Abstract
Embodiments of the invention describe a method of generating an enhanced audio stream. The enhanced audio stream is generated from live audio received and accompanies a live video broadcast. This live audio is buffered and combined with a visual description of the live video broadcast. Together these form an enhanced audio stream. The visual description is entered by a visual describer while they are viewing a an instantaneously updated visual buffer size display. The visual buffer size display is calibrated to a pre-set maximum buffer size, and shows the pre-set maximum buffer size and the current buffer size in a visual manner. Further, live audio from the buffer that is inserted into the enhanced audio stream is compressed in time.
Claims18
A method of generating an enhanced audio stream comprising:
- (a) receiving live audio accompanying a live video broadcast;
- (b) buffering the live audio in a buffer;
- (c) inserting into the enhanced audio stream at least a portion of the live audio;
- (d) inserting into the enhanced audio stream at least one visual description of the video broadcast while simultaneously displaying an instantaneously updated visual buffer size display, wherein the visual buffer size display is calibrated to a pre-set maximum buffer size, and wherein the visual buffer size display shows the pre-set maximum buffer size and the current buffer size in a visual manner;
- and
- (e) inserting into the enhanced audio stream, live audio from the buffer, wherein the live audio is compressed in time.
A system for generating an enhanced audio stream comprising:
- an audio input for receiving live audio accompanying a live video broadcast;
- a memory buffer for storing the live audio;
- a microprocessor executing instructions for inserting into a memory location storing an enhanced audio stream, at least a portion of the live audio, and instructions for inserting into the memory location storing an enhanced audio stream at least one visual description of the video broadcast;
- an output display showing an instantaneously updated visual buffer size display, wherein the visual buffer size display is calibrated to a pre-set maximum buffer size, and wherein the visual buffer display shows the pre-set maximum buffer size and the current buffer size in a visual manner;
- and
- the microprocessor executing instructions for storing at the memory location of the enhanced audio stream, live audio from the buffer, wherein the live audio is compressed in time.
