Uni­ver­sal Plug and Play (UPNP) is a se­ries of pro­to­cols that al­low devices eas­ily to dis­cover and com­mu­ni­cate with each other over a net­work to share in­for­ma­tion.


DLNA fo­cuses on me­dia for­mats and man­age­ment, al­low­ing con­tent (video, au­dio, pic­tures, etc) to be shared across devices, with the user able to man­age said files. Most DLNA tagged devices are UPNP ca­pa­ble too.


Cd-qual­ity refers to the res­o­lu­tion of an au­dio CD, which is 16-bit/44.1khz. Cd-qual­ity should not be con­fused with high res­o­lu­tion au­dio.

High res­o­lu­tion

High-res­o­lu­tion au­dio has a higher sam­pling fre­quency and bit rate than Cd-qual­ity au­dio. Hi-res files tend to use a range of sam­pling rates, the most com­mon be­ing 96khz and 192khz at 24-bit.


NAS – Net­work At­tached Stor­age – is an in­tel­li­gent stor­age de­vice. Con­tent stored on a NAS can be ac­cessed through a me­dia streamer via a net­work.
