It has a built-in 181-chanel NTSC tuner, and Sony's Digital Reality Creation (DRC) mode, which doubles vertical and horizontal lines, resulting in four times the density for such high-quality video sources as DVDs, satellite broadcast, and digital camcorders. You do need a separate HDTV tuner to receive high-definition broadcasts. The KV36XBR450 has a Hi-Scan 1080i display that accepts the full 1080 interlaced scanning lines or 720 progressive scan (720p) from an external HDTV receiver or compatible high-definition digital satellite receiver. It also accepts 480 progressive (480p) scanning lines from compatible DVD video sources.
The KV36XBR450 offers a good range of Sony video technology. The Cinemotion 3:2 pulldown cinema video processing detects and compensates film--which is shot at 24 frames per second (fps) compared with video's 30 fps rate--to video for a smooth theaterlike experience at home. Using the Multi-Image Driver (MIDX), the Twin View function allows you to watch two programs side by side, with the ability to zoom into one picture. The 3D digital comb filter offers 10-bit signal processing that renders superb gradation of grays, resulting in superior picture detail.
The built-in DAC (digital acoustic chamber) speaker system features 4 speakers and has 7.5 watts of power output each. They produce TruSurround SRS 3D audio and simulated surround sound. Two component-video inputs (both at the rear) allow you to connect an optional HDTV receiver or a source with component-video outputs. It also has 4 A/V inputs (3 front, 1 rear), 3 S-video inputs (2 front, 1 rear), and 2 RF inputs (rear).
Tech Talk
Aspect ratio: The aspect ratio refers to the shape of the video image. 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, which is widescreen and appears rectangular, looking more like a movie screen and filling more of the viewer's field of vision for a more lifelike viewing experience.
Scanning method: Frames of video are made up of many lines of video 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, like a computer display.
