20080199151 | SYSTEM AND METHOD OF AVOIDING CONNECTION CHANGE WHILE RECORDING - A personal video recorder (PVR) may be designed to capture a recording source which matches the view source displayed on a television, thereby allowing a user to pause and rewind “live TV.” However, during recording, the user may inadvertently change the view source by, for example, accessing an autotune feature within a menu system of the audio/visual system. When this happens, the recording source may be prevented from tracking the view source, thereby allowing the continued recording of the program without loss or interruption while the menu system is active. | 08-21-2008 |
