5.1 SYSTEM INTRODUCTION:

Our application starts with the Login function with requirement of User Id and

Password. Mainly contains two parts of the system.

1) Batch Data import: Import external data to the system for the information

regarding management data.

2) Video displaying.

1) Batch data import:

Batch data import is the first section of the project. In this section we are

storing data into database as normal function of the system. First section is the

interaction section with database that interacts with external data and user interface

for the system user. Batch import is the one primary level user interface that can

implement the more detail about the user and work to support the user to use second

section of the system. Registration of Farmer, Merchant and Area Admin ,addition of

crop, crop price, whether, seminar, news update,7/12,8/A certificate ,advance query

and its response system are remain in database system.

2) Send SMS and E-mail:

Master Admin send SMS to any farmer and merchant for any event about

farming so farmer easily know what is new happening in farmer field around them

and merchant also get confirmation for to buy crop from admin side.sms will be send

by connecting mobile to pc than select device for send SMS .This functionality also

at Area admin side remaining except SMS system

.

3) Get Certificate:

Farmer get certificate of 7/12 and 8/A from their account that certificate on

land that is useful for many place at bank, Toluca panchayat and more. Using this

system farmer does not have to go far for that.

4) Advance help system:

Farmer ask any question about land, crop agro, piyat ,irrigation problem,

subsidy, loan in farming and he get complete satisfactory solution for that without

any complexity and money.

5) Video streaming:

Following is the brief details of the changes /addition in Dspace to implement

the Video Streaming functionality. The Details provides list of java files , jar files

that were modified , class paths used to compile the sources and the details of the

flash plug-in used.

The video Streaming module for Dspace helps the user to view and even

download video software at the client machine.

We are using Quick time Full screen Video Player as our flv plug-in because it

is open source and freeware.

The plug-in also helps the user to view the video in full screen Mode.

The videos available were in analog format (Digicam,Betacam) Which were

converted to flv using super (an open Source software).

The Videos are as from their own desk without installing any converted into

Flash Video (flv) format because of the following Reason:

More than 80% Videos related websites are using flv as their format

already.

Commonly already available as plug-in in client so no new installation.

Supports advanced video codes like H264, Hence can deliver better

quality even at lower bitrates.

In the Existing system of Dspace , the user needs to download the

video but cannot see the video on the same pages.

The Video streaming modules for Dspace helps the user to view and

even download software at the client machine.

We are using Flv Flash player Full Screen Video Player as our flv

plug-in because it is open source and freeware.

The plug-in also helps the user to view the video in full screen mode.

In initial stage the video from VCD/DVDs are converted to flv using

FFMPEG library (open sources).
