Abstract
An apparatus and a method are proposed which enable an improved control processing for live streaming distribution of tuner received content from a server to a client. By setting a URL to a channel list as a set of channels, and transmitting a content acquisition request from the client to the server, wherein the channel list URL is designated, to a server, the client can collectively obtain rights to control all content on the channels listed in the channel list. By continuously using an HTTP connection set on the basis of a channel list, the client can switch channels.
