With the evolution of consumer electronic products, everything became digital audio, telephone, video, photography, newspapers.etc. So, the question -as mentioned by Alain Bouffioux (2006)- is not if a selected product will become a digital one; the question is when this product going to be digital' And how' New products already combine the three domains consumer/computer/communication (e.g…

But, the challenge for this technology is how to reduce image and digital video data rates.
This concise report gives an overview on the main features of video compression and different techniques used in this technology. And due to the rapid changes in this technology, online resources were the best choice for the content of this report. The report starts with video compression definitions, the report justifies the need for video compression. Then, gives a quick overview of the main standards used in video compression and a comparison of techniques used in this technology followed by factors to choose from different techniques. And in order to realize the fact of video today the report listed some of the problems with digital video. Finally, the report gives a conclusion and presents some future directions for the video compression technology.
Jim Duber once said, "The best description of compression is the one that said "Compression" is like making orange juice concentrate. Fresh oranges go in one end and concentrate comes out the other. The concentrated orange juice takes up less space, is easier to distribute, and so forth. There are different brands and types of concentrate to meet the consumers' needs or desires. Likewise, video compression takes a large file and makes it smaller. The smaller files require less hard disk space, less memory to run, and less bandwidth to play over networks or the Internet. Many compression schemes exist and have their specific strengths and weaknesses.
According to Video/Imaging DesignLine "Video compression algorithms" ("codecs") manipulate video signals to dramatically reduce the storage and bandwidth required while maximizing perceived video quality. Understanding the operation of video codecs is essential for developers of embedded systems, processors, and tools targeting video applications. For example, understanding video codecs' processing and memory demands is key to processor selection and software optimization.
There are other definitions for video compression. For example, TechEncyclopedia refers to "Video Compression" as "encoding digital video to take up less storage space and transmission bandwidth.". And Encyclopedian mentioned that Video compression "deals with the compression of visual video data. Video compression is necessary for efficient coding of video data in video file formats and streaming video formats."
The majority of online computing dictionaries define video compression as "Compression of sequences of images. Video compression algorithms use the fact that there are usually only small changes from one "frame" to the next so they only need to encode the starting frame and a sequence of differences between frames. This is known as "inter-frame coding" or "3D coding".

Film editing involves the process of the manipulation and rearrangement of video shots to form a new work. Editing is usually viewed as a part of the process of video production, with other post-production parts including color correction, titling, sound mixing, and image manipulation, among others.
Compression in Media Introduction In the modern day phenomenon, media is believed to play an imperative part in our life and the overall society. The smooth run of important information is considered to be vital for the reason of contributing to the progress of the overall society as well as the communities.
Data Compression Algorithms.
From the many years, numerous data compression algorithms have been developed to deal with specific data compression problem. From the developed data compression algorithms, there does not exist a single compression algorithm that compress all data types efficiently.
According to the report an automobile is composed of various parts both seen and unseen. The complexities embedded within the structure require every part to be present so as to perform the function of the whole machine. One of the most vital parts in an automobile is the tires. Compression molded tires are significant parts of the automobile.
The compression can be lossless or lossy. Lossless compression lessens bits through identification and elimination of statistical redundancy. There is no information that is lost in the lossless compression. In contrary, lossy compression lessens bits through identification of marginally vital information and eliminates it.
Computers, the fruit of technological revolution, had been related to mere calculations, word processing, banking, and science until the time the World Wide Web was invented. Surprisingly, with the spread of the Internet and innovative software, the boundaries between technology and art started blurring.
Online music is the latest trend and is giving a stiff competition to the traditional and conventional multi media systems like audio cassettes, video cassettes, audio and video CD's. The hardware and software required for the GII has o be developed, produced, installed, operated and maintained.
The Comité Consultatif International Téléphonique et Télégraphique (CCITT) is an association that has specified the particular rules for the standard data compression. There are different methods intended for
It has a design staff of 4100 people spread across various centers around the world. Tacit knowledge acts as a big barrier leading to inimitability because it is really a very complex process to accumulate such talent
This can be derived from the structure of the soda can. From the graph, it is evident that the material used in the construction is not ductile as upon reaching the ultimate stress, it crumbles (Voland, 2003, p. 191).
