Description

TECHNICAL FIELD

The present disclosure relates to a content casting method and an electronic device therefor.

BACKGROUND ART

With the wide spread of electronic devices having an Internet connection function, the Internet-of-things (IoT) is being built. In the Internet-of-things (IoT) environment, electronic devices connected via the Internet may collect, share, and analyze data to provide more intelligent services. For example, using data associated with a user, an electronic device may provide a service that has been provided in the electronic device using another electronic device of the user.

When a TV has an Internet connection, content (e.g., movies, music, and/or multimedia) from a contents provider (CP) may be played on the TV via the Internet. For example, the user of a mobile device may want the content provided from a contents provider to be played on the TV as well as the mobile device. The user may want to watch the content that has been watched by the user on the mobile device using another electronic device (e.g., TV).

When information related to the content, which might be desired to be watched, is stored in the electronic device, the user may want to watch the content at a desired time or a free time.

DISCLOSURE OF THE INVENTION

Technical Problem

When the user wants the content that has been played on a mobile device to be played through a TV, the user may cast contents to the TV. For continuous content playback, the user may make a playback reservation for a plurality of contents on the TV. For example, the user may make a playback reservation by adding the content desired to be played to the queue of the TV.

The user may make the playback reservation for the contents desired to be played in the queue of the TV by transmitting a content list to the TV. The TV may sequentially play the contents of the queue. For example, the user may deliver a content list provided by a contents provider to the TV. In this case, a content list irrelevant to the situation of the user may be delivered to the TV. Therefore, regardless of the situation of the user, the TV may sequentially play the contents according to the received content list.

For example, when the user wants to watch the contents for a specified time, the user may have to directly designate the contents corresponding to the specified time and cast them to the TV, or stop playing the contents before completing the playback.

If the user stores information related to the contents wanted to be watched in an electronic device, the user may select at least some of the contents when the user is able to watch the contents and watch the selected contents.

In various embodiments of the present disclosure, a method for playing contents in consideration of a user state is disclosed.
