3、l CES”上演示了采用H.264/MPEG-4 AVC方式的影像實(shí)時(shí)編碼。該公司曾在2004年10月舉行的“CEATEC 2004”上以1.5Mbit/秒的速度演示過(guò)720×480像素的SDTV影像的編碼，HDTV影像的演示尚屬首次。 將1920×1080像素、60幀/秒的HDTV影像輸入設(shè)備，然后進(jìn)行了實(shí)時(shí)編碼。編碼器支持的協(xié)議為Main Profile、級(jí)別為4.1。編碼數(shù)據(jù)速度為可變，平均值為9Mbit/秒。 為實(shí)現(xiàn)這一編碼速度，在一個(gè)機(jī)殼內(nèi)嵌入了3枚支持SDTV編碼的板卡。據(jù)說(shuō)，在CEATEC上只使用了一枚這樣的板卡。此次將畫(huà)面按上下方向分為三個(gè)區(qū)域，每個(gè)區(qū)域的編
