【摘要】：隨著科學(xué)技術(shù)的不斷發(fā)展,在電影領(lǐng)域,超高清(UHD)以及4K視頻出現(xiàn)取代高清(HD)格式的趨勢(shì)。為保證UHD/4K影片的高效和高質(zhì)量傳輸,新的視頻編碼算法要在UHD比HD多出三倍數(shù)據(jù)量的同時(shí),保證相同的傳輸質(zhì)量,并在傳輸帶寬相同的情況下,盡量保持與HD相同的傳輸時(shí)間。本文分析了當(dāng)前電影行業(yè)的原始視頻格式,以及當(dāng)前主流高清電影所采用的H.264視頻格式。介紹了視頻壓縮技術(shù)的發(fā)展過(guò)程,并對(duì)比介紹了H.265標(biāo)準(zhǔn)相對(duì)于其他視頻壓縮標(biāo)準(zhǔn)的優(yōu)缺點(diǎn),從原理上解釋了采用H.265的必要性。第三章,對(duì)比了目前主流的視頻壓縮質(zhì)量評(píng)估技術(shù)方案。第四章,結(jié)合公司在視頻壓縮的需求,確定視頻編碼方法的使用,并設(shè)計(jì)符合需求的硬件播放器。第五章,定義了軟件的基本功能需求,并介紹了軟件外包團(tuán)隊(duì)所需編解碼軟件。第六章,針對(duì)四五章所設(shè)計(jì)的軟硬件進(jìn)行測(cè)試,在修正一系列BUG后,實(shí)驗(yàn)表明,所涉及方案明顯優(yōu)于目前主流的H.264壓縮方式,圖像質(zhì)量顯著高于H.264以及主流的H.265 4K 420 8 bit。達(dá)到公司項(xiàng)目的初步需求。
[Abstract]:With the continuous development of science and technology, ultra-high definition (UHD) and 4K video appear to replace high definition (HD) format in the field of film. In order to ensure the efficient and high quality transmission of UHD/4K films, the new video coding algorithm should ensure the same transmission quality while UHD produces three times more data than HD, and under the same transmission bandwidth, Try to maintain the same transmission time as HD. This paper analyzes the original video format of the current film industry and the H.264 video format used in the current mainstream high-definition movies. This paper introduces the development process of video compression technology, compares the advantages and disadvantages of H.265 standard compared with other video compression standards, and explains the necessity of adopting H.265 in principle. In the third chapter, the mainstream video compression quality evaluation technology scheme is compared. The fourth chapter, combined with the requirements of the company in video compression, determine the use of video coding methods, and design a hardware player to meet the requirements. In the fifth chapter, the basic functional requirements of the software are defined, and the coding and decoding software needed by the software outsourcing team is introduced. In the sixth chapter, the hardware and software designed in Chapter 4 and 5 are tested. After modifying a series of BUG, the experiment shows that the scheme involved is obviously superior to the current mainstream H.264 compression mode. The image quality is significantly higher than H.264 and mainstream H.265 4K 420 8 bit.. Meet the initial needs of the company's projects.
