    • A method for converting a data stream in a first format into a data stream in a second format is provided. Each stream includes data packs in which video/audio data are stored and a control pack for use in a playback control of the stream. In the first format stream, address information, representing addresses of the data packs and not required while the stream is played back, is present and associated with the stream. In the second format stream, address information, representing addresses of the data packs and required while the stream is played back, is stored in the control pack. The method includes the steps of: acquiring the first format stream and its associated address information; generating a second control pack in the second format from a first control pack in the first format, the second control pack storing the address information acquired; and replacing the first control pack with the second control pack, thereby generating the second format stream from the first format stream.
    • 提供一种将第一格式的数据流转换为第二格式的数据流的方法。 每个流包括其中存储视频/音频数据的数据包和用于流的回放控制的控制包。 在第一格式流中,存在表示数据包的地址并且在流被重放时不需要的地址信息,并且与流相关联。 在第二格式流中,表示地址信息,表示数据包的地址,并且在播放流时所需的地址信息被存储在控制包中。 该方法包括以下步骤:获取第一格式流及其相关联的地址信息; 从所述第一格式的第一控制包生成第二格式的第二控制包,所述第二控制包存储获取的地址信息; 并且用第二控制包替换第一控制包,从而从第一格式流生成第二格式流。

    • A semiconductor memory card is provided with a transmitting and receiving circuit of a plurality of transmission systems such as a single-end signaling transmitting and receiving unit and a differential signaling transmitting and receiving unit. When power is turned on, each transmitting and receiving unit is turned on. When a command is provided from a host device, a command processing unit judges the transmission system provided in the host device, based on reception results of each circuit. Then, only a transmitting and receiving unit of the system identical to the transmission system used for transmission is turned on, and the subsequent data transmission is performed. Thus, the semiconductor memory card provided with a plurality of transmission systems performs transmission by simply identifying the transmission system provided in the host device.
    • 半导体存储卡设置有诸如单端信令发送和接收单元和差分信令发送和接收单元的多个传输系统的发送和接收电路。 当电源打开时,每个发送和接收单元都打开。 当从主机设备提供命令时,命令处理单元基于每个电路的接收结果来判断主机设备中提供的传输系统。 然后,只有与用于传输的传输系统相同的系统的发送和接收单元被接通,并且执行后续的数据传输。 因此,设置有多个传输系统的半导体存储卡通过简单地识别在主机设备中提供的传输系统来执行传输。

    • An automatic phase control apparatus for controlling the frequency of a sine wave produced from a variable frequency oscillator to be equal to that of the carrier wave of the extracted chrominance signal. A phase difference detector 4 detects a phase difference between the sine wave and the carrier wave. The detected phase difference is integrated to obtain an integrated value which is applied to the frequency oscillator for determining the oscillation frequency. A deviation detector is provided for detecting a deviation of the integrated value with respect to an expected frequency control data calculated by a calculator. When the deviation is greater than a predetermined range, the integrated value is replaced with the calculated data.
