FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.

7 Structure of the PMT in the interactive BIFS stream
7.1 General
The structure of the PMT used in the interactive BIFS broadcasting is different from that used
in the basic audio/video broadcasting, which causes the malfunction of terminals.
Figure 2 shows the structure of the PMT used in the interactive BIFS broadcasting in
comparison to that used in the basic audio/video broadcasting (the order of each ESD may be
set up arbitrarily).

Figure 2 – Changes of the PMT structure in the interactive BIFS broadcasting
7.2 Structure of the PMT in the basic audio/video broadcasting
The IOD including an ES_Descriptor for each of the OD and the BIFS shall be transmitted,
because the OD and the BIFS are transmitted by one ES respectively.
The ESs constituting a broadcasting program are OD, BIFS, audio and video. Four PIDs and
the SL_Descriptor related to OD, BIFS, audio and video shall be transmitted.
7.3 Structure of the PMT in the interactive BIFS stream
The IOD including ES_Descriptors for more than two of the OD and the BIFS shall be
transmitted, because the OD and the BIFS for interactive BIFS broadcasting are transmitted
by multiple ESs.
Multiple PIDs and the SL_Descriptors related to several OD, BIFS, audio, video and several
JPEG/JPEG-2000/PNG still images that are the ESs comprising the broadcasting program
shall be transmitted.
8 Cases for terminal malfunction and solutions
8.1 Case 1: No interpretation on the IOD
8.1.1 Problem
The IOD is not interpreted on the assumption that only the audio/video content has been
transmitted.
When multiple OD streams exist in the IOD, it may not be possible to distinguish OD streams
related to audio/video content.
In this case, the problem occurs that the value of PID related to the audio/video contents
cannot be obtained.
– 12 – 62516-2 © IEC:2011
8.1.2 Solution
The terminal shall execute interpretation on IOD/OD by all possible means for exact playback
of the audio/video contents, even if the terminal is only able to interpret the audio/video
contents, as shown in Figure 3.

8.2 Case 2: Size of the IOD confined within a specific limit
8.2.1 Problem
It is not considered that the OD/BIFS data shall be transmitted after they have been divided
into multiple streams.
In this case, the IOD can increase in size and errors may occur as a result of it.
8.2.2 Solution
Irrespective of the capability of a terminal to interpret various kinds of audio/video contents,
the terminal shall be capable to interpret normally IOD/OD for exaxt playback of the
audio/video contents, as shown in Figure 4.

8.3 Case 3: On the assumption that the PMT is transmitted in one TS packet
8.3.1 Problem
The PMT is interpreted on the assumption that the number of ESs used in composition of
contents is not big.
Errors can occur when the PMT is transmitted in two or more TS packets when the amount of
the OD/BIFS data increases and when JPEG/JPEG-2000/PNG still images are included.
8.3.2 Solution
It is necessary that the PMT comprised of two or more TS packets shall be interpreted
accurately, as shown in Figure 5.

8.4 Case 4: Existence of two or more OD streams in the IOD
8.4.1 Problem
It is assumed that only one OD stream is described in the IOD.
An error can occur when there are descriptions of two or more OD streams in the IOD.
8.4.2 Solution
An accurate interpretation on the IOD shall be executed, as shown in Figure 6.

NOTE 1 The terminal without the support of the interactive service should be modified in order to accurately
process the OD stream for audio/video.
NOTE 2 Malfunction cases in the terminal are not the result from the BIFS standard itself. It is rather the result of
improper processing of the BIFS information in the MPEG-2 system layer. Terminals should be supplemented to
solve those errors.

10 Example of initiation procedure for audio/video service in an interactive BIFS
stream
This clause shows an example of initiation procedure for audio/video services in the
interactive BIFS streams in Figure 7.
The initiation procedure for audio/video service in the interactive BIFS streams is the following:
㉧ The PAT with PID = 0x0000 shall be obtained from TS packets in the MPEG-2 TS and
interpreted. Then a program number and PMT_PID corresponding to that number shall be
identified. In this case, only one PMT is referenced in the PAT.
① Search for a PMT in the TS according to PMT_PID obtained above.
st
② Obtain and interpret the IOD in the 1 _descriptor_loop of the PMT. (More than one
ES_Descriptor exist in the IOD. Search for the basic ES Descriptor for the audio/video
broadcast among several ES_Descriptors by referring to stream_type and
objectTypeIndication field values).
③ Obtain and interpret the elementary_PID corresponding to ES comprising the program and
the stream_type representing transmission mode respectively.
④ to ⑤ Obtain and interpret the BIFS_1 for audio/video. (It is not necessary to interpret the
BIFS_1 only for the audio/video service. For interactive service, the BIFS_1 and BIFS_2 shall
be obtained and interpreted).
⑥ to ⑦ Obtain and interpret the OD_1 for the audio/video. (For interactive service, the
BIFS_1 and BIFS_2 shall be obtained and interpreted).
⑧ Obtain the audio stream
⑨ Obtain the video stream

11 Example of the stream dependency scheme for interactive BIFS stream of
broadcasting stations
There are several methods for composition of interactive BIFS streams. Establishment forms
of the stream dependency for streams that broadcasting stations have adopted are different.
This difference may be unified in the future. Figure 8 shows the comparison of stream
dependency establishment forms between two broadcasting stations.

To prevent the malfunction of terminals without processing capability of the interactive BIFS
stream, it is required to maintain the function of extracting and interpreting data related to the
audio/video only.
The basic ES_Descriptors for the audio/video broadcast shall be searched for among several
ES_Descriptors existing in IOD and OD by referring to stream_type and objectTypeIndication
field values.
Even in terminals without processing capability of interactive BIFS stream, the malfunction will
not occur if the IOD and the OD are accurately interpreted.
