Hepl required regarding the PAT table

["Vinay S." <vinay@innoviti.com>]

hi

 I m a newbie to DVB-RCS.While trying to get the Program map PIDs, for the
different programs,from the PAT table,
a variable N is presented in the standard, saying that so many program
channels are present.But, I have not found any place/hint
indicating what this variable n might be? The exact context is given
below.(marked by the Arrow)

program_association_table
program_association_section()
{
	table_id 8 uimsbf
	section_syntax_indicator 1 bslbf
	'0' 1 bslbf
	reserved 2 bslbf
	section_length 12 uimsbf
	transport_stream_id 16 uimsbf
	reserved 2 bslbf
	version_number 5 uimsbf
	current_next_indicator 1 bslbf
	section_number 8 uimsbf
	last_section_number 8 uimsbf

	for (i = 0; i < N; i++)  -------------------->what is the value of N?
	{
		program_number 16 uimsbf
		reserved 3 bslbf
		if (program_number = = '0')
		{
			network_PID 13 uimsbf
		}
		else
		{
		program_map_PID 13 uimsbf
		}
	}
CRC_32 32 rpchof
}


with warm regards,
