Recently, he has turned his attention to the critical question of how to play television programmes on computer screens, a conundrum computer giants are spending billions of pounds solving. His deal yesterday with Domark, the equally precocious British video games designer, supports his claim that he has cracked the codes that will allow any computer owner to play television programmes or receive video messages without worrying about compatibility or buying expensive new equipment.
If he is right, his codes could become an integral part of the booming CD-Rom and video-conferencing industries. The shares rose 10 per cent to 335p yesterday. For Mr Streater, an obsessive worker who owns about 20 per cent of Eidos, the problem remains of how to spend his riches.
