MTV to AAC software converts MTV to AAC. The software is an ALL-IN-ONE audio converter that supports more than 90 audio and video files.
MTV to AAC software supports batch conversion and is full compatible with Vista and Windows 7.
What is MTV?
The format operates by displaying a series of raw uncompressed rgb565/555 image frames while playing MP3 audio but as the files are of low resolution and frame rate, sizes are comparable to MPEG-1 or MPEG-2. (in a bytes-per-minute sense). Encoding and decoding are less processor-intensive than other contemporary formats, as in fact very little "encoding" is actually done.
The MTV format consists of a 512 byte file header, followed by alternating audio and image blocks. Audio frame data is not necessarily aligned on block boundaries and each one of them has from 1 to n subblocks of 512 bytes each with 'n' remaining constant through the entire file/stream. The first 12 bytes of each audio subblock is padding data and is always set to 0. Image data, on the other hand, is perfectly contained in each image data block, each one representing an entire frame.
During decoding of the video stream, the audio frames are passed to the MP3 hardware decoder, while the memory pointer of the display hardware is simply adjusted to the next raw image within the video stream. While this concept does not require additional * hardware for the decoding process, it leads to huge memory requirements as no compression is applied to the image frame data.
What is AAC?
AAC has been standardized by ISO and IEC, as part of the MPEG-2 & MPEG-4 specifications. The MPEG-2 standard contains several audio coding methods, including the MP3 coding scheme. AAC is able to include 48 full-bandwidth (up to 96 kHz) audio channels in one stream plus 15 low frequency enhancement (LFE, limited to 120 Hz) channels and up to 15 data streams. AAC is able to achieve indistinguishable audio quality at data rates of 320 kbit/s (64kbit/s/channel) for five channels. The quality is close to CD also at 96 kbit/s (48kbit/s/channel) for stereo.
AAC's best known use is as the default audio format of Apple's iPhone, iPod, iTunes, and the format used for all iTunes Store audio (with extensions for proprietary digital rights management).
AAC is also the standard audio format for Sony's PlayStation 3 and is supported by Sony's Playstation Portable, latest generation of Sony Walkman, Sony Ericsson Walkman Phone, Nintendo's Wii (with the Photo Channel 1.1 update installed for Wii consoles purchased before late 2007) and the MPEG-4 video standard. HE-AAC is part of digital radio standards like DAB+ and Digital Radio Mondiale.
