Abstract: This disclosure describes, in part, techniques for adapting bandwidth estimation algorithms to account for local network stalls (e.g., Wi-Fi stalls). For instance, an electronic device may use a pacer component and/or a network socket buffer to detect Wi-Fi stalls. The pacer component and/or the network socket buffer may both be configured to store packets. The pacer component may determine a number of bytes to send to the network socket buffer based on a current bandwidth (or bitrate) estimation value and may move packets from the pacer component to the network socket buffer. If the second queue reaches capacity at a first time and is no longer at capacity at a second subsequent time, a Wi-Fi stall may be detected, and the electronic device may transition from a first state to a second state causing the electronic device to determine whether to update a current bandwidth estimation value.

Abstract: A method and system for indicating the camera position, direction, and field of view in a map or panoramic image comprises a map image window which displays a map or panoramic image of the site to be studied (house, apartment, city, etc.). A detailed view window displays a portion of the map image, taken from a point in the site. A highlighted sector in the map image represents the viewing position, direction, and field of view that the detailed view window displays. When the user changes the field of view in the detailed view window, the highlighted sector in the map image changes in synchronism. The resulting interactive windows allow a person to easily and quickly view and understand the field of view, position, and direction of the image being displayed in the detail view window.
