A reception unit receives data whose bit rate varies. A signal processing section 118 converts the data received by the reception unit into data of a data format to be transmitted to a client apparatus and stores the data obtained by the conversion into a buffer 120. When data is stored by a given amount into the buffer 120, a transmission section streaming-distributes the data to the client apparatus. A control section 126 additionally stores, when data is not stored by the given amount into the buffer 120 in a given transmission period, dummy data into the buffer 120 until the given amount is reached, and controls the transmission section to transmit the resulting data.

A system ensures reception in low reception or no reception areas and adds regionalized experiences in digital broadcasting. The system includes main transmitter stations and many local or regional transceiver stations. Feedback exists between the local and main transmitter stations to fine tune the transmitted signals based on reception quality, location and the like. The addition of localized or regional content is based on parameters such as user preferences and local data. The regionalized content may vary from local news, local advertisements, customized advertisements, advertisement placement based on social media services data, local emergency warnings, and other parameters. The system addresses both reception issues as well as content regionalization blended with original channel information that are of interest to users of a specific region.
