Digital information recording/reproducing apparatus
A transmitting apparatus and method for transmitting a digital signal in which a time-base compressor compresses the digital signal, a bit compressor compresses the time-base compressed signal from the time-base so that a transmission rate of the time-base compressed signal from the time-base compressor is higher than a transmission rate of the bit-compressed signal from the bit-compressor, and a transmitter transmits the bit compressed signal.
1. A transmitting apparatus for transmitting a digital signal, comprising:
a time-base compressor which time-base compresses the digital signal at a first transmission rate;
a bit compressor which bit compresses the time-base compressed signal from the time-base compressor at a second transmission rate, the first transmission rate of the time-base compressed signal from the time-base compressor being higher than the second transmission rate of the bit-compressed signal from the bit-compressor; and
a transmitter which transmits the bit compressed signal.
2. A transmitting method for transmitting a digital signal, the method comprising the steps of:
time-base compressing the digital signal at a first transmission rate and providing a time-base compressed signal;
bit compressing the time-base compressed signal at a second transmission rate, the first transmission rate of the time-base compressed signal being higher than the second transmission rate of the bit-compressed signal; and
transmitting the bit compressed signal.
3. A transmitting apparatus for transmitting a digital signal, comprising:
a time-base compressor which time-base compresses the digital signal at a first transmission rate;
a bit compressor which bit compresses the time-base compressed signal from the time-base compressor at a second transmission rate, the first transmission rate of the time-base compressed signal from the time-base compressor being higher than the second transmission rate of the bit-compressed signal from the bit-compressor;
a parity adder which adds a parity signal to the bit compressed signal which parity signal enables correction of errors which occur in a transmission path; and
a transmitter which transmits the bit compressed signal having the parity signal added thereto.
