How video encoding works. Introduction to video compression and encoding definition. Motion compensation. What are codecs and frames types.  Implementation schematics of I-Frames, P-Frames and B-Frames.

This lesson gets into how video encoding really works. We’ll take you through an introduction to video compression and encoding definitions. We’ll then discuss motion compensation, what codecs are and frame types. Finally we’ll take you through some example Implementation schematics of I-Frames, P-Frames and B-Frames.

Lesson 1.6 Basic Video Coding Standards: H.261

Lesson 1.5 Basic Video Compression Techniques

Video Formats Supported by H.261. Frame Sequence. Intra-frame (I-frame) and Inter-frame (P-frame) Predictive Coding. Quantization in H.261. Video encoder and decoder. Macroblock, Frame/Picture Format. Encoding Formats. GOB Structure. What is bitrate.

This lesson will cover the video formats supported by H.261. We’ll then get into frame sequencing and Intra-frame (I-frame) and Inter-frame (P-frame) coding which describe how frames in a video are compressed and encoded to reduce the file size and maximize perceived quality by the user. Then we’ll cover Predictive Coding, where a motion vector estimates the amount of changing pixels in successive macroblocks which make up a video frame. We will also cover quantization in H.261, which averages out small differences in adjacent and successive blocks arranged together in Group of Block (GOB) Structures. Then we’ll provide some insight into what bitrate is in video. 

Distortion Measures: Mean Square Error, Peak-Signal-to-Noise ratio (PSNR). Rate-Distortion Theory. Quantization and Uniform Scalar Quantizer. Transform Coding and spatial frequency. Discrete Cosine Transform (DCT). Wavelet-Based Coding. 2D Haar Transform. 

In this lesson we’ll talk about lossy compression algorithms, and how it yields a much higher compression ratio than lossless compression with the goal of maximizing the compression ratio and minimizing distortion. Lossy compression algorithms make use of different distortion measures such as the Mean Square Error or the Peak-Signal-to-Noise-Ratio (PSNR) to describe the quality of the video signal. These measures provide a coarse reference to the perceived quality by the user. Compressing a video this way involves multiple steps to reduce the amount of transmitted data while maximizing the fidelity to the original signal.

Lesson 1.2 Lossless Compression Algorithms

Lesson 1.3 Lossy Compression Algorithms

The JPEG Standard. Observations for JPEG Image Compression. Block Diagram for JPEG Encoder. Main Steps in JPEG Image Compression. Color Space Transformation and Subsampling. DCT on Image Blocks and quantization.

This lesson discusses image compression standards, focusing on the JPEG (Joint Photographic Experts Group) standard of image compression, which has been the industry standard since 1992 and is still actively used and deployed worldwide today. We will be discussing the different steps in the JPEG image compression algorithm such as splitting the image up into blocks and averaging out the small color differences to take into account only the main transformations overtime.

Lesson 1.4 Image compression standards

Categories of Lossless Compression. Huffman and Arithmetic Coding. Coding trees, decoders and examples. Dictionary-based Coding. LZW Compression Algorithm. LZW Decompression Algorithm.

This lesson will cover lossless compression and different encoding and decoding algorithms such as Huffman coding and Arithmetic Coding. These compression algorithms encode an exact copy of the data which can be perfectly reconstructed at the decoding phase. We will go through an example of how each of these algorithms work by looking at a simple example of encoding and decoding with the word ‘HELLO’.

Graphics and Image Representation. 24-bit Color Images. Color Lookup Tables (LUTs). Popular File Formats: GIF, JPEG, PNG, TIFF, EXIF.

This lesson is about basic image formats. We will review some basic graphics and image representations, then we will move onto bit-greyscale images, 24-bit color images in 8-bit versions thereof.  Then finally, we will give an overview of selected image coding file formats including GIF, JPEG, PNG, TIFF, EXIF.

Lesson 1.1 Basic Image Formats

What is the Bitmovin Developer Network? What will this course cover? Introduction to the teacher. Introduction to the material. Literature and Acknowledgments.

This course is designed to give you a quick introduction to the Video Developer Network and the motivation behind creating it. The Bitmovin Developer Network was created to empower developers to learn about video streaming, to understand image and video compression fundamentals. We truly believe in open source and the importance of spreading this knowledge and information about video development to the world. The course will begin with the simple use of still image compression, progressing to live streaming as you embark on the path to becoming a fully fledged online video expert.
