Dear all: I know there are a lot of specs describing each si tables explicitly. But I find I really need some book or information to tell me what are these tables used for and when, how I need them. If someone knows any article or book introduces the whole relationships between different si tables, please let me know. thanks a lot, miloody _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
