Description

The present invention relates to a receiver, a presentation method, and a presentation program for presenting broadcast contents.

Conventionally, broadcast content has shifted to digital broadcasting, and high-resolution multi-channel video content has been provided. Further, a method of switching to alternative content has been proposed when such broadcast content cannot be received and presented for some reason.

Patent Document 1 proposes a technique for reproducing unscrambled one-segment broadcasting or series broadcasting as alternative content when descrambled scrambled broadcasting content cannot be performed.
Patent Document 2 proposes a technique for acquiring alternative content from a network when the content has expired when the content is stored and played on a receiver.
According to Patent Document 3, when layer transmission is performed in broadcasting, if the data transmitted by a high layer with weak error tolerance cannot be correctly received, the video and audio are independently more resistant. A technique for switching to a low-level transmission has been proposed.

By the way, a receiver presenting a digital broadcast needs various operations such as establishment of synchronization with a received signal, deinterleaving, and decoding after channel selection. For this reason, the presentation of the video and audio contents did not start immediately after the channel selection, and the higher the quality of the contents, the longer the waiting time until the start of viewing.
Therefore, the viewing behavior that was common in analog broadcasting, called zapping, which changes channels one after another, is virtually non-functional. The lack of zapping makes it difficult to guide viewers who haven't decided what they want to see.

On the other hand, in the so-called OTT (Over-The-Top) service, how quickly playback can be started after the content is selected is an important factor for the user to use the service. The same applies to broadcast content. In an environment where various media including Internet services can be viewed, the length of time required during the transition from the channel selection operation to the presentation of the content is the competition as media. The result was to reduce power.

All of the above-mentioned techniques of Patent Documents 1 to 3 are those after the channel selection operation is in a state where stable reception and presentation can be performed, and do not shorten the required time at the time of transition.

An object of the present invention is to provide a receiver, a presentation method, and a presentation program capable of shortening the waiting time after selection of digital broadcasting.

The receiver according to the present invention is the first presenting unit that receives and presents the broadcast content of the selected channel according to the channel selection operation, and the channel selected according to the channel selection operation. After the second presenting unit that receives and presents the associated alternative content and the second presenting unit start presenting the alternative content, the first presenting unit can present the broadcast content. At that time, a switching control unit for switching from the presentation of the alternative content by the second presentation unit to the presentation of the broadcast content by the first presentation unit is provided.

The second presenting unit may provide a channel selection interface that displays a list of images of the alternative content associated with each of the plurality of channels, and may accept the channel selection operation from the list.

The second presenting unit may display a plurality of linked images of the alternative contents as the channel selection interface, and may display one alternative content according to the channel selection operation.

The second presenting unit may receive the linked image as one content, and may enlarge the linked image to display the one alternative content in response to the channel selection operation.

The alternative content may be transmitted via a communication network.

The presentation method according to the present invention is a method of presenting broadcast content by a receiver, in which alternative content associated with a selected channel is received and presented in response to a channel selection operation, and the channel is selected. After receiving the broadcast content of the channel and starting the presentation of the alternative content, when the presentation of the broadcast content becomes possible, the presentation of the alternative content is switched to the presentation of the broadcast content.

The presentation program according to the present invention is a broadcast content presentation program, in which a receiver receives and presents alternative content associated with a selected channel in response to a channel selection operation, and the channel selection is performed. After receiving the broadcast content of the channel and starting the presentation of the alternative content, when the presentation of the broadcast content becomes possible, the presentation of the alternative content is switched to the presentation of the broadcast content.

According to the present invention, the waiting time after selecting a digital broadcast can be shortened.
