JBL CVPD50, CVR700 manual P and i designations stand for progressive and interlaced

Plasma Display. Composite, S-video and component video monitor outputs on the CVR700 are provided as a means of con- necting an auxiliary display only. On- screen status messages, and all digital video post-processing – including scaling, de-interlacing, and upconversion features of the CVR700 – are only available when used with the CVPD50.

When using the CVR700 with the CVPD50 display, there is no need to use the CVR700’s component video outputs. All video signals, including those from the internal DVD/changer as well as those originating with external source devices, are upconverted to the digital format uti- lized by the single proprietary interface cable between the CVR700 and the CVPD50.

High-Definition Television (HDTV): HDTV is a form of digital television that advances picture quality by leaps and bounds over conventional analog televi- sion. HDTV signals are broadcast in a dig- ital format that compresses the signal, allowing far more information to be sent. Broadcasters take advantage of the addi- tional bandwidth by offering high-resolu- tion images containing millions more pix- els than an analog picture, the end result being an image so sharp it looks more like a photograph than television.

The resolution of a digital video signal can vary, depending on the number of pix- els used, and whether the image frames are interlaced or progressive. Conventional television uses interlaced frames, in which first the odd horizontal pixels are scanned, then all of the even pixels are scanned to display one frame. Progressive scanning, as described below, displays all of the horizontal lines of pixels in one pass. These are the common digital video formats:

•480i – The picture is 704 x 480 pixels, sent at 60 interlaced frames per sec- ond (30 complete frames per second).

•480p – The picture is 704 x 480 pixels, sent at 60 complete frames per second.

•720p – The picture is 1280 x 720 pix- els, sent at 60 complete frames per second.

•1080i – The picture is 1920 x 1080 pixels, sent at 60 interlaced frames per second (30 complete frames per second).

•1080p – The picture is 1920 x 1080 pixels, sent at 60 complete frames per second.

The “p” and “i” designations stand for “progressive” and “interlaced.”

The 480p and 480i (when digital) formats are called the SD (standard-definition) formats, and 480i is the digital equivalent of a normal analog TV picture. When ana- log TV shows are upconverted and broad- cast on digital TV stations, they are broadcast in 480p or 480i.

The 720p, 1080i and 1080p formats are HD (high-definition) formats. When you hear about “HDTV,” this is what is being discussed – a digital signal in the 720p, 1080i or 1080p format. If your HD source allows you to choose a picture resolution, set it to 720p, which works best with the CVR700 and CVPD50.

Strictly speaking, the 480p format is con- sidered ED (enhanced definition). However, the JBL Cinema Vision system processes 480p signals as high-definition, and when referring to high-definition signals, we will be talking about 480p or better images.

JPEG Files: JPEG stands for the Joint Photographic Experts Group, which devel- oped a standard for compressing still images, such as photographs. JPEG files may be created on a personal computer by importing images from a digital cam- era, or scanning printed photographs. These files may be burned onto a com- pact disc. The CVR700 is among the DVD players that are capable of recognizing JPEG files and enabling you to view them on your video screen.

MP3 Files: MP3 is an audio compression format that was developed by the Motion Picture Experts Group as an adjunct to the MPEG-1 video compression format. A number of encoding software programs are available for transferring CDs and other audio programs into the MP3 for- mat. The main benefit of MP3 is that it reduces the size of audio files consider- ably, depending on the amount of com- pression selected during the encoding process, enabling you to store many more songs on one compact disc than in the standard audio CD format. The CVR700 is capable of playing MP3 files and display- ing the filenames on screen.

Multiple Angle: DVDs have the capabil- ity to show up to four different views of

the same scene in a program. When a disc is encoded with multiple-angle infor- mation, pressing the Angle Button E 15 will enable you to switch between these different views. Note that, at present, few discs take advan- tage of this capability and, when they do, the multiple-angle technology may only be present for short periods of time with- in the disc. Producers will usually insert some sort of icon or graphic in the picture to alert you to the availability of multiple- angle scenes.

Progressive scan: If you are using the CVR700 with the CVPD50 display, and with no external DVD players, you may skip this section, as the internal DVD player outputs a digital video signal that is passed directly to the CVPD50 using the proprietary interface cable. The CVR700 offers progressive scan video outputs for use with compatible high-res- olution televisions and projectors. Before DVD, no consumer medium could store, transmit or display video with full resolu- tion. To conserve bandwidth, analog com- pression (interlacing) is employed: first the odd-numbered lines of a frame are displayed, followed by the even-num- bered lines. The result is that only half of the video image is drawn at one time; the viewer’s brain must reassemble the com- plete image. This is acceptable, if the monitor is not too large and if there is not too much motion in the image. Large dis- plays and fast-moving images reveal the limitations of this system. Thanks to DVD’s immense data capacity, images are now stored intact (progressively), so that all the lines in each frame (odd and even) are shown at the same time. But because most TVs cannot handle a progressive signal, all current DVD players generate an interlaced output for compatibility. The CVR700 is among the select few DVD players with true progressive scan video output for use with compatible TVs and CRT projectors and with all plasma, LCD and DLP display devices via the compo- nent video output. The result is 40% greater light output than a conventional TV and a stunningly detailed high-defini- tion image, along with an almost com- plete absence of visible scanlines and motion artifacts. The CVR700’s sophisti- cated pixel-by-pixel processing is a major advancement over the previous genera- tion’s line-by-line processing, bringing out even greater detail in your favorite video presentations.
