Systems, methods, and computer program products are provided for connecting users and speakers via audio conversations on a mobile application. For example, a method comprises: providing speaker information associated with a speaker, wherein the speaker accesses a mobile application on a first mobile device of the speaker; determining a user accesses a mobile application on a second mobile device of the user; initiating an audio conversation between the speaker and the user; broadcasting, using the one or more computing device processors, on the mobile application, to a listener, a first audio conversation involving the speaker and the user, wherein the listener accesses the mobile application on a third mobile device of the listener.

Provided are a device and a method which are capable of performing selection acquisition and utilization processes for a service worker (SW) that performs data management optimized for each reception device. It is possible to selectively acquire a service worker (SW) of a specific class from service workers (SWs) corresponding to a plurality of classes which are data management programs used in a reception device and have different data management types. For example, use of a service worker (SW) corresponding to a class selected according to an application use state in a reception device is implemented. A reception device acquires access information of a service worker (SW) of a specific class using signaling data in which a token used for efficiently searching for the access information of the service worker (SW) of the specific class is recorded, and acquires the service worker (SW).

Provided are a device and a method which are capable of realizing an efficient search of metadata such as access information corresponding to acquisition-scheduled data in a reception device. A reception device receives a token which is auxiliary search information for efficiently searching for metadata such as access information related to acquisition-scheduled data of the reception device and performs a search process using the token. The token includes a service worker (SW) search scope token capable of limiting a search scope of access information corresponding to data serving as a management target of a specific service worker (SW) which is a data management program and a service worker (SW) cache scope token indicating that access information corresponding to data serving as a management target of a service worker (SW) is collectively recorded.

A vehicle messaging method (600) and system (100) can include any number of data sources (101-103), an interface (104) that formats messages and addresses from the data sources, and a corresponding number of messaging servers (111-113) that receive targeted messages intended for a predetermined subset of subscribers associated with a vehicle identification number (VIN). Each messaging server can include a corresponding controller (121-123) programmed to assign (604) targeted messages to a predetermined channel and encode (606) the addresses of the targeted messages to the predetermined subset of subscribers using a VIN or portion thereof. The controller can be further programmed to transfer (608) the targeted messages and addresses to a satellite uplink (107) and satellite (110) via a messaging uplink interface (106) for retransmission and reception by a plurality of selective call receivers 109 addressable individually using a predetermined VIN or portion thereof.

A server may receive a software update file image and determine that the software update is applicable to a predefined plurality of vehicles within an ATSC broadcast range, based characteristic of those vehicles compared to applicability requirements associated with the software update. Further, the server may instruct an ATSC transmitter to broadcast a file image of the software update, the broadcast including at least one parameter defining the characteristics of vehicles. The processor is also configured to receive feedback from one or more of the plurality of vehicles receiving the file image and responsive to the feedback, instruct adjustment of a broadcast characteristic to increase receipt of the broadcast file image among the plurality of vehicles.
