Abstract: The present invention relates to a transmission apparatus and method, a reception apparatus and method, and a transmission/reception system whereby contents as occasion requires can be acquired. A server (11) generates a PDI-Q representing a question about a user's taste of a client (12), and transmits, to the client (12), the PDI-Q and a provider-side PDI-BA expressed by use of a bitmap index and representing an answer, which is established by a provider that provides contents, to the question about the user's taste. The client (12) generates, in response to the PDI-Q received from the server (11), a user-side PDI-BA expressed by use of a bitmap index and representing a user's answer to the question, and matches the user-side PDI-BA with the provider-side PDI-BA received from the server (11), thereby determining an acquisition of contents delivered from the server (11). The present invention can be applied to a broadcasting system that broadcasts digital television programs.

The present invention can be applied to a broadcasting system that broadcasts digital television programs. Provided is a marine denitration system capable of stably supplying electric energy required when ammonia is generated as a reducing agent for denitration. A marine denitration system (1) provided with an ammonia generator (2) which comprises a hydrogen production unit (81) that produces hydrogen from water and a nitrogen production unit (83) that produces nitrogen from air and generates ammonia from the hydrogen manufactured by the hydrogen production unit (81) and the nitrogen produced by the nitrogen production unit (83), and an SCR catalyst unit (4) which is provided in a second exhaust pipe (L2) serving as an exhaust gas passage of a diesel engine (3) for marine propulsion and, together with the ammonia generated by the ammonia generator (2), denitrates exhaust gas, the marine denitration system being provided with a hybrid exhaust turbosupercharger (5) and a storage battery (67), wherein power generation outputs from the hybrid exhaust turbosupercharger (5) and the storage battery are supplied to the ammonia generator (2).
