WHERE CONVERGENCE GOES BOINK WHERE CONVERGENCE GOES BOINK Io Research P/L  2001  2001 OBSERVATIONS - DATACASTING & iTV DATACASTING is a mode *not* a quality. DATACASTING originates in the PC world. TV and PC each has its own acceptable display and GUI standards, location in the home and usage models.

WHERE CONVERGENCE GOES BOINK WHERE CONVERGENCE GOES BOINK Io Research P/L  2001  2001 CONCLUSIONS iTV should use small files broadcast synchronously with the TV content to which they relate, launched automatically by the operating system. Use of stream data will likely be limited. Large file distribution to a TV is *not* impossible - only difficult. It may happen, but the total system has not yet been developed.
