Digitization is the process of converting information into a digital format. Text and images can be digitized similarly: a scanner captures an image (which may be an image of text) and converts it to an image file, such as a bitmap . An optical character recognition (OCR ) program analyzes a text image for light and dark areas in order to identify each alphabetic letter or numeric digit, and converts each character into an ASCII code.
Audio and video digitization uses one of many analog-to-digital conversion processes in which a continuously variable ( analog ) signal is changed, without altering its essential content, into a multi-level (digital) signal. The process of sampling measures the amplitude (signal strength) of an analog waveform at evenly spaced time markers and represents the samples as numerical values for input as digital data. Digitizing information makes it easier to preserve, access, and share. For example, an original historical document may only be accessible to people who visit its physical location, but if the document content is digitized, it can be made available to people worldwide. There is a growing trend towards digitization of historically and culturally significant data.
LTPL provides the following digitizing services:
E- Publishing - The publication of books, periodicals, bibliographic databases, and other information resources in digital format, on compact disk or online via the Internet, or provided in a file format compatible with handheld electronic devices, with or without a print counterpart is known as E-Publishing.
Audio books – It is a recording of an oral reading of a book. Here you may listen to the story and need not read it.
Multilingual E-books/ Translation – E books can be translated in any language required and then converted into any format of E-book.
Layout/designing – The book designing, formatting, text placing, image selection and insertion are all done.
Data acquisition – Data collected and analyzed from various sources to provide the desired output.
Proofreading/editing – The conversion work done by another vendor are checked, analyzed and also edited for a quality output.
Editorial and graphic design – The images required in the digital publishing to suit the device are designed accordingly.
Interactive E book – These are books on digital format with sounds and which will interact with the reader.
Animated E-books – These books show different animations to make the material more interesting and user friendly.
Post digitization the data is finally used in the mentioned output mediums:
It is very important to understand why people digitize the data. Many a time existing digitized data is also reorganized in other formats to be able to be more devices friendly.
Storage – Organizations like to store data these days in the digital format so that space, cost of storage, aging and acts of man or God do not damage the data.
Future reference – Many people retain their accounting data and most organizations also retain their client data for future reference.
Promotion – It becomes easier to promote books, magazines, newsletters to digital medium. It is also easier to advertise in audio visual format for which digitization is necessary.
Convenience – To save cost of paper and to carry the data digitally is easier like presentations.
Security – In order to prevent data from being lost from war or act of God, data is now digitized for security and normally kept on cloud (server).
Enforced Law – It is now mandatory in many countries to provide digitized data under the right to information Act.
Service – Online search of past records is why digitization is necessary.
