A study on implementation of table generating system for data broadcasting based on ACAP [advanced common application platform]

Digital broadcasting has the advantage of better quality images and sound, more consumer choice, electronic program guides, and so on. Moreover consumers are able to enjoy services actively. The implemented system generates the PSIP, PSI, and AIT stream for terrestrial data broadcasting. This system is composed of two parts. One part is the streaming controller. It makes metadata for PSIP, PSI and AIT according to pre-defined XML schema. The other part is the table generator. It generates a transport stream packet from the transmitted metadata. The implemented system receives XML documents. Therefore, it is available in any broadcasting system, if the user converts the metadata.
