Historically, these were defined by macros which built a Program Control Table (PCT), but are nowadays defined in TRANSACTION definitions within the resource definition on-line (RDO) database.
At the same time, this paper also improves the process of RDO in the macroblock layer. Based on the prediction bits of the macroblock, the Lagrange coefficient has been modified adaptively.
從歷史上看，通過巨集命令來定義事務id，這些巨集命令建立程式控制表(Program ControlTable,PCT)，但是目前是在線上資源定義資料庫(resourcedefinition on - line,RDO)內部的TRANSACTION定義中定義事務id。
