Abstract
Provided is a system and method of providing a sign language broadcasting service to viewers having hearing impairments, and more particularly, the system and method of providing a sign language broadcasting service that may enable a user to select an option of viewing only a broadcast image, or an option to viewing both the broadcast image and a sign language interpreting image, by transmitting the broadcast image and the sign language interpreting image using different transport streams.
Claims10
A method of providing a sign language broadcasting service, the method comprising:
- encoding a broadcast image of a broadcast program in a form of a transport stream;
- encoding a sign language interpreting image in a form of a transport stream;
- multiplexing the encoded broadcast image and the encoded sign language interpreting image into a single program transport stream;
- and
- transmitting image data resulting from the multiplexing to a broadcast receiver.
A method of receiving a sign language broadcasting service, the method comprising:
- receiving streaming data from a digital broadcast headend system;
- verifying program designation information from the received streaming data;
- determining whether a sign language interpreting image is present in the streaming data, based on the verified program designation information;
- filtering a main broadcast image and a sign language interpreting image from the streaming data, respectively, when the sign language interpreting image is present as a result of the determining;
- and
- composing the filtered main broadcast image and the filtered sign language interpreting image into a single image, and displaying the single image.
A sign language broadcast service system, comprising:
- a digital broadcast headend system to encode each of a broadcast image of a broadcast program and a sign language interpreting image in a form of a transport stream, to multiplex the encoded broadcast image and the encoded sign language interpreting image into a single program transport stream, and to transmit image data resulting from the multiplexing to a broadcast receiver;
- and
- a broadcast receiver to receive streaming data from the digital broadcast headend system, to determine whether a sign language interpreting image is present in the streaming data, based on program designation information verified from the received streaming data, to filter a main broadcast image and the sign language interpreting image from the streaming data, respectively, when the sign language interpreting image is present as a result of the determining, and to compose the filtered main broadcast image and the filtered sign language interpreting image into a single image, and display the single image.
