Abstract
A method for displaying closed-captioning with audio programs. The audio signal data is located and sent to an audio signal processor for conversion into an audio program. The closed-captioning data is located and decoded to produce a textual display synchronized with the audio program. The closed-captioning data is displayed on a remote device, either as part of a consumer electronics system, or as a stand alone network device. The invention also includes one example of an apparatus that receives and decodes the components of a complex audio signal to produce both the audio program and the closed-captioning on the remote device.
Claims9
A method for displaying closed-captioning data for an audio signal on a remote device, comprising the steps of;
- locating and decoding audio signal data;
- locating and decoding closed-captioning data, wherein the closed-captioning data and the audio signal data come from separate sources;
- playing the audio signal data, thereby producing an audio program;
- coordinating timing of the closed-caption data to synchronize the closed-captioning data with the audio program;
- and
- displaying the closed-captioning data on the remote device.
An apparatus for displaying closed-captioning data for an audio signal on a remote device, comprising:
- an audio device operable receive to an audio signal and a closed-captioning component, wherein the closed-captioning component and the audio signal come from separate sources;
- a closed-captioning decoder, operable to convert the closed-captioning component into a textual display;
- an audio signal processor operable to produce an audio program from the audio signal, and to synchronize the closed-captioning component to the audio signal;
- and
- a remote device to display the textual display.
