Abstract:
Presently, there are many popular media formats such as Windows Media
format, Real Media format and QuickTime Media format. To play the media
streams supported by different media formats in a browser, we need to
install a plugin such as Windows Media player, Real Time player or QuickTime
player. There are two problems of this approach. First, it's not convenient
for users since they need to install different media plugins which
constantly expire. Second, the security implementations of different player
plugin software are different. There is no unified mechanism to ensure the
security of downloading and playing media streams. The goal of this master's
project is to develop a Java media applet, which have the ability to deal
with multiple media stream formats, to directly play media streams delivered
by the RTSP server in a secure way. The Java media applet will work with
server side software which implements Secure Sockets Layer (SSL) protocol to
ensure the security.
CS297 Results
- Wrote a simple Java program to experiment with functionalities of the
JMF API. Since Java is the target language of the CS298 project, this
deliverable helped me get to know about its ability to play media
streams.
- Wrote a server-side program which implements part of RTSP. This
deliverable helped me get familiar with RTSP.
- Wrote an application that is on top of JSSE (Java Secure Socket
Extension) [SUN03] API. This Deliverable let me experiment with the
functionalities that provided by the JSSE and get ready to build a SSL
applet and server in the final project.
Proposed Schedule
Week 1-4:
(Aug 25 - Sep 19) | Write the RTSP server. |
Week 5-9:
(Sep 20 - Oct 24) | Write the media applet functioning as
a RTSP media player. |
Week 10-12:
(Oct 25 Nov 14) | Write CS298 report. |
Week 13-14:
(Nov 15 - 28) | Give a CS298 draft to the committee.
Prepare final presentation. |
Week 15
(Nov 29 - Dec 5) | Finalize the report. |
Week 16:
(Dec 6 -12) | Oral defense. |
Key Deliverables:
- Software
- An SSL-enabled RTSP server that can work with my SSL applet.
- An SSL-enabled applet that implements RTSP. This applet is not only a
mini media player that supports AVI format as well as is flexible to allow
for other formats in the future.
- Report
- Background information and motivation behind the study of this writing
project.
- Description of the architecture of the applet.
- Description of experiments using my applet and server.
Innovations and Challenges
- Provide the ability to play media streams in any Java-enabled browser
without using a plugin.
- Provide a channel to ensure the security of downloading and playing
media streams.
- Develop a Java media player without using available Java API such as
JMF. For the client machine, we can not assume that any API library is
preinstalled.
- Optimize and minimize the size of the media applet. The size of the
applet is crucial since it is directly related to the download time at a
given bandwidth.
