移動終端流媒體播放器的設(shè)計與實現(xiàn)[畢業(yè)設(shè)計論文報告+相關(guān)答辯表格+文獻(xiàn)翻譯]

摘  要

隨著科技的日新月異，流媒體技術(shù)的發(fā)展已經(jīng)達(dá)到了從量變到質(zhì)變的關(guān)鍵時刻，流媒體必將成為個人電腦的網(wǎng)絡(luò)設(shè)備的主流，并且對人們的日常生活以及媒體傳播有著極其巨大的影響。為了開發(fā)出更好的播放器，銷售商們付出了巨大的努力。技術(shù)和計算機技術(shù)的迅猛發(fā)展, 使得人們對手持設(shè)備的應(yīng)用有了更高的要求, 人們已 不滿足于簡單的通話, 收發(fā)短信等 基本功能, 而更多的是要求有多媒體應(yīng)用, 能利用手 機進(jìn)行上網(wǎng)沖浪, 3D游戲, 播放視頻等。即將來臨的第三代無線網(wǎng)絡(luò)將 會提供從每秒幾百 K bit 到幾兆 bit 不等的數(shù)據(jù)傳輸率, 從而將 會有足夠的帶寬來傳輸實時視頻信號和高質(zhì)量的音頻信號, 并允許下載大量的應(yīng)用和服務(wù)軟件。本文簡單介紹了流媒體的相關(guān)概念以及流媒體技術(shù)原理并實現(xiàn)了一個代碼主要使用SUN提供的JAVA媒體框架（JMF）包的功能來實現(xiàn)媒體播放功能的簡單的FMPlayer流媒體播放器的實例。

ABSTRACT

Along with technical changing with each new day, streaming media technology the development already to achieve from the quantitative change to the qualitative change critical moment, streaming media to will certainly to become the personal computing the network equipment mainstream, and has the extremely huge influence to people's daily life as well as the media dissemination. In order to develop a better player, the sellers have made the huge effort.
Technology and the rapid development of computer technology, makes it to the handheld device，applications with higher demands, people no longer satisfied with simple calls, send and receive text messages and other basic functions, but more is asking for multimedia applications, can use mobile phones for Internet surfing, 3D gaming, playing videos. The upcoming third-generation wireless networks will provide from a few hundred K bit to several megabytes per second bit rate data transmission range, which will have enough bandwidth to transmit high-quality real-time video signals and audio signals, and allow to download a large number of software applications and services. This article introduced simply streaming media the related concept as well as streaming media technology principle, and realized a code mainly to use JAVA which SUN provided a media frame (JMF) package of function to realize media broadcast function simple FMPlayer to streaming media player the example.

Key words：Streaming media；Streaming media player；Demand analysis；Flow chart
