商品描述

Digital Video Concepts, Methods, and Metrics: Quality, Compression, Performance, and Power Trade-off Analysis is a concise reference for professionals in a wide range of applications and vocations. It focuses on giving the reader mastery over the concepts, methods and metrics of digital video coding, so that readers have sufficient understanding to choose and tune coding parameters for optimum results that would suit their particular needs for quality, compression, speed and power.

The practical aspects are many: Uploading video to the Internet is only the beginning of a trend where a consumer controls video quality and speed by trading off various other factors. Open source and proprietary applications such as video e-mail, private party content generation, editing and archiving, and cloud asset management would give further control to the end-user.

Digital video is frequently compressed and coded for easier storage and transmission. This process involves visual quality loss due to typical data compression techniques and requires use of high performance computing systems. A careful balance between the amount of compression, the visual quality loss and the coding speed is necessary to keep the total system cost down, while delivering a good user experience for various video applications. At the same time, power consumption optimizations are also essential to get the job done on inexpensive consumer platforms.

Trade-offs can be made among these factors, and relevant considerations are particularly important in resource-constrained low power devices. To better understand the trade-offs this book discusses a comprehensive set of engineering principles, strategies, methods and metrics. It also exposes readers to approaches on how to differentiate and rank video coding solutions.

What you’ll learn

  • Cost-benefit analysis of compression techniques
  • Video quality metrics evaluation
  • Performance and power optimization and measurement
  • Trade-off analysis among power, performance, and visual quality
  • Emerging uses and applications of video technologies

    Who this book is for

    This book is for anyone involved in designing, developing, validating, deploying, and reviewing systems and applications that deal with digital video. For example, software and hardware engineers, system architects, technical program and product managers, support and sales engineers, system integrators, technology journalists and video professionals working in the multimedia and telecommunication industries, researchers and graduate students, or even a tech-savvy user who posts a YouTube video would find this book a useful reference.

    商品描述(中文翻譯)

    《數位影片概念、方法與指標:品質、壓縮、效能與功耗權衡分析》是一本針對各種應用和職業的專業人士的簡明參考書。它專注於讓讀者掌握數位影片編碼的概念、方法和指標,使讀者能夠充分理解以選擇和調整編碼參數,以獲得適合其特定需求的最佳結果,包括品質、壓縮、速度和功耗。

    實際方面有很多:將影片上傳到互聯網僅僅是消費者控制影片品質和速度的趨勢的開始,這需要在各種其他因素之間進行權衡。開源和專有應用程式,如影片電子郵件、私人派對內容生成、編輯和存檔,以及雲端資產管理,將進一步賦予最終用戶更多控制權。

    數位影片經常被壓縮和編碼,以便於儲存和傳輸。這一過程涉及由於典型數據壓縮技術而導致的視覺品質損失,並需要使用高效能計算系統。必須在壓縮量、視覺品質損失和編碼速度之間取得小心的平衡,以降低整體系統成本,同時為各種影片應用提供良好的用戶體驗。與此同時,功耗優化對於在廉價消費者平台上完成任務也是至關重要的。

    這些因素之間可以進行權衡,相關考量在資源受限的低功耗設備中特別重要。為了更好地理解這些權衡,本書討論了一套全面的工程原則、策略、方法和指標。它還向讀者介紹了如何區分和排名影片編碼解決方案的方法。

    您將學到的內容:
    - 壓縮技術的成本效益分析
    - 影片品質指標評估
    - 效能與功耗的優化與測量
    - 功耗、效能與視覺品質之間的權衡分析
    - 新興的影片技術使用與應用

    本書適合對象:
    本書適合任何參與設計、開發、驗證、部署和審查處理數位影片的系統和應用的人士。例如,軟體和硬體工程師、系統架構師、技術計畫和產品經理、支援和銷售工程師、系統整合商、科技記者以及在多媒體和電信行業工作的影片專業人士、研究人員和研究生,甚至是發佈YouTube影片的科技愛好者,都會發現本書是一本有用的參考資料。
