Tablet PC's - No Longer a Commercial Failure

A tablet PC is a light weight slate shaped hand-held computer or a slim note book PC. The idea is to replace the traditional pen and notebook with a tablet PC and stylus or digital pen. Historically the tablet was used by the Egyptians to write on clay tablets with a writing stick. In the present day the clay tablet has been replaced with a screen and the writing stick with a stylus. The tablet PC may be considered the pen and notebook of the future. They typically weigh around 2-3 pounds and their main feature is portability. The idea of a tablet PC was floated by Alan Kay of Xerox but was a commercial failure until now, when the prices have fallen down and it is expected that the prices will fall in future. The first widely sold Tablet PC was Newton of Apple Computers.

The hardware consists of a slim touch screen, stylus, optional wireless keyboard and mouse. In this type of computers the data input is not through the traditional mouse and keyboard but through a stylus or a virtual keyboard on the screen. It also has the facility of data input through wireless keyboard and mouse. The stylus is used to write directly/tap on the screen or fingers are used to input data through the touch screen. There is a magnetic field over the screen which interacts with the stylus electronics, hence the user can rest his hands on the screen without distorting the image and only stylus movement affects the screen. They come in various sizes like 8.5 inch, 10 inch and 14 inch.

There are different types of tablet PCs like slates, convertibles and hybrids. Slates consist of just the screen and the stylus. If a slate is attached with a keyboard it is called a convertible. Typically the keyboard is attached with a single joint and it folds/opens onto the screen. The Hybrid has a detachable keyboard so that it can be used both as a slate or a convertible.

Tablet PCs come with resident softwares like handwriting recognition software, speech recognition software, shorthand entry software, virtual keyboard etc,.

There are various advantages like portability, users who are not comfortable with keyboards find stylus more friendly, they do not interrupt line of sight as they are kept on the table and are helpful in meetings and are handheld so can be used in giving presentation while standing up. The disadvantages of Tablet PCs have been cost till now but since the prices have fallen and are falling, hence is not a constraint anymore.

Various companies like Acer, Lenovo, Toshiba Fujitsu, HP, Gateway, Compaq, Motion, NEC etc are manufacturing Tablet PCs.

Are they future proof? Till recent years the Tablet PC was a commercial failure but with the advances in battery technology, handwriting recognition software, wireless internet access, larger memory, better screen resolution they are being accepted as commercially viable option. Many popular science fiction movies portray the use of Tablet PCs. Tablet PCs are bound to replace the notebook & pen and future books, magazines, newspapers.

Video Compression - H.264 and Surveillance Industry

H.264 or MPEG-4 Part 10 (Advanced Video Coding) is an industry standard for video compression, this is the process of converting digital video into a format that can achieve very high data compression. So far Motion JPEG and MPEG-4 part 2 are the compression standards that are widely used in surveillance industry. With the use of H.264 video compression codec, surveillance industry could see a drastic change in the way CCTV systems are used. With the use of H.264 video compression codec surveillance equipment could see itself taking a major leap in terms of usage of storage space, better image quality and transmission of video.

Video compression codec H.264 involves encoding and decoding processes. The video encoder performs the process of encoding and transforming the video to H.264 bit stream and in turn the decoder decodes the bit stream and delivers the original content. If you are interested in complete process of how H.264 works please visit the resources listed below. The whole process is very accurate and reduces storage space by more than 50% without compromising on the image quality when compared to Motion JPEG and MPEG-4 Part 2. It also delivers same quality if not better images per bit rate when compared to MotionJPEG/MPEG-4 Part 2.

By using the video encoders which support H.264, an analog system can be integrated into more efficient and powerful IP based video surveillance system. This enables the system to deliver better image quality with higher resolutions, frame rates and multiple streaming capabilities, decreased bandwidth and storage requirements. Video analytical applications can be used with the converted video increasing effective usage and management of large-scale video systems such as big shopping malls etc. The use of H.264 modeled systems will have a greater advantage in surveillance industry in the near future and will encourage the use of Megapixel cameras whose biggest challenges are requirement of large storage space and huge usage of network bandwidth.

Surveillance DVR Software

As you will soon discover that when buying a stand alone DVR most of them automatically come with DVR software loaded already on to them. However for those of you who are looking to set up and then run a PC based DVR surveillance system you will need to also install some DVR software as well. So what should one be looking for when it comes to surveillance DVR software?

Below we take a look at some of the features that you should be looking for when choosing the right kind of DVR software for your surveillance system.

Motion Detection Function

Today there are many different levels of motion detection function that different DVR software programs can offer you and which you should be considering. But at the very least you should look for software which has the capabilities to start the camera recording as soon as any kind of movement is detected. However if you want you can go for software which actually allows the camera to remain focused on the object in question and track it.

Control and Configuration of Cameras

Look for software which allows you to adjust the images on each camera that you have on an individual basis. Although some of the more basic software applications will allow the system to automatically adjust the images being shown based on a pre set configuration, but it is not as good as being able to actually manually adjust the cameras for yourself. Also look for those software programs that allow you to not only adjust the resolution of the images but allow you to use other camera functions such as zoom, tilt or pan features.

Maintenance of Alarm/Event Logs

The software you choose should provide you with the facility to be able to record and track all events that have caused the surveillance system to be triggered. By having this feature included in your software application it will provide you with a better understanding and see what has caused the event to occur.

Storing and Search Feature

If you can choose a surveillance DVR software program that provides you with the feature to not only store the video images being recorded but also allows you to carry out any searches through the use of a specified set of criteria's. Having this will actually make the process of being able to review the information that has been recorded and stored much easier to do and therefore make your surveillance system much more efficient.

Therefore by spending a little time carry out research in relation to the kind of surveillance DVR software application and keeping the above mentioned features in mind you should be able to find one that meets your own particular requirements. Plus it will also help to ensure that you get the maximum use out of your surveillance system as well.

4 Good Reasons to Get the Asus Eee PC 1005HA 10.1 Inch Netbook

1. Cutting-edge Specs: I wouldn't go as far as saying that the Asus Eee PC 1005HA netbook is the fastest computer in the market, but it does have almost all of the latest specifications for a netbook. First of all it is powered by the Intel Atom N280 processor (1.66Ghz), which is currently the fastest processor for a netbook. It comes with 1GB of RAM, 802.11n wi-fi capabilities, Bluetooth 2.1 connectivity and a 1.3MP webcam. If you are someone who only uses the computer for checking the mail, surf the web and perform simple word processing, the Asus Eee PC 1005HA netbook can adequately serve as your main computer.

2. Good Looks: Finally, Asus has decided to breakaway from its old chunky design (in older models). The new Asus Eee PC 1005HA netbook has a new sleek 'seashell' design. The thickest part is in the middle of the netbook, as it gradually becomes thinner towards the edges. Thanks to this new design revamp, this model is arguably one of the best looking models in the market. They come in black, blue, pink and white.

3. Good Keyboard Design: When netbooks were first launched, the cramped keyboard was one of the main reasons I stayed away from them. Fortunately, the keyboards on newer models are just getting better and better. The keyboard of the Asus Eee PC 1005HA netbook is currently one of the best in the market. It is 92% the size of a full keyboard, and most importantly has an almost full-sized right shift key. The keyboard feels very good to type on.

4. Amazing Battery Life: The average lifespan of regular laptops in the market is about 2 or 3 hours. Because of that, laptops aren't as portable as they can be. The battery on the Asus Eee PC 1005HA netbook can last up to 10.5 hours for the PU1X model and 8.5 hours for the VU1X model. We usually take the manufacturer's claims with a pinch of salt, but I did manage to squeeze about 8.5 hours out of my PU1X model and that is very impressive by any standards (I was watching videos, replying some email and downloading some movies).

Panasonic TC-P54V10 Vs Panasonic TC-P54G10

When it comes to creating quality Plasma HDTVs, Panasonic is an expert. Just take two of its best Plasma sets - the Panasonic TC-P54V10 and TC-P54G10, as examples, both of which have similar excellent features.

For one, both offer a THX certified display, which allows not just a simulation but a faithful recreation of the audio and visual ambience of a movie theatre so viewers won't have to fall in line to watch movies as they were intended to be seen. The THX mode also provides more accurate colors, particularly the primary ones, exhibits superior gamma performance and enhances picture quality overall, although videophiles might find the colors more realistic in the Custom Mode.

Another main feature of both the TC-P54V10 and TC-P54G10 is the Viera Cast, which is Panasonic's interactive suite. This allows viewers access to online updates from Bloomberg, such as news headlines and stock market updates, as well as local weather reports, YouTube videos and Picasa web albums. The best thing about Viera Cast is that it allows viewers to watch high quality videos - many of them HD - from Amazon Video on Demand, where a library of thousands of full movies and TV episodes are available via live streaming or for downloading without a subscription fee.

Of course, the TC-P54V10 and the TC-P54G10 wouldn't be among Panasonic's best Plasma sets if they didn't have impressive picture quality. In fact, this is the strong point of each, which is mainly due to their significantly inky black levels. This allows for sharper details and makes the rest of the colors appear more saturated. The colors on the TC-P54V10 look even richer, thanks to its Digital Cinema Color engine.

In fact, in spite of their similarities, the TC-P54V10 is superior in several other ways, like video processing, for example. Although both offer excellent motion resolution and can properly display 1080p sources, the TC-P54V10 has a 96Hz Mode, in which it can display 24p sources without any hitching problems. On the other hand, the TC-P54G10 only has a 48Hz mode, which can cause 24p content to flicker across the screen, especially in bright areas.

The TC-P54V10 is also superior in terms of design, even if its frame is thicker than that of the TC-P54G10. In fact, it appears very sleek with its seamless design where a sheet of glass covers the entire panel. It has a subtler silver accent, too, which forms an arc in the middle of the bottom frame. Both have invisible speakers, although the sound produced by the Viera TC-P54V10 is deeper and more authentic because of its BBE ViVA HD3D Sound technology.

The Panasonic TC-P54V10 has more picture controls, too, especially since it has a Pro Setting menu that videophiles are sure to like. It also has six picture modes, compared to the TC-P54G10 that has just five, one of which is called Studio Ref, which makes the screen resemble a studio monitor, to go with its five color temperature presets, five aspect ratio selections and a function that adjusts the screen brightness according to the ambient lighting.

The Panasonic TC-P54V10 also has the upper hand in connectivity with four HDMI inputs, two component video inputs, a PC input and an SD card slot, to name some. Still, its little brother, the TC-P54G10 is not so bad, offering just one less HDMI input. The biggest difference between the two, though, is their price and if you consider that the TC-P54G10 is just as good as the TC-P54V10 with a lower price tag, it isn't bad at all.

Why a Tablet PC May Be Right For You

Get ready for a new type of computer that is about to be as common as the laptop. In fact, you could think of it as the next evolutionary step of the laptop.

Before you replace your current portable computer, you may want to get yourself informed about this handy new machine that is known as the Tablet PC.

Of all the personal technology advances we've seen over the past five years, the Tablet PC has to rank among the most significant. For the Tablet PC is truly one of the most innovative and useful products that is just now starting to gain major traction. These machines, which are powered by a specially tweaked version of the Windows XP operating system, allow users to scribble notes on a screen with a pen-like stylus, turning handwriting or block printing into what's called digital ink.

Although Tablet PCs have been on the market for a few years now, much of the public has been unexposed to them. That's about to change. Tablet PCs are now showing up on TV commercials, in magazine and newspaper ads and being exuberantly talked about through word of mouth. Maybe it's time for you to consider one.

Some Tablets are slate models only. That means there is no keyboard, just the screen. You write on them like those old Etch-a-Sketches that kids used to play with. Others, are called convertibles. Flip the screen up and it looks and works like a notebook computer, with a keyboard, CD/DVD slot, track pad and the like. But swivel the screen around and down over the keyboard and it's a slate.

All of the big computer makers produce Tablet PC models: Dell, Gateway, Toshiba, Lenovo (IBM), Fujitsu and others. There are a couple of Tablet-only makers, too, like Motion Computing and Rugged Computers. Even Apple Computer with its fabled Macintosh line is rumored to be close to developing a Tablet version.

You can get a Tablet PC for arounf $1,800 with most of the features we all demand in portable computers like wo-fi Internet access and Bluetooth wireless. Some models have built-in CD.DVD drives (which adds to the weight factor), others include them as external devices.

Whatever you do, make sure you get enough memory to run all those cool applications. My recommendation is at least one GB, instead of the standard 512MB on most machines.

Over the past couple of years, Tablets have sold fairly well in what are known as vertical markets, among niche interest groups like students (great for note-taking and recording lectures), medical professionals (for keeping track of patient records) and salespeople (for forms and order-taking). Indeed, some schools are now giving Tablet PCs to their students, that's how great they are as educational tools.

But now that the momentum has built up, most observers are convinced the real market is much larger ... and largely untapped, if you'll excuse the pun.

The Tablet PC does everything a regular computer does. It has a complete Windows XP operating system and can run all of the normal programs and applications consumers are used to on their desktops and laptops. The big difference is that with a Tablet PC, you can also use that electronic stylus to run many programs, taking notes by hand or tapping on the individual letters of an on-screen keyboard representation to type.

Handwriting can be converted to type with just a tap of the stylus, though, obviously, the neater you write or print, the more accurate will be the conversion into type.

I've been a a tablet user for several years and, truthfully, I seldom convert handwritten notes on the Tablet. I don't need to. I can read my own notes just fine. And there's something satisfyingly personal about seeing my scribbes on a computer screen. It's sort of the ultimate in customization.

While a Tablet does everything a regular computer does, they have the added advantage of some special tablet-only software enhancements. I bought a $39 add-on to the Outlook program that lets me use digital ink to enter calendar, to-do, journal and contact info. And a $99 program called PlanPlus from Franklin Covey puts the equivalent of a Franklin Planner on my Tablet. I've fallen in love with this application.

Then there's Microsoft OneNote, which comes bundled on many of the Tablets sold today or can be purchased separately for $99. OneNote I believe, is the most amazingly useful application for any platform I have ever tried.

Besides the digital ink note-taking and organizational features, OneNote uses the built in microphone on the Tablet to record meetings, lectures, interviews, whatever you want. As you take notes of a presentation and hear something that's important, make a star or exclamation mark next to someone's words that you've jotted down, just as you do with pen and paper notes. Afterwards, as you review the notes, you can tap on the special mark you made to hear the actual recording of the subject as the presenter spoke the information.

No matter how much I use OneNote, it blows me away every time.

If you're thinking about a new laptop and if note-taking is a part of your life, a tablet should be at the top of your shopping list.

It's that handy.

Is a Tablet PC right for you?

Obviously, only you can answer that. But it's been my esperience as a longtime road warrior who has used all sorts of laptops, that the Tablet PC offers so many more features and so much more convenience than a standard laptop that I would never go back.

I bet you will feel the same.
