1. Media Streaming Middleware for Handheld Devices (MeSMi) Project Supervisors:GroupMembers: Mr.Samantha SenarathnePradeep Dadigama Mr.Harshana LiyanageAsanka Widanapathirana Jeevanthi Panawala

2. Overview  “Mesmi” is a device independent middleware for media streaming between handheld devices.

3. Literature Survey  Searched for facts in the area of “Media Streaming”. Read facts on… 1.Streaming servers  How streaming is done in QuickTime,Real Player,Windows Media Player etc  Other open source streaming servers 2.Streaming basics  Books : The Technology of Video & Audio Streaming by David Austerberry. : Scalable Continuous Media Streaming Systems Architecture,Design,Analysis and Implementation by Jack.Y.B.Lee 3.Capabilities of handheld devices  Met our project supervisors and had discussions

4. Requirements Gathering and Analysis  Had a discussion with the project coordinator of the company  Identified the boundary of the system  Realized the functional requirements of the system  Identified non-functional requirements such as the quality of media, delay, foot print etc.  Decided what components should be in the system  Documented the Requirement Specification

5. First steps in Prototyping  Identified 3 main areas in the prototype 1.Converting the output from the web cam into MPEG4. 2.Streaming server 3.Decoder

6. Converting the output of the web cam into MPEG 4  Searched facts about different codecs  Read about …  Encoding basics  MPEG standards  More on MPEG 4

7. Converting the output of the web cam into MPEG 4 Cont….  Target: Implementing a low power codec  Motivation  Most of the existing low power codecs have been implemented in hardware basis.  There is a need of a software implementation of a low power codec.  Parallel Tasks:  We are writing code for converting an image stream into MPEG 4.  Searching for existing low power coding algorithms.  Trying to optimize them for our purpose.
