Public Member Functions
bool	Load (string file_name, int mode)
	This API is to load program data from XML file, if the operation mode selected is XML to Binary. Otherwise it will load program data from cache file. More...

bool	GenerateSICache (string sidbFileName)
	Generates binary SI cache from the XML file. More...

bool	GenerateSICache (string sidbFileName, string snsdbFileName)
	Generate both binary SI cache and binary SNS cache from the XML file. More...

bool	GenerateXML (string sixmlFileName)
	Function to generate XML file(sidb.xml). More...

void	DumpChannelMap ()
	Dump channel map information from binary SI cache to console.

Protected Attributes
list< ProgramDetails >	m_program_list

int	numOfServices

Private Member Functions
bool	load_xml_file (string xml_file)
	This function loads an input xml file into memory, it does the formatting related validations and parses the attributes. More...

int	xml_parse_attributes (xmlNodePtr parent)
	This API parses the program id, source id, modulation, frequency information from the XML. More...

void	init_mpeg2_crc (void)
	Initializes the CRC check.

uint32_t	calc_mpeg2_crc (uint8_t *data, uint32_t len)
	Function to calculate Cyclic Redundancy Check(CRC) value. CRC is used to find the accidental changes happened to raw data. Here is the CRC flow works here. More...

void	init_si_entry (siTableEntry *si_entry)
	Internal Method to initialize service entries to default values init_si_entry() More...

bool	parse_program_details (siTableEntry **si_entry_head, uint32_t frequency[], uint32_t modulation[], int &f_index, int &m_index)
	This API loads the program data from binary cache file. More...

bool	cache_si_data (string sidbFileName)
	This API write the program details like modulation, frequency, program number, VCN information to SI cache file. More...

bool	cache_sns_data (string snsdbFileName)

bool	write_crc_for_si_cache (string sidbFileName)
	This API finds the CRC value and writes at the end of SI cache file. More...

bool	write_crc_for_si_and_sns_cache (string sidbFileName, string snsdbFileName)
	This finds the CRC and write it at the end of SI and SNS cache files. More...

unsigned int	get_file_size (const char *location)
	The si_get_file_size() function will get the size of the specified file. More...

bool	load_si_data (string sidbFileName)
	This API function loads the program data from binary cache file. More...
