32 * HEADER SUMMARY : Mpeg2 TS mapping module public interface
33 *
34 * Refer to IEC 61883-4 for details of the "source packet" structure.
35 *
36 * This mapping module module as a talker requires an interface module to push
37 * one source packet of 192 octets into the media queue along with a media queue
38 * time value when the first data block of the source packet was obtained.
39 * There is no need to place the timestamp witin the source packet header,
40 * this will be done within the mapping module were the max transit time will be
41 * added. The mapping module may bundle multiple source packets into one avtp packet
42 * before sending it.
43 *
44 * This mapping module module as a listener will parse source packets from the
45 * avtp packet and place each source packet of 192 octets into the media queue along
46 * with the correct time stamp from the source packet header. The interface module
47 * will pull each source packet from the media queue and present has needed.
48 *
49 * The protocol_specific_header, CIP header and the mpeg2 ts source packet header are
50 * all taken care of in the mapping module.
