run at HD resolutions. Using DS10G’s unique Quadcast capability, four independent HD signals can be ingested through the network over a single 10Gb connection with independent output routing to the displays. This means that with DS10G, switch ports are always used to their full potential and customers don’t pay for 10G switch ports that are only running at 25% bandwidth utilization when dealing with HD signals. Alternatively, when the codec is handling 4K signals it uses the full 10Gb bandwidth to deliver a single stream at optimum quality (i.e. Singlecast).

One of the major benefits of any AVoIP system is its scalability. DS10G streams are multicast on the network by default, meaning that any source can be viewed from any endpoint any number of times without putting additional pressure on the switch and keeping network ‘chatter’ to a minimum. Once a source is on the network it is available for viewing anywhere and by all, limited only by the users viewing and access rights.
