FYP Project LYU0301:Secure and Reliable PDA-Based Communication System

Secure and Reliable PDA-Based Communication System

Abstract Design and develop a PDA-based

communication system for a group of workforce (e.g. Police)

The communication content should be secured. The system can be executed over 72 hrs (at

least) without crash. Fault tolerant measures on both the client and

server sides. All the information should still be consistent

after failure. Unauthorized users cannot access the content

Symbian-based Mobile Tour Guide System

Abstract Develop an interactive tour guide system

using the Symbian OS (e.g. Nokia 3650…) The system should equips multimedia

presentation capabilities. Making use of messaging systems: MMS

and SMS. Making use of the camera function of

modern mobile phone devices Location sensitive elements can be added

• Background– Videoconference is becoming popular– Participants wish to keep videoconference

archives for the later reference– Normal video and audio files are neither

searchable nor helpful to recall their contents– Indexing of videoconference archives has not

been investigated till now

LYU0302: PVCAISLYU0302: PVCAIS

• Objective: develop an experimental system with the following architecture.

LYU0302: PVCAISLYU0302: PVCAIS

• Project tasks1. Study the mechanism and media format of a

videoconferencing client to receive data.

LYU0302: PVCAISLYU0302: PVCAIS

• Project tasks2. Select a group of algorithms to implement

the multimedia-indexing functions.3. Integrate these functions to generate an

XML index file for each videoconference.4. Create and manage the file system of

indexed archives.

• Project tasks5. Implement a GUI of PVCAIS to provide

the searching and browsing functions of indexed videoconference archives.
