Highfidelityreview.com is reporting that DVD-AR, recordable DVD-Audio, is on its way. This enables you to record, edit and replay a wide variety of audio content on writable discs. The main purpose of the format is to realise high-quality recording using Linear PCM and/or Packed PCM, together with 'long-time' recording using any one of six lossy CODECs.
In addition to audio contents, DVD-AR allows the user to store still pictures and text, just like DVD-Audio.
DVD-AR is design to support both high-fidelity recording using loss-less formats and 'long-time' recording using any one of six lossy compression schemes. Discs can be created using both loss-less and lossy compression, although users need to consider the compatibility of created discs amongst their target playback audience. Both loss-less options (PCM and Packed PCM) are compatible with all DVD-Audio players as the PCM and PPCM encoders and decoders are mandatory for all DVD-Audio and DVD-AR machines, but the same cannot be said for all the lossy alternatives, of which only Dolby Digital and DTS are currently in widespread use. |
The specifications do allow for discs to be created using a lossy compression scheme alone, PCM or PPCM is not required on the disc itself.
