Abstract
A low bit rate coding apparatus is made up of: a circuit for storing at least a television input signal of a single screen; a circuit for sub-sampling the stored television input signal at a predetermined time period to read out the sub-sampled television input signal; a circuit for coding the read television input signal at a low bit rate; and a circuit in which, after the television input signal of a single screen has been sub-sampled and read out, and the low bit rate coding operation has been carried out, the television input signal is again read out at a different sub-sampling position and low-bit-rate coded.
