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

Quick identification of technology, project approach and best utilization of existing development library helped to built high performance application.

Application on Embedded Linux was designed utilizing separate server & client components to achieve desire business functionality.

Main server comprised of streaming server, queuing of data & web application manages availability of streaming sever & web interface for user management and monitoring the connected devices and clients
With streaming app development, the server application was now receiving the data from device/client, queuing data for respective client/device, mixing the audio data, sending it to device/client
Administration section allows registration & administration of application via secure authentication
With our expertise in live streaming app development – the streaming server also performed rapid switching between data storage, streaming and delivered a smooth experience to end-user
Voice Streaming app development which supports recording and playback
Web Server for rendering request handling & queuing
This is subset of a streaming server that stores streamed data and allows people to playback previously recorded session with live streaming app development When playback is requested it stream data hence improves performance on moderate bandwidth availability
Activex control designed to play from web browser for easy viewing of previously recorded sessions of real time session
Playback Web Client
Data streaming app development with streaming server

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
