Broadcast content distribution system, and distribution apparatus and broadcast reception terminal device for use in the system

A broadcast content distribution system, comprising:

• a distribution apparatus which:
• receives broadcast data over a broadcast network;
• demodulates the received broadcast data to generate broadcast transport stream packets;
• eliminates unnecessary packets from the broadcast transport stream packets to generate video-related data for a mobile terminal;
• acquires time information to be provided by analyzing the broadcast transport stream packets;
• generates program management information based on the provided time information;
• accumulates the video-related data and the program management information;
• accepts an individualized request to deliver video-related data of a designated program which has been sent through a network and impossible time information which indicates that data reception becomes impossible;
• determines whether or not data viewing becomes non-viewable by checking the impossible time information with the program management information;
• selects, when it is determined that data viewing becomes non-viewable, the whole video-related data of the requested program from accumulated video-related data;
• and
• distributes IP packets into which the selected whole video-related data is converted to a request origin;
• a mobile broadcast reception terminal device which:
• receives broadcast data over a broadcast network from a broadcast transmitting station and IP packets over a IP network;
• reproduces a program included in the broadcast data;
• monitors presence or absence of the data reception to generate the impossible time information;
• accumulates the generated impossible time information;
• accepts a request to play interrupted data;
• accesses the distribution apparatus over the IP network;
• transmits a request for distribution of the interrupted data and the accumulated impossible time information;
• receives the IP packets for the requested data;
• generates broadcast transport stream packets based on the received IP packets;
• and
• decodes the broadcast transport stream packets to reproduce the interrupted content from at least an interrupted point.
