Some TVs Go Directly Online for Streaming Movies.

For more than a decade, tech and media companies have wrestled with how to deliver digitized movies directly over the Internet to consumers: how do you get the copy-protected files from the computer to the big screen in the living room?

The early answers didn't inspire many couch potatoes to get off the sofa. You could either plug a laptop computer into your TV set (assuming the computer and the television had the right connections) or buy a box, called a media extender, for your home theater that received streaming files from your computer. Media extenders proved obstreperous and confusing: some files wouldn't play on some extenders, the boxes were awkward to set up and movie downloads were painfully slow.

Since then, faster broadband speeds have become more common and companies have figured how to stream videos that start in seconds, inspiring consumer electronics companies to put Internet connections into TVs, Blu-ray disc players and other devices to tap into online-movie services from the likes of Netflix and Blockbuster. It's an end run around the limited video-on-demand offerings from cable companies and eliminates the need for a separate black box.

"This is huge," says Dan Schinasi, a marketing manager at Samsung Electronics America. "This is what we have been waiting for." Samsung is doubtless enthusiastic, introducing Internet connectivity on 23 different TVs, starting at $1,600 for a 40-inch LCD model and three Blu-ray players priced from $200 to $350. Indeed, the trend is that such Internet connections will rapidly become standard. According to research analysts at NPD, 12 percent of flat-panel sets sold in September in the United States had networking capabilities, up from less than 1 percent a year ago. There are now Internet-ready models from LG, Mitsubishi, Panasonic, Sharp, Sony and Vizio.

The Samsung TVs, for example, access online movie services like Amazon Video On Demand or Blockbuster On Demand using Yahoo's widgets, small icons that appear on the bottom of the screen and which also include popular Web services like Flickr, eBay and YouTube.

Blockbuster's service offers movie rentals from $2.99 to $3.99, with purchases costing $7.99 to $19.99. At the moment, Blockbuster's titles can appear in wide screen, but only in standard definition, rather than high definition. It took about 25 seconds to start up the Blockbuster service, which offered new titles like the Jack Black movie "Year One" for purchase at $19.99 and "Unmistaken Child" to rent at $3.99. When you choose a movie, the software does a quick check of your set's connection speed and then starts playing your selection in under 10 seconds (easily beating cable video-on-demand from Time Warner in my tests). And while the cineaste in me wanted to shun anything less than HD, the standard-definition version of "Watchmen" was just fine, with instant gratification easily trumping any qualms I had about less-than-perfect image details.

Amazon Video On Demand was comparable, although it appeared to have a larger library of choices. The company claims to have more than 50,000 titles, with at least 2,000 of those in high definition. "Away We Go" was available to rent in HD for $4.99 (a standard-definition rental was $3.99). HD rentals were sharper and crisper to my eye, although a free stream of an episode of "30 Rock" in HD looked softer than the original live HD broadcast.

Other sets also offer Yahoo widgets and streaming movies from the Web. Sony offers the Yahoo feature on some sets and plans to offer Netflix streaming movies by the end of the year. LG Electronics has models that include Yahoo widgets and already include the online-movie services Vudu and Netflix. The former has the largest offering of HD movies to rent or own online and comes the closest in terms of picture quality and sound to true HD (1080p for the techie crowd). Rentals in Vudu's HDX format have sharper picture details and better sound than other offerings, although I still find the downloads and streaming versions a little darker (and thus less crisp) than HD broadcasts.

Known primarily for its by-mail movie subscription business, Netflix has become a digital movie juggernaut by streaming movies to subscribers free of charge. The same $8.99 a month you pay for a by-mail subscription entitles you to watch as many of the company's 17,000 digitized titles as you want, as often as you want, whenever you want. Its HD offerings lack the visual clarity of Vudu's, but Netflix is a better value and is available on many different devices in the living room — the Xbox 360, PlayStation 3 consoles, a stand-alone box from Roku, and TiVo machines. So if the Netflix option appeals to you, you don't have to buy a new TV or Blu-ray player to get it.

But choice also means confusion: not all services are available on all devices. On some of its flat panels, Panasonic offers its own Internet services, which includes Amazon Video On Demand, but not Netflix or Blockbuster or Vudu. Samsung offers Blockbuster on its sets, but not Netflix. LG offers Netflix on its sets, but not Blockbuster. And even when they do offer the same branded service, not all the devices necessarily give you the same features.

Netflix subscribers who use the streaming option on the XBox 360, for example, will find they can add movies to their queue from the TV screen (and they have to pay $50 a year for Microsoft's Xbox Live Gold membership to do so). But if you want to change your streaming movie lineup on the LG or Sony sets, you'll have to go back to your computer.

Buyers will also find that some sets, like those from Panasonic, Samsung and Sony, require a wired Ethernet connection for Web access. (Vizio's Internet-ready sets, due out this month, will have built-in Wi-Fi.) Samsung dealers offer an optional Wi-Fi adapter (802.11n) for just $80, and there are high-speed adapters that just plug into an electrical outlet. I connected a set using Belkin's 200 Mbps $100 Powerline AV Starter Kit without entering any codes or doing anything other than plugging the adapters in.

But we're still a long way from being able to order any movie we want to watch whenever we want to watch it. Film studios are loathe to release what they perceive will be blockbuster DVDs in digital form, for example, until months after release, and there are many more held back by copyright issues and concerns about piracy. And even the movies you can rent digitally from Blockbuster or Amazon are often subject to the dreaded 24-hour window, which means if you don't finish watching on the same day you started viewing it, you'll have to pay an additional charge.

Still, the option of streaming a movie from anywhere — Netflix, Amazon or whoever — is a major leap forward. It frees viewers from the yoke of the one-store-only approach taken by cable companies and products like Apple TV. Ultimately, it's a liberating experience — if you think of never having to get off the couch again to pick a movie as liberating.

Life360 Protects Your Family & Property Via Web, Mobile, & More.
Written by Jolie O'Dell

Life360 is often described as an "OnStar for life," providing its users with tools to track and protect people and things through a variety of interfaces.


The company offers IRL services such as child identification paraphernalia, medical IDs, and credit and identity protection; but they also have a cool suite of features that revolve around Internet and mobile tracking of people, objects, and even pets. Their Android application for tracking and securely messaging people even netted them a seed round from Google

The concept for the company, which was founded in the wake of Hurricane Katrina, revolves around disaster preparedness and emergency messaging. Currently, the available features include an emergency messenger that uses email, web, SMS, and phone to get messages through to emergency contacts; a thorough, web-enabled ID service that gives first responders instant access to critical information; a service for cataloging and tracking valuable items via coded tags; and identity protection services.

The mobile tracking feature - which got the company a $300,000 investment from Google - allows users to locate family members using the web interface or the mobile application. Custom privacy settings allow users to find loved ones in an emergency, check their locations, see their statuses, and retrace their previous locations. While the company states this will not make family members feel stalked, we see this app as Cheaters fodder as well as a great way to keep track of the ones you care about most during times of crisis.

The Android app allows users to access all their Life360 services from their phones. Right now, Android devices are supported, with a BlackBerry app coming soon and an iPhone app stuck in App Store purgatory.


Another "coming soon" service we thought was cool - and also excellent Cheaters fodder - is a GPS-enabled tracking dongle that can be thrown in a bag, duct-taped to the underside of a car, tossed onto a pet's collar, stapled to a child - you name it.

Life360 founder Chris Hulls told us in an email that he hopes to roll out the hardware within the next six months. "There will be an additional fee, probably in the neighborhood of $100 for the device and $10 per month for each tracked person," he said.

Some other GPS- and mobile-enabled features Hulls plans to release within the next year are a Curfew 2.0 app, a check-in system for "distributed" families to touch base, and customized alerts for emergency notifications in a user's specific location

Servidores domésticos de streaming.


Servidores domésticos de streaming.

Con estas aplicaciones, el ordenador reproduce archivos multimedia en la televisión del salón sin la necesidad de tender cables

Los Servidores domésticos de streaming son programas que transmiten música o películas desde un ordenador a cualquier otro aparato vía Internet o red interna IP/WiFi

Hace menos de diez años, para ver un vídeo o televisión por satélite en otro televisor de la casa había que cablear. Hoy en día, sin embargo, cualquier contenido audiovisual se puede transmitir desde un ordenador por vía inalámbrica dentro de una red doméstica o a cualquier lugar del mundo, si se accede vía Internet. Esto sucede gracias a los programas que actúan como servidores de streaming y que conectan con otros PC o con cualquier dispositivo equipado de wifi, como los avanzados teléfonos móviles de última generación.

Este tipo de aplicaciones transmiten contenidos hacia las redes domésticas o hacia un lugar distinto por completo gracias a Internet. Funcionan como los servicios profesionales de streaming, pero en el ámbito doméstico. Toman un archivo descargado con anterioridad y lo envían al punto donde se demande. Esto permite usos interesantes como destinar un ordenador sólo para acceder a la red y a los programas P2P y transmitir los contenidos a otro dispositivo, ya sea un disco duro multimedia conectado a un televisor o un aparato de música.

En los viajes, son útiles para acceder a los contenidos almacenados en el disco duro, siempre que se disponga de conexión y el ordenador de origen permanezca encendido y conectado a Internet.

La velocidad de transmisión en una red local es bastante más rápida que en las conexiones de Internet habituales. Por cable, se alcanzan hasta 100 megabits por segundo en el tipo de conexión más habitual, Ethernet, o de 1.000 megabits por segundo con Gigabit Ethernet, la última mejora tecnológica. En el caso del wifi, la especificación más frecuente, la 802.11g, llega hasta 54 megabits por segundo, mientras que la recién instaurada 802.11n posibilita un caudal máximo teórico que alcanza los 600 megabits por segundo. Estas cifras suponen una transmisión fluida de cualquier contenido audiovisual.

Si fuera necesario, a menudo, estos programas convierten o comprimen el formato de emisión a uno con menor tasa de bits por segundo. Esta opción conviene cuando la conexión es inalámbrica y no se recibe la señal con fuerza, ya sea por la distancia o por las paredes, que la obstaculizan.

Algunos programas

Subsonic es un desarrollo que trabaja como servidor doméstico de streaming y se promueve desde el campo del software libre. Se centra en la emisión de audio (aunque también funciona con las televisiones que emiten a través de Internet) y puede enviar a varios aparatos a la vez formatos comprimidos como MP3, AAC, WMA u Ogg Vorbis, entre otros. Funciona mediante una página web que se carga en el navegador y que sirve para bucear en las canciones que el usuario archive en el disco duro. Se instala en Windows, Mac OS X y Linux. Además, prevé la emisión hacia cualquier dispositivo móvil capaz de leer el lenguaje Java. También se controla desde una PDA o desde un terminal celular.




Se integra con Last.fm, el popular servicio para descubrir nuevas canciones y artistas a partir de otros usuarios con gustos similares, y lee biografías de los grupos y músicos desde sitios como All Music o Wikipedia. La conexión entre los aparatos se puede cifrar y también es posible fijar tanto límites en la velocidad de envío como diferentes privilegios para cada usuario.

Orb transmite vídeo, música, imágenes y señal de televisión, si se tiene la tarjeta sintonizadora adecuada, o de la webcam. Esta última opción abre la puerta a aplicaciones para la videovigilancia. Se maneja a través de una página del sitio web de Orb, por lo que hay que registrarse con nombre de usuario y contraseña.

Así se facilita el acceso desde cualquier ordenador, desde las consolas de última generación o desde los teléfonos móviles. Para favorecer la compatibilidad, convierte los formatos de archivos al vuelo entre un dispositivo y otro, y se adapta a las características de cada uno de ellos. Para las pequeñas pantallas de los móviles, envía vídeo con una resolución menor, que garantiza la estabilidad de la transmisión. De igual manera funcionan SpiffCast, Jinzora o Ampache.




SqueezeBox Server es una aplicación de Logitech dedicada al audio. Aunque se diseñó para dar servicio a los aparatos inalámbricos de esta marca, su código es libre y apto para cualquier ordenador a través de un reproductor multimedia. Importa de modo automático las listas de canciones de iTunes, puede incorporar las emisoras de radio en Internet y soporta los formatos de audio más habituales en la Red. Otra de las grandes alternativas, gratuita y programada en software libre, corresponde al reproductor multimedia VLC, si bien es una aplicación más complicada para el usuario medio, con un manejo menos intuitivo.



Los Media Center, otra opción

Los programas "Media Center" se han diseñado para manejar todo tipo de contenidos audiovisuales y fotografías dentro de un ordenador, pero también contemplan el envío de los mismos a otros ordenadores y dispositivos. Microsoft ha diseñado un software denominado XP Media Center, una edición especial de este longevo sistema operativo. En Vista, se halla dentro del sistema operativo. Con estos programas se pueden transmitir contenidos a otros aparatos compatibles con el protocolo Universal Plug and Play (UPnP)

Media Portal, el Media Center más popular entre las alternativas de software libre para Windows, integra un servidor de streaming para disfrutar de los contenidos en otros dispositivos. En Linux, MythTv cumple la misma función y resulta interesante LinuxMCE porque trasciende de los contenidos audiovisuales para controlar a distancia las aplicaciones domóticas en el hogar, como luces, climatología o sistemas de seguridad. Se basa en Kubuntu, la versión de Ubuntu que utiliza KDE como entorno gráfico.

Innovation Spending Looks Recession-Resistant
By Steve Lohr

A look at patent activity and economic slumps back to 1925. Enlarge This Image

Companies may have chopped capital investment, marketing and payrolls during the steep recession, but new studies suggest that research and development spending and patent activity held up remarkably well.

In its annual survey of the 1,000 largest corporate spenders on research and development, released this week, Booz & Company reported that their R&D budgets rose 5.7 percent in 2008. The rate of increase was less than in 2007, when R&D spending rose 10 percent. Still, it was an increase. And the consulting firm's survey found that 70 percent of the companies plan to maintain or increase R&D outlays in 2009.

"The thing that surprised us was that R&D spending didn't actually drop," said Barry Jaruzelski, a Booz partner. "But innovation is a fundamental strategy for these companies to hold onto their markets and gain an edge on their competitors. So it's sort of an arms-race issue. They don't want to disarm, despite the short-term economics."

Spending patterns, to be sure, varied by industry. Nine of the top 10 R&D spenders in the auto industry cut back, battered by the swoon in car sales worldwide. But software and Internet companies, Booz said, generally regarded the recession as a time to bolster research efforts. Eight of the top 10 R&D spenders in the software and Internet sector, the study said, increased their spending.

Many companies, according to Mr. Jaruzelski, did consolidate their research efforts, focusing spending around fewer, larger projects.

How unusual is the resiliency of innovation activity in economic downturns? In fact, it seems to be more the pattern over the years rather than an exception.

I asked the intellectual property research unit of Thomson Reuters to look at patent activity and economic slumps, going back to 1925. Patent applications either continue apace during recessions or are a lagging indicator during lengthy downturns.

In the Depression, for example, patent applications rose 25 percent from 1929 to 1932, which turned out to be the worst year for the economy, and only fell afterward. And the Depression years yielded fundamental advances in technologies of the future like television, nylon, neoprene, photocopying and electric razors, according to the Thomson Reuters analysis.

A similar trend is true around later, far shorter recessions, when basic work on personal computing and later Internet-related technologies were done. During the last year, patent activity in the United States has continued to increase, with 505,596 applications filed in 2008. The current pace suggests a total count for 2009 of about 520,000 applications. Alternative energy, energy conservation, nanotechnology, and smartphone hardware and software are hot areas now.

"Innovation works on a different time scale than economic recessions," said Bob Stembridge, an analyst at Thomson Reuters.
