Wavelet theory spiffs up video in computers
Article Abstract:
The Houston Advanced Research Center's HARC-C video compression software uses advanced wavelet mathematical theory to produce video compression ratios of 100:1 and 38 fps performance. The non-profit organization's P.K. Yuen and Charles K. Chui are credited with developing the new software. The software uses advanced wavelet technology to compress huge video data files into smaller, more manageable formats. Wavelets use frequency to compress data, which is accomplished more efficiently than traditional compression methods. The HARC-C software uses the technology to code video data into smaller pieces. It then reconstructs the data into a video image. The result is 38 fps performance without any noticeable loss of resolution. The software could produce a revolution in video technology, but skeptics contend that it will not have a significant influence because the computer industry has already adopted other standards for video compression.

FCC allows Telmex to operate in U.S. through a joint venture with Sprint
Article Abstract:
The FCC permitted Telefonos de Mexico (Telmex) to begin US operations on Jan 1, 1999, through its joint venture with long-distance carrier Sprint. The venture will bolster competition on the US-Mexico route as well as lower rates for US customers, according to FCC Chmn William Kennard. AT&T and MCI objected to the FCC approval, arguing that Telmex can capitalize on rules in Mexico. An AT&T statement said Mexico denied US telephone companies the right to resell service from Mexico to the US. Another AT&T charge said Mexico was violating its commitments to the World Trade Organization, but the Mexican government is rejecting the allegation. Kennard raised concern about two aspects of the US-Mexico route. One concern focused on an extended lack of progress on lowering settlement rates on the US-Mexico route, and the other centered on anticompetitive charges against Telmex.

Court weighs shielding children from Web smut
Article Abstract:
The Supreme Court will weigh the 1999 Child Online Protection Act's 'community standards' test, which a federal appeals court in Philadelphia ruled imposes 'an impermissible burden' on protected speech. The law makes it unlawful to post material considered 'harmful to minors' on the Web unless a genuine effort is made to keep it out of reach of children under 17.
