This is for using the MVD hardware video decoder(unknown whether MVD can do more than decoding). The New_3DS Internet Browser uses mvd:STD for video decoding.
See here for the supported hardware decoder video codecs. Going by strings in the browser, the hw decoder seems to also support MJPEG.
A maximum of 4 sessions can be opened at a time, for all of these services combined.
