Embedded Linux All Around You

Linux is appearing in the wild more and more – unbeknownst to most consumers. If you have a Linksys router, it’s the box’s embedded OS. If you have a Volvo, the engine management system is Linux-based. It’s even employed to enable pacemakers to transmit data wirelessly to warn of a heart attack. There’s even a Linux-based watch, but Sesame would kill me.

Linux-based kernels are favoured in these smaller systems for three key reasons:

  • they make the most of limited hardware
  • Linux is cheap (often free)
  • it is well documented and understood, not relying on proprietary code that is protected

We’d like to gather together some links here for you to explore, to find out more about Linux in the devices you use every day.

Linux is not without its problems though – some of the code in the kernel is flaky to say the least, and many things that users take for granted, such as Firewire support and drivers for common hardware, are either nightmarish to enable, or just non-existent. However, kernel support for hardware is improving and much of the more imaginative code is being weeded out rapidly.

Away from the purely embedded side, Sony have had success with the Linux development kit for the PlayStation2 – a product that only demonstrates how flexible the operating system really is. Sony produced the kit to encourage home development for the system – much like the Yaroze version of the PS1. Sadly, though, we can’t remember the last time we popped into Game and bought a title that was written on either dev system – to an extreme with the PS2, the two platforms are enormously complex and hardly the sort of things that bedroom coders will be able to produce a top-flight title with. Oh, bring back the days of Braben and Bell and Elite.

With the number of devices growing daily, Linux seems to be expanding just as fast as the whole Digital Lifestyles world – and we’ll keep you up to date with the pros and cons of this fascinating growth area.

Linux is popping up all over

Preview of the Connected Home event, April 2004

By Ian Johnson, Director, Junction Ltd.

After what was perceived to be a relatively slow start for the industry – things are finally making progress.

The Connected Home Conference – September 2003 – focused on partnerships to really push the industry forward. The technologies are in place and the service aggregators are ready – the challenge is communicating this to the marketplace.

As commented by the previous review of the September event, there were a lot of top level – strategic overview speeches that really gave an important insight to what each sector was doing and allowing networking opportunities. This is great for those at a senior strategy level, and we have retained some of this for the April event. However the practical element, the hands on stuff, will also be focused on much more.

Partnering with Cedia, we’ve introduced an important section on construction and installers with a session chaired by Steve Moore outlining the latest practical projects. Also, there are two interesting speeches from Abrocour (who have partnered with the likes of Berkley Homes, Intel, HP and Microsoft to help deploy their services), and ConvergeX who are partnering with Linden Homes to launch a raft of new services.

The April event will also have some very interesting insights and learning from the US market from companies like GE Interlogix, Windows eHome, and Whirlpool, and Parks Associates all venturing over from across the Atlantic.

So, what are the current market trends?

Abracour CEO Sam Sethi explained to Digital Lifestyles: “Wireless solutions are becoming faster and safer, and are gaining in popularity with consumers, as people want access to their data, video and audio on the move. As the government pushes ahead with its new Building Regulations (Part Q) stating that all developers should provide the capability for broadband Internet in new homes, we expect to see a big uptake in housing developers installing wireless.”

This has important implications for the housing market, as Sethi pointed out, “Housing developers are realizing that wired solutions are costly and cumbersome, and that wireless home network solutions offers house builders and architects a cheaper and more efficient alternative.” (For more information on Abrocour, see the link below.)

This in turn provides a new angle for the way homes are marketed and the perceived value add it delivers for consumers. Matthew Bramble, Technical Director, Opus Technologies described that, “Its now widely accepted that modern entertainment technology genuinely attracts new home buyers and adds to a home’s perceived value. We recognized early-on that home builders were the key to getting this exciting technology into the home and have consequently striven to design products ideal for new build. We have made it a priority to partner with new-home builders world-wide and have enjoyed particular success where we have focused on creating customized solutions.”

That’s exactly what the connected home event is about – bringing together industries, and providing a useful link between home builders and technology companies, and enabling them to partner to deliver services to the marketplace.

We began the September 2003 event by defining ‘What is the connected home’?

“We believe it should be based on real people, living in real homes and not on technologies or esoteric finances, or lifestyles that don’t mean anything to people out in the street. It’s about connecting things simply and wherever I want to connect them in my home,” said David Sales, Director of Home Communications, BT.

Strategies for the market

The 2003 conference stressed that by using an ecosystem strategy to develop the home technology market – as an end-to-end service experience for the customer – it would make it simpler for them to build that system themselves.

Many speakers were thinking holistically about the broadband ecosystem in the home. They viewed broadband as feeding that system, at the heart of the connected home – bringing things alive. The Connected Home must feed consumers desire to work, play, and relax and even to be able to monitor all things going on in the home. Broadband was seen as important in setting this market alive, however, ‘partnerships’ are the key to driving the market forward.

Thomas Hott,, CEO of ProSyst Software AG, told me: “One of the discernible trends at present is a movement away from piecemeal home networking offerings to more comprehensive solutions. People realize the need for an integrated platform to connect devices of any kind and regardless of who produced them. Consequently, a standards-based approach is in the interest of all value-chain participants – from manufacturers to service providers and end users.”

What will drive the connected home?

In addition to forming alliances, many see entertainment in the connected home as the main driver. It was commented that people are willing to pay to enjoy themselves and that generating excitement and enjoyment in these services, with easy to handle technologies would be key.

“‘Enhanced features’, costs savings and ease of use are really the things that will drive this market forward” explained Michael Gannon, Senior Market Manager, Motorola Broadband. Gannon. “At the moment we are seeing competition is greater in Europe than in the US, in the connected home arena. The competition between DSL and Cable as the enabling technologies are driving the market, and we are seeing the acceptance of connected home products going down well in Europe, due to this competition. This is driving the market slightly more than in the USA.”

Looking at the different types of product on offer, “Numerous attractive new smart home products have reached the consumer in recent months. Through major contributions to such products – including a Motorola smart home gateway, the Philips iPronto and Bosch Siemens’ serve@home solution – ProSyst has played a crucial role in furthering this market with its OSGi-based end-to-end solutions,” outlined Daniel Schellhoss, ProSyst Software AG.

In order for the networked home to be a success there has to be a mass market. In the US the connected home market came to life in the retail market and online, whereas in the UK retail has not yet proved to be a very strong route to market. Many asked whether the UK retail industry would be supporting this market growth in a similar way?

Delivering Services

Entertainment, home care, remote control and security services are all becoming more important for the consumer, and the focus on these services was well received. Also, important other markets emerged in home care and control. This was highlighted by the West Lothian Council case study. This showed us the opportunity to embrace the potential of the technology in the way of changing lives of citizens, and helping to tackle social inclusion.

To make services available for the mass market, many were convinced something has to change in the market – and this was likely the role of the home service aggregator. Many cable, Telco and utility companies are looking to develop this role in the market. This involves combining portfolios of services and delivering this in an easy way to the end customer which makes higher quality of service.

“Manufacturers look for new ways to not only reduce their maintenance and development costs but also to enhance their market share by offering new and attractive services, that constantly grow in volume and content variety. An important factor that affects not only the manufacturers and operators, but also the consumers’ interest in new services and customer loyalty is the delivery, installation, activation and maintenance of new applications and services in a safe manner. By providing simple and convenient solutions we reduce barriers to adoption that remove the burden of complexity from the consumer’s hands and help manufacturers to reduce maintenance costs up to 30%.”, explained Dr. Susan Schwarze from ProSyst Software AG.

Understanding consumers

IBM outlined its role in understand the behaviour of consumers when dealing with complex technologies. “What is the reason to use these technologies – it’s all about services” commented Ralph Baral, Smart Home WW, IBM.

Understanding what exactly the consumer are doing, their behaviour and how much time they are spending using these technologies and how it is effecting their lives. The general consensus among speakers was that the consumer is becoming far more technology literate, and this is influencing the way in which technology and media companies configure their services.

Whilst they are becoming more technology literate, most speakers emphasised the need to keep the complexity for the end user at the lowest level possible – and that it was still the problem today.

April 21/22nd, Connected Home, 2004 event

The April event this year will receive yet more focus on service deployment and provisioning in the industry, but importantly will also include a focus on the construction industry. Four of the leading UK property developers will be speaking at the event, and offering their views on the different types of connected home project they have been undertaking.

ConvergeX, the digital homes solution company, is one such organisation partnering their home control middleware software with leading UK property developer Linden Homes.

Jostein Svendsen, Managing Director of ConvergeX commented that, “2004 is the year where Digital Homes will take center stage as many major companies are moving into the market place and positioning themselves to drive the market forward. But even if the larger players will supply the devices, the innovation and applications will found in the smaller companies. This is where Europe can play a main role – delivering leading edge applications to enable the digital home revolution.”

This focus on the building industry was something emphasized by Opus Technologies, and exhibitor at the 2003 event. Matthew Bramble, Technical Director, Opus Technologies described that, “Its now widely accepted that modern entertainment technology genuinely attracts new home buyers and adds to a home’s perceived value. We recognized early-on that home builders were the key to getting this exciting technology into the home and have consequently striven to design products ideal for new build. We have made it a priority to partner with new-home builders world-wide and have enjoyed particular success where we have focused on creating customized solutions; solutions which are not only product but a fully realized support package which includes marketing, project management and installation services.”

Svendsen from ConvergeX echoes this sentiment, ” We look at the market and are tying up with players in a number of ways. We are initially targeting property developers and authorized re-sellers and will later license the software to be installed in various home devices. Even though we are starting deployment in the mid to upper end of the market – we will ultimately achieve mass market adoption by being available on millions of devices being sold to the home.”

Summary

The broadband home is here today, and the connected home is coming. Everything is available today, we have connectible devices and service aggregators – the question asked was how do we move forward to this integration environment? The technology is already here, the big challenge is how we market it to the right people? How do we communicate to the marketplace?

Jostein – “The connected home of the future is not about having massive amount of technology on display. The good solutions are the invisible ones, the ones that always there to help you and make your life easier, but you don’t have to think about them.”

Consumers are getting used to the concept of the home network. “The networked home really has a future, but as far as the mass market is concerned I think we really have to find out what that is” summarised Andrew Mullen, General Manager Communications and new technologies, LG Electronics UK.

Convergence is really re-defining the industry today as connected devices are emerging and as Mask Ossel, VP and General Manager, EMEA, Echelon outlined, “many companies underestimate t he speed of change.”

As we plan for the next connected home, April 21/22nd 2004, we are considering the comments throughout out the 2 days, and are looking to help the industry understand the issues that it faces, and helping drive this market forward.

We look forward to seeing you at The Connected Home 2004.

XBox: Huge US Price Cut

Microsoft have generally been slower to cut XBox prices in the US than they have in Europe – possibly because it started out at a much lower price there in the first place. Now, they’ve made a massive cut – possibly because sales of video games in the spring/summer months traditionally slump.

The XBox has been cut by $30 (UK£16.50, €24.60 ) to $149 (UK£81.75, €122.12). This makes it cheaper in the US than a GameBoy Advance SP is in the UK (a GBA-SP is currently UK£84.99 on Amazon, making it nearly US$155).

Microsoft are planning similar price cuts for Canada and Mexico, but would not say if other markets could look forward to a discount.

Many games such as Counter Strike and Project Gotham Racing will also see price cuts to $29.99.

Microsoft also released a rather striking limited edition “Crystal” XBox in the UK this week – it’s entirely transparent and is only £139, which sounds like good value until you compare the Dollar price with the new US price for the ordinary model (US$253, €207).

Asus Announce WiFi Hard Drive Enclosure

Asus have produced a hard drive enclosure with a built in 802.11g adaptor and two 10/100 Ethernet ports: the WL-HDD. At 54 Mps on the wireless connection, it’s not really fast enough for heavy corporate use on the 802.11g connection only, but it is ideal for a home server – and is priced accordingly: approx US$150 for the enclosure, you supply the ATA-100 drive.

Like many network attached storage systems, the device is managed through a simple HTML interface, enabling administrators to grant access to files on the drive.

Matt Jones comes up with an interesting idea

Ready-made MythTV Media Centre/PVR Available

Based around the MythTV open source personal video recorder package, Australian company Development One (D1) are selling a home media centre from AUD$1800 (~UK£738).

The HMC has all the usual features: DVD/CD playback, audio jukebox, PVR functions, electronic programme guide – but it’s the first MythTV/Linux appliance we’ve seen available commercially. It runs Redhat with a custom 2.4.22 kernel, and MythTV, the popular GPL PVR software. The D1 website makes no mention that the HMC is Linux based – presumably as it’s being marketed as plug and play, and Linux has anything but a plug and play reputation.

The HMC comes in a Shuttle form factor case with LCD status panel and even has a remote control for accessing commonly used functions.

Interestingly, the MythTV feature that enables users to skip ads has been disabled, but there’s a quick hack to get round that.

MythTV is still in early development stages and still has a few show stopping bugs in it – it can quit unexpectedly, even on well-behaved systems. It will be interesting to see how consumers get on with an appliance that could potentially dump them out to a Linux command prompt.

We’ll have more on MythTV in the future as the application develops.

Sony to use Electonic Paper Display in eBook

Two exciting things rolled into one: an new eBook reader from Sony, and it employs a new display technology that we’re really looking forward to getting our hands on. The LIBRIe is the first consumer application of their revolutionary display, going on sale in Japan next month.

The 170 pixels per inch display is made by Philips, and employs a technology developed by E Ink. It can be read at any angle and appears just like paper, with very sharp black/white contrast. Because the reader only uses power when you “turn” pages, users can view more than 10,000 pages on four AAA batteries.

Sony state in a press release that the LIBRIe can store 500 books at a time, but don’t say how much storage the reader has, or if it can be expanded. We hope that device can be expanded (bets on a MemoryStick slot, anyone?), but our main wish is that the LIBRIe isn’t confined to displaying files in a proprietary format – we want something we can read plain text and Word/OpenOffice documents on. We were once shocked to see that the eBook version of a Stephen King novel on Amazon was considerably more expensive than the hardback – even when postage was included. Now Rocket know why their reader didn’t sell too well.

We’ve long wanted a proper eBook reader here at Digital Lifestyles. We even considered importing one of the Rocket eBooks when they first appeared, and occasionally when my eye drifts to the huge stack of also huge books by my bedside, I imagine how good it would be to have them all on one device, slightly bigger than A5 without the annoying rustly page turning and the realisation that the book I really fancied leafing through is in another room.

Sadly, PDAs, proprietary formats, expensive devices, expensive content, lack of marketing meant that the eBook dream never quite took off. Hopefully, since the LIBRIe is backed by the Sony brand, it’ll fly this time.

If it becomes available in the UK/USA, we’ll buy one and do a review here.

3 Announce Videotalk to PC

We have to admit – it’s quite compelling: with 3’s new Videotalk to PC service, subscribers on the 3 network can call any PC with email and a webcam and have a videophone conversation. The service will roll out in Australia shortly.

It’s a great idea – and will help spread the use of 3G video phones because now you have more than just a few other 3G video phones to talk to.

NEC’s 606 and 808 handsets are already compatible – and a software upgrade will allow Motorola A920 users join in. PC users need a webcam and need to register to use the service before they can take calls.

The service is in use in Italy, and about to launch in Hong Kong. Calls are charged at national Videotalk rates.

Sony Launches Hard Drive for PlayStation2 in US

Sony have finally launched the PlayStation2 hard drive in the US, some might say a little late into the console’s life cycle. The drive is identical to the one that has been shipped with the Linux kit for the last 18 months – but then the drive in the Linux kit wasn’t compatible with game saves or downloading content.

So why now? The hard drive is needed to play Final Fantasy XI, the first online iteration of the baffling (hey, only if you don’t play it) role-playing game, and sales of the FF series more than justify marketing a $99 peripheral that was already in production. The drive comes with FFXI pre-installed, and players will be able to sample the game free for 30 days – but will have to cough up $12.95 a month as a subscription to keep going.

But that’s just one game – there will be a huge range of downloadable content and media available for subscribers: new levels, music, perhaps even full-length films. Given that the average game save is about 200kb and you could fit roughly 200,000 of those on the new disk. Sony obviously have a lot planned – and if the peripheral takes off, suddenly Sony has a potential installed base of more than 70 million broadband-enabled, game playing media hubs in living rooms and bedrooms around the world.

We’ve been quite looking forward to the hard drive, the endless fiddling about with memory cards is annoying: one card for RPGs, one card for all our EyeToy pictures, and Bahamut help me if I lost Sesame’s card with her Grand Theft Auto and Silent Hill saves on it.

CeBIT: Digital Camera Market Expanding Rapidly

The digital camera market has expanded rapidly in the last five years. In Europe alone, CAP Ventures estimate that sales will from from 14 million sold in 2003 to 26.3 million in 2008 – and by then the market will be worth some €20 billion. Digital photography has already changed the market – Kodak will stop making non-disposable film cameras and concentrate on fun film cameras and digital devices. It won’t be long before other manufacturers follow.

Kodak and Olympus used CeBIT to launch new additions to their digital ranges. Kodak is showing off the Easyshare LS743 and LS753, with 16mb x 4 megapixel and 32mb x 5 megapixel resolutions respectively. Olympus are demonstrating their ì410 camera – this new camera features TruePic turbo which they claim improves image clarity, contrast and colour.

The growth in digital cameras has created a demand for peripherals, services and consumables – photographic printers, inks, memory cards, online services, and special papers to name just a few.

CeBIT: Philips’ Liquid Lens

Philips Research are demonstrating a new lens at CeBIT – interestingly, this breakthrough in optics might have one of the biggest impacts on digital lifestyles devices of any component at the show.

The new lens, built on Philips’ FluidFocus technology, is based on two fluids with different refractive indices – applying a tiny voltage across then alters the boundary between the fluids and bends the surface, thus changing the way light travels through them. The focal length can be changed very quickly, with response speeds of less than 10ms.

There are several factors that make this lens exciting for digital lifestyles devices – the lens is very small – 3mm in diameter, has a focal length of just 5cm to infinity, and can be mass produced cheaply. It is also very hard wearing: Philips have tested lenses to more than one million focussing operations with no loss of optical performance.

The lens is ideal for many applications – mobile phones, PDAs, digital cameras, sensors, home security, medical imaging … we’re sure you’ve already thought of some good ones too. Image quality in mobile phones and other small cameras should increase too – currently, many lenses are made of plastic with poor optical properties.

So, what’s the catch? Varioptic claim the Philips lens infringes one of their patents, and Philips are contesting their allegation.
