Digital TV Shows on Cellphones in Japan

USA Today reports that Japan's 90 million cellphone users already play video games, download songs, exchange messages, read news, trade stocks, store digital photos and surf the Web on their tiny screens. Now, they're doing something less tech-savvy and more mundane: watching TV.

Free digital TV broadcasts for portable devices equipped with special receivers began in Japan's major urban areas, although people, for now, can watch only the same programs shown on regular television sets in living rooms.

Japan's mobile TV technology isn't all that innovative or even the first to market. But it does show promise for linkups with entertainment downloads and other new services in a country already used to relying on the omnipresent mobile phone for everything from searching the Web for restaurants to paying for that meal. The new gadgets are essentially cellphones with antennas. They use an adaptation of digital broadcasts � the same ones that can be picked up by specially equipped digital television sets � rather than an Internet connection to relay video.

Hitoshi Mitomo, professor at Waseda University's graduate school of global information and telecommunication studies, believes regulations here need to be changed to foster new businesses that will make TV on-the-go attractive and trendy. "There are many hurdles from both the business side and the consumer side," Mitomo said. "What it needs is appealing content to watch on the handsets that offers ingenious lifestyle uses."

AI Agents Have Memory. Where is The Security?

Enterprise AI adoption keeps running into the same wall: the moment sensitive data, model weights, or agent memory leave a tightly controlled environment, security teams lose visibility into what happens to them while the workload is actually running. Confidential computing exists to close that gap, and new research from ABI Research shows the technology has matured enough, across CPUs, GPUs, containers, and now agentic AI, to become a foundational requirement for enterprises building sovereign AI infrastructure: computing environments they control end to end rather than simply rent. Protection is Moving From CPUs to GPUs ABI Research finds that CPU-based confidential computing is closest to mass-market adoption, the product of years spent hardening chip-level isolation for general workloads. GPU-based confidential computing is now generating the strongest momentum, and for good reason. It addresses one of the largest unresolved gaps in AI security: protecting data and models while inf...
