The realization of video line output DVD movie to pure HD video

What is the line-increasing output? DVD discs vary according to the television format used (NTSC or PAL), and their screen resolutions are 720x480 (480I/P) or 720x576 (576i/p) respectively. Obviously, the quality of the DVD is far less than the current most popular HD video standard--1280x720 (720i/p) or 1920x1080 (1080i/p) requirements. To put it simply, watching a DVD movie on a large-screen flat-panel TV that supports high-definition resolution is not very clear and the visuals are not satisfying. As a result, many recently released DVD players have added a practical "line" (also known as line, frequency) function, will be the screen resolution from the DVD machine 720x480 upgrade to 1280x720 or 1920x1080 high-definition video standards.

Under normal circumstances, the DVD machine's line-increasing function mainly utilizes a special video Scaler DSP chip to carry on the operation to the DVD signal, its principle is not only carries on the pure picture size enlargement processing, it uses the de-interlacing (reverse interleaving) technology to resample the DVD picture, The screen resolution to meet the 720i/p or 1080i/p standards, and effectively eliminate the resolution to improve the screen is very loose, foggy feeling, so that DVD can be in the Blu-ray and HD-DVD and other high-definition video disc standards under the attack can continue life cycle.

When you see this, a fast-thinking friend might think: "I don't have a DVD player with the line, but I have a PC that's connected to a high-definition TV, can I play a video-line output when I play DVDs on my computer?"

Of course you can! The method is to use a well-known multimedia playback software zoom player, as well as external video decoder and DVD Video decoder plug-in tools to achieve with the DVD player line output similar to the quality improvement. Below, I will discuss with you how to achieve the video on the computer output line, so that people do not spend extra money will be able to get "HD" Quality of enjoyment.
