The invention relates to a
system of implementing
video on demand and review of a unidirectional set-top box through a mobile intelligent terminal. In the
system, both-way communication between the mobile intelligent terminal and an interactive portal sub-
system is carried out through
mobile Internet, a
mobile communication network and a firewall, both-way communication between the interactive portal sub-system and a streaming
media content storage and distribution sub-system is carried out, the streaming
media content storage and distribution sub-system pushes flow to a streaming media
base station sub-system, after a plug flow
signal is changed into a
radio frequency signal by the streaming media
base station sub-system, the plug flow
signal is transmitted to a
coaxial cable network of a
cable television, the unidirectional set-top box and a television terminal, an available channel number is transmitted to an intelligent terminal interface by a frequency point
resource management sub-system, when the television terminal is switched to the available channel number, all kinds of reception operations can be implemented through the intelligent terminal. According to the system, limited frequency points and
broadband resources are reasonably utilized, the unique interactive portal sub-system is capable of skilfully making the mobile intelligent terminal and a
digital television form an organic whole, so that
video on demand and review can be implemented under the condition of the unidirectional set-top box, and sub-
millisecond demand response is achieved.
