Data transmitting method and system

摘要

A system and method for transmitting, for example, ATRAC data consisting of a plurality of sound groups or record elements (basic elements) in an MPEG stream is disclosed. The ATRAC data is placed in transport stream (TS) packets such that the basic elements of the ATRAC data are kept intact during transmission and errors in transmission are detected. The ATRAC data is transmitted in packetized elementary stream (PES) packets with an amount of ATRAC data (159 bytes) being placed in each TS packet such that an integer number (eight) of TS packets is placed in each PES packet. As a result, an integer number (three) of sound frames of ATRAC data is transmitted in each PES packet. A checksum code also is included in each TS packet to detect errors in the data's transmission.
