Abstract

The method to transmit TV-Anytime service on DVB network comprises steps: dividing the TV-Anytime into data container and its initialization information; packaging said information in initialization descriptor of TV-Anytime; according to basic flow of carried count container and other information, generating TP descriptor based on transmission mechanism; storing said initialization descriptor and TP descriptor into subtable of SDT or user new-built table, and transmitting to receiver with network; and transmitting the said data container to receiver by said transmission mechanism.

Description

technical field [0001] The present invention relates to a method of transmitting TV Anytime service over a digital video broadcasting network. In particular, a method capable of combining television with the Internet to realize instant program on demand.
