Abstract
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.
Claims26
A method of altering the audio portion of a live television broadcast signal substantially in real time, said method comprising the steps of:
- (a) receiving 18 said live television broadcast signal;
- (b) separating the video and audio portions of said live television broadcast signal into separate channels;
- (c) delaying 28 the video portion of said live television broadcast signal;
- (d) recognizing 72 an event within the audio or video portion of said live television broadcast signal;
- (e) altering 6870 the audio portion of said live television broadcast signal based upon said event;
- (f) re-synchronizing 80 the audio and video portions of said live television broadcast signal;
- and
- (g) outputting 50 the audio altered live television broadcast signal.
A method of altering the audio portion of a live television broadcast signal substantially in real time, said method comprising the steps of:
- (a) receiving 18 said live television broadcast signal;
- (b) converting 74 said live television broadcast signal from the analog domain to the digital domain;
- (c) separating the video and audio portions of said live television broadcast signal into separate channels;
- (d) delaying 28 the video portion of said live television broadcast signal;
- (e) recognizing an event within the audio 72 or video 64 portion of said live television broadcast signal;
- (f) altering 6870 the audio portion of said live television broadcast signal based upon said event;
- (g) re-synchronizing 80 the audio and video portions of said live television broadcast signal;
- (h) re-converting 82 said live television broadcast signal back to the analog domain;
- and
- (i) outputting 50 the audio altered live television broadcast signal.
A method of altering the audio and video portion of a live television broadcast signal substantially in real time, said method comprising the steps of:
- (a) receiving 18 said live television broadcast signal;
- (b) converting 74 said live television broadcast signal from the analog domain to the digital domain;
- (c) separating the video and audio portions of said live television broadcast signal into separate channels;
- (d) delaying 28 the video portion of said live television broadcast signal;
- (e) recognizing at least one event within the audio 72 or video 64 portion of said live television broadcast signal;
- (f) altering 6870 the audio portion of said live television broadcast signal based upon said at least one event;
- (g) altering the video portion of said live television broadcast signal based upon the same or a different one of said at least one event;
- (h) re-synchronizing 80 the audio and video portions of said live television broadcast signal;
- (i) re-converting 82 said live television broadcast signal back to the analog domain;
- and
- (j) outputting 50 the audio altered live television broadcast signal.
A system for altering the audio portion of a live television broadcast signal substantially in real time comprising:
- separation means for separating the audio and video portions of said live television broadcast signal into separate channels which are independently manipulatable;
- audio pattern recognition means 72 for recognizing an event within the audio portion of said live television broadcast signal;
- audio processor means 60 for receiving said audio portion of said live television broadcast signal and altering same based upon said event;
- and,
- re-synchronization means for re-synchronizing the audio and video portions of said live television broadcast signal after said live television broadcast signal audio portion has been altered.
