Touching the Future: True Web Browsing of Content, 3D, Super Hi-Vision
Changing the Games With Game-Changing Technologies
Televisa was one of the broadcasters who used the IPBrowseWeb host broadcaster
One axiom of big-event broadcasting is to use established technology.
The reason is obvious: There are millions or billions in advertising on the

churning out a few hundred hours of programming using a VTR recording
infrastructure at an event like the London Games, rather than the 5,000 hours
or more of content possible in a modern server-based environment.
At something like the London Games “pushing the envelope” does
happen. These advances are incremental, not experiments but something more akin
to “proofs-of-concept” to move the industry forward.
saw the debut of several new technologies, and perhaps the most important was
the deployment of true Web browsing of content. This could be a game-changer,
something that will make the split production of large events much easier and
thus more common in the next few years. This will allow broadcast personnel to
stay in their home country yet still access the live feed and all logging
information as it’s being reviewed on-site. The potential travel and housing cost savings
NBC had a 3DTV demo running in its IBC facility.
The technology that makes it possible is EVS’ IP
Web software, an extension of the company’s IPDirector software that has made
browsing and content exchange a simpler affair for broadcasters working on big
sporting events. Producers can now see content within 1 second of a live
recorded feed through the Web, create their clips and rough cut edit before
importing just what they need locally.
Cost-effective, simpler split production -- the subject of many complex
and bandwidth-intensive Games facility designs for more than a decade -- may be
on the immediate horizon.
Several broadcasters tried this
host broadcaster service, called IPBrowseWeb,
in London. One, Televisa of Mexico, is profiled here. Televisa personnel in Mexico could browse
content, create clips and even retrieve content with minimal delay over
standard Internet connections.
London Games, broadcasters created and exchanged more than 3,000 clips using IP
Super Hi-Vision at a VIP reception in Washington.
London was the first Games that had a 3D
component, with more than 230 hours produced from the content captured by 33
cameras and six ENG crews. A turnkey 3D channel with English commentary was
available for 16 hours each day.
All of this was piped
through three dedicated trucks connected to their own production centre within
the IBC. The bandwidth and capacity of the latest EVS XT3 servers was put to
good use here.
Super Hi-Vision was also featured in
London, with an NHK truck and three cameras on site. Six public 50-foot screens
in the UK and Japan joined two VIP test screens at the IBC and in Washington.
The world feed was sent to Japan on a series of private academic networks,
while it’s was piped around the Olympic network via dark fibre and to the UK
screens as two MPEG transport streams.
and searching for content in a high-volume operation is critical. In London, host broadcaster OBS supplied the “Broadcast Data Feed”
to RHBs. This feed had within it all the logs from the massive OBS pool
of EVS servers, and more. This could serve as a supplement to a broadcaster’s
own logging and add value to all host assets, making them easier to find and
providing more information.
