Information embedded method and system

An information embedded system comprising:

• a broadcast source delivering broadcast signals through a unidirectional transmission medium during a second time period;
• and
• a broadcast signal receiver comprising a storage device, the broadcast signal receiver receiving the broadcast signals through the unidirectional transmission medium, receiving and storing a plurality of information-push files in the storage device of the broadcast signal receiver during a first time period prior to the second time period, selecting one of the information-push files according to a predetermined rule, and combining the broadcast signals and information content of the selected information-push file to form an information embedded program.

A broadcast source of an information embedded system, the broadcast source comprising a broadcast signal transmitter for delivering broadcast signals and a plurality of information-push files to a broadcast signal receiver through a unidirectional transmission medium, wherein

• the information-push files are transmitted to the broadcast signal receiver through an idle channel or a dedicated channel of the unidirectional transmission medium during a first time period, and the broadcast signals are transmitted to the broadcast signal receiver through a broadcast channel of the unidirectional transmission medium during a second time period posterior to the first time period, and
• the broadcast signals comprise insertion splice points or display position for inserting information content of one of the information-push files into broadcast content of the broadcast signals.
