| 20090021639 | Audio and Video Communication - In order to correct the skew experienced by the end user, a ‘reverse skew’ is applied by a video IVR, resulting in synchronized data at the edge. This is achieved by ‘sliding’ the time-bases of audio relative to video prior to delivery. Therefore, the data as received by the end user is synchronized. Media interfaces towards the video IVR are full duplex; the server corrects the skew in the respective halves of the duplex, particularly dependent on the type of service being deployed on the video IVR. For messaging applications, correcting the skew of the received data is important prior to the actual storage of the data. By applying the same technique as used for play-out, the skew can be corrected. The video IVR slides the time-base of audio relative to video before saving the multimedia data to the storage device. As a result, data saved is synchronized. | 01-22-2009 |
