deinterlace To convert an interlaced image to a progressive scan image. Also called "I to P conversion," deinterlacing is built into most DVD players, A/V receivers, video processors and digital TVs. Most broadcast TV is delivered in 1080i resolution (1080 lines "I"nterlaced) and many DVDs include interlaced content. Deinterlacing fills in the missing lines so that 60 full frames per second can be displayed on HDTV sets. See interlace.EASIER: Film to Interlaced to Progressive When a movie shot on film is converted to video, all original content is available in the video frames. Each full movie frame is turned into two interlaced video half frames (see telecine for details), and the half frames can be readily converted back into full frames, restoring the original, progressive sequence. The cadence detection in the deinterlacing process analyzes the frame sequence to determine if the video was originally film in order to deinterlace the frames in this manner (see cadence correction). MORE DIFFICULT: Interlaced to Progressive When shooting with a video camera, interlaced video is generated from the start, in which even lines are captured for one half frame followed by the odd lines in the next half frame and so on. Since the camera keeps running and generating half frames, every other line is actually missing in the video frames. In order to deinterlace this originally interlaced video, either the existing even and odd lines are duplicated, called "line doubling," or the missing lines are filled in by analyzing the half frames before and after each half frame. This is where one algorithm can be vastly superior to another. See interlace, DCDi and telecine.

No references found | Advanced features in the BCM3560 include picture-in-picture (PIP) capabilities, an advanced 3-D comb Y/C standard separation circuitry, a multi-field de-interlace circuitry, proprietary picture improvement functions, digital and analog video output interfaces and video scalars. To optimize quality, producers should scale and de-interlace their footage in their video editors, or with a third-party tool like Algolith from AlgoSuite. I also believe the advanced de-Interlace and scalar technologies incorporated in our products will give us a leading position in the emerging display marketplaces in China and Asia Pacific. |
