Overview

AAC is the descendant of the MP3 format. It provides better sound quality using a similar bit rate as of MP3. Besides this, it uses lossy data compression but it has high standards of audio quality than of MP3. We can find this format on a number of platforms and Apple's iTunes is one such example that uses it as default audio format. Size of its file is much smaller which is approximately one-tenth of MP3 file. It also neglects the redundant information that is not even processed by the human ear and is often not noticed. Although, this format was introduced as MPEG-2 Part-7, yet, standardization was done by ISO/IEC as a part of the MPEG-2 and MPEG-4 families. It is also termed as MPEG-2 NBC (Non- Backward Compatible) because it is incompatible with MPEG-1 audio formats i.e. MP1, MP2, MP3.

Technical description

Modified discrete cosine transform(MDCT) algorithm is used by AAC which ensures that it provides high compression efficiency. MPEG-2 PART-7 has three default profiles namely Low Complexity (LC), Main Profile (Main) and Scalable Sample Rate (SSR). These profiles come with Perceptual Noise Substitution which enhances coding efficiency and provides excellent audio quality. Furthermore, it uses Auditory Masking to ignore the surplus information. This codec has come up with advanced features which are not available in the predecessor. These include additional sample rates ranging from 8 to 96 kHz, 48 Channels, better efficiency with a simpler filter bank, higher coding efficiency for stationary signals and higher coding accuracy for transient signals.

Overview

It is a multimedia container file format which is used over the internet to provide digital video content to the users. Digital video content includes TV shows or series, movies; etc. Adobe Flash Player 6 and new versions provide support to it. To play flash video from Personal Computer and online websites we need an FLV player. Although, Apple iOS does not support Flash, yet, with the help of additional software, one can play flash videos. Also, it is a common platform for various websites that allows video streaming such as YouTube, Yahoo! Video, Metacafe, Hulu; etc . With the help of screen capturing and other recording programs, screen recording is possible for flash videos. Furthermore, it also supports a screen share or screen cast.

Technical description

FLV files mostly have video bitstreams which are one of the variants of H.263 Standard and it is named as Sorenson park(FourCC FLV1). The SWF files and this extension uses the identical way to encode data. There are two variants available for screen casting. First one is lossy as it reduces colour depth or bit depth (number of bits used to indicate the colour of one pixel) and compresses the data. The second type is only compatible with Flash Player 8 and the newer versions. Both these aforesaid kinds are based on bitmap tile. Uncompressed Audio or ADPCM format audio is also supported by it. This format has header and packets in its video structure. A standard header includes signature, version, flags and header size.
