全面了解 DVD 解析度 [解釋]

Have you noticed varying video quality when playing your DVDs? For example, others have better quality than the one you’ve played before. This difference often comes down to the resolution and format of the DVD, as they are not often the same. In this guide, we'll explore what DVD resolution is, why it matters, and how you can change it. We'll also discuss how DVD quality differs from Blu-ray and provide you with practical tips on adjusting DVD resolution for optimal playback. Continue reading to know more.

第 1 部分：什麼是 DVD 分辨率

解析度是指視訊影像中的像素數，以寬度 x 高度表示。通常，我們可以在串流媒體平台上輕鬆識別視訊分辨率，它可以調整視訊的品質。與 DVD 一樣，各種解析度都會影響 DVD 影片播放的品質。以下是 DVD 解析度的類型：

NTSC DVD Resolution: 720 x 480 pixels can be displayed in either 480i or 480p formats. This resolution is Standard Definition or SD, is compatible with NTSC television systems, and is commonly used in North America and parts of Asia.

PAL DVD Resolution: 720 x 576 pixels. This resolution supports 576i and 576p formats, providing slightly higher quality compared to NTSC DVDs. Also, it is commonly used in Europe, Australia, and other regions.

Note: Both NTSC and PAL DVD resolutions are available in both 4:3 and 16:9 aspect ratios.

最後，DVD 的最大解析度為 480i/p 或 576i/p，這意味著 DVD 僅限於標準清晰度品質。

第 2 部分。 DVD 品質與藍光

藍光光碟是一種專為播放高清格式而設計的數位光碟。就畫質而言，DVD 的品質略有不足，請參閱下表以了解這一點：

This table shows that there are indeed differences between DVD quality vs. Blu-ray. DVDs are limited to SD or Standard Definition when it comes to the resolution, but Blu-ray can deliver an HD video up to 4K. Additionally, Blu-ray offers a larger storage capacity than DVD’s capacity. But in terms of compatibility, HD is more flexible as it can be played on both DVD and Blu-ray. Nevertheless, this comparison does not determine which is the best. This is to give you a picture of what you can expect more of your DVD resolution.
