A method of determining a group of user devices suitable for contributing user content to an interactive media broadcast may comprise: —transmitting a set of requirements to a first plurality of user devices (13), each user device having a set of capabilities, the set of requirements relating to using at least part of the user content in the interactive media broadcast, —transmitting an invitation to a second plurality of user devices (13), the invitation being configured to cause a user device to produce a conditional response if the set of capabilities of the user device matches the set of requirements, and —identifying a group of user devices from which a conditional response was received. The method may further comprise selecting a group of user devices from the identified user devices. The selected group of user devices may include all identified user devices. The media broadcast may include an interactive television broadcast.

Provided herein are systems and methods that allow for converting or translating Dynamic Adaptive Streaming over HTTP (DASH) to HTTP Live Streaming (HLS) and vice versa.

Tag data is created from in-band data in a media content item by a remote location while the media content item is being broadcasted by a content provider and received by the remote location. The tag data identifies locations in the media content item which enables media devices to accurately jump to particular locations in the media content item based on the tag data.

The present disclosure is intended to enable playback of media data corresponding to a sensibility effect set in advance. A content playback device (91) of the present disclosure includes: a device table production unit (10) holding a device table in which a format of media data that can be played back and a device parameter are determined for each device; a media table production unit (20) configured to acquire metadata including the format and a sensibility effect label of the media data, determine a mapping evaluation scale that is a device parameter corresponding to the sensibility effect label, and produce a media table in which the mapping evaluation scale and the format are determined for each media data; and a mapping determination unit (30) configured to extract, based on the formats, a combination pattern of a device on which media data can be played back and the media data, select, from among extracted combination patterns, a combination pattern for which a relative error between the device parameter and the mapping evaluation scale is minimum, and select a device that is an output destination of the media data.

A display apparatus for and a method of providing to users additional information associated with a broadcasting signal that is being output via the display apparatus are provided. The display apparatus includes a communication unit configured to perform data communication, and a control unit configured to acquire a keyword from content being reproduced by the display apparatus, to acquire user preference information corresponding to a mobile terminal, to acquire a search result corresponding to the acquired keyword, to produce additional information based on the acquired search result and the acquired user preference information, and to provide the additional information to the mobile terminal via the communication unit.

In some embodiments, an electronic device facilitates selection of a format for the playback of content. In some embodiments, while displaying, via a display generation component, a content playback user interface for a first content item that is playing at the electronic device, wherein the electronic device is playing the first content item in a first format, in accordance with a determination that the first content item is available in a second format, different from the first format, and that a currently-active output device for playing the first content item is compatible with the second format, the electronic device displays, in the content playback user interface, a selectable option that is selectable to initiate a process to switch from playing the first content item in the first format to playing the first content item in the second format.
