    • A method and apparatus by which a reception device of a communication system can sense and compensate for an error of a program clock reference (PCR), and can sense and compensate for bit rate variation of transmission data in a transmitted MPEG-2 TS. The method and apparatus compensates for a PCR jitter, or a change in a data bit rate, which may occur in processing an MPEG-2 TS in a reception device of the MPEG-2 TS transmission system, thereby preventing the deterioration of image quality due to the jitter or loss of an input MPEG-2 TS data. The apparatus includes a PAT sensing unit for sensing a PAT from a received MPEG-2 TS, a PMT sensing unit for sensing a PMT based on information provided from the PAT sensing unit, a PCR PID unit for sensing a PCR PID based on information provided from the PMT sensing unit and a PCR data unit for outputting a PCR data based on information provided from the PMT sensing unit and PID information provided from the PCR PID unit. The apparatus also includes a PCR comparison/compensation unit receiving the PCR data from the PCR data unit, comparing the received PCR data with a pre-stored PCR data, and compensating for the pre-stored PCR data, and a data rate comparison/compensation unit for receiving data rate information from the PCR data unit, comparing the received data rate with a pre-stored data rate, and compensating for the pre-stored data rate.

    • A method for converting data includes matching dynamic elements by repeatedly selecting a portion of unit elements among N unit elements according to data and a circulation direction. An existence of a tone generation possibility is determined by comparing a present pointer position with a previous pointer position and by comparing present data with previous data. At least one of the present pointer position and the circulation direction is changed based on the existence of the tone generation possibility. The present pointer position and the present data are stored or the changed pointer position and the present data are stored. Unit elements are sequentially selected by the present data from the stored pointer position in the circulation direction or the changed circulation direction. The present pointer position is moved by the present data in the circulation direction or the changed circulation direction.
    • 用于转换数据的方法包括通过根据数据和循环方向重复地选择N个单元中的单位元素的一部分来匹配动态元素。 通过将当前指针位置与先前的指针位置进行比较并通过将当前数据与先前数据进行比较来确定音调生成可能性的存在。 本指针位置和循环方向中的至少一个基于音调生成可能性的存在而改变。 存储当前指针位置和当前数据,或存储改变的指针位置和当前数据。 通过来自循环方向或改变的循环方向上存储的指示器位置的当前数据顺序地选择单位元素。 当前数据在循环方向或改变的循环方向上移动当前指针位置。
