Best Multimedia Search Engine

In the present century the pace of development is moving forward in leaps and bounds. The main effect can be seen in the media system. It has been proved and accepted by all that a presentation using a combination of audio and visual means has a longer lasting effect than a presentation which uses only one medium that is either audio or visual. The reason is, the human brain can register an image and store it in the memory for a longer time.

If it is only verbal information the brain uses the imaginative power to draw a picture as per the audio data so that the information may be stored in the memory box for a longer period. The Multimedia Search Engine has been introduced as most of the search contents are using multimedia technique while presenting their online information for the search engines.

What is Multimedia?

Multimedia as the word suggests means presenting any kind of information whose content has a combination of the written matter, verbal presentation through digital recording, interactivity, images which are static and animation. The information in the content is processed with the help of a device which may be an electronics device or a computer device. Before the development of the Multi media the content used to be presented using only static images and printed matter. So multimedia is more interactive than simple media.

Multimedia has two broad categories. The non linear in which the viewer is able to control the movement of the moving images and the linear activity in which control of the moving images is not possible. Multimedia technique is being used by nearly all the sectors like education, entertainment, commercial, engineering, medical etc. The written text, sound, static picture are incorporated in a single matter. So Multimedia Search Engine was introduced for selection of the matter for internet information sites.

How Multimedia Search Engine Functions?

The functioning of the Multimedia Search Engine is just like the functioning of the SEO that is the search engine optimization. The only difference is that the spider in the search engine categorizes the site as per the Keyword rich printed text whereas the Multimedia Search Engine spider can categorize and rank the audio presentation, visual presentation in the form of video, pictures or animation. The Multimedia Search Engine categorizes and ranks the site in top hierarchy position if the presentation is designed in accordance to the online media.

It means that the text should be designed in such a way that quick scanning can be done by the readers. To make the site Multimedia Search Engine friendly so that it can be easily selected and categorized, the site should have innovative design, navigation should be easy, downloading procedure should be fast and it should be updated frequently to maintain the novelty. Thus the Multimedia Search Engine procedure has changed the whole concept of search engine technique. Now searching for a site will not depend on the keyword but the search can be conducted through pictorial or audio presentation which will cat as the keyword to conduct the search for a particular site or information on the net.

MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a digital audio encoding format using a form of lossy data compression.

It is a common audio format for consumer audio storage, as well as a de facto standard encoding for the transfer and playback of music on digital audio players.

MP3 is an audio-specific format that was co-designed by several teams of engineers at Fraunhofer IIS in Erlangen, Germany, AT&T-Bell Labs in Murray Hill, NJ, USA, Thomson-Brandt, and CCETT. It was approved as an ISO/IEC standard in 1991.

MP3's use of a lossy compression algorithm is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio for most listeners, but is not considered high fidelity audio by audiophiles. An MP3 file that is created using the mid-range bitrate setting of 128 kbit/s will result in a file that is typically about 1/10th the size of the CD file created from the original audio source. An MP3 file can also be constructed at higher or lower bitrates, with higher or lower resulting quality. The compression works by reducing accuracy of certain parts of sound that are deemed beyond the auditory resolution ability of most people. This method is commonly referred to as Perceptual Coding. [1] It internally provides a representation of sound within a short term time/frequency analysis window, by using psychoacoustic models to discard or reduce precision of components less audible to human hearing, and recording the remaining information in an efficient manner. This is relatively similar to the principles used by JPEG, an image compression format.

When performing lossy audio encoding, such as creating an MP3 file, there is a trade-off between the amount of space used and the sound quality of the result. Typically, the creator is allowed to set a bit rate, which specifies how many kilobits the file may use per second of audio, for example, when ripping a compact disc to this format. The lower the bit rate used, the lower the audio quality will be, but the smaller the file size. Likewise, the higher the bit rate used, the higher the quality, and therefore, larger the resulting file will be.
