- the present invention relates to a zapping advertisement system using multiplexing characteristics. Specifically, a zapping advertisement using multiplexing characteristics for efficiently providing a zapping advertisement during a zapping time in various environments while being configured to be interoperable with various environments of a digital receiver. It's about the system.
- digital broadcasting is performed by a communication network, a broadcasting center server that transmits digital broadcasting in response to a request from the outside after producing digital broadcasting, a display device displaying digital broadcasting, and a channel change request from the display apparatus.
- a digital receiving device converts video and audio signals so that the digital broadcasting received from the broadcasting center server can be reproduced on the display device while being transmitted to the center server.
- the video and audio information of the digital broadcasting transmitted from the broadcasting center server are compressed and transmitted in different formats and frequencies, and accordingly, the digital receiving apparatus decodes the received video and audio information of the digital broadcasting in different ways. And a multiplexing process of synchronizing and combining them according to a timeline.
- Such multiplexing can generate a continuous frame by compensating for motion based on a key frame due to the characteristics of compression when reconstructing a stream of a video, but randomly receives or accesses a stream.
- buffering frequently occurs, which requires waiting for the presence of a key frame, and this buffering is used when the digital receiver multiplexes the video and audio according to a time stamp. This will cause a time delay.
- a display device such as a TV does not display any content on a screen for a predetermined time.
- a predetermined time during which no content is displayed on the TV screen when changing a channel will be referred to as a zapping time.
- Korean Patent No. 10-1273891 Invention: Zapping data providing system, providing method and recording medium for the method
- Korean Registered Patent No. 10-1412198 Invention: Zapping advertisement service
- domestic registered patent No. 10-1468662 name of the invention: advertisement providing system according to the ranking
