    • A method for converting data received in either a Level A or Level B SMPTE 425M compliant format into either a Level B or a Level A compliant format, respectively, includes receiving and processing data in one of a Level A or a Level B SMPTE 425M compliant format. Inputting the received Level A formatted data into a storage device and reading out Level B formatted data at an output of the storage device, or inputting Level B formatted data into the storage device and reading out Level A formatted data at an output of the storage device. Back-end circuitry further processes the Level A formatted data when Level B formatted data is received or further processes the Level B formatted data when Level A formatted data is received. The storage device is operated as a line multiplexer to convert data in a Level B format to data in a Level A format and is operated as a line demultiplexer to convert data in a Level A format to data in a Level B format. Receivers and transmitters capable of performing the method are also disclosed.
    • 用于将以A级或B级SMPTE 425M兼容格式接收的数据分别转换为B级或A级兼容格式的方法包括接收和处理符合A级或B级SMPTE 425M级别的数据 格式。 将接收到的A级格式的数据输入存储装置,并在存储装置的输出端读出B级格式的数据,或者将B级格式的数据输入存储装置,并在存储装置的输出端读出A级格式的数据 。 当接收到B级格式的数据时,后端电路进一步处理A级格式的数据,或者当接收到A级格式的数据时进一步处理B级格式的数据。 存储设备作为线路多路复用器操作,以将B级格式的数据转换为A级格式的数据,并作为线路解复用器进行操作,以将A级格式的数据转换为B级格式的数据。 还公开了能够执行该方法的接收机和发射机。
