摘要

A method and apparatus for transmitting and receiving data. The method and apparatus previously determines a validity of a data transmission path for transmitting a stream from a source device to a sink device. The validity of the transmission path is verified by checking and securing the data transmission path, thereby executing a streaming service based on the validity.
