Title: Image transmission method for multimedia communication
Inventor: ONISHI TAKESHI
IPC: H04N19/65
Filed: 2001-12-03
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that a multimedia system for transmitting real time data requires a transmission process and a transmission efficiency as high as possible.  <P>SOLUTION: In a data transmitting section 2 in transmitting MPEG 4 data, a 16-bit CRC (cyclic redundancy check) adding circuit 5 adds a 16-bit CRC code to image data from an image CODEC 6 according to ITU-T Recommendation H. 223 in order to detect bit errors. In a data receiving section 11, a 16-bit CRC checking circuit 14 detects the bit errors in the image data. However, since even the data containing bit errors can be restored by an RVLC function of the CODEC 6, there is no need to detect bit errors according to H. 223. The transmission speed and transmission efficiency can be improved by not using the 16-bit CRC code in that case.  <P>COPYRIGHT: (C)2003,JPO
