SK8855 Multimedia Controller

SK8855為一高性能及高整合度的影音多媒體播放晶片。主要可運用於數(shù)位相框 (Digital Photo Frame)，多媒體播放機 (MultiMedia Player)，液晶電視(LCD TV)，和車用電視 (Car TV)。此多媒體播放晶片可對許多不同影音做即時解碼。

支持的影音多媒體解碼格式包括 :
聲音 : MP3, WMA, AAC-LC, OGG-Vorbis, PCM, ADPCM
圖檔 : JPEG, BMP, GIF, TIFF
影音 : M-JPEG, MPEG-1, MPEG-2, MPEG-4 (DivX/Xvid), H.264, VC-1, 3GP, FLV

在靜態(tài)圖像解碼可支持高解析度電視(HDTV, 1080p)的撥放。兩千萬畫素的 JPEG照片可於二秒內(nèi)解碼撥放。而且相較於市面上的同級產(chǎn)品，是唯一可支持3GP、H.264、FLV格式的解碼晶片。支持的影音格式眾多，不需要用PC來預先轉(zhuǎn)檔。提供BT, WiFi, 3G/3.5G之網(wǎng)路連接功能，支援RSS Protocol，並支援NAS網(wǎng)路硬碟。獨創(chuàng)之Texture Graphic Engine提供客戶更多樣化之使用者介面。支援多種最新記憶卡格式如SD/MMC, MS/MS-Pro, xD/SMC及CF等等。?
