Week Eleven: 07/12/2012

This week in the lecture we did some tutorial questions as there are no more lectures to do.

The questions where are follows:

Q1. A true colour image
640x512 pixels
RAW uncompressed
What is the minimum storage space required?

Ans. Total = 640x512x3
=~ 0.9mb

Q2. If a video player played images of the above type at 30fps
What is the bitrate?

Ans. 30x0.9mb/s
30x8x0.9mb/s (the 8 is due to the bitrate)
=235mb/s

Q3. Video(including audio) is transmitted
1080x1024
120fps
3bytes per pixel
3D
AUDIO 24 bit sample
96kHz sample rate
7 channel surroundsound
Lasts 90mins
If no compression, what is the minimum file size?

Ans. 262069862400 bytes

These might be useful for revision for the test next week.

LAB
In the lab I went through all my blogs to check they were up-to-date and put in some links and picture that I had previously forgot to put in.
I also uploaded the video from last week to YouTube, I was having a problem with it at home.
I feel that my blogs have enough information to help me pass my test next week.

AT HOME 
Between now and next week i will look at the example tests on moodle and revise all the Powerpoint and my blog to ensure I pass the test next week.
