While sharing this on the wireless router is a great idea, it works on only one PC or device at a time. So the whole point of router sharing is meaningless. Also software for the Tuner is very poorly designed. Not easy to understand or navigate. Cannot recommend unless user has great software savvy. When I use a lan connection, there is no lag but when I tried to use a 'G' USB receiver.... the quality of video drops terribly..... so ensure that you have a 'n' receiver and 'n' router for best results.
Quality of HD view is very good. Further, the user may select Audio Channel (main or sub). So you can watch movies or NHK news etc in English (if original transmission is in Bilingual mode)
I located an APP for Android phone (but you have to have to search deep using the software maker's name) but this does not work on Android 4 (Sharp 104SH). As I cannot check with another phone.... please beware.
It supposedly works with iPhone...I have not verified.
To sum it up, totally useless to share on the network when only one user can view....
