- MP3 compression Explain in your own words what is meant by sub-band coding in acoustics and what role it plays in MP3 compression.How much does encoding technique effectiveness vary? Which one is now depended on, and why?What is the term used to describe the situation where multiple frames arrive at the same location simultaneously, causing a distorted signal?
- How might you encode audio (or video) data in two packets so that if one packet is lost, then the resolution is simply reduced to what would be expected with half the bandwidth? Explain why this is much more difficult if a JPEG-type encoding is used.MP3 encoding Explain in your own words what masking effects in acoustics are and what function they play in MP3 compression.Why is URI encoding necessary, and how does it work?
-  There is redundancy that can occur in video that is sent over a network. Encoding techniques take advantage of two broad classes of redundancy. Name these two encoding techniques, and how each can be used for more efficient compression.2.- What is the advantage of using Gray code encoding in certain applications?Video compression techniques allow for the creation of several copies of a video with varying degrees of quality.
