Abstract:
A buffer apparatus with a data insertion control function, comprising:a plurality of buffers for holding different types of data which are to be inserted into a predetermined transmission medium and are equal in insertion priority; and a data insertion controller for controlling the data insertion order in which the different types of data are to be inserted into said transmission medium by controlling a read process order in which the different types of data are to be read from said buffers based on a write process order in which the different types of data have been stored in said buffers, wherein said data insertion controller generates link data about the write process order during a write process, and performs a read process of the different types of data according to said link data, to thereby read the different types of data from said buffers in the write process; and said buffer apparatus further comprising a plurality of first link memories corresponding one to each of said plurality of buffers and each having the same address configuration as that of the corresponding buffer, wherein said data insertion controller stores a type of the data which has currently been written, in said first link memory at the same address as that of the corresponding buffer at which the previous write process was performed, to thereby generate said link data.
