What is M2TS?
A .m2ts file is a Sony high definition video file type. M2TS files are raw AVCHD
videos recorded using Sony's camcorders, such as the HDR-SR(xx)series models.
Panasonic, Canon and other brands of AVCHD camcorders also record in m2ts format.
Currently, m2ts files can be played using the Picture Motion Browser, which is
an application video player provided with Sony AVCHD camcorders.
M2ts files can also be played with ALLPlayer, Mplayer, Windows Media Player,
BSplayer, VLC and other media players if there is a codec for DVD playing installed.
The file type .m2ts is not always automatically associated with the player, so
it may be necessary to open it from the player.
M2ts files contain a transport stream BDAV MPEG-2. Each stream is its own file
and file names are of the form XXXXX.M2TS (where "XXXXX" is date and
time stamp of when the video clip was recorded).
The M2TS file format is one of the three mandatory supported codecs (MPEG-2,
H.264/MPEG-4 AVC, and SMPTE VC-1) used on Blu-ray discs.
M2TS files can also be played on Sony PlayStation 3s and Sony Bravia TVs supporting
playback of AVCHD.
What is AMR?
Adaptive Multi-Rate (AMR) is an audio data compression scheme optimized for speech
coding. AMR was adopted as the standard speech codec by 3GPP in October 1998 and
is now widely used in GSM and UMTS. It uses link adaptation to select from one
of eight different bit rates based on link conditions. AMR is also a file format
for storing spoken audio using the AMR codec. Many modern mobile telephone handsets
will allow you to store short recordings in the AMR format. There also exists
another storage format for AMR 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.
Key Features:
- Sampling frequency 8 kHz/13-bit (160 samples for 20 ms frames), filtered to
200-3400 Hz.
- The AMR codec uses eight source codecs with bit-rates of 12.2, 10.2, 7.95,
7.40, 6.70, 5.90, 5.15 and 4.75 kbit/s.
- Generates frame length of 95, 103, 118, 134, 148, 159, 204, or 244 bits for
bit rates 4.75, 5.15, 5.90, 6.70, 7.40, 7.95, 10.2, or 12.2 kbit/s, respectively
- AMR utilizes Discontinuous Transmission (DTX), with Voice Activity Detection
(VAD) and Comfort Noise Generation (CNG) to reduce bandwidth usage during silence
periods
- Algorithmic delay is 20 ms per frame. For bit-rates of 12.2, there is no 'algorithm'
look-ahead delay. For other rates, look-ahead delay is 5 ms. Note that there is
5 ms 'dummy' look-ahead delay, to allow seamless frame-wise mode switching with
the rest of rates.
- AMR is a hybrid speech coder which uses Algebraic Code Excited Linear Prediction
(ACELP)
- The complexity of the algorithm is rated at 5, using a relative scale where
G.711 is 1 and G.729a is 15.
- PSQM testing under ideal conditions yields Mean Opinion Scores of 4.14 for
AMR (12.2 kbit/s), compared to 4.45 for G.711 (u-law)
- PSQM testing under network stress yields Mean Opinion Scores of 3.79 for AMR
(12.2 kbit/s), compared to 4.13 for G.711 (u-law)
