| The Span of Multimedia spreads over image,video and audio. The algorithm developers avoids the duplicate part of the
information and it compressed at the encoder side and decompress at the decoder side and recreate the original information. I am posting this for a brief study of the nature of Multimedia Algorithms specially in image and video. I want to know what are the properties which is applicable through algorithms in Image for compression? I heard the technique of motion compensation and prediction between refference frame and other frames. This property is applicable by efficient algorithms in video. Which is the counterpart for this in image? | ||||

| I recommend Googling about JPEG, MPEG, transcoding and MP3.
There's lots of info on the internet about those subjects. | ||||

Good read, but I found something cuckoo in there: See chart at http://www.cs.cf.ac.uk/Dave/Multimedia/node266.html#SECTION04293300000000000000
Ummmmm .... no. 352x240 is below all consumer tape formats. VHS, 8mm and Betamax all have more detail to be resolved into a digital pixel palette. 352x480 is required to adequately capture all available information. Film production at 1080? Try 2K or 4K. :!: | ||||

| I think its true that on average most sites covering technical data should be further referenced for accuracy ... thanks lordsmurf for picking up the technical error :) | ||||

| Seven years out of date even in 2001. |
