    # 遠(雲)端遊戲串流 ###### tags: `RD1` ## 簡介與原理 ![](https://i.imgur.com/G1HpolE.png) **傳統遊戲**我們需要將遊戲安裝到==指定的平台裝置==上才能夠遊玩,像是:XBOX、PS4、手機、桌機。如果有需要多人遊戲還需要將數據藉由網路傳遞到後端伺服器進行處理。由於不同遊戲可能對平台裝置有不同程度上的要求,玩家可能要==花費額外的金錢購買指定的平台裝置才能玩到想玩的遊戲,而且許多遊戲無法進行跨平台多人連線。== **雲端串流遊戲**的想法是只要把操作指令藉由網路傳給遠端的串流伺服器,由遠端的伺服器進行遊戲程式的操作遊玩並且把遊戲畫面藉由網路傳回給玩家。==這樣就可以大幅降低接觸遊戲的硬體門檻,更可以進行跨平台的遊戲遊玩。== **雲端串流遊戲操作的詳細過程如下:** ![](https://i.imgur.com/58Qm0wf.png) 1. 使用者使用操作手把或其他輸入設備透過網路傳送操作指令到串流遊戲平台。 2. 指令接收器收到指令後,再用此指令操作遊戲。 3. 遊戲收到指令後會改變畫面渲染。 4. 串流遊戲平台會捕捉渲染後的畫面,交由影音編碼器編碼。 5. 編碼後的畫面交由影音串流器透過網路回送到客戶端。 6. 透過解碼器解碼後顯示在玩家的裝置上。 ### 傳統遊戲痛點 1. 硬體設備的花費,常常由於硬體設備不足而放棄一款遊戲,而行動裝置上的遊戲由於效能不足,可以發揮的空間就小於主機跟PC了。 2. 許多不同平台上的遊戲無法進行多人連線遊玩。 3. 獨佔遊戲,可能某ㄧ款遊戲只在特定平台裝置上運行,就必須買這特定平台裝置。 ==獨佔遊戲就是指只有在特定平台才能玩的到遊戲== ### 串流遊戲解決以上痛點: 1. 不須在硬體裝置上花費額外金錢,只要網路速度夠快,有一個能夠解析1080p 60fps影片的裝置就能玩遊戲。 2. 跨平台遠端連線,由於遊戲都放在同一個雲端串流伺服器,多人跨平台遊玩就不是很大的問題。 3. 不須下載、安裝、更新遊戲,遊戲直接在雲端上,開了就能玩。 4. 由於遊戲程式都放在雲端串流伺服器,從根本上解決外掛、駭客跟盜版。 5. 串流遊戲平台玩家很多,遊戲廠商就可能會考慮在該串流遊戲平台開發遊戲,只要串流遊戲平台統一市場就不會有獨佔遊戲問題,甚至有可能終結遊戲主機。 ### 串流遊戲的實際問題: 1. 網路速度,串流遊戲雖然不吃硬體效能,但卻吃你的網路速度。玩一些卡牌遊戲或是不吃什麼操作的RPG遊戲可能不會有什麼影響,但賽車遊戲、射擊遊戲、音樂遊戲、動作遊戲這些很吃操作的類型的話,一點點的延遲就會造成遊戲體驗瞬間被摧毀。畫面、介面再好都沒用了。還有串流遊戲的網路串流品質不只牽扯到串流遊戲平台本身而已,還關係到你所處的地方網路基礎建設。 2. 不同的串流遊戲平台廠商可能會開發出不同的開發標準,根本上無法解決獨佔遊戲的問題。 ## 應用 過去的遠端串流概念比較像是能夠使用個人的其他裝置連到自己的電腦或是能夠玩遊戲的家用主機, 例如:==Steam的遠端暢玩==、==PS Remote Play==,這兩個服務能夠使用手機來遊玩遊戲,但是這兩個服務我自己覺得比較像是「遠端」遊戲串流,而比較不像後面介紹的==Google Stadia==、==Microsoft project Xcloud==、==Amazon Luna==等,後者比較接近是「雲端」遊戲串流,玩家可能是沒有自己的主機。 「雲端」遊戲串流,早在西元2000年時就由芬蘭的一間遊戲公司「G-cluster Global」實踐出來,但後來被日本的一間公司「Broadmedia」收購,之後提供日本國內遊戲串流服務。 ![](https://i.imgur.com/gRKHYTr.png =350x) ![](https://i.imgur.com/NLdgB0Q.jpg) ==Stadia==是由Google所推出的雲端遊戲串流服務,這一個服務算是近年最廣為人知的雲端遊戲串流平台,當初在發表會上展示令人相當驚嘆,雖然這樣的一個概念在過去已經存在,但是加上近年家用主機、電腦硬體的飛速發展,遊戲畫面提昇了不少,硬體購置成本也慢慢提升,加上近年各種串流平台相繼推出,音樂串流-Spotify、影片串流-Netflix,所以這樣的概念在近期提出,著實能夠造成不小的風潮。 目前看起來,Google Stadia 更像是一個標準的遊戲串流服務,而不像是亞馬遜或者微軟的狀況。 整體而言,Google Stadia 除了能夠跟 YouTube 遊戲直播做整合的這個特色以外,似乎看不出來有任何特別的商業策略。 目前收費方式有兩種,第一種是免費但需要購買遊戲,一種是付費訂閱。 能夠透過介紹影片提供的連結直接試玩。 ![](https://i.imgur.com/O19tJUu.gif) 能夠及時分享遊戲資訊 ![](https://i.imgur.com/mrSqbSv.gif) ![](https://i.imgur.com/JFeLbWn.png =350x) ![](https://i.imgur.com/y7lGkua.png) 對於微軟來說,下一個世代的遊戲戰場,其實是在遊戲訂閱制。所以微軟的策略,是要讓自己的遊戲訂閱制,在越多的平台上出現越好。即使微軟的次世代主機 Xbox Series X & Xbox Series S,都只是這個遊戲體驗中的一部分平台而已。對於微軟來說,他們希望你只要訂閱了微軟的遊戲訂閱服務 Xbox Game Pass,你就可以在任何時間任何地點用當時你所擁有的裝置來進行遊戲。 ![](https://i.imgur.com/bDL37qB.png =250x) ![](https://i.imgur.com/H0vn70A.jpg) 亞馬遜的 Prime 會員大戰略,就是要在 Prime 會員系統內,打造一個一站購足的完整服務。當消費者因為亞馬遜的電商免運服務,擁有了一組 Amazon Prime 帳號之後,他們日後會發現,這個帳號,裡面也有影片可看,也有音樂可聽,也有遊戲可玩,未來甚至還可以叫計程車。這些會員,未來會一整個活在亞馬遜的生態系之中,任何事情有亞馬遜就夠了 ## 參考資料 [Google推出串流遊戲服務Stadia,是怎麼運作呢? 真的有這麼厲害嗎? | 啾啾鞋](https://www.youtube.com/watch?v=ZqJz226VPUQ) [亞馬遜 Luna 參戰!三大科技巨頭的雲端遊戲大戰與串流遊戲的未來](https://www.inside.com.tw/article/21170-Stadia-xCloud-Luna) [綠茶幹話Time | 為什麼我現在不看好串流遊戲?來聊聊Google Stadia](https://www.youtube.com/watch?v=d_MWC2JXPrA) ---> 老舊 [Google's Stadia Announcement at GDC 2019 in Under 14 Minutes](https://www.youtube.com/watch?v=BeFnQrgtZ9k) [Project xCloud: Gaming with you at the center](https://www.youtube.com/watch?v=IzV_xrisMko) [Welcome to Amazon Luna – Everything You Need to Know](https://www.youtube.com/watch?v=726a6DwOitQ) [什麼是雲端串流遊戲?Google推出的Stadia即將改變遊戲生態!](https://medium.com/%E4%BD%91%E5%AF%B6%E7%9A%84%E8%81%B7%E5%A0%B4online/%E4%BB%80%E9%BA%BC%E6%98%AF%E9%9B%B2%E7%AB%AF%E4%B8%B2%E6%B5%81%E9%81%8A%E6%88%B2-google%E6%8E%A8%E5%87%BA%E7%9A%84stadia%E5%8D%B3%E5%B0%87%E6%94%B9%E8%AE%8A%E9%81%8A%E6%88%B2%E7%94%9F%E6%85%8B-af2033b06dd5) [【游戏杂谈12】谷歌Stadia实际体验测评。云游戏能够取代本地游戏吗?](https://www.youtube.com/watch?v=szHmRGrGEck)
