Zenith C34W23 34-Inch Widescreen Integrated HDTV

The C34W23 offers a number of high-definition features that provide amazing picture clarity. The 34-inch flat, fine-pitch picture tube with Invar shadow mask provides the sharpest and clearest picture possible. The 3D Y/C comb filter combines the adaptive digital processing of a 3-line digital comb filter with 3D motion detection to eliminate hanging dots and color noise on stationary images. The Dynamic Focus feature ensures accurate side-to-side focus and alignment of red, green, and blue color beams to the center of the screen.

With the 16:9/4:3 aspect ratio correction function, you can watch Hollywood movies in their original widescreen format (16:9) or in standard TV format (4:3). Other features include a color temperature control--which lets you adjust the ambiance of the screen's picture between warm, mid, and cool presets--built-in 14-watt speakers (7 watts per channel), Dolby Digital sound output, front surround-sound function to simulate 3D sound, trilingual menus (English, French, and Spanish), and MTS/SAP audio broadcast.

Tech Talk

• DCDi: A video-mode algorithm that stands for Directional Correlation De-interlacing. It was designed for video-based material like fast-paced sporting events, and its purpose is to eliminate jagged edges ("jaggies") along diagonal lines caused by interpolation.
• Active lines: Scanning formats are measured in active lines of picture elements or pixels transmitted, both horizontal and vertical. The number of total pixels is calculated by multiplying the amount of vertical lines by the density of horizontal picture elements. For example, the 1920 x 1080 HDTV format has more than 2 million pixels (1920 x 1080 = 2,073,600). Today's NTSC video only has a resolution of 211,200 pixels (480 vertical lines and 440 horizontal pixels).
• Aspect ratio: The aspect ratio refers to the shape of the video image. Today's standard television has a 4:3 aspect ratio, which is almost square in appearance. Digital television will have either a 4:3 or 16:9 aspect ratio. A 16:9 aspect ratio is widescreen and appears rectangular--it looks more like a movie screen, filling more of the viewer's field of vision to yield a lifelike viewing experience.
• Scanning method: Frames of video are made up of many lines that are scanned onto a television screen so closely they appear to be a solid picture. The scanning method can be either interlaced or progressive. Interlaced scanning (also used in today's analog TV), indicated by an "i" in the video format, fills in the odd number lines (1,3,5,7...) and then fills in the even number lines (2,4,6,8...) until the frame is complete. Progressive scanning, "p," fills in each line consecutively until the frame is complete, creating a seamless image.
• Frame rate: Also known as picture rate, the frame rate is the speed at which the lines are scanned in order to create a video frame--60, 30, or 24 frames per second.
