Abstract: According to one embodiment, a video distribution server includes an SSD, a counter, a determination unit, an output unit, and a first and second distribution controller. The first distribution controller, when target content data of a request belongs to a preferential data, reads the target content data from the SSD. The first distribution controller buffers the read target content data in a first storage area included in the output unit, and distributes the buffered target content data to a request source. The first distribution controller caches the read target content data in a second storage area included in the output unit. When the first distribution controller receives a request for the target content data after the caching of the target content data, the first distribution controller distributes the cached target content data to a request source.
