Title:
符号化された形式と符号化されない形式のディジタル情報信号を交互に伝送する伝送装置
Document Type and Number:
Japanese Patent JP4248026
Kind Code:
B2
Abstract:
A transmitter is disclosed for transmitting a digital information signal via a transmission medium. The digital information signal can be divided into one or more sub-signals. Each sub-signal is transmitted as a non-encoded or as an encoded signal. In which way the sub-signal is transmitted depends on the compression that can be achieved by the encoder. If the compression is low the sub-signal is transmitted in non-encoded form. For the receiver an identification is added to the composite signal to be transmitted. A first component of the identification signal indicates if one or more sub-signals are transmitted in encoded form. A second component of the identification signal indicates for each sub-signal whether it appears in encoded or non-encoded form in the composite signal. The invention provides a composite signal with a minimal number of bits.
