Mobile TV for the U.S.

Being early to digital TV meant the U.S. was late to mobile TV. But the waiting is soon to end.

9 min read

In June, the vast majority of analog television broadcasting in the United States ended, leaving digital the only game in town. But the digital television standard adopted in 1996, called ATSC (Advanced Television Systems Committee), left out one potential group of consumers: those who want to watch TV on the go—sitting on a train, perhaps, in a stadium or café, or in the back seat of a car on a long trip.

When broadcasters, manufacturers, and the Federal Communications Commission (FCC) settled on the technical standard for U.S. digital TV, they believed they needed the entire bandwidth available—6 megahertz per channel—to transmit razor-sharp high-definition pictures to people’s living rooms. They didn’t think they could shoehorn in other features—such as fixing the problem that causes digital pictures to break up once the receiver starts moving at more than a few kilometers per hour.

Array of devices on a chip

This analog electrochemical memory (ECRAM) array provides a prototype for artificial synapses in AI training.

IBM research

How far away could an artificial brain be? Perhaps a very long way off still, but a working analogue to the essential element of the brain’s networks, the synapse, appears closer at hand now.

That’s because a device that draws inspiration from batteries now appears surprisingly well suited to run artificial neural networks. Called electrochemical RAM (ECRAM), it is giving traditional transistor-based AI an unexpected run for its money—and is quickly moving toward the head of the pack in the race to develop the perfect artificial synapse. Researchers recently reported a string of advances at this week’s IEEE International Electron Device Meeting (IEDM 2022) and elsewhere, including ECRAM devices that use less energy, hold memory longer, and take up less space.
