The present technology relates to an information processing device and an information processing method, in which streaming traffic can be subjected to a load dispersion by using a broadcast network.
An information processing device processes a request of contents, to be transmitted from a plurality of receiving devices, and dynamically switches return through communication and return through broadcast, as a return path of a response with respect to the request, on the basis of first identification information for identifying a broadcast area capable of being received by the receiving device, and second identification information for identifying the contents, the first identification information and the second identification information being included in the request, and thus, streaming traffic can be subjected to a load dispersion. The present technology, for example, can be applied to a dedicated server (a switching server) provided on a server backend side.
