Digital Tv: the New Golden Age of Television
Apr 12th
On February 17, 2009, Americans will enter the age of digital television — ready or not.
On that date, all full-power broadcast television stations will begin broadcasting only in digital, improving sound and picture quality as well as allowing for stations to offer multiple programming choices, called multicasting.
The government-mandated change will free up needed frequencies for public safety and new wireless communication offerings.
What’s the difference between analog and digital?
Since television was invented, stations have broadcast analog signals, or continuously varying radio waves. The familiar “snow” or ghosting of images is one problem with this way of sending broadcast signals. Another issue is the limited bandwidth for an ever increasing number of television channels.
After the transition, broadcasts will be sent only via digital signals, which use a series of zeroes and ones to transmit data just as a computer does. The result is clearer, more reliable picture and sound as well as the opportunity for more programming options and interactive features.
Because of how a digital signal transmits information, it has more room for additional data. So now television stations that once broadcast on one channel, such as channel 3, can now broadcast on several segments of that channel, for example: 3-1, 3-2, 3-3, 3-4. Each channel could offer specialized programming for a particular audience.
HDTV is the highest level of digital television quality, but it is not the only one. SDTV, or standard definition television format, is the quality at which basic digital broadcasts will be provided. SDTV offers an enhancement over traditional analog broadcasts, but it is not as sharp as HDTV.
What do I need to do to be ready?
If you have an analog input television and currently receive your television service through cable or satellite, you will continue to receive your current stations without needing to purchase additional equipment. However, to receive the full, original quality digital signal, you may need to upgrade your set or get special equipment from your service provider. Simply check with your cable or satellite company for more details.
Note that if your service goes out due to weather or other circumstances, you will no longer be able to receive traditional television channels without a digital tuner or digital-to-analog converter box.
If you have an analog input television and receive your signal via an outside antenna or “rabbit ears,” then you will need to purchase a digital-to-analog converter box to be able to continue watch television. Your set will continue to work as before with gaming consoles, DVD players, VCRs and other similar systems.
The new converter boxes are expected to be available in early 2008 and run between and . From January 1, 2008 through March 31, 2009, all U.S. households are eligible for a government coupon program to offset of the cost for up to two boxes per household. A list of eligible boxes is available from the National Telecommunications and Information Administration, which manages the program.
Aside from buying a converter box or signing up for a cable or satellite service, you could also choose to buy a new digital-input ready television. After May 2007, all new televisions must be ready for receiving digital signals or be clearly marked that additional equipment will be needed.
These next generation television sets are the best way to experience all that digital television has to offer.
You deserve to get the most out of your services, whether it’s high-speed Internet, phone, cable, or HDTV. Digital Landing is here to help, making it easy to find out everything you need to know about digital services for your home.

French Television Digital Switchover
Mar 7th
Digital terrestrial television has been around in France since 2005, when the TNT (Télévision Numérique Terrestre) came into service.
TNT offers a minimum of 18 free television channels, including the main existing terrestrial French television channels. By subscription, it is also possible to receive many other channels, including Canal+.
TNT does not give you access to UK television stations, for which you will need to buy and install a satellite dish!
The TNT service is already available to most of the population, although many households have chosen not to take it.
From the beginning of 2010 the diffusion of the analogue service will gradually be replaced, region by region, to be switched off definitively by 30 November 2011.
The calendar of implementation by region is as follows:
1st Quarter 2010: Alsace, Basse-Normandie and Lorraine
2nd Quarter 2010: Pays-de-Loire, Champagne-Ardenne, Franche-Comté and Bretagne
3rd Quarter 2010: Poitou-Charentes
4th Quarter 2010: Bourgogne, Centre, Picardie and Nord
1st Quarter 2011: Haute-Normandie, Ile-de-France and Aquitaine
2nd Quarter 2011: Limousin, Côte-d’Azur, Corse and Auvergne
3rd Quarter 2011: Alpes and Rhône
4th Quarter 2011: Midi-Pyrénées, Languedoc-Roussillon and Provence
As a result you will be required to convert or upgrade your television equipment to receive digital signals, either through a new aerial, by satellite, a cable service or through internet broadband.
Those who receive their television service by cable or ADSL need take no action, as they will automatically receive the digital service.
Likewise, those who have a satellite installed to receive French digital television need take no action.
Those who have purchased a new television within the past year or so should also be able to automatically receive the new service, as all standard televisions will have been equipped with an internal receiver. Larger screens and those offering HD may not be equipped, so you need to check if it is ‘TNT Intégrée’.
By contrast, everyone else who receives French television through a terrestrial aerial will need to install a TNT decoder on their television.
If you have more than one television, then you will need a decoder for each one, unless it is already incorporated in the television.
In some cases, even though you have purchased a television equipped to receive TNT, you may also need to upgrade your terrestrial aerial and cable. You may only be able to find out if you need a replacement cable and aerial by first testing the system. Even if you get a reception, if the picture quality is only poor to average, then you will probably still need to change your aerial and cable.
The decoder is easily installed with a SCART plug and cable that will be supplied with it, which is simply inserted into the sockets in the television and the decoder.
The decoder boxes are widely available, either from an electrical shop, major supermarkets, or on the internet. Prices start from around €30. Prices are higher if you want to receive HD, or you wish to be able to view one programme and record another at the same time.
Financial assistance is available for the purchase of a decoder and/or a new aerial or satellite, subject to a test of resources. Eligible applicants are those who are currently exempt from payment of the television licence and living in zones d’ombre, where signal strength is weak.
You need to contact the centre d’appel on 0970 818 818.

Digital Tuners: A Must While Switching From Regular To Digital Television
Jan 13th
It is now an open secret that the shift has been triggered in people shifting from the regular analog telvisions to the digital televisions. In a few years to come there will be only the presence of digital television and no cables will ever exist!
The crazy thing about this new change to digital televisions is that everyone is pretty much being forced to eventually accept the change.

It is the digital terrestrial TV that is the latest craze as a lot of people are preferring it now. An upgrade for the digital television services will be required which can be quite difficult for some people that have problems getting a good signal in their area of town. This is the downside about digital terrestrial television; it is not certain to work in all areas, especially areas that do not have a large population in that particular region.
Another modification to the equipment of the digital television is the addition of the digital tuners. The tuners of the digital television are quite different from that of the analog television. There is a tuner present inside the normal televisions and the VCR. The way that digital television works will require you to not only have a new digital television, but you will also need to upgrade to a digital VCR as well for compatibility reasons. You will also need to find the right digital television service to subscribe too. You can also get more than one tuner and a video recording set from reputable companies. Due to the advancement in the recording technology one can see a particular program and yet record another program that they do not want to miss.
As you can see so far, there are some great benefits and more options with digital television. In case you are not happy about the switch after acceptance you will still feel that it was a lot better than your analog television. There will be no better way to enjoy watching television than on this even if one ahs to spend a little more in buying the new equipment. Another thing to take note of on the positive side is that you will receive a lot more channels because digital television has a low bandwidth.

The Advantages of Digital Printing
Jun 30th
The digital age has officially begun. With the coming of the 21st century, many changes have occurred and improvements in technology results in helping our lives continually being more efficient and comfortable. Businesses are being more efficient than ever. Things that used to take like days and even weeks to be done can now be ready in just a few minutes or even seconds.
One of the industries that are greatly affected by the coming of the digital age is the printing industry. Digital printing uses the newest technology available in the market today and helps you in acquiring quality printing materials at very affordable prices. Not only that, digital printing reduces the time it takes for your prints to be done as well as lessens the labor needs of your company.
There are many digital printing options that you can choose from. With these options, there are so many more advantages that you can attain:
VARIABLE DATA PRINTING
Direct mail campaigns can greatly be improved with the use of variable data printing. Variable data printing allows you to mass produce your custom prints thus making it easier for you to make that personal connection with your target market.
For example, those personalized brochures or postcards that you get from your mail that advertises or markets different products and services – they are probably created from digital methods. Upon inspection of the prints you would notice that your letter includes your name, location and other personal information. When you go to your neighbor, you will see the same thing. Direct mail letters have their personal information printed also.
Variable printing is responsible for this. Through variable printing, you can state which elements of your design remain static and which elements you want varied from print to print. As such, the design of your prints as well as the over all layout of your materials remain the same while the name, address and other information about the customer is variable.
In the past this type of printing is hard to do since offset printing does not alow for short run prints and in more geared towards producing large amounts of copies of a single print. However, through today’s technology variable printing has become a viable option.
EASY WORKFLOW
The workflow of digital printers is also so much easier as compared to the workflow of offset printers. When printing your materials through the digital process, you will not need to go through the different mechanical procedures such as film stripping and color separation. Also, plate production is no longer an issue since the digital process uses direct to printer technology that allows you readily print your materials once they are uploaded to your printer’s computer.
PRINT ON DEMAND
The most useful feature of printing through the digital process is that you can print your materials on demand. You can specify how your prints will be done and when you want them finished. You can also specify the number of copies that you want and are no longer limited to ordering bulk orders in order to be cost effective.

Try These Tips for Successful Digital Photo Printing
Jun 30th
Digital photo printing is an arena all its own in the world of computers, scanners, and printers. Gone are the days when to print something, all you had to do was push a button or click the mouse. People had very little say in how the printed materials quality turned out. Things have come a long way since then, and photo printing leads the way. There are many things that people can do these days to control how a picture that is printed turns out.
Tons of software and different hardware are available to accomplish hundreds of fun tasks with photos. If you are interested in improving your skill at printing high quality digital photos, here are some tips to keep in mind and get you started.
Digital Photo Printing: Paper and dpi
One thing to consider with digital photo printing is the paper you are using. Any picture can be printed on standard printer paper, but the quality is extremely poor, especially looking close up. You can buy the more expensive, good quality photo paper, which will help tremendously, but dont forget to change the type of paper in your printer settings from standard to photo. These settings can be found in the Printer Setup menu. The photos wont be in top shape, even with good photo paper, if the printer thinks it is printing on the standard stuff.
Another good idea when it comes to digital photo printing is to really familiarize yourself with the concept of dpi. The dpi, or dots per inch, of a printed picture will determine the quality of a printed photo when it is enlarged. The higher the dpi, the better the quality will remain for larger size printouts. We have all seen that digital cameras are many times classified according to how many megapixels they operate with.
To figure out how many pixels you will need to produce a high quality printout, multiply the dpi by the picture size. For instance, an 8X10 photo with a dpi of 150 would need 8*150X10*150 pixels, or 1200X1500 pixels, which most 2 megapixel cameras can handle with fair to good quality.
There are many people who are not interested in messing with the pixels, the printers, the papers, the ink, the dpi, and so on. For those who would rather not deal with it all, there are many stores, online and otherwise, that you can take your digital memory storage device to who will take care of the digital photo printing for you. These days, just about anywhere that develops 35mm film will be able to print out your digital photos for you as well. Rest assured, these professionals know all of the numbers and settings that will give you top notch printouts that youll love for years.

3 Tips For Making Digital Signage More Effective
Jun 30th
A chief concern among businesses which are considering the use of digital signage is that such a network will be ineffective. Indeed, much of what we’re witnessing in the industry suggests that many businesses don’t understand the potency of the technology nor how to harness it. This is likely due to digital signage being a new and innovative technology. Though many advertisers are experiencing success, standards of usage haven’t been firmly established.
For example, newspaper or television advertising follows proven models of successful. The strategies that are deployed in those media are based upon what has proven effective in the past. Digital signage is new and therefore lacks a benchmark approach. That being said, traditional advertising yields helpful clues regarding what works.
Why The Customer Matters
As advertising has evolved, so too has the consumer’s receptivity to marketing. No longer is the typical consumer content to be bombarded with a litany of marketing messages. Today, they focus on what is relevant to them and quickly discard – or ignore – the rest. Whether you’re deploying a digital signage network in a movie theater, casino, shopping mall, or a small chain of kiosks, the messages you broadcast across the system must address the concerns of the customer in a compelling manner. The experience must be engaging for the customer. Below, you’ll find 3 tips for making your digital signage efforts more effective by focusing on the customer.
Tip #1: Encourage Participation
It’s easy said than done. But, it is possible to create a broadcast that encourages your audience to interact with your message. This can be as simple as leading them through a tree of choices. Or, you can design a complex series of messages that builds your audience’s expectations about your products while allowing them to creatively select their own path through your inventory. There are many ways to encourage participation. You need to identify your customer’s concerns and then engage them.
Tip #2: Use The Data
The digital signage networks that are available today can yield valuable data regarding customer choices. This is one of the reasons why encouraging their participation is critical. When customers interact with your displays and proactively make selections, they do so based upon their interests and the effectiveness of your message and presentation. By reviewing customers’ choices, you can identify parts of your message that are ineffective. That provides the opportunity to modify or eliminate them.
Tip #3: Make The Experience Personal
Whether the experience that a customer has while interacting with a digital screen will be positive or negative is largely dependent upon how personal that experience is. For example, assume that a customer is looking through an inventory of shoes. Each selection will further identify that customer’s concerns. This can provide a framework around which you can tailor your message to address specific concerns based upon gender, age, vocation and other factors. Each selection builds upon the element of personalization. And the more personal your digital signage broadcast is, the more engaged the customer will feel.
Making Digital Signage Effective
Most fundamental principles of marketing address an audience’s interests, concerns and passions. Digital signage is no different. To leverage its effectiveness, you need to engage your customers with messages that are compelling to them. By reviewing the data that your network yields, you can create an experience for your customer that feels personal and encourages them to interact.

Ricoh R8 Digital Camera Review
Jun 30th
The Ricoh R8 is a 10 megapixel digital camera. It has a 7.1x wide angle lens. The design is different to all the more standard digital cameras out there, with a stylish, retro look.
Why Buy the Ricoh R8?
The R8 is a step up from the more simple point and shoot cameras. This is true when it comes to build quality and picture quality. Among its features are image stabilisation, a 2.7 inch LCD screen (I found easy to see even in sunny conditions) and a face recognition setting for portraits. It also has an option to produce square photos.
Image Quality Ricoh R8 test shots
Outdoor 1 (Medium Zoom)
This is a shot with a lot of contrast. There are the bright areas of the boats and the wooden slats underneath the roof of the building. In addition there are plenty of shady areas under the trees. The R8 manages to bring out an impressive level of detail, especially in the lighter areas where it outperforms many cameras. This helps to make the detail on the boats stand out.
Outdoor 2 (No Zoom)
In this photo sharpness stands up well and the scene also shows vivid colours. Many digital cameras tend to lose sharpness when the lens is fully zoomed out, but this camera copes with the scene better than most cameras manage.
Outdoor 3 (Maximum Zoom)
As in the first test shot the light colours on the boats are handled well. There is a very small amount of purple fringing, but in my opinion the R8 handles this very well when you take into account the longer than standard zoom lens. Focusing is again above average.
Outdoor 4 (Building)
The R8 does very well in this test. The brickwork on the building is sharply focused. Even in the shady areas the camera does a good job. When it comes to focusing the R8 is up there with the best compact digital cameras.
Outdoor Portrait
Looking at this photo I can see that the colours are very strong. That is fair enough if you like strong colours, but they are a bit too powerful for my own taste. Otherwise the level of detail the R8 manages to pick out is impressive.
Indoor Portrait with Flash
The sharpness of this photo is very good indeed and the R8 picks out the eyes very well. The skin tones are overdone. They give areas of the cheeks and nose a vivid pink that does not exist. This can also be seen in the lips.
Indoor Portrait without Flash
When I looked at the indoor shot with flash I felt the skin tone problem may have been down to the light produced by the flash. Even with the flash turned off the skin tones are harsh. Otherwise the photo is o.k., but could do with a touch of extra brightness.
Colours
The colours produced by the R8 have a different feel to them than those produced by most other digital cameras I have tested. They are certainly vivid and have plenty of brightness too. In some cases the strength of colour is too much for me.
Macro
This is another example of a sharply focused shot with plenty of definition. The R8 is well above average when it comes to close up shots.
ISO 400 and ISO 1600
At ISO 400 you should still be able to take a decent shot in brighter conditions, but darker areas will attract noise. Picture quality has broken down even more than usual at ISO 1600.
Overall
I found focusing and definition to be some way above average. The R8 also handled contrasting scenes well. Colours are very strong and I would prefer to see these toned down in a number of my test shots.
Shutter Lag
Shutter lag times were 0.34 seconds for a single photo and 8.98 seconds for five photos. With flash on times increased to 0.51 seconds for a single shot and 14.4 seconds for five shots. All of these times are standard times.
It took 2.36 seconds to turn the R8 on and take a picture. This is in line with the majority of digital cameras I have tested recently.
You can compare this camera to other models by taking a look at the Shutter Lag Comparison Table.
Style: Ricoh have given the R8 a bit of an old fashioned look. This helps it to stand out from the crowd. It is available in black, silver and in a two tone version.
Dimensions: 102 x 58.3 x 26.1mm
Weight: 168g
Batteries: Ricoh estimates you should be able to get around 270 pictures before the lithium ion battery needs to be recharged. Both a battery and charger are supplied with the R8.
Memory cards: 24mb of storage have been built into the R8. This is enough for around 7 photos. The camera is also compatible with SD and SDHC cards.
Ease of use rating: Good. There are one or two extra features to get used to when compared to a more basic point and shoot model. If you are planning to use the R8 as a fully automatic camera then you should be up and running in no time.
Points I like:
LCD screen clarity – novel design – sharpness
Where it could improve:
Skin tones in some portrait shots
Alternatives
There are not that many digital cameras that strike me as a clear alternative to the R8. Other 10 megapixel cameras with a wide angle lens include: Samsung NV24HD.
Verdict:
I like the Ricoh R8. It is certainly worth considering alongside some of the more widely recognised brands such as Canon, Sony and Panasonic. Aside from some issues with colour the R8 takes a decent photo in most situations.
