AUDIO ENHANCED ELECTRONIC INSERTION OF INDICIA INTO VIDEO |
摘要 |
A system and method (40) of altering the audio portion of a live television broadcast signal substantially in real time. The system is used to enhance the effects of live video insertion systems. The broadcast signal is received and separated into a pattern recognition unit (72) in order to recognize predetermined events. The broadcast audio is then altered based on the occurrence of said events. Alterations (68, 70) include modifications to attributes such as volume, tone, pitch, synchronization, echo, reverberation, and frequency profile. Once altered, the audio is re-synchronized (80) with the video channel which has undergone its own modification.
