11. VIDEO COMPRESSION Video compression uses modern coding techniques to reduce redundancy in video data. Video takes up a lot of space. Uncompressed footage from a camcorder takes up about 17MB per second of video. Because it takes up so much space, video must be compressed before it is put on the web.
Video Compression Techniques: An Overview

The MPEG-4 compression methods are used for texture mapping of 2-D and 3-D meshes, compression of time-varying streams and algorithms for spatial, temporal and quality scalability, images and video. Scalability is required for video transmission over heterogeneous networks so that the receiver obtains a full resolution display.

Audio compression algorithms are implemented in computer software as audio codecs. Generic data Video compression compression algorithms work with audio data but the Video compression refers to reducing the quantity compression ratios are low (around 50-60% of original of data used to represent video images.

Audio and video compression. 1. Audio Compression. 2. Introduction Audio signal or analog signal uses PCM Digitization process which involves SAMPLING. Sampling rate > or = to : 2 (Highest frequency component). Band-limited Signal: When the BW of comm. Channel to be used is less than minimum sampling rate then signal needs to be bandlimited. Speech Signal: …

streams. The most important compression techniques in use today are JPEG for single pictures, H.263 for video, and MPEG for video and audio. Currently the digital video interface (DVI), Joint Photographic Experts Group (JPEG), and Motion Pictures Experts Group (MPEG) are the three compression techniques that are widely used. Many
What is Image Compression? - GeeksforGeeks

In the field of Image processing, the compression of images is an important step before we start the processing of larger images or videos. The compression of images is carried out by an encoder and output a compressed form of an image. In the processes of compression, the mathematical transforms play a vital role. A flow chart of the process of the compression …
