Abstract:
A data sequence generator for generating a data sequence to be transmitted through a transmission channel by generating according to input of information data a variable length frame having a first storage area storing variable length information data inputted from the outside, a second storage area storing specific information for establishing a frame synchronization, a third storage area storing header information necessary for decoding said information data and establishing said frame synchronization and a fourth storage area storing frame length information indicating a frame length, said data sequence generator comprising;a header information error detection encoding means for obtaining header information error-detection-encoded data by applying an error detection encoding process to said header information, a header information storing means for storing said header information error-detection-encoded data into said third storage area corresponding to said header information, and an inserting means for inserting said header information error-detection-encoded data in an insertion position which is a position to be determined from the timing of said frame synchronization in said data sequence and is separated from said third storage area.
