Introduction:

The client is a network routers and switches manufacturer in UK, currently working on USB web cam hardware design architecture which is there proposed product which will be manufactured in-house, Client wanted us to develop a application which reads output from any USB web cam and will stream data (audio, video, text) over internet which could be viewed in browser or LAVT Admin (application developed to view remote streaming).

Business Challenge:

The task was to transform live video and audio over the internet. All together, there were three modules of the system, a server, a client administrator and client agent. Client agent is installed on a PC with a USB camera. Client administrator is loaded on the actual users system that is going to preview the camera output at remote location. The server facilitates IP addresses of both to each other to establish a peer-to-peer connection.

Futurism Solution:

All together, there are three modules in the system: LAVT Server, LAVT Agent, and LAVT Administrator.

LAVT Server facilitates IP addresses of both, LAVT administrator and LAVT agent, to each other to establish a peer-to-peer connection. It also keeps track of all the LAVT agents and LAVT administrator by pinging them continuously.

LAVT agent is installed on a PC with any USB camera. Whenever the computer starts, LAVT agent detects the online internet connection and connects to the LAVT server through sockets and transfers all its details to it (like IP address, Port, Camera Location). LAVT agent also opens another port for transferring the Audio-Video stream over the Internet. The LAVT agent creates Advanced Systems Formatted (ASF) stream using Windows Media Encoder and send it on a streaming port. This encoding is done using variable bit rate to improve the quality and performance of streaming.

LAVT administrator is loaded on the actual users system that is going to preview the camera output at remote location. When LAVT administrator connects with LAVT server, it gets recent information of all the online LAVT agents. When administrator selects any agent, it creates a peer to peer connection with that agent. LAVT administrator module then collects the Audio-Video stream from the LAVT agent streaming port and shows it using Windows Media Player controller. The Administrator can view n number of cameras at a time.

The application is based on a Win32 Platform SDK framework and uses WinSocks2 for asynchronous socket communication. It’s developed in VC++.

Features:

• • Web enabled for location transparency.
  
• • Distributed architecture, since it is based on DCOM Architecture.
  
• • Compatible with any USB web camera.
  
• • Remote zooming and panning capabilities (Web Cam must support this feature)
