Description
本發明有關影片播放系統，尤指一種用於動態產生縮放影片的多螢影片播放系統和相關的電腦程式產品。 The invention relates to a video playing system, in particular to a multi-flash movie playing system and related computer program product for dynamically generating a zoomed movie.
傳統的影片播放系統都是單螢幕系統。不管消費者是到電影院看電影，或是在家中利用家庭劇院設備看電影或電視節目，都只能依賴預先固定架設好的單一螢幕來觀看影片的內容。因此，在影片播放的過程中，若影片的觀看者對影片中的某個局部區塊的影像內容特別感興趣，而想放大該局部區塊的影像來觀看影像細節，將會遭遇到許多問題。 Traditional movie playback systems are single screen systems. Whether the consumer is going to the cinema to watch a movie, or using a home theater device to watch a movie or TV show at home, they can only rely on a single screen that is pre-fixed to watch the content of the movie. Therefore, in the process of playing a movie, if the viewer of the movie is particularly interested in the image content of a certain partial block in the movie, and wants to enlarge the image of the local block to view the image details, many problems will be encountered. .
首先，前述局部區塊的影像放大後的影像品質，主要取決於影片的解析度以及影片播放系統的影像縮放運算效能。若影片的解析度不夠高，或是影片播放系統的影像縮放運算效能不足，則局部區塊的影像放大後的影像品質將很難讓人滿意，也無法呈現足夠清晰的影像細節給觀看者欣賞。 First, the image quality of the image of the local block is mainly determined by the resolution of the movie and the image scaling performance of the video playback system. If the resolution of the video is not high enough, or the image zooming performance of the video playback system is insufficient, the image quality of the image in the local block will be difficult to satisfy, and the image details that are clear enough cannot be presented to the viewer. .
另外，在傳統單螢幕架構的影片播放系統中，當放大前述局部區塊的影像時，勢必會遮蔽到影片中其他區塊影像的顯示空間，而影響到所播放的影片內容的完整性。 In addition, in the conventional single-screen video playback system, when the image of the local block is enlarged, the display space of other block images in the movie is bound to be hidden, which affects the integrity of the content of the played video.
再者，在同時有多人一起觀看同一部影片的場合中，不同的人可能會對影片中的不同區塊的影像內容感到興趣。傳統單螢幕的影片播放系統顯然無法同時提供不同區塊影像的放大版本給不同的人觀看。 Furthermore, in the case where many people watch the same movie together, different people may be interested in the video content of different blocks in the movie. The traditional single-screen movie playback system obviously cannot provide an enlarged version of different block images for different people to watch at the same time.
倘若不能擴充現有的影片播放系統中的螢幕數量，電影或電視節目的製作單位便難以提供更多元化的影片呈現方式，消費者也難以獲得更豐富和不同於以往的影片觀賞體驗。 If the number of screens in the existing video playback system cannot be expanded, it will be difficult for the production unit of the film or television program to provide a more diversified film presentation mode, and it will be difficult for consumers to obtain a richer and different movie viewing experience.
