- Knowledge and understanding surrounding bandwidth and latency.
Learning Outcomes |

- To be able to compare and contrast the delivery and playback requirements between
- Complete download and play

- To be able to compare and contrast the delivery and playback requirements between the following multimedia delivery approaches:
- Complete the download and then play
|
| |
-
- Streaming of stored media (e.g. a movie or song)
- Live media (e.g. live sporting event or radio broadcast)
- Real-time interactive media stream (e.g. Video or telephone call)
- Issues associated with streaming of data
- lost or late data
- playing back at the proper rate
|
|
<

- Controlling the stream (i.e. starting stopping positioning)
- Requirements of the stream, i.e how timestamps and sequence numbers are used to ensure proper playback

- Controlling the stream (i.e. starting, stopping, positioning)
- Playback requirements of the stream, i.e how timestamps and sequence numbers are used to ensure proper playback
|

- Handling lost or out of order data

- (Content distribution and scaling?? Or is this something that is more appropriate for a separate topic or even the next course.)

| | Lesson Plan
Lecture 1
- Pre class Activities
- In Class Activities
|
|
<
< | |
>
> |
-
- Invention exercise - design a streaming protocol to handle playback of a movie, then a live event, then for the ambitious add the control of the stream
- Invention exercise - design a header for a real time transport protocol that runs on top of UDP (i.e. invent RTP) Maybe this is really the same as the previous activity or and extension of it.

Lecture 2 |
|
<
< |
-
- Invention exercise - design a streaming protocol to handle playback
|
| | |
|
>
> |
-
- Invention activity - design a protocol to control the playback of a realtime stream. (i.e. invent RTSP) We would probably want to list several things that we would expect the students to address in this invention activity, or maybe that is part of the activity.
- Invention activity with respect to device location. (i.e. something like SIP)

- Multimedia streaming assignment from Kurose and Ross
 The multimedia chapter of Kurose and Ross (Chapter 7 in 4th edition) has a programming assignment that uses RTP and RTSP. The text directs one to a website for the full assignment and supporting materials but I wasn't able to find them. However, the link at the start of this bullet has them. (In cast the above website disappears, I have "archived" its contents in the file RTP.tar.gz.
