What is M2T?
Conceived as an affordable high definition format for digital camcorders, HDV quickly caught on with many amateur and professional videographers due to its low cost, portability and image quality acceptable for many professional productions.
HDV video and audio are encoded in digital form, using lossy compression. Video is encoded with the MPEG-2 codec at a rate of either 19 or 25 Mbit/s (depending on the frame-size), using 8-bit chroma and luma samples with 4:2:0 chroma subsampling. Stereo audio is encoded with the MPEG-1 Layer 2 codec, at 384 kbit/s. The compressed audio and video are multiplexed into a MPEG transport stream, which is typically captured onto magnetic tape, but which can also be stored in a computer file.
Because the primary recording media ¡ª tape ¡ª is transported with constant linear speed, the rate control for both the audio and video compression are locked to a constant bitrate. At the bitrates and frame-sizes (1280x720, 1440x1080) at which HDV operates, the video compression may introduce visible artifacts artifacts, such as blockiness, blurring, ringing. Artifacts are most visible in playback of scenes with lots of fine detail, rapid movement or other complex activity like flashing lights. These scenes would demand the bitrate to exceed the fixed 25Mbit/sec that HDV allocates for the video bitstream, and hence, suffer visible degradation. In contrast to the video, HDV audio bitrate is comparatively generous. At the coded bitrate of 384kbit/s, MPEG-1 Layer 2 audio is regarded as perceptually lossless.
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.
