Abstract: Determining a location. An initial image is captured at an image capturing device. The initial image is compared with images in a database of images which have associated locations to determine the location of the image capturing device. A user receives a notification if a location cannot be determined.

Abstract: Methods and systems thereof for streaming media data are described. Media data comprising a plurality of data packets is accessed. Information that quantifies a characteristic of each data packet in the plurality of data packets is also accessed. That information is used to determine an order for sending the data packets over a network.

Abstract: According to one embodiment, video data from a video transmitter (110) is received (420) at a network buffer (130). Information that pertains to a network buffer drain rate (14) of the network buffer (1q3) is monitored (430). The network buffer drain rate (140) is a rate that the video data is removed from the network buffer (130). The network buffer drain rate (140) is estimated (440) based on the monitored information. A transmission rate (120) that the video transmitter (110) transmits future video data is adjusted (450) to not exceed an allowed transmission rate (ATR) that is calculated based on the estimation of the network buffer drain rate (140).

Abstract: A computer-implemented method for managing upstream bandwidth of a network including changing QoS settings, by a router, of a video device of a plurality of video devices in the network to a higher priority than other of the plurality of video devices. The plurality of video devices concurrently transmit video data. The computer-implemented method further includes estimating an overall upstream bandwidth by the higher priority video device and determining operating rates, by the router, for the plurality of video devices, such that said modem buffer is not backlogged.

Abstract: A computer-implemented method for encoding using feedback. A base layer of a current frame is encoded. The residue of the current frame is generated. The residue of the current frame is encoded. Also, in response to feedback from a receiver, a coding strategy for each block of the current frame is determined and coding is performed according to one or more of source coding and Wyner-Ziv coding. The feedback is based on the base layer of the current frame and previous correctly received enhancement frames.

Abstract: Methods for adapting the sliding window of sliding window-based error correcting codes based on the coding structure of a compressed media stream are disclosed. In one aspect, a sender packetizes each frame of a media stream to be sent to a receiver into a set of frame packets. The sender also determines compression dependence of each frame and adapts a sliding window of a sliding window-based error correcting code based on the compression dependence of the frame. The sender encodes the frame packets into at least one associated parity packet according to the error correcting code with the adapted sliding window, and sends the frame packets and the at least one associated parity packet to the receiver.

Abstract: Adapting characteristics of a video stream. A video stream is received, at a video adaptation device, which employs a first reference frame. A determination is made, at a video adaptation device, to splice the video stream to employ a second reference frame in place of the first reference frame.
