The mpeg-1 file format extension is standardized in ISO/IEC 11172. It was extended from the H.261 and JPEG file formats and is capable of scaling down VHS video at a ratio of 26:1 and CD audio at a ratio of 6:1. The format allows for transcoding of video and associated audio to a maximum bitrate of 1.5 Mbit/second. interlaced video is supported in the second iteration of the mpeg format, mpeg-2. Video encoding is achieved using the compression standard H.262. The newer format also has added support for newer audio encoding techniques.
AMR format encodes narrow band signals between 200 and 3400 hertz at a maximum bitrate of 12.2 kilobits per second. The format employs the ACELP ' Algebraic code-excited linear prediction algorithm, a proprietary speech encoding method created by the VoiceAge Corporation.
