With the growing proliferation of broadband Internet in every household, it is a natural phenomenon for services that have traditionally been delivered via analog means to be alternatively delivered via Internet Protocol (IP). One of these services is the broadcast of television programs via broadband Internet instead of radio waves. This is called Broadband Internet TV.The major advantages of broadband Internet TV are:Broadcasters can reach a wider audience without having to worry about the additional cost needed, since the viewer pays for the broadband access. This translates to a bigger opportunity to generate more income from advertising.The viewer need not be at home to be able to watch his favorite TV shows since all he will need is Internet access. Again, because the Internet is so pervasive, it now becomes possible to be anywhere in the world and still be up-to-date with the latest news, sitcoms and other TV shows that you would normally watch at home. This brings rise to the opportunity for broadcasters (assuming that their business model does not rely mostly on advertising revenues) to charge subscriptions for remote access to their shows. Using encryption, data for shows. The viewer can be selective as to the shows he/she wants or allows his children to watch. Filters can be applied to block or limit access to certain shows.There are, of course, disadvantages to broadband Internet TV. For example, to be able to access broadband Internet TV, of course, assumes that there you have access to broadband Internet with speeds of at least 256kbps. This is a relatively slower speed than that which was required a few years ago when 512kbps was the minimum broadband speed was needed. Better compression technology makes streaming video at lower speeds possible. Nevertheless, broadband access is still a requirement.Another disadvantage of broadband Internet TV is that it requires that you either have a computer with the appropriate decoding software, or a set-top box with decoding software. The latter is needed if you want to use your television set as the display medium.Also the broadband Internet TV output resolution is currently inferior to that of radio broadcast technology. This is because higher resolution requires more file storage space that translates to more bandwidth to get a real-time streaming video experience. Also, the bigger the image, the finer the resolution needs to be so that it does not break up during display. Again, this translates to bigger file sizes and bigger bandwidth requirements. "Broadband Internet TV" is offered in two modes: Free and Subscription Based. The Free mode is the akin to the conventional free-to-air television programming, where all you need to have is a television set configured to the broadcast system in your area (e.g., NTSC, PAL/SECAM, etc.), a television antenna to capture the broadcast, and electricity. Subscription mode is similar to the model of cable TV, where a monthly fee is paid for a set of channels, with extra charges levied for premium channels on a pay-per-view or monthly basis.

If you have two or more computers at home that are wired together to share resources, then you have a home computer network. Anyone who uses a computer, which encompasses almost everyone, should be aware of the need to back up important data. There are options available for network data storage that may not be available for the single computer. The first step in deciding how to conform your network "data storage" is to determine the type of backup you should use. Usually a backup is done by making a copy of all of the existing files, like a snapshot in time, and then adding backups of the changes as they occur. The other decision to make is the location of where to keep the backups.Here, There and EverywhereIf you don’t store very much on your home computer network, you may be able to manage your home network data storage project on DVD’s. With a small amount of information needing backup, you might just use rewritable DVD’s and make a full copy of chosen files as needed. If there is one or more computers on your network that is primarily used for internet use, email, web surfing and games, then the need for data backup is limited. The benefit of this type of home network data storage is that you have control over whether or not to back up a file and you choose how often to do the backups. The downside that many people don’t update their backups often enough and frequently the discs become lost or damaged due to inadequate storage practices. The next step up is to create a server to store backup files for all of the computers on the network. A server is simply a hard drive, and software is available for small home networks. There are also network-attached storage (NAS) devices which act as a dedicated backup server. The benefit here is that the software can be set to automatically perform backup procedures at regular intervals. The drawback is that the backups are in the same place as the computers, and may fall victim to whatever type of disaster makes it necessary to use the backups. Finally, there are remote services that will automatically use the Internet for home network data storage. Once signed up, the user is charged according to the amount of storage is needed. The benefit is that data is stored remotely and the updates are automatic. Drawbacks are that large amounts of data can be costly and that it’s only as reliable as the company. The decision on the type of home network data storage to use is based on the needs and resources of the network users.
Get ready for Office 2007, the most sweeping update to Microsofts popular suite of productivity applications.An extensive re-education awaits those who will upgrade to the new Office 2007. Its truly a redesign. The menu bar and navigation buttons for Word, Excel and PowerPoint, for example, look completely different.But before buying, Id suggest you do think about whether you're willing to spend the time learning new ways of doing things. Office 2007 has a great many new features and controls.Theres something else thats very different: Microsoft uses a different format to save files with Office 2007 that, without a special viewer that will have to be downloaded, makes them unreadable with earlier versions. When saving a document with Office 2007, you have the option of saving as a previous version which makes them compatible with earlier versions but Im betting this change alone is going to cause massive amounts of confusion among the early adapters.That said, the beta of Office 2007 that Ive been testing for the past couple of weeks is faster, more powerful and lots more intuitive and interconnected to other programs and files. Once you figure it out.There are lots of subtle new features, too, like built-in blogging functionality and something called the ribbon that replaces the traditional toolbar and gives greater control over each programs various functions.Office 2007 is the biggest change Microsoft has ever made to the interconnected suite of software tools so many of us depend upon.So big, its going to take a learning curve to master.Buying Office 2007 also promises to be confusing. There will be no fewer than eight versions to choose from, all aimed at different markets ranging from home and student users, to small businesses, midsized companies and corporate conglomerates. Depending on what software you have bundled into Office, the prices will range from $147 to $679.
The Nokia N73 is geared more towards a photographer on the go than someone needing to network and stay in touch. This mobile phone is definitely a smart phone with an exceptional quality of camera included. The 3.2 MP phone has a Carl Zeiss lens and a 20x zoom, a second lens for self portraits, and photo editing software in case you need to make touchups. The display of the phone acts as the viewfinder in landscape mode, but operation resembled a natural camera thanks to external buttons. The phone can capture video clips as well. A removable cover protects the main lens. Other features include a mini USB port and 42 MB of internal memory, as well as an expansion slot for Micro SD. This mobile phone is Bluetooth 2.0 ready and you can not only snap shots, but listen to your favorite hits from the music player wirelessly. These qualities make the N73 a great choice for those who enjoy a good multimedia experience. Also, the high-quality camera will appeal to many people who enjoy taking pictures on the go or traveling extensively and who don't enjoy carrying too much gear.One disadvantage of the N73 is that you will need the ear buds included with the phone to act as antennae to pick up FM tuning signals. Other downfalls are the N73 mobile phone not having external options for music controls such as pausing, stopping, or skipping songs. One would think that needing external controls besides volume would be a natural one, but it seems that developers felt being able to play music loudly or quietly was enough for consumers.There is, however, an equalizer to fine-tune the sound of music. Real Player is integrated on the N73, for those who like that particular software.You can use the N73 as a modem for your PC, and the phone is also user-friendly for internet browsing and emailing, thanks to Symbian OS 9.1. QuickOffice is loaded for document viewing and covers a wide range of file formats. The N73 comes in two color combinations: Silver and plum, and white and red. Neither are particularly sleek combinations compared to other phones, but the colors do look nice nonetheless. This mobile phone is referred to as candy bar, measuring 4.3 x 1.9 x 0.7 and weighing 4.1 ounces.Despite the major drawbacks of cramped keys and the need for external controls for music and entertainment enjoyment, the N73 is a good smart phone with plenty of solid features for multimedia.
