System Messages
System messages are used internally to command objects to perform certain operations. The definition of these messages is determined by RTPEG-32, and RTPEG-32 objects understand what to do when they receive various system messages.
In addition to defining custom messages, it is very common to want to receive and process the system messages that are generated internally. This is sometimes called intercepting a message, because it catches a message that RTPEG-32 has sent to an object and change the interpretation of the message, or even cause the object to ignore the message entirely.
