Last week, IBM announced a family of chips that it hopes will accelerate the transformation of TV sets into fully interactive, two-way information appliances. IBM says it is combining high-speed PowerPC processors and other television set-top box (STB) components onto a single "system-on-a-chip" that will give STB makers "significant benefits in system performance, price, and design." IBM claims that the chips will also help drive new capabilities for electronic program guides, Web browsing, and interactive applications such as home banking, e-commerce, and information retrieval.
