電視概念請教
基於現行既高清數碼廣播係1080i/30fps, 咁當呢個訊號去到我部1080P 50Hz電視, 咁究竟會係一秒鐘播30張定係會50張呢?外國有些高清數碼廣播係用720p/60fps, 咁如果兩種source去到我部電視,係咪應該會720P/60fps會流暢好多呢? 基於現行既高清數碼廣播係1080i/30fps, 咁當呢個訊號去到我部1080P 50Hz電視, 咁究竟會係一秒鐘播30張定係 ...

Oh, thanks c hing's info x 2
咁即係當1920 x 1080i/25 fps既訊號黎到我部電視既時候,咁我部50hz既電視究竟會每秒鐘播幾多張呢?25 / 50? 或者再簡單D咁問,係咪即係當我睇高清電視既時候,個廣播制式720P/50fps係會流暢過1080i/25fps? 回復 6# chung190030
據我所知,電視係會將25Hz->50Hz來播,最簡單就係將同一個frame播兩次,25x2=50,當然如果原生fps高,當然會順。其實我地睇到ge畫面,只係一連串有連繼性的圖片快速播放。 或者再簡單D咁問,係咪即係當我睇高清電視既時候,個廣播制式720P/50fps係會流暢過1080i/25fps? ...

係 720P/50Hz (50fps?) 順過 1080i/25Hz (25fps) 的。
但我覺得畫面無咁 DETAIL,無咁靚。 回復 8# plnl88

其實係因為我睇HD Jade既時候,成日都會覺得D野好似有鬼影咁樣,但係睇blu-ray又唔覺有喎,所以先至google一下啫! 回復plnl88
