VoIP or Voice over Internet Protocol is relatively a new addition to the cutting edge telecommunication industry. Using VoIP one can make a call over a broadband connection by installing certain VoIP hardware as well as VoIP software configuration.

The biggest benefit of using VoIP is its cost effectiveness against traditional phone lines. The VoIP services provider plays a bigger role in saving costs; therefore utmost caution should be taken before choosing a VoIP service provider. Here are some of the points worth pondering before choosing a VoIP service provider:

Calling charges: Using VoIP technology can save up to 60 per cent of your telephone bills. The market is buzzing with VoIP service providers who are coming up with attractive call charges to lure customers. Therefore shop around in the market and look for a calling plan which best serves your needs. If you make most of your calls, to one particular destination or one number, check whether you can get a discount.

Phone number: Some providers allow you to carry your existing phone number to the VoIP services while some providers give you a new number. It’s always sensible to check the functioning and utility of your VoIP system before switching your existing number. Also verify whether your calling plan has free emergency services.

Extra features: VoIP has some value added features like call waiting, call routing three way calling, teleconferencing, videoconferencing etc. These features are usually included in the rental cost of the service providers. Some service providers offer certain features at extra cost. Make sure that the calling plan is very clear in your mind before choosing the service provider.

Long distance calls: If you want to reach across the globe using VoIP, then compare long distances charges of various service providers before choosing one. Also look for plans which can give you discount for international calls.

Money back scheme: VoIP is a fairly new technology therefore most VoIP providers offer a money back guarantee or a free testing period. The period ranges from two weeks to four weeks.

These are some of the points you can think about while choosing your VoIP services provider. But the most important point is to analyse your needs and choose a service provider which best suits them.

DVD Authoring is the process of collecting various content assets such as video,
audio, photographs, subtitles, and menus, connecting them together and burning
them to a master dvd disc.

The assets themselves are generated in a variety of applications such as video
editing, post-production, image editing and subtitling. They are then compiled in a
DVD authoring application such as Ulead DVD Movie Factory on the PC or DVD
Studio Pro on the Mac. The process of authoring is very much like building a
website. The menu screen on a DVD is analgous to the homepage of a website in
that it contains links to all the content on the DVD.

Menu screens usually link to the main feature, chapters within the feature,
additional scenes not contained in the feature, photographic slideshows, and
additional audio content. The main menu screen can also contain links to sub-
menus, which helps avoid cluttering the main menu with too many options.

In addition to setting up menu selections on the main menu, the DVD authoring
application allows the producer to set-up additional features such as subtitles.
Within the authoring application, each item is given the metaphor of a container. A
container can hold any type of supported content and is linked to a menu selection,
either on the main menu or a sub-menu.

DVD authoring applications also usually support the creation of multi-angle content
(where viewers can decide to watch a different passage of video with the same
soundtrack and subtitles) and Dolby 5.1 Surround Sound

Using this method it is very easy for even a comparitive novice to create a fairly
sophisticated DVD disc with most of the features found on a commercial disc.
Indeed the biggest challenge for the prospective DVD author is the aesthetic design
itself. Getting all the bits to work properly is one thing, but making it look good and
intuitive to use is another.

Once the content of the disc has been laid out in the authoring application, it is then
previewed to make sure everything works properly. It is then ‘multiplexed’ (the
content is linked together) and the master disc can be burned.

It’s worth noting that the affordable DVD writers and authoring applications only
support writing to DVD for General media which doesn’t have the necessary lead-in
tracks required by mass duplicators. Therefore this type os solution is not really
suitable for producing DVDs which need to be mass-duplicated.
