US gets first mobile TV service

Verizon Wireless has introduced the first US commercial mobile television service in 20 states with full-length TV shows, reports Reuters.

The 24-hour service was developed by Qualcomm's MediaFlo unit and includes eight channels. Verizon says the picture quality is twice as clear as its existing video service and similar to standard TV.

The report says Verizon Wireless and its rivals have been pushing services such as video and music to boost revenue, but cellphone video services have been slow to take off due to high prices and poor quality.

Samsung Electronics has begun mass production of the industry's first 1Gb DDR2 DRAM, using a new 60nm process technology that increases production efficiency by 40%, reports Digitimes.

The report says Samsung expects increased demand for large density DRAMs because Microsoft's new premium Windows Vista operating system imposes a DRAM requirement of at least 1GB.

Samsung's continuous technology migration below 90nm has relied heavily on the company's extensive use of three-dimensional transistor technology to build increasingly smaller chips.

A security researcher has warned that a new attack technique increases the risk of commonly found bugs in Oracle's database software.

News.com says according to security expert David Litchfield, the new attack technique means attackers no longer need high-level privileges on the database to exploit known PL SQL injection vulnerabilities. Litchfield says the new cursor injection technique enables attackers with minimal privileges to gain complete control of the database server.

Oracle says it is aware of the new attack technique. The company has advised customers to apply patches it has provided to fix known flaws.

Russia's oldest theatre has installed equipment to block mobile phone signals to force patrons to stop taking calls during performances.

IOL says patrons accepting calls on their cellphones regularly interrupt all public performances in Russia.

A spokesman for St Petersburg's Alexandrinsky theatre says although the technology is expensive, the theatre's management has decided to take the step to protect performers from unpleasant surprises.
