State and National Bills to Recycle Old TVs & Computers – Oregon’s governor is about to sign a bill setting up a statewide process to allow discarded computers and video screens to be dumped safely, supported by recycling programs set up by the manufacturers. Oregon will be the seventh state to pass such a law, and the U.S. Congress is currently debating a national electronics recycling law, which would probably pre-empt the state laws.  The Oregon law applies to all desktop computers and laptops, and computer monitors and TV screens larger than four inches.  Any homes with seven or less electronic devices they need to dump at the same time will be given the locations of recycling centers and it will be no cost to them. Manufacturers will be asked to register with the state and pay a recycling fee determined by the number of products they sell in Oregon. New computers may see about a $1 price rise, with $6 to $8 expected on monitors and TV displays, in order to cover the cost of the recycling services. Oregonians alone discarded 32,500 tons of obsolete TVs, computers and electronics in 2005.

New Component Communication Standard – Many of the major Asian home electronics manufacturers are implementing a new communications standard called CEC (Consumer Electronics Control) in their AV receivers, DVD players, and TV displays. The new standard is based on the latest version of the hi-def multimedia interface connection, HDMI v1.3.  This is the sometimes-problematic but super-convenient solution to having only a single cable to deliver audio and video instead of seven or eight of them. HDMI 1.3 has the highest bandwidth and thus can carry the latest lossless digital audio formats: 7.1-channel Dolby True HD and DTS-HD Master Audio, starting to be offered on Blu-ray and HD-DVD discs. It also incorporates a much-needed automatic synchronization capability, which will allow it to achieve perfect lip sync in videocasts of all types when the video is delayed varying amounts due to image processing, thus putting it after the sound. It will also correct sync problems caused by AV signals being carried over long cables in some home theater setups.

Expansion of Color Palette in Video – Sony and Mitsubishi have collaborated on a technology to expand the bandwidth and range of different colors that can be sent from one video product to another. They claim that HDTV still delivers only about 60% of the shades of color that the human eye can see, and their x.v.Color system provides 92% of the colors the human eye can detect.  The catch is that so far there’s no program available reaching the new technology’s high standard. (Just as so far there’s no HD videocasts using 1080p instead of 1080i.) Mitsubishi is currently demonstrating their new sets featuring the capability using a special demo program on hard disc.
