Progressive scan, About Scanning Mode

Progressive scan

The unit supports the Progressive scanning system as well as the conventional interlaced scanning system. If your television or monitor equipped with component jacks support the progressive video input, you can enjoy a high quality picture by making the Progressive scanning mode active.

Preparation:

•Connect to a TV equipped with component jacks.

•Turn On the TV and set it to the corresponding video input mode.

About SCANNING MODE

To display video on the television (monitor) screen, the conven- tional scanning method is called “Interlaced scanning.” With this method, only half of the horizontal lines are displayed at a time. So two fields complete a single picture (frame); i.e., the first field, containing all the odd-numbered lines, is displayed followed by the second field, containing all the even-numbered lines.

On the other hand, the Progressive scanning system scans all horizontal lines at a time, so you can double the number of pictures compared with the interlaced scanning, resulting in flicker-free, high-density picture.

To enjoy the progressive scanned video, a monitor (or TV or projector) to be connected to the unit must have the Progressive inputs.

Depending on the material source format, DVD VIDEO discs can be classified into two types; film source and video source (note that some DVD VIDEO discs contain both film source and video source). Film sources are recorded as 24-frame-per-second information, while (NTSC) video sources are recorded as 30- frame-per-second (60-field-per-second interlaced) information.

When the unit plays back a film source material, uninterlaced progressive output signals are created using the original information. When a video source material is played back, the unit interleaves lines between the interlaced lines on each to create the interpolated picture and outputs as the progressive signal.

NOTES:

•Some discs may not be played back with the progressive scanning mode correctly because of the disc characteristics or recording condition.

•There are some progressive TV and High-Definition TV sets that are not fully compatible with the unit, resulting in the unnatural picture when playing back a DVD VIDEO disc in the Progressive scanning mode. In such a case, use the Interlaced scanning mode. To check the compatibility of your TV set, contact your local JVC customer service center.

•You cannot make the progressive scanning mode active in following cases.

–The unit is in the VCR mode.

–The disc is played back in the DVD mode.

–The S-VIDEO/PROGRESSIVE video selector swich is set to S-VIDEO positon.
