Very high degree of a filtration
Earlier on all school British computers schools installed the filter which completely blocks access to YouTube. Was considered, that on a site it is too much the videoclips containing frank scenes and scenes of violence. However teachers complained, that cannot use many useful educational materials which are available on YouTube. It is a question, in particular, of videorecordings of research experiments which are too dangerous for carrying out in a class with children, about scenes from classical statements of Shakespearean plays and about other informative materials.Bloxx Media Filter, besides a filtration of videoclips, cuts from them the user comments, and also automatically generated list of links on similar videos.
