Abstract
The present invention uses multiple broadcast television channels to distribute high volume of data to a client device from a server. Multiple analog channels are broadcast, at least one of which contains video/audio programs and control data inserted into the analog signal's VBI; and at least one separate channel contains a digital data stream which is modulated onto an analog channel and associated with channels containing those video/audio programs. STBs designed to implement this invention are equipped with at least two tuners in order to tune to two of those channels simultaneously. One tuner is used to tune to the video/audio channel, and extract the control data in the VBI. The second tuner is used to tune to the channels containing the data itself.
