Abstract: A method to display a representation of multimedia content that includes a progress bar. The method includes shortening a portion of the multimedia content having a start time and an end time from an original length to a shortened length based on a received indication and modifying the progress bar to represent the shortened portion of the multimedia content. The original length of the portion is represented by a curve adjacent to the progress bar, where a first end of the curve is adjacent to the progress bar at a location indicating the start time, and where a second end of the curve is adjacent to the progress bar at a location indicating the end time, and the shortened length of the portion is represented by a distance on the progress bar between the location indicating the start time and the location indicating the end time.

Abstract: A mechanism is provided for controlling the internal air-quality of a vehicle. Responsive to determining that a speed of a vehicle fails to be above the predetermined low-speed threshold, a determination is made as to whether an internal air-quality from an internal air-quality sensor is better than the external air-quality from an external air-quality sensor. Responsive to the internal air-quality being better than the external air-quality, a ventilation control mechanism is signaled to utilize a recirculating-air mode, wherein the ventilation control mechanism either stays in an already initiated recirculation-air mode or switches to the recirculating-air mode. Responsive to the internal air-quality being worse than the external air-quality, the ventilation control mechanism is signaled to utilize a fresh-air mode, wherein the ventilation control mechanism either stays in an already initiated fresh-air mode or switches to the fresh-air mode.
