Live-chase video-description buffer display

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.

What is claimed is: 
     
         1 . 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.   
     
     
         2 . The method of  claim 1 , wherein the live video broadcast relates to a public emergency situation. 
     
     
         3 . The method of  claim 1 , wherein the pre-set maximum buffer size is set to 60 seconds. 
     
     
         4 . The method of  claim 1 , wherein the current buffer size is visually displayed through a numeric display. 
     
     
         5 . The method of  claim 1 , wherein the current buffer size is visually displayed through an indicator on at least a circular, horizontal, and vertical graph. 
     
     
         6 . The method of  claim 1 , wherein a warning is displayed when the current buffer size is greater that the pre-set maximum buffer size. 
     
     
         7 . The method of  claim 1 , wherein the live audio is further compressed in time when the current buffer size if greater than the pre-set maximum buffer size. 
     
     
         8 . The method of  claim 1 , further comprising:
 (f) transmitting the enhanced audio stream to a radio receiver, wherein the transmission is synchronized with the live video broadcast.   
     
     
         9 . The method of  claim 1 , further comprising providing the enhanced audio stream along with the live video broadcast. 
     
     
         10 . The method of  claim 7 , wherein the radio receiver is a digital radio receiver. 
     
     
         11 . 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.   
     
     
         12 . The system of  claim 11 , wherein the current buffer size is visually displayed through a numeric display. 
     
     
         13 . The system of  claim 11 , wherein the current buffer size is visually displayed through an indicator on at least on a circular, horizontal, and vertical graph. 
     
     
         14 . The system of  claim 11 , wherein a warning is shown on an output display if the current buffer size is greater that the pre-set maximum buffer size. 
     
     
         15 . The system of  claim 11 , further comprising: an output communication link for transmitting at least a portion of the memory location storing the enhanced audio stream to a radio receiver, wherein the transmission is synchronized with the live video broadcast. 
     
     
         16 . The system of  claim 13 , wherein the radio receiver is a digital radio receiver. 
     
     
         17 . The system of  claim 11 , wherein the live audio is further compressed in time when the current buffer size if greater than the pre-set maximum buffer size. 
     
     
         18 . The system of  claim 11 , further comprising providing the enhanced audio stream along with the live video broadcast.
