Abstract

A system and method (40) for altering the audio portion of a live television broadcast signal substantially in real time. The system is used to improve the effects of live video insertion systems. The transmit signal is received and separated in a pattern recognition unit (72) to recognize predetermined events. The audio of the transmission is then altered based on the occurrence of said events. The alterations (68, 70) include modifications to the attributes such as volume, tone, synchronization, cco, reverberation and frequency profile. Once altered, the audio is resynchronized (80) with the video channel that has undergone its own modification.

ENROLLMENT ELEC OF IMPROVED AUDIO INDEXES IN VIDEO Reference to Related Requests The patent application claims the priority and benefits of the United States Patent Application Provisional number 60 / 016,419 pi on April 29, 1996 entitled "Insertion Eleclindica of Indications of Improved Audio in Video ". ncecedendenles of the invention I. Field of the Invention This invention relates to the improved performance of devices for instructing realistic clues in video sequences, and particularly, to the enhancement by addition of audio effects related to the inserts. 2. Description of the Related Art Electronic devices for inserting electronic images into live video signals, such as those described in U.S. Patent 5,264,933 to Rosser, al., And U.S. Patent No. 5,491, 5 17 of Kieilman, cl al., have been developed and used concially for the purpose of inserting advertisements and signs into video sequences, including live broadcasts of sporting events. In varying degrees of success, these devices incorporate seamlessly and realistically clues into the original video in real time. Realism is maintained even when the original scene quickly approaches or recedes, is taken in panoramic or is altered in another way in size or perspective.

U.S. Patent No. 5,204,933 to R? Sser, cl al., Pi notes having the insertion to the video in response to the sound in the event, i.e., making the video insertion press or change color in response to an increase in the sound of the public. Without it, do not picscnla the possibility invi sa of agi cgai un. what i sound to audio to match a video insert, ie, add a rhythm to the program sound to match the insertion beat, or alter the program's timidity in response to audio or visual cues in the program or in response to some operator command.

Other patents related to video insertion technology, such as U.S. Patent 5,591,517 to Kreitman, al., United States Patent 5,353,392 to Luquet, al., Or Palente in the United States, number 5,488,075 to Uanna. or PCT Requests PCT / US94 / 01679 and PCT / US94 / I 1527 of Shai iy 'l'amir are confined to the portion of the video of a transmission. None of the aforementioned palenls or applications present methods to make an inserted cue seem more realistic by adding audi effects. synchronized.

SUMMARY OF THE INVENTION The invention comprises at the same time a method and apparatus for improving the real-time insertion of video clues by altering the audio portion of a transmission as well as the video portion of the transmission. The invention applies equally well to the real-time insertion of video indicia achieved by means of pattern recognition technology; by means of camera movement sensors coupled to the cameras that record the event, or by means of a combination of pattern recognition and camera in? mmemory sensors.

In the present invention, each photograph or animated video sequence for insertion into live video has an audio sequence. When the still image, animated image sequence or video sequence is inserted, the related sound sequence is also activated. The activation of the sound can be initiated due to the beginning of the insertion; some action in the insertion video portion; Any action on either the video or audi channel? of the tiansmisión; they had some combination of action in the audio and video channel or in the country or Complelamenle, by an operator. In addition to the start, the corrido, the volume, the modulation, termination or any other atrium of the related sound sequence, can be influenced by the image, animation or video inserts, the audio or video channel of the event, some combination of the audio and video channel of the event 5 partially or completely by an operator.

The related audio sequence is stored either digitally in the memory system in the same way that the video sequences are stored or separately in any analog or digital medium. I I) A live video insertion system is improved so that, in addition to the channels for the video and audio insertion of the program, an improved audio processor is added within an audio channel. In a standard live v \ co insertion system the audio channel is just a delay line that pei nóle al Program audio will be delayed during video processing. The enhanced audio interface interacted with the rec? N? Cimienl? of patterns and the tracking of the live video insertion system (LV1S'M). If the audio mix is done digitally, there are also means to convert the audio from analog to digital prog ania and back to analog after making the mix. 0 The enhanced audio processor also includes means for recognition of audio pads to add an audio sequence to the audio of the transmission, or to alter the audio of the transmission in another way. The icc? I-? Eimicnl? of audi pailones? it can be used alone or in conjunction with commands for the recognition of 5 video patterns and the LVIS tracking module. It can also be used in conjunction with operator commands.

Make an insolated clue appear c? M? It is really important that the original video scene is an impoitanle aspect of technology. Audio tracks The appropriate illusions may improve the visual illusion that the clue to inserted video is part of the original scene. The amplification of the audio of the illusion is particularly effective if the inserted cue is an animated sequence and the added audio is programmed to coincide with specific actions of the animation. For example, a video cue? inserted can be programmed to press on and off. To improve this illusion, a sound effect can increase or decrease in volume in synchronization with the insertion of pulsating video. Olios examples include pitch change, reverb, added echo, dialog? spoken or musical jingles of an audio insert that are synchronized with changes in the video? inserted.

The alteration of the sound? of the original program instead of adding an inserl? Audio can also be done separately. For example, public noise can be artificially modulated to coincide with a change in the inserted logo. Consider an animated version of a team mascot. As the artificially inserted team mascot raises and lowers his arms, the volume of the audience would rise or fall in accordance with the illusion that the mascot was actually in the stadium.

Other improvements include the synchronization of an audio addition or the audio of the actual transmission with an audio track. or visual that occurs in the action of the event that is transmitted. In a baseball game, for example, an insemination of an animated pei can react to an audi event. It is the hit of the bat with an appropriate phrase in the character's distinctive voice. Or, the reaction could be synchronized to a visual clue as is the trip of the bale. A combination of visual and audi clues Can you activate partial? completely by an operator and can be synchronized to an evenlo how the start? the end of an entry. Also, if the insei l? In a game of baseball seems to be hit by the ball, a sound? What seems to be coming from the injured insert could be added to the audi? of the program. Using familiar dialogue recognition techniques, the audio track could be a command, a well-known phrase or a team name.

The s? Nid? aggregate can follow the movement of a video insert. For example, the volume related to the insert could increase as the camera zooms in quickly and the insert grows in size. For stereo transmissions, the proportion of the left channels? and right can be altered as the insert takes panning to the side so that the sound seems to follow the insert.

The Search / Tracking / Vei module 42 cs equivalent to the camera parameters extraction module in pending PCT applications PCT / US94 / 01679 and PCT / US94 / 1 1527 from Shai ir and Tamil Id m? dul? Search / Tracking / Verification 42 uses pailon recognition, information from sensors coupled to the camera, a signal from the adjustment signal from a communication switch, or some combination of these sources of information, to determine which camera is watching the scene. The module 42 then calculates the orientation and field of view of the camera by reproducing them as warp parameters m? 20 (Figure 2) that link the view of the current chamber to a view of rcfeiencia. The parameters of utdimbi e 20 are det ivan of the recognition of pailones and are expressed as a transformation related with i especio to a reference view of that camera. However, the paiamelios de ui dubber can be any appropriate mathematical transformation, even more without being modified, move them as is a complete perspective transformation With reference to Figure 2, the urdimbie parameters 20 are used in conjunction with a synthetic reference image 22 in an occlusion processor 44 to generate a key 32 indicating which part of the live video 28 where a logo 26 is going to insert has objects that logo cl 20 should not obscure A major improvement over conventional blue screen occlusion processing technology is that occlusion of the present system can be carried out on textured surfaces. The insert processor 40 (Figui a I) takes the key 32 and a log? 20 and place the 20 denio logo image of the live video 28 so that the logo image 20 looks as if it were part of the original scene.

The image of the l? G? Tip? 20 can it be another video source, even an animated clip from a device? video storage 30. The video storage device? 30 is a digital tape recorder or a digital video disc or other appropriate storage media. The video storage device 36 is controlled by means of information from the Search / Tracking / Verification module 42 or by means of a system operator so that the appropriate animation is chosen and activated at the appropriate time to correspond to c? n the action in the video transmission? Live. For exampleIn a baseball game an animation sequence could be the logo of a paliocinad's becoming a team mascot right after the batter has tried to hit the ball. Different animation sequences could be chosen by an operator depending on whether the hit attempt was successful? ? if the pitching was a slrike or a ball.

In the present invention, a typical live video insemination system (LVIS1M) 40 is modified by the addition of an improved audio preview 00, as schematically shown in Figure I. The improved audio processor 00 is an audio processor that interprets and responds to power of an image recognition and tracking module 42 of the LVISIM 40 system.
