A method, device and system for requesting and transmitting a service are provided, which belong to the communications field. The method includes: a bidirectional device of the head end receives a service request transmitted by a terminal device and obtains the corresponding service (101); the bidirectional device of the head end judges whether the service can be distributed by an unidirectional device of the head end (102); if yes, the bidirectional device of the head end routes the service to the unidirectional device of the head end, so that the unidirectional device of the head end distributes the service to the terminal device (103); otherwise, the bidirectional device of the head end distributes the service to the terminal device (104). By dispensing with the process of a service server in the prior art in the present invention, the bidirectional device of the head end obtains the service from the service server and judges whether the service data is distributed by the unidirectional device of the head end or is interacted through a bidirectional network (such as Internet Protocol (IP) network), so as to distribute, through utilizing high-bandwidth unidirectional network, heavy traffic IP broadcast and multicast data which originally need to be distributed by the bidirectional network, and therefore the bandwidth pressure on the bidirectional network is mitigated.
