The DV-79AVi Elite DVD player features an upgraded version of the Pioneer-trademark Digital Direct Pixel Drive™. If you connect the player with a compatible A/V receiver or plasma display panel via the HDMI terminal, the advanced technology allows all-digital signal processing and transmission — with high 10-bit precision thanks to the "VQE9" video-encoding LSI. Because the signals remain digital, they are free from conversion loss, delivering pictures with less noise and finer details than those with analog conversion. The player also converts up pixels for HDMI output. (See the figure at the bottom of the page.)

VQE9 Video-Encoding LSI

The Advanced Digital Direct Pixel Drive™ features VQE9 video-encoding LSI. This state-of-the-art device allows expansion to 10 bits, and all the processes for improving picture quality are performed on a single chip, including:

•Effective noise reduction with Component Frame DNR Pro (see page 23 for details)

•Highly-precise motion detection for more natural textures and smoother edges of moving images from video sources

•A wide variety of picture adjustment options

•High-resolution progressive pictures (PureCinema Progressive Scan)

"Two-Dimensional Resolution Expander": Pixel Conversion IC for HDMI

The Advanced Digital Direct Pixel Drive™ also features the

"Two-Dimensional Resolution Expander" pixel conversion IC,

When video signals are output to non-HDMI devices, the Elite DVD player uses the high-grade 108 MHz/14-bit video D/A converter. Combining 8x oversampling with high 14-bit precision, this premium device ensures superior linearity by preventing phase fluctuations. The converter also controls overshoot and undershoot without affecting the original signals, even when the picture has high contrast.

Interlaced vs. Progressive Scanning

• Interlaced scan system — NTSC TV Standard

When you look at your TV screen close up, you will notice an image is made up of many horizontal lines. These are called scan lines: an image is painted on the screen by the scan lines that sweep from left to right, and top to bottom, in sequence. One screenful of TV picture is equivalent to a frame; by current NTSC TV standards there are 480 scan lines in each frame (480i).

All 480 scan lines that form an image are not sent to your TV at the same time; every other line is transmitted alternately every 1/60 second. In other words, in the first 1/60 of a second, odd-numbered lines (1st, 3rd, 5th, and so on), which total 240 and collectively form an odd-numbered field, are sent. In the next 1/60 of a second, even-numbered lines (2nd, 4th, 6th, and so on), which collectively form an even- number field, are transmitted to fill in the remaining space. In this way, a complete image, that is, a frame, is formed.

Such is NTSC interlaced scanning. With this system, lines are scanned for odd- and even-numbered fields alternately every 1/60 second, to build one frame every 1/30 second.

• Progressive scanning for double resolution of interlaced scanning

With interlaced scanning used by NTSC TV standards, the

larger the display, the more noticeable the picture flicker.

2-3 Pull-down PureCinema Progressive Scan Technology

Normally there are 24 frames per second (24fps) on film. On DVD, movies are recorded in the same 24fps format, each frame containing the data for the entire 480 scanning lines (480p) for progressive scanning. Pioneer's 2-3 Pull-down PureCinema Progressive Scan Technology is exactly the technique to take advantage of delicately nuanced images recorded by progressive scanning. DVDs hold the data for inverse telecine conversion: When playing back film-originated sources, Pioneer's advanced scanning technology makes use of the data and inserts additional frames accurately. This allows the viewer to enjoy natural, film-like images. Pictures are smooth and sharp, with high resolution, free of bothersome artifacts like jagged edges on moving objects.

Note: With the DV-46AV, PureCinema Progressive Scan directly turns 24fps progres- sive images from DVDs into 60fps progressive images. Because conventional progres- sive-interlace-progressive conversion is not used, this represents simpler, more efficient way of conversion.

Note: To enjoy the advantages of PureCinema Progressive Scan Technology, your TV must be compatible with D2 or higher component video formats. The RCA-pin type component video output offers purer colors and finer gradations.

Progressive scanning was developed to solve this problem.

With progressive scanning, all 480 lines are scanned from top to

bottom in 1/60 of a second to build an entire frame (480p).

With a progressive scan TV, the data for the odd- and even-

numbered fields is stored in memory and undergoes field

interpolation to convert from 30fps (frames-per-second) format

to 60fps simulated format. Therefore, progressive scanning can

provide double resolution of interlaced scanning, to present

high-quality images with less flickering.

DVD boasts a horizontal video resolution of more than 500 lines. Unfortunately, high resolution brings about a drawback of its own: minute noise is more visible. So Pioneer developed component frame cycling DNR (Digital Noise Reduction). It discriminates noise in each of the three components that comprise video signals — Y (luminance), PB and PR. Since it compares consecutive frames rather than consecutive fields, and processes individual components rather than composite signals, DNR provides superb noise reduction capability while retaining high resolution.
