The present technology relates to a demodulation device, a processing device, a reception device, and a data processing method for more flexibly coping with change in transmission method. A demodulation device includes a demodulation unit configured to demodulate a first transmission packet obtained from a broadcast signal, and an output unit configured to output a divided packet via a predetermined interface, the divided packet being obtained by dividing the first transmission packet that is a variable-length packet used in a first transmission method into a packet length according to a second transmission packet that is a fixed-length packet used in a second transmission method and arranging the first transmission packet in a payload, and adding a header including information for restoring the first transmission packet to the payload. The present technology can be applied to, for example, a demodulation IC incorporated in a television receiver or a set top box.

The present invention provides a method for transmitting a broadcasting signal. A method for transmitting a broadcasting signal according to the present invention suggests a system capable of supporting a next generation broadcasting service in an environment which supports a next generation hybrid broadcast using a terrestrial broadcast network and an internet network. Furthermore, in an environment which supports a next generation hybrid broadcast, suggested is an efficient signaling scheme which can embrace both a terrestrial broadcast network and an internet network.

The present invention proposes a signalling method which can support effectively next-generation broadcast service in an environment which supports next-generation hybrid broadcast using terrestrial broadcast networks and the Internet. The signalling method comprises a broadcast reception method which can use a mobile reception device or can be used even in an indoor environment. The broadcast reception method may comprise the steps of: receiving a broadcast signal including service; establishing a web socket connection from an application of a companion screen device; generating a notification message for the service; and transferring the notification message to the companion screen device through the web socket connection.

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.

Systems and methods are provided for accessing broadcast media items and segments from non-broadcast sources. In response to detecting that a user has not finished listening to a broadcast segment (e.g., a radio segment), an electronic device can automatically identify and access an alternate, non-broadcast source for the same broadcast segment (e.g., a corresponding podcast episode). Using the electronic device, a user can play back the segment from the non-broadcast source, starting playback at the last position of the broadcast segment when the user stopped listening to the broadcast. In some embodiments, the electronic device can update library counts (e.g., play counts and new/not new tags) based on media items and segments played back as part of a media broadcast.

The present technology relates to an information processing apparatus, information processing method, transmission apparatus, and transmission method, capable of improving the convenience of a voice AI assistance service used in cooperation with content.

The convenience of the voice AI assistance service used in cooperation with the content can be improved by providing an information processing apparatus including a control unit configured to control a timing of a voice response upon using a voice AI assistance service in cooperation with content on the basis of voice response time information indicating time suitable for the voice response to an utterance of a viewer watching the content. The present technology can be applied to a system in cooperation with a voice AI assistance service, for example.

Disclosed is a content-view supporting system to recommend to a user a clear result of searched contents, based on a group of similar users' favorite programs, through a user-basis collaborative filtering process. The system selects similar users whose program view history is similar to that of a recommended user, maps the program view history in a collaborative filtering matrix registers, in the collaborative filtering matrix, a virtual user whose program view history includes a group of hit programs obtained based on a search condition served for realizing a predetermined search topic. The system also counts the numbers of reservations or views achieved by each user according to program content based on the program view history, in the collaborative filtering matrix, which counted numbers are set as matching numbers, and outputs a search result representing a recommendation list of the contents arrayed in the descending order of matching number.

A media device including a broadcast receiver that receives broadcast media from a plurality of broadcast sources where the broadcast receiver is tunable to a first broadcast source. The media device also includes a data store that stores a list of contact identifiers where each contact identifier is associated with a broadcast source. The media device includes a user interface that: i) provides a prompt to a user to enable the user to initiate contact with the first broadcast source, and ii) receives a user indication to initiate contact with the first broadcast source. The media device further includes a transceiver that initiates the contact with the first broadcast source by sending a communications session request via a communications network to the first broadcast source that includes a contact identifier associated with the first broadcast source.
