Title: Method and system for changing received streaming contents channel
Inventor: STAHL THOMAS ANTHONY
IPC: H04L49/9023
Filed: 2002-09-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide a system and method for changing received streaming contents channel by which channels can be changed instantaneously and, at the same time, jitters can be eliminated.  <P>SOLUTION: In the system and method, a first contents stream carrying contents channel signals is received by means of a buffer. The first contents stream first loads the buffer by carrying the contents channel signals at a speed which is considerably faster than the reproducing speed of streaming contents. The buffer switches the reception of the contents channel signals from the first contents stream to a second contents stream. The rate (speed) of the second contents stream is almost equal to the reproducing rate (speed) of the streaming contents. This switching generally occurs when contents channel signals of a prescribed threshold are buffered.  <P>COPYRIGHT: (C)2003,JPO
