Because frequency allocation plans differ between European and US counterparts, a separate European DOCSIS has been developed exclusively for European countries under the name 'EuroDOCSIS'. The main difference between the two standards is in the TV channel bandwidths. For example, European TV channels confirm to PAL TV standards while American ones confirm to NTSC standards. In comparison, the wider bandwidth of EuroDOCSIS is advantageous to Internet users because it has more bandwidth that can be allocated towards downstream data path.
Japan has developed its own version of DOCSIS that is further distinguished from either of the existing services in either Europe or the US.
