The present invention relates to a method of synchronizing playback of a digital content between connected devices, the method including: receiving a playback delay time list or a playback sync timestamp from a master device during a playback duty cycle; calculating a playback delay time correction amount by referring to the playback delay time list in order to synchronize playback between a plurality of connected devices including the master device; correcting a playback sync timestamp used in the playback synchronization according to the playback delay time correction amount; and playing a digital content according to the corrected playback sync timestamp, and the slave device applies a different playback delay time in consideration of the slave device's own state, so that the playback of the digital content may be synchronized between the devices connected through the network.

Method of synchronizing playback of digital content between plurality of connected devices and device using the same

The present disclosure relates to a method of synchronizing playback of video and audio of a digital content. The method includes at least: transmitting, by a plurality of devices connected to a network, a video playback delay time, an audio playback delay time, and position information, to a master device; receiving a video playback delay time list or a video playback sync timestamp during a video playback duty cycle; receiving at least one of a virtual synchronization audio delay distance, audio delay distances of the connected devices, a sweet spot position, an audio playback delay time list, and an audio playback sync timestamp during an audio playback duty cycle; determining a video playback delay time correction amount, and correcting the video playback sync timestamp in consideration of the video playback delay time correction amount; and correcting the audio playback sync timestamp with the audio playback delay time correction amount.

By way of example, various methods for reproducing advertisements using a plurality of advertisement vehicles as well as controlling the plurality of advertisement vehicles are provided. In one example, a method for controlling a plurality of advertisement vehicles is provided as follows. Initially, information on the plurality of advertisement vehicles that are going to carry out a specific event is verified. Information on the specific event is sent to the plurality of advertisement vehicles and real-time traffic and/or people density information in an area in which the specific event is to be carried out is collected. A starting location of the specific event may also be determined based on at least one of: the real-time traffic density information or real-time location information of the plurality of advertisement vehicles. Then, driving route guidance with an initial destination set to the starting location of the specific event is sent to the plurality of advertisement vehicles such that the plurality of advertisement vehicles convenes at the starting location of the specific event.

Apparatus and method for using connected vehicles as an advertisement platform

By way of example, novel systems and methods for reproducing advertisements on connected vehicles are disclosed. In one example embodiment, a system for delivering advertisements include a plurality of connected vehicles participating in an advertisement event, and the plurality of connected vehicles is each configured to receive an instruction from one of the connected vehicles or a server over a network to cluster near or at a target area for reproducing an advertisement in a coordinated manner as a group of the connected vehicles.

Provided are a nano bubble generator for irrigating a root canal of a tooth and a dental device including the nano bubble generator. The nano bubble generator may include a generator configured to generate nano-scale bubbles within a fluid, a nozzle connected to the generator and configured to move the fluid containing bubbles that flows in from the generator and to apply the fluid at the end of the nozzle, and an ultrasonic portion disposed in the nozzle and configured to apply ultrasonic waves to the fluid containing the bubbles so that the bubbles are maintained in a distributed form.

Disclosed are a method of generating a watermark, a method of generating a broadcast content including the same, and a watermarking system. The method of generating a watermark according to an exemplary embodiment of the present disclosure includes: determining a size of a target image to which a broadcast content is provided; determining the number of watermarks to be inserted into one frame of the target image; generating a watermark insert pattern by using the size of the target image and the number of watermarks; and scaling up the watermark insert pattern to a predetermined pattern for inserting the watermark insert pattern into an original image of the broadcast content.
