A reception device detects whether or not there has been updating of configuration information including correlation information correlated with audio data provided in a program from reception signals received in a broadcast, selects one of a plurality of audio data in accordance with operating input, and includes a decoding unit that decodes audio data that the selecting unit has selected. When the configuration information is updated, the selecting unit selects, out of correlation information included in the configuration information that has been updated, audio data corresponding to correlation information including a predetermined element that is the same as correlation information corresponding to audio data selected before updating.

The present invention provides a method of transmitting a broadcast signal. The method of transmitting a broadcast signal according to the present invention provides a system capable of supporting future broadcast services in environments supporting next-generation hybrid broadcast using terrestrial broadcast networks and the Internet. In addition, efficient signaling methods capable of covering both terrestrial broadcast networks and the Internet in environments supporting future hybrid broadcast are provided.

A method for upgrading a to-be-upgraded device is disclosed. The method includes receiving upgrade data in a cable digital television signal format which is required for upgrading the to-be-upgraded device at a predetermined frequency point via a cable digital television interface, processing the upgrade data and converting it into a format readable to the to-be-upgraded device, and sending it to the to-be-upgraded device via a short-range wireless network. An apparatus for upgrading a to-be-upgraded device and a computer program product are also disclosed.

The present technology relates to a reception device, a reception method, a transmission device, and a transmission method in which a convergence service of broadcasting and communication can be realized more effectively. A FLUTE processing unit is configured to acquire one or more components constituting a specific service of a plurality of services included in broadcast waves of digital broadcasting using an IP transfer system, in accordance with a first control signal including information indicating types and a transfer system of the one or more components constituting the specific service such that the convergence service of broadcasting and communication can be realized more effectively. The present technology is applicable to, for example, a television receiver.

A method of acquiring and accumulating data from a server via a network is provided. A request is transmitted for a plurality of items of data and includes at least one ingestion marker associated with the data. The at least one ingestion marker represents a last occurrence of when a change was made to the data. Data is received with a transfer protocol in response to the request. The data has at least one associated ingestion marker different than the at least one associated ingestion marker transmitted with the request. The received data and the at least one associated ingestion marker is stored in memory. The request is transmitted and the data is received and stored electronically by an electronic client device communicating with the server over the network. A system of acquiring and accumulating Electronic Program Guide (EPG) data from a web-server over a network is also disclosed.
