Abstract: 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.

Abstract: The present disclosure relates to a method of generating a 3D image by recording a digital content. The method includes at least: transmitting, by one or more connected devices, a captured image including the same target object or a point of interest to one device among the plurality of connected devices; receiving camera photographing condition information including at least one of a corrected location of a current device, and a location of the target object, a photographing direction, an image size, and focal length information from one device among the plurality of connected devices; generating a digital content in consideration of the received camera photographing condition information; and transmitting the generated digital content to one device among the plurality of connected devices.

Abstract: By way of example, a method for carrying out an advertisement by a connected vehicle is provide for a specific event. Initially, information on the specific event that is to be carried out by the connected vehicle is received, and in response to receiving the information on the specific event, a request is sent by the connected vehicle to participate in the specific event. Then, driving route guidance to a starting location for the specific event is received and also received is the driving order of a plurality of connected vehicles that are going to participate in a parade proceeding for the specific event.

Abstract: A connected vehicle configured to detect presence of people near the connected vehicle via one or more proximity sensors is disclosed. The connected vehicle may be configured to reproduce one or more audio advertisements via external displays and/or external speakers of the connected vehicle. The one or more advertisements may be reproduced in such a way that the one or more advertisements reproduced may provide the people with an alert message informing them of the presence of the connected vehicle, in place of imaginary engine sounds, for safety of people outside the connected vehicle.

Abstract: 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.

Abstract: By way of example, novel systems and methods for reproducing advertisements on connected vehicles are disclosed. In one example embodiment, a system of connected vehicles parked near in a parking lot and each delivers advertisement and participates in an advertisement event. Each of the connected vehicles is configured to reproduce one or more advertisements when one of the connected vehicles is determined to receive a signal from a remote controller associated with the one of the connected vehicles.

Abstract: 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.

Abstract: By way of example, a connected vehicle in the form of an electric vehicle is disclosed that the electric vehicle includes an advertisement system, which is configured to: detect presence of people near the connected vehicle via one or more proximity sensors; and reproduce, in response to the detection of presence of people, one or more advertisements via external displays and/or external speakers of the connected vehicle. Further, the connected vehicle may include an advertisement identification unit coupled to the advertisement system and configured to recognize and identify one or more visual contents of an advertisement reproduced on an external display of another vehicle or a billboard display nearby.

Abstract: By way of example, a connected vehicle including an in-vehicle audio system and an advertisement system. The in-vehicle audio system is configured to stream music inside the connected vehicle for one or more occupants in the connected vehicle and the advertisement system is coupled to the in-vehicle audio system and is configured to: detect the playing of the music, and reproduce, based on the music played, one or more advertisements for the one or more occupants inside the connected vehicle. Further, the one or more advertisements may be created based on a melody or one or more segments of the music that is played.

Abstract: By way of example, novel systems and methods for delivering advertisement contents to connected vehicles are disclosed. A system for delivering advertisement contents to one or more connected vehicles over a network include a plurality of connected vehicles coupled to a server. The plurality of connected vehicles may be in communications with the server via a first wireless network and may be in communications with each other, and the server may be configured to manage and deliver advertisement contents to the connected vehicles over the network. Each connected vehicle may be configured to output, via an electronic display means and/or an audio means, the advertisement contents, which may be selected based in part on location information of the connected vehicles, local time information, or attributes of people around the connected vehicles. As a result, the effect of delivery of the advertisement contents may be significantly increased by using the connected vehicles.
