IMTC SuperOp! 2010 – Continuing Advancing Interoperability

So the time is finally on. Long-planned and even postponed (thanks to the Iceland volcano with the unpronounceable name), IMTC SuperOp! 2010 is taking place in a small town of Jesi, near Ancona in Italy, June 14-18. Big Thank You to our hosts RADVISION Italy, Aethra.Net and Telecom Italia, as well as our sponsors Tandberg, Polycom, Cisco and Vidyo!

What is behind the name “SuperOp”, which sounds both big and cryptic at the same time? SuperOp!, a.k.a. “major interoperability event” is an annual gathering of IMTC member companies, getting together to conduct interoperability testing of IP Multimedia Communications solutions over one big network setting. Our First SuperOp!, took place in 1997, and then continued annually. SuperOp!’s goal is to help engineers to advance the level of interoperability of their companies’ products. Latest and greatest solutions, quite often include simply unreleased [yet] versions of software and hardware, that are tested for interoperability with each other. One can truly look at the SuperOp! as a giant development lab, where experts from the competing (sic!) companies work together to improve their products.

Is SuperOp! still relevant? It seems that interoperability is a key word, coming from every corner of the communications industry. From newly formed alliance, UCIF, which promises to focus on interoperability of unified communications, to the just announced Apple’s iPhone 4, which will provide video communications based on open standards, interoperability is a key topic for the whole industry. And interoperability is the major area where IMTC made the difference from day one – iNow profile and H.323 Forum Certification Program, numerous improvements in mobile video streaming standards and technologies, adapted by 3GPP, 3G-324M interoperability testing plans used by GCF as a foundation for certification program for mobile video telephony, MONA standardization in ITU-T, SIP Parity (video control enhancements over SIP)  definitions which are now making it into IETF, and latest efforts in the GSMA VoLTE and Telepresence multi-streaming and TIP – these are IMTC contributions into making technologies better in the practical hands-on terms.

So what will be happening at the SuperOp! 2010? First of all, there will be a lot of interoperability testing done in all of the Activity Groups – video conferencing using both SIP and H.323 (thanks to the year long hard work of the SIP Parity activity group, SIP-based video communication is becoming a reality), IP video streaming in PSS Activity Group, mobile video conferencing using 3G-324M. Then there will be a traditional SuperConnect – all-participants with all the video conferencing devices, always done on the last day of the event. In addition to this traditional activities, this year IMTC will also conduct Telepresence Workshop, where industry leaders from Cisco, Polycom, Vidyo, AT&T and others will present current state of affairs in the Telepresence Interoperability and lay out the plans to make Telepresence ubiquitously interoperable (audience poll: who thinks it is achievable, raise your hands J). All in all, we are looking at a busy week, a lot of work and a lot of fun! IMTC is open for every company interested in improving interoperability of their products (and enjoying the process at the same time!), so … c’mon over!

HTML 5 & Standard Web Video Delivery – A flash killer?

A topic still very relevant today is the HTML5 vs Flash debate, fueled by devices like iPhone and iPad that lacks Flash support (and, apparently are more open standard oriented).

HTML 5 is still under development and the future looks very bright – Carl Ford (Crossfire Media) and Joe Hildebrand (Cisco) talks about HTML5 and the future of web video delivery.

The Technology Behind iPhone 4 FaceTime Protocol – Standards & Apple

Apple announcement of FaceTime, their new video telephony solution, included various standards: H.264, AAC, SIP, STUN, TURN, ICE, RTP, and SRTP. If this is the case, it would offer great start for interoperability, as the very same standards are widely used by the modern video communications solutions by majority of the vendors.

Here’s a short explanation on the role of each standard:

H.264 – one of most prominent video compression standards in use today. Used by every major and minor video communications solution today, from the mobile video to desktop to room system to Telepresence system. Has AVC (advanced video coding) and SVC (scalable video coding) profiles – AVC profile is what is widely used and interoperable today, while SVC profile holds great promise once interoperability will be established. Already used on the iPhone and other i-devices.
AAC – advanced audio coding standard. Widely used today in audio and video communications and has established interoperability. Used by iPhone and other i-devices.
SIP – Session Initiation Protocol – de-facto standard of IP Communications solutions, including both Voice and Video communications. Used by majority of video conferencing vendors, such as Cisco, Tandberg, Polycom, RADVISION and more. Also one of the core standards in 3GPP IMS ( IP Multimedia Subsystems) communications.. Highly interoperable, however, lacking dedicated definitions for IP Video Call Control – IMTC SIP Parity Activity group developed set of best common practices and use cases to improve interoperability of SIP –based video communications.
STUN, TURN and ICE – typically used together to support Firewall and NAT traversal functionality. STUN ( Session Traversal Utilities for NAT) allows to map internal IP addressed behind the NAT to the external IP addresses. TURN (Traversal Using Relay NAT) is used in rare cases where STUN doesn’t provide a solution. ICE (Interactive Connectivity Establishment) is used as an umbrella standard utilizing STUN, TURN, uPnP and others in order to find possible way to transfer the NAT and Firewall.
RTP, which stands for Real-time Transport Protocol, is used in Voice and Video over IP implementations to carry over real-time media and collecting of the statistics, such as jitter and latency, which in turn allows to implement better quality solutions. Today used by absolute majority IP voice and video vendors.
SRTP – Secure RTP, profile for secure RTP communication which supports encryption, message authentication and integrity. Widely used in both IP Video and Voice implementations.

We are looking froward for further implementations of this new technology. Things are getting very interesting in visual communication products.

Yesterday, Steve Jobs, Apple‘s CEO, Introduced FaceTime , a video telephony solution for iPhone 4. It is based on  open standards and integrated in next generation iPhone as a simple to use video telephony product.
Apple is known for its ability to revolutionize industries. iTunes, iPod, iPhone and iPad – all changed their respective markets.

We expect that visual communication, delivered in Apple’s style – simple, reliable and sexy – will do exactly the same for mobile visual communications as the whole.

The introduction of FaceTime by Apple is a vote of confidence in visual communication, and IMTC is certain that it will increase the uptake of mobile video telephony.

IMTC has the biggest visual communication expert pool, as well as rich history of ensuring interoperability and promoting adoption of standards-based visual communication technologies. From mobile telephony, to desktop video conferencing, to Telepresence, IMTC has the most active interoperability and testing groups in the industry.

As such, we are excited about yesterday’s news, and looking forward to support FaceTime adoption as an open industry standard.

Anatoli Levine, President,  IMTC

HTML 5 and  its effect on the industry will be discussed at IMTC virtual conference “2025″. For more details check this link.

Apple doesn’t like Flash. We know that already. Steve Jobs recently called Adobe lazy, and we all know that iPhone and iPad doesn’t support Flash. But the story is a bit more complex than that.

Apple’s opposition to Adobe is linked to HTML 5 – an open standard that would enable developers to use open formats to deliver rich media experiences. As such, this format is a threat on Adobe. And as Apple Insider analyzed in a great post about Flash vs. Apple: [Read more...]
