Sony debuts its first 55" LCD Rear Projection Television with the KDF-55WF655 Grand WEGA High Definition Television. Featuring a high definition integrated television display, ATSC integrated tuner and 3.28 million dots resolution, the KDF-55WF655 produces stunning picture resolution. In addition to a CableCARD Slot, it features CineMotion Reverse 3-2 Pulldown Technology allowing for enhanced customization and a slim tabletop design that is sure to compliment any decor. You can even listen to MP3 audio and view your photos with the built-in Enhanced Memory Stick Media slot.

Weighing in heavy on style, features, and quality, Sony's cutting-edge, 55-inch KDF-55WF655 is nevertheless a lightweight when it comes to heft. That means the 101-pound LCD projection television is easy to position, and its relatively modest chassis--standing under 20 inches deep--won't push you out of your house. The set is also loaded with great features, from integrated NTSC and ATSC (HDTV) tuners to Sony's WEGA Engine system, digital cable readiness, and the latest digital-video interface, HDMI.

The set's 1,366 x 788 liquid-crystal display frees you from having to make convergence adjustments or having to worry about image burn-in. Instead you get incredible detail (more than 3 million pixels), high contrast, and even, corner-to-corner brightness from the set's user-replaceable 132-watt UHP (ultra high pressure) lamp.

The screen features a wide, 16:9 aspect ratio to match the dimension of most movies and HDTV broadcasts, and the KDF-55WF655 offers compatibility with standard-definition 480i, enhanced-definition 480p, and high-definition 720p and 1080i signals. Sony's Digital Reality Creation (DRC) circuitry ensures high picture resolution, while proprietary Direct Digital Circuitry increases a video signal's signal-to-noise ratio before it reaches the DRC circuit, ensuring rich, natural-looking images from any source.

Sony's CineMotion 3:2 pulldown detection and reversal is a handy feature for watching progressive-scan movie programs in their native 24-frame format. Digital video mastering introduces a common distortion when adjusting 24 frames-per-second movies to 30 fps video; 3:2 pulldown digitally corrects this distortion, removing the redundant information to display a film-frame-accurate picture.

The set's WEGA Engine system maximizes picture performance from any video source by minimizing the number of digital-to-analog conversion processes. This full digital processing engine includes Sony's MID-X (Multi Image Driver), which maintains the integrity of a converted signal by minimizing image loss in the scaling process; and a proprietary optical engine, which employs a trio of Sony's wide-XGA, high-resolution LCD panels, 1 for each of the RGB signals (resulting in a total of 3.28 million dots of resolution).

The optical engine also features a special 11-element lens system responsible for the lightweight, ultra-slim cabinet. The lens system bends the light path, creating an ultra-short focal point while maintaining high brightness. This proprietary system delivers vivid images from the center of the screen all the way to the edges.

The set includes numerous other features.

  • TwinView PIP (picture-in-picture) lets you view any 2 sources simultaneously, even at different image resolutions, while the built-in Memory Stick media slot offers ready display of both JPEG images and MPEG-1 video.
  • A Memory Stick media slot (compatible with Memory Stick Pro and Memory Stick Duo media) grants convenient viewing of JPEG and MPEG-1 files. It can also display customized slide shows using MP3 files for background music.
  • Channel Fix lets you select a specific TV channel (3, for example) for cable box reception. Then you can control a compatible cable box via the TV remote without inadvertently changing the TV from Channel 3.
  • Authorized CableCARD ability means the set will receive digital cable television systems services directly from the cable operator without requiring a bulky, external cable box.
  • Sony's exclusive S-Master 1-bit digital amplifier produces 15 watts per channel (x 2), ensuring high power for superb, clear dialog.

HDMI (High-Definition Multimedia Interface) is a lossless, uncompressed, all-digital audio/video interface to link the set with any audio/video source (such as a set-top box, DVD player, or AV receiver). HDMI supports standard-definition (SD), enhanced definition (ED), or high-definition (HD) video, plus multi-channel digital audio--all using a single cable. It transmits all ATSC HDTV standards and supports up to 8-channel digital audio, with bandwidth to spare to accommodate future enhancements and requirements.

Linear Algebra and Its Applications, 3rd Updated Edition (Book & CD-ROM)

Linear algebra is relatively easy for students during the early stages of the course, when the material is presented in a familiar, concrete setting. But when abstract concepts are introduced, students often hit a brick wall. Instructors seem to agree that certain concepts (such as linear independence, spanning, subspace, vector space, and linear transformations), are not easily understood, and require time to assimilate. Since they are fundamental to the study of linear algebra, students' understanding of these concepts is vital to their mastery of the subject. Lay introduces these concepts early in a familiar, concrete Rn setting, develops them gradually, and returns to them again and again throughout the text so that when discussed in the abstract, these concepts are more accessible.
