RECTIFICATIF TECHNIQUE 3
Technical Corrigendum 3 to ISO/IEC 14496-3:2009 was prepared by Joint Technical Committee
ISO/IEC JTC 1, Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and
hypermedia information.

In 12.3 Payloads for the audio object, replace Table 12.2:
Syntax No. of bits Mnemonics
lle_element()
{
 for (ch=0;ch   if (is_channel_pair(ch)) {
  lle_channel_pair_element();
  ch += 2;
  } else {
  lle_single channel_element();
  ch++;
  }
 }
}

In 12.3 Payloads for the audio object, add at the end:
Table 12.9 — Syntax of lle_lfe_channel_element
Syntax No. of bits Mnemonics
lle_lfe_channel_element()
{
lle_individual_channel_stream(1);
}


In 12.3 Payloads for the audio object, add at the end:

The functions getNrOfElements(channelConfiguration) and getNextElement(el, channelConfiguration) are
defined as follows:

UINT32 getNrOfElements(channelConfiguration)
{
 UINT32 NrOfFixChannelConfigElements[7] = { 1, 1, 2, 3, 3, 4, 5 };

 if(channelConfiguration == 0){
  return num_front_channel_elements + num_side_channel_elements +
      num_back_channel_elements + num_lfe_channel_elements;
 } else {
  return NrOfFixChannelConfigElements[channelConfiguration - 1];
