repetition frequency-
G723 aerithemetic is a compressing arithemetic that proposed by itu - t and applied in speech and other audio frequency signals of low velocity multimedia services, such as : h. 323, h. 324 system. this arithemetic provides inspection to silence speech frames and fills in comfortable noise when it is silence. if optimize system and increase the complexity limitedly, we can get higher quality of speech. g723. 1 is also available in music or other voice signals, but the managing effect is not as good as speech ' s
G . 723演算法是itu - t建議的應用於低速率多媒體服務中語音或其它音頻信號的壓縮演算法，例如： h . 323 ， h . 324系統。這種聲碼器具備兩種比特率： 5 . 3kbps ， 6 . 3kps 。在幀邊界處可以在兩種速率之間進行切換。The standard is designed to give a new technical solution for a broad range of applications, such as very low bit rate conversational services and entertainment quality broadcast, interactive video - on - demand services etc. for the enhancement of the coding efficiencies, the new standard adopts new tools as following : multiple reference pictures, variable block - size with seven block sizes in motion prediction, quarter - pixel accuracy for motion vector, short word - length integer transform, context - adaptive entropy coding and loop filter deblocking
H . 264 / avc標準支持從低帶寬、高誤碼率的無線移動視頻通信到高帶寬、低誤碼率的有線視頻廣播等多種應用，因此，日益受到業界的關注。為了實現更高的編碼效率， h . 264 / avc標準採用了很多新的編碼技術，如多參考幀預測、多尺寸編碼塊模式、 1 / 4像素精度運動矢量、整數變換量化、基於內容的熵編碼、新型幀內預測、去除方塊效應的濾波器等。Digital video post - processing ic is designed for consumer video format conversion to attain high quality image, which mainly includes de - interlacing spatial conversions and picture rate conversion
視頻后處理晶元可以完成各種格式轉換，包括去隔行、空間縮放、幀率變換等等，進一步提高觀賞的效果。Aiming at the present condition of stb video post - processing, analyze the video post - processing algorithms which include sampling conversion, de - interlace and frame rate up - conversion
然後針對現行機頂盒視頻后處理現狀，分析了視頻后處理所採用的方法，包括采樣率轉換、去隔行、幀率提升等。分享友人
