  4. Vlc is a solution of integrated supply chain information. the realization of vlc can reduce social cost of logistics operation and improve the benefit of enterprise

    實踐上，虛擬物流企業的實施具有重要的經濟意義，可以降低社會物流運作成本，提高企業的經濟效益。
  5. Firstly, we introduce implement detail of every part of h. 263, such as dct, vlc and so on

    首先介紹了h . 263視頻編碼器的各個重要部分如dct 、可變長編碼等的實現細節。
  6. Vlc is a integrated information system in high level and a hard task to implement, so it ' s necessary to establish scientific mechanism to ensure the successful implementation and abate or eliminate the project risk

    虛擬物流企業是一個高層次的集成信息系統，其實施是一項巨大的工程。必須建立科學的項目管理機制以保證項目的實施，減少或防止項目的風險。

  8. This paper first research on main technologies used by avs standard, which include prediction, transform, quantization, in - loop filter, and entropy encoding, and then focus on the 2d - vlc entropy coder of avs, which is context - based adaptive coder. this encoder operates on run - level pair, and it uses the type of current block and value of current coefficients to switch vlc code - table. these tables are designed according to the distribution of transformed coefficients, and this way is much better than using only one table to code all residual coefficients in one 8x8 block

    本文首先詳細研究了avs標準的核心技術，包括預測編碼、變換量化、環路濾波器以及掃描和熵編碼等，之後重點研究了avs標準中使用的基於上下文的2d - vlc變長編碼方法，這種方法編碼的是（ run ， level ）數對，同時根據當前編碼塊的類型和殘差系數這兩種上下文信息來切換碼表，這些碼表是預先根據變換系數在不同位置的分佈信息設計好的，這樣要比只使用一個變長碼表來編碼塊內所有位置上的殘差系數的壓縮效果要好得多。
