Microsoft mugged over VC-1 codec patent terms

Self-inflicted victory


Comment We meet people on the various IPTV, mobile TV and web video circuits who always comment that VC-1, after a flying start, has fallen back and that pretty much these days the codec of choice is either VP6 from On2 Technologies for web video and H.264 for everything else, with no VC-1 in sight.

Just over three weeks ago the MPGE LA issued a final license for the Microsoft-inaugurated VC-1 codec, after forming a group to assess essential patents and to discuss terms for it, back in March 2004, the process taking precisely three years.

The license may in fact only be a license by which Microsoft can pay everyone else fees. There are no less than 16 separate companies that are deemed to have patents that are essential for VC-1 to work, the latest addition to the 15 company list that was first issued last August, being Korean number three handset maker, Pantech Curitel.

Between them they speak for 125 separate patents that are listed in the license, and a total of two of these are allocated to Microsoft. Every other supplier of essential technology including Daewoo, France Telecom, société anonyme (which presumably includes patents from close associates of France Telecom also) Fujitsu, Philips, LG, Matsushita, Mitsubishi, NTT Pantech Curitel, Samsung, Sharp, Sony, Telenor, Toshiba JVC, have more patents at stake that Microsoft (except for two of the above) and many of them have many more.

Effectively Microsoft has been mugged by the attempt to make its VC-1 technology a standard through the Society of Motion Picture and Television Engineers. In so doing it had to reveal how its codec technology worked, and offer a license, and in going to the respected MPEG LA as a patent pool agent, it exposed its technology to all the know how that went into licensing the MPEG 2 and MPEG 4 Level 10 AVC/H.264 codec that has stolen the market.

Usually all of the combatants (essential patent holders) will argue for some basis or other for splitting the royalty stream, and these rules are not public and they are not always the same. But as a general principle the more patents you hold, the bigger your slice of the patent pool pie. Now that’s not absolute, but it can be an indicator.

On that basis every company except Telenor and Sharp will end up getting more money when VC-1 is used, than Microsoft. Of course Microsoft can charge what it likes for any software implementation of its own, but since it has always chosen to “give away” its codec with its media player, this means that it has to cover any licensing bill for patents out of virtually zero direct revenue.

Microsoft's humbling over VC-1 shouldn't be under-estimated. When we last heard a Microsoft official speak about this back in 2004 they said that everyone should use VC-1 because it was charging less than MPEG4/H.264, but that was back when it thought that it owned all of the technology inside the codec.

It's no wonder that the use of VC-1 has fallen by the wayside. Why would Microsoft push it? The more successful it is in getting other people to use it, the more its rivals in the consumer electronics space get paid royalties.

When the patent pool was first put together and the negotiating began, both Sony and Philips were known to be considering taking legal action against Microsoft. They had already been successful in taking Microsoft to the patent courts in the US, over DRM, in support of their acquisition Intertrust, where they won a $440 million settlement. In a way that’s more of less what they’ve won here.

  • US, UK, Western Europe fail to hit top 50 cheapest broadband list
    Syria, Sudan, Belarus, Ukraine came top. Are you starting to see a pattern?

    In an analysis of 3,356 fixed-line broadband deals in 220 countries, price comparison website Cable.co.uk found that the UK has the 92nd cheapest internet, beating the US, which came in 134th place.

    Based on 41 packages, the average cost per month for broadband in Britain came in at $39.01. Stateside, this rose to $55, from 34 packages measured.

    For these bulwarks of western democracy, 92nd and 134th place isn't particularly impressive. But if you really want to shave the dollars off your internet bill, you have a number of options.

  • The right to repairable broadband befits a supposedly critical utility
    A bolt of lightning has caused me days of misery, because the fix requires too much proprietary tech

    Column I heard an electric discharge, a bit like a Jacob's ladder, immediately before a deafening crack of thunder. I'd never been so close to a lightning strike! All of the lights in the house went bright, then dimmed, then went back to normal. "Uh-oh," I thought, "I'm in trouble now." Everything in the house had been hit by a nasty surge and the oft-spoken aphorism that broadband services are now a utility to rank with water and electricity was suddenly very, very, real to me.

    But it was electricity I worried about first. I use top of the line surge protectors so my most sensitive devices – computers and monitors, of which I have many – all seemed fine. But I'd overlooked two other connections that come into nearly every home: the antenna and the phone line.

    My television seemed to have taken a direct hit. It still worked – mostly – but appeared unable to receive any digital broadcasts. That circuit, lying on the other side of the antenna lead, likely took a big hit from the lightning strike. But the rest of the television seemed fine – at first. After a few days, and several spontaneous reboots, I began to intuit that devices don't always immediately fail when hit by lightning. Sometimes they gradually shed their functions and utility.

  • Telecoms growth forecast for 2022 may be optimistic
    Analyst view: 4Q21 drop plus strains from war mean component shortages drag on

    The telecoms kit market had a good 2021 with revenues close to $100bn, up more than 20 percent since 2017, but growth is now slowing, according to analyst Dell'Oro Group. Huawei is also starting to feel the effect of sanctions, but still leads the global market by a fair margin.

    However, the Dell'Oro Group's prediction of slightly less growth for 2022 may turn out to be optimistic amid warnings that the Ukraine war is already having an impact on the fragile supply chain recovery.

    Dell'Oro's analysis is based on the telecoms market sectors it monitors, including Broadband Access, Microwave & Optical Transport, Mobile Core Network (MCN), Radio Access Network (RAN), and Service Provider Router & Switch.

  • Fibre broadband uptake in UK lags behind OECD countries
    Not very 'world-beating'

    Optical-fibre internet now makes up 32 per cent of fixed broadband subscriptions across the OECD countries, and is the fastest growing broadband technology. However, there is a mixed picture with cable still dominant in the Americas and the UK still predominantly DSL.

    These figures come from an update to the OECD's broadband portal, indicating that fibre subscriptions grew by 15 per cent across the OECD countries between June 2020 and June 2021, with demand for faster internet speeds as employees worked remotely due to COVID-19 restrictions cited as one reason.

    Fixed broadband subscriptions in OECD countries totalled 462.5 million as of June 2021, up from 443 million a year earlier, while mobile broadband subscriptions totalled 1.67 billion, up from 1.57 billion a year earlier.
