In the twenty century multimedia entertainment is more and more proportion in the human life and internet is more covenient to communicate and easier to change information. Video and audio compression technology are promote rapidly to drive people enjoying multimedia contents by using internet. However, the main three software factory provide high price of multimedia streaming technology and they have each patents on their multimedia streaming technology. From MP3 encoding technology view, it is used efficient to compress music data and let it be in trade of data size and high quality. MP3 file format is much appropriate to apply using many kinds based on streaming music applications. The technique in my paper, first I analysis MP3 encoding and deconding algorithm. Then I apply it in transferring streaming music by using reliable TCP/IP communication protocol to make multi-user and multi-channel music-on-demand system. By using Java server side technology, I make a web-based manager and user interface system and finally make the implementation of linux-based MP3 music-on-demand system.

Ever had an experience of forgetting to do something very important on a place you just past?. Remembering, on arrival at your destination afterward, requires an action to return to the task location. This can be unproductive and perhaps result to frustration. The purpose of this thesis is to develop a “Location Task-To-Do manager” an android mobile application that will efficiently organizes task-to-do list and remind an individual to perform a task at a pre-defined location through notification and alert messages. The methods used includes,  investigation of pre-existing systems, requirement elicitation survey technique, three-tier architecture design pattern, iterative development life-cycle model, acceptance test plan and a sets of other technology such as  Java SDK, Android APIs, TCP/IP protocol, object oriented programing techniques and MySql relational database. The result showed that, installed “Location Task-To-Do manager” application on individual mobile devices/smartphones were capable of creating task, adding task, editing task, deleting task, sharing task and setting task location through its user friendly graphical interfaces. Users are able to receive notification to perform a task within a minimum distance of 1km to the exact task location.
