with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.

61883-4 ” IEC:2004(E) – 5 –
4 Construction of IEEE 1394 packet
4.1 Structure of the MPEG2-TS data stream
The length of the source packet is 192 bytes (see Figure 1). The source packet consists of
one MPEG2-TSP with a length of 188 bytes and a source packet header of 4 bytes. The
source packet header contains a time stamp.
MPEG2-TS packets shall comply with ISO/IEC 13818 series.
4.2 Packetization of source packet of the MPEG2-TS data stream
A source packet is split into 8 data blocks with a length of 6 quadlets. Zero or more data
blocks are packed in an IEEE 1394 isochronous packet. A receiver of the isochronous packets
shall collect the data blocks of one source packet and combine them in order to reconstruct
the source packet before sending this source packet to the application. There are restrictions
on the transmission of fractions (see 5.2).
Active transmitters shall send an isochronous packet in every cycle. If not enough data is
available to transmit in the isochronous packet, then an empty packet shall be transmitted.
4.3 Time stamp
The time stamp in the source packet header is used by isochronous data receivers for
reconstructing a correct timing of the TSPs at their output. The time stamp indicates the
intended delivery time of the first bit/byte of the TSP from the receiver output to the transport
stream target decoder. The time stamp represents the 25 bits of the IEEE 1394 CYCLE_TIME
register (CTR) at the moment the first bit/byte of the TSP arrives from the application, plus
some offset. The offset is equal to the constant overall delay of the TSP between the moment
of arriving (of the first bit) and the moment the TSP (first bit) is delivered by the receiver to the
application.
5 CIP header
5.1 Structure of CIP header
The structure of the CIP header (see Figure 2) for the MPEG2-TS is compliant with the two
quadlet CIP header format explained in IEC 61883-1, 6.2.1. The static values of the CIP
header components are as follows.
SID . (depends on configuration)
DBS 00000110 (6 quadlets)
FN 112 (8 data blocks in one source packet)
QPC 000 (no padding)
SPH 1 (source packet header is present)
DBC 0 . 255 (see 5.2)
FMT 100000 (format type of MPEG2-TS)
FDF . (see 5.3)
– 6 – 61883-4 ” IEC:2004(E)
5.2 DBC values
The first data block of a source packet (data block containing the source packet header)
corresponds to a DBC value from which the three LSBs are ‘000’.
An isochronous packet contains 0, 1, 2 or 4 data blocks or an integer number of source
packets.
Where the isochronous packet contains
 one data block, then the DBC value increments with 1;
 two data blocks, then the DBC value is a multiple of 2, the LSB is ‘0’;
 four data blocks, then the DBC value is a multiple of 4, the two LSBs are ’00’.
Where the isochronous packet contains n source packets (n is an integer) then the DBC value
is a multiple of 8. The three LSBs are ‘000’.
5.3 FDF area
The structure of the FDF area is shown in Figure 3. The definitions of the fields are as follows:
 TSF (time shift flag) indicates a time-shifted data stream:
0 = the stream is not time-shifted.
1 = the stream is time-shifted.
 Res: reserved for future extension and shall be zeros.
6 Transmission of isochronous packets
6.1 Steps in transmission
An MPEG2-TS consists of TSPs with a length of 188 bytes. In Figure 4, an example is given
of a TS which consists of several programmes. Very often only one or a few programs have to
be transmitted. If a programme selection is carried out, then only those TSPs from that
particular TS are transmitted. In this situation, the occupied bandwidth on the 1394 interface
can be reduced. Reduction of the bit rate is carried out in a smoothing buffer. As a result of
the smoothing operation, the TSPs will be shifted in time.
The TSPs at the output of the smoothing buffer are transmitted over the interface. During
transmission this interface will introduce some jitter on the arrival time of the TSPs in the
receiver.
In the MPEG2-TS there are strong requirements on the timing of the TSPs. The jitter
introduced by the smoothing buffer and the transmitter of the interface shall be compensated.
To do this, a time stamp is added to the TSP at the moment it arrives at the input of the
smoothing buffer or, if smoothing is not applied, at the input of the digital interface. The
receiver of the interface contains a receiver buffer. In this receiver buffer, the jitter introduced
is compensated.

The time stamp in the transmitted source packet header shall point to a value in future. If for
some reason the delay in the tr
