Audio codecs
Your product supports a range of audio codecs which provide compatibility with a wide range of Internet Radio stations. These also allow users to
stream music from their computers or to play directly from USB
fl
ash memory devices.
Note that for any given audio codec, there are many streaming protocols available, and thus even if an Internet Radio station uses a supported format,
this does not guarantee that every such station will work with the product. The radio stations database to which the product connects is checked for
compatibility so that most stations should be playable without problems. Similarly when streaming media from a computer, while a codec may be
supported, there can be many subtle variations in formats, tagging schemes and protocols (even within UPnP). In general your product will play the
supported formats with most common UPnP servers.
The following table summarises the maximum supported bit-rates for the various audio formats that are playable on your product. Higher rates may
be playable in some cases but performance of the product may be affected.
