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 AWB?
AMR-WB is codified as G.722.2, an ITU-T standard speech codec, formally known as Wideband coding of speech at around 16 kbit/s using Adaptive Multi-Rate Wideband (AMR-WB). G.722.2 AMR-WB is the same codec as the 3GPP AMR-WB. The corresponding 3GPP specifications are TS 26.190 for the speech codec and TS 26.194 for the Voice Activity Detector.
A common file extension for AMR-WB file format is .awb. There also exists another storage format for AMR-WB that is suitable for applications with more advanced demands on the storage format, like random access or synchronization with video. This format is the 3GPP-specified 3GP container format based on ISO base media file format. 3GP also allows use of AMR-WB bit streams for stereo sound.
The AMR-WB bitrates are 6.60, 8.85, 12.65, 14.25, 15.85, 18.25, 19.85, 23.05 and 23.85 kbps. Compared to narrowband speech codecs (like AMR) optimized for traditional telephone voice quality of 300-3400 Hz, the AMR-WB codec's wider bandwidth of 50-7000 Hz provides excellent speech quality.
