I has indeed been difficult to work in my office, especially now that I have run out of valid excuses to delay working. Now there's no more pretension, I just don't want to do it. Basically the reason is because I'm not exactly sure what I'm doing, it's difficult to justify anything as worth my time.
That said, my reading of the MPEG book took a downward turn when it devoted an entire chapter to the discrete cosine transform. I have a BS in math, but I don't recall ever learning this. So I looked it up and tried to reconcile it with what the book is doing. Things don't perfectly match up, but I'm not entirely sure if I need to understand the tiny details of how it works.
But I really do want to understand, because understanding will help me be able to explain exactly why the discrete cosine transform is so valuable in video encoding and decoding. So I think today, I'll write a program that does DCT's. I'd rather just do some problems by hand, but that appears to be a little bit more complicated because the equations are slightly more complex than a high school textbook.
Besides, doing some coding will make me feel like I'm being productive. Even when it might turn out to be a complete waste of time.
