Embedded Linux: Voice & Data Streaming
Voice & Data Streaming, Remote Recording from Application on Embedded Linux
Client had small sized embedded device which runs on Debian Linux & captures voice/ data & looking for ability to host session which allows real time view of activity (voice + visual synchronized) from across the globe and easy to play it back for those who missed live action.
The Problem
Separately transmitted data & voice from device needed real-time synchronization at server. Support for multiple devices, streaming & recording at high speed adds complexity & challenge for performance.
The Solution
- Linux Kernel Programming based “Live CD” is the obvious option available for the technical departments. The proposed solution read as “Opt for network accessed medium that is of low memory, easy to access and upgrade and furthermore disposable, reusable and transferable without hassles of licensing”
- The Linux Live CD is customized and developed using the “Linux Live Scripts”, the technique used is UnionFS and the customized solution boots from any removable devices such as CD/DVD Drives, USB Drives etc…
- We work on LAMP configuration for development and the Linux Live CD provided us with the much need SDK that serve all its needs well
- The SDK configuration also includes Eclipse IDE with PHP Plug-in, Open Office, Apache, Subversion and is also integrated with the domain controller
- The hardware detection of peripherals such as network cards, video or audio and graphics cards are done automatically
Value Addition
- Developed customized web player for real time & play back of session
- Cross Platform server application written using native c library
Major Achievements
- 60% saving from projected cost while implementing custom streaming server
- Easy user management, device management, and real-time status helped reduce the time for maintenance and monitoring
- Achieved 98% accuracy in synchronization of Voice & Data Streaming
