I’m not sure if you caught this during the week, but I thought it would serve as a good discussion point on whether or not it is a Good display of Bitmap or Vector graphics.
What do you think?

GPU Vs CPU
As part of the multimedia course we take about the graphics card a lot. But what difference does a decent graphics card make?
Well a CPU can do one thing at a time, even multi core machine can only manage up to 8 things at a time. However, a GPU can mange hundreds of calculations at the same time. I wonder how we could demonstrate that?
Last Night’s Scholar Homework Session
The link for last night homework session is:
New 4k & 8k screens
OK so we are jumping the gun on this a little but I thought it merited a little post. I am writing this back in January (the day before your prelim) and I am guessing at where we will be today.
Screen resolutions for television have traditionally been described in terms of the vertical pixels, 576i, 720i, 720p, 1080p but the new standards are now describing them in the horizontal. So a 4K UHD (Ultra High Definition) screen has in the order of 4096 horizontal pixels this is twice the resolution of 1080p HDTV (High Definition TV).

Pulse Code Modulation
So I was reading the list for the top past British innovations when I came across PCM and the Universal Machine. You have 4 days left to vote for your favourite, there really was only one choice for me in the past section. I guess you will need to wait till tomorrow to find out.
Digitised sound data
We introduced this topic today and looked at how sound is digitised and the role of the ADC in the sound card.
Powerpoints for Tuesday’s revision
I thought I might share with you a powerpoint version of the files that will form the basis of Tuesday’s revision periods. To create these files I used the arrangement’s document. You can use these to create flash cards or just to jot down your thoughts in preparation for Tuesday.
On Tuesday the whole class are going to be given live on-line editing access to the original documents and each person will be given slides to work on. You will also be given another 2 slides to check once you have completed your slide. By the end of the double period we should have a completed and content checked presentation that we can use with the blog and by ourselves.
Multimedia – Graphics
Well we have finished the Graphics section of multimedia. There are a lot of posts on this topic from last year so search for them.
To revise this topic we will be creating a presentation using Google Drive.
