  • • Could cybercriminals use your new Internet TV to infiltrate your home or business? Security Week writer Mike Lennon's article Researchers Hack Internet Enabled TVs, Discover Multiple Security Vulnerabilities raises this possibility. "During the course of its research, Mocana, the security firm that discovered the flaws, demonstrated that the TV's Internet interface failed to confirm script integrity before scripts were run. As a result, an attacker could intercept transmissions from the television to the network using common 'rogue DNS', 'rogue DHCP server', or TCP session hijacking techniques. Mocana was able to demonstrate that JavaScript could then be injected into the normal datastream, allowing attackers to obtain total control over the device's Internet functionality. "

  • • Verizon sees a future in Mobile TV. Mark Milian from CNN writes about this in Verizon takes steps towards launching TV Everywhere service. In the article, he includes this statement made at the recent CES by Verizon's CEO, Ivan Seidenberg. "We're changing the game again across all of our networks--wireless, broadband, the Internet backbone and the cloud. Consumers are actually watching more TV than ever before. What's changing the game is how they're watching."

  • • For a somewhat biased view of broadcasters' use of spectrum, also see Larry Downes's article Spectrum worries at CES: Deja vu all over again. He notes that "According to Tom Wheeler of Core Capital Partners and a longtime industry veteran, only 2 to 3 Mbps are needed for the digital TV signal itself. Assuming technical issues are resolved, broadcasters could give up much of their allocations without interfering with their ability to broadcast." Any broadcast engineer knows that statement is valid only if the "digital TV signal" consists of one standard-definition channel. Even by using H.264 compression (incompatible with existing TV sets), it's difficult to do high quality HDTV in less than 6 Mbps. One mobile stream takes about 2 Mbps of data bandwidth.
