Description

Smart sign language video disaster service method and device

[0001] The present invention relates to a smart sign language video disaster service method and device.

[0002] Digital broadcasting technology can broadcast not only digital broadcasting content but also various other types of information, and one of the types of information that can be broadcast is disaster broadcasting.

[0003] Digital broadcasting technology can transmit disaster information messages containing disaster information and disaster response guidelines through broadcasting companies' channels in the event of natural disasters such as earthquakes, heavy snow, and heavy rain, or social disasters such as large-scale fires and forest fires.

[0004] ATSC (Advanced Television System Committee) 3.0 is an IP-based transmission method that can provide not only basic TV services but also various additional services such as service guides, HTML (HyperText Markup Language)5 app services, on-demand video, mobile linkage services, and dynamic advertising through a hybrid broadcasting environment that combines broadcasting and telecommunications networks. In particular, ATSC 3.0 can use wake-up functions and location information to deliver disaster alerts to idle receivers in disaster areas.

[0005] Meanwhile, many countries are enacting laws prohibiting discrimination against persons with disabilities and protecting their rights, thereby supporting them to access diverse information through television.

[0006] Sign language broadcasting services, in particular, are broadcasting services that provide sign language interpretation for people with hearing impairments. Along with closed captioning, sign language broadcasting services provide convenience for people with hearing impairments, serving as a crucial means of ensuring equal access to broadcasting services for those without disabilities.

[0007] However, there is a need for disaster warning text messages that require urgent provision to be provided in a customized manner for the hearing impaired, a vulnerable group, despite the fact that there are still many shortcomings.

[0008] The present disclosure provides a method and device for generating a sign language video using text-based disaster information so that a disaster information-sensitive vulnerable class can understand the disaster information well, and transmitting the sign language video to a terminal of a disaster information-sensitive vulnerable class using a broadcasting network and a communication network.

[0009] According to one feature, a method of operating a terminal includes the steps of: receiving a disaster information message from a disaster information broadcasting platform device through a broadcasting network; executing a service app using service information obtained from the disaster information message; receiving URL (Uniform Resource Locator) information of a streaming protocol for receiving a sign language video related to disaster information from the disaster information broadcasting platform device; and connecting to a disaster information media platform device connected to a communication network using the URL information through the executed service app, and receiving and playing the sign language video from the disaster information media platform device.

[0010] The above disaster information message includes an Advanced Emergence Alert Table (AEAT) message and an Application Signaling Table (AST) message, and the executing step may execute the service app using media information obtained from the AEAT message, information for connecting to the disaster information broadcasting platform device obtained from the AST message, and information for executing the app.

[0011] The above URL information can be received by being added to the AEAT message and the AST message.

[0012] The above URL information may include HLS (HTTP Live Streaming) URL information obtained by the disaster information broadcasting platform device from the disaster information media platform device.

[0013] The above-described executing step may include setting up an HLS (HTTP Live Streaming) playback environment in conjunction with the disaster information broadcasting platform device.

[0014] After the above-described playing step, after the above-described playing is finished, a step of receiving a file of the entire sign language video through a broadcasting network from the disaster information broadcasting platform device may be further included.

[0015] According to another feature, the disaster information media platform device includes a disaster information receiving unit that receives disaster information from a disaster announcement platform device, a sign language image generating unit that generates a sign language image using the disaster information, a conversion unit that converts the sign language image into a media format playable on a terminal, a terminal linking unit that streams the converted sign language image to the terminal, and a platform linking unit that transmits URL (Uniform Resource Locator) information capable of receiving streaming of the converted sign language image to the disaster information broadcasting platform device, wherein the URL information is transmitted to the terminal by the disaster information broadcasting platform device and is used by the terminal to receive the converted sign language image.

[0016] The above-mentioned converted sign language image can be transmitted to the terminal through a communication network, and the above-mentioned URL information can be transmitted to the terminal through a broadcasting network.

[0017] The above sign language video generation unit can select a standard text of a disaster type obtained from the received disaster information from among a plurality of standard texts matching each disaster type, and generate the sign language video based on the sign language animation information by configuring sign language animation information using information included in the selected standard text.

[0018] When the streaming transmission of the sign language video ends, the sign language video generation unit generates the entire sign language video as a file in a preset media format, and transmits the generated sign language video file to the disaster information broadcasting platform device, and the sign language video file can be transmitted to the terminal by the disaster information broadcasting platform device.

[0019] According to another feature, the disaster information broadcasting platform device includes a disaster information receiving unit that receives disaster information from a disaster issuance platform device, a broadcasting transmitting unit that transmits a disaster broadcasting message including the disaster information to the terminal, and an app server unit that transmits an app signaling message using the disaster information to the terminal, wherein the disaster broadcasting message and the app signaling message can be used to cause the terminal to connect to the disaster information media platform device and execute a service app for receiving a sign language video related to the disaster information.

[0020] The above disaster broadcast message may be an AEAT (Advanced Emergence Alert Table) message containing media information for executing the service app, and the app signaling message may be an AST (Application Signaling Table) message containing information for connecting to the terminal and information for executing the service app.

[0021] The above broadcast transmission unit may add HLS (HTTP Live Streaming) URL (Uniform Resource Locator) information of the sign language video received from the disaster information media platform device to the disaster broadcast message and transmit the same to the terminal, and the app server unit may add the HLS URL information received from the disaster information media platform device to the app signaling message and transmit the same to the terminal.

[0022] The above app server unit can set an app environment so that a service app running on the terminal can play HLS streaming using the HLS URL information.

[0023] The above disaster information broadcast platform device further includes a sign language video information receiving unit that transmits information received from the disaster information media platform device to the broadcast transmission unit and the app server unit, and receives a media file of a sign language video from the disaster information media platform device and transmits it to the broadcast transmission unit, and the broadcast transmission unit can transmit the media file of the sign language video to the terminal through a broadcast network.

[0024] According to the present disclosure, real-time disaster information occurring in real time can be streamed in the form of sign language video that can be easily understood by hearing-impaired people, thereby helping them to quickly recognize disaster information and take necessary measures.
