Compression: Crash Course Computer Science

The video tutorial covers the basics of file compression, starting with the need for smaller file sizes for efficient storage and transmission. It explains lossless compression techniques like run-length encoding and dictionary-based methods, including Huffman coding. The tutorial also delves into lossy compression, focusing on perceptual coding for audio and images, and concludes with video compression techniques that utilize temporal redundancy.
