高品質(zhì)CTS晶振與高清電視HDTV
來(lái)源:http://m.wyss.net.cn 作者:金洛鑫電子 2024年01月02
高清電視(HDTV)是繼彩色電視之后視頻廣播領(lǐng)域最重大的突破。它通過(guò)提供比模擬廣播視頻更多細(xì)節(jié)和清晰度的更寬的圖像來(lái)增強(qiáng)觀看體驗(yàn)。
市場(chǎng)
高清已經(jīng)在全球范圍內(nèi)嶄露頭角。2006年初,高清廣播在12個(gè)國(guó)家播出:美國(guó)、加拿大、日本、澳大利亞、韓國(guó)、中國(guó)、德國(guó)和奧地利,以及北歐市場(chǎng)(瑞典、芬蘭、丹麥和挪威)。到2005年底,美國(guó)有1900萬(wàn)戶家庭擁有高清電視機(jī)(占電視家庭總數(shù)的17%),其中1100萬(wàn)戶家庭觀看高清廣播。與此同時(shí),14%(670萬(wàn))的日本家庭擁有高清電視。石英晶體振蕩器
在全球范圍內(nèi),到2010年底,高清家庭的數(shù)量預(yù)計(jì)將達(dá)到1.74億,占電視家庭的22%。這一數(shù)字在美國(guó)為59%,在日本為66%,在西歐為30%。北美的特點(diǎn)是美國(guó)的模擬截止時(shí)間為2009年2月17日,而拉丁美洲目前是DTT(數(shù)字地面電視)標(biāo)準(zhǔn)的開(kāi)放市場(chǎng);盡管如此,預(yù)計(jì)在未來(lái)幾個(gè)月內(nèi)將作出決定,開(kāi)始為這一地區(qū)增加定義。大多數(shù)預(yù)測(cè)都是基于TV House Hold數(shù)字,以及對(duì)模擬截止時(shí)間的預(yù)期得出的。
高清電視的基本原理
高清電視的基本概念是在保持投影尺寸的情況下,通過(guò)提供更高的分辨率來(lái)提高清晰度。(增加像素?cái)?shù))。
大多數(shù)提議的模擬和數(shù)字高清電視系統(tǒng)都在朝著水平和垂直像素增加大約100%的方向努力。(提案大約每幀1mb,大約1000行乘1000個(gè)水平點(diǎn))。這通常會(huì)導(dǎo)致垂直和水平油田方面的兩到三倍的改善。大多數(shù)HDTV提案還將寬高比從4/3改為16/9,使圖像與影院標(biāo)準(zhǔn)兼容。
CTS晶振如何支援高清電視廣播設(shè)備?
隨著高分辨率視頻點(diǎn)播(VOD)和視頻互聯(lián)網(wǎng)協(xié)議(IP)應(yīng)用需求的增長(zhǎng),設(shè)備制造商需要高頻參考vcxo和時(shí)鐘振蕩器來(lái)加密和解碼高分辨率視頻數(shù)據(jù)包。這種頻率源的精度范圍從+/-50PPM到+/-25PPM,在12KHz至20MHz帶寬范圍內(nèi)具有<1pS RMS的極低噪聲抖動(dòng)性能。所需的兩個(gè)最常見(jiàn)頻率是74.250 MHz和74.1258MHz或其倍數(shù)(頻率可能根據(jù)每個(gè)設(shè)備制造商使用的設(shè)計(jì)方法而變化)。
