The project in five facts.
Challenge, approach and results.
The purpose of this diploma thesis is to research and present some of the most popular methods and file formats that are most commonly used today for compressing text, images, audio and video for use on the web. Mass use of the internet requires special processing of this content, otherwise we can quickly suffer from slow transfers, software incompatibility and various space constraints. Data compression can effectively save on the size of digital records, which would otherwise be too large for normal use on the web. This brings into play various compression methods, compression algorithms and file formats, whose inappropriate use can have a markedly negative impact on the content being compressed.
Problem
The purpose of this diploma thesis is to research and present some of the most popular methods and file formats that are most commonly used today for compressing text, images, audio and video for use on the web. Mass use of the internet requires special processing of this content, otherwise we can quickly suffer from slow transfers, software incompatibility and various space constraints. Data compression can effectively save on the size of digital records, which would otherwise be too large for normal use on the web.
This is done by attempting to remove as much redundant data as possible from the record.
Solution and Method
This brings into play various compression methods, compression algorithms and file formats, whose inappropriate use can have a markedly negative impact on the content being compressed. Compression can take place in lossless or lossy mode, where the former is more suitable for archiving and preserving the original quality of the record, whilst the latter is more sensible for mass transfer over the web and efficient space saving. However, due to the rapid development of information technologies, the question arises here regarding the overall efficiency of this type of data compression, as this technology also has its weaknesses.
Weaknesses such as compression and decompression time, software and hardware requirements, various ** incompatibilities, distortions** in records and limitations imposed by the formats used can quickly cause inconvenience for the average web user. Thus, the aim of this diploma thesis is to test and investigate how efficient this type of data compression actually is, what the limitations of such file formats are and where the boundary lies between efficient and inefficient.
