Pick of the week;Schools television
Children's BBC takes us into the realm of virtual game shows with Sub Zero. Web video conferencing will link both the children and celebrities in a studio, with players in Internet cafes around the country.
Teams will have to undertake a number of techno-challenges involving computers and the Internet but viewers at home can join in too, even if they don't have a computer. Using the telephone number key pad they can direct a remote-controlled robot round the studio or try to crack codes to earn extra points for one of the teams. Sub Zero is, naturally, on the Internet already: www.bbc.co.ukcbbc Sub Zero. BBC2 Sundays, 11-11.25am.
