    摘要: Decoding video data. Receive a first video stream including a first plurality of frames encoded at a first resolution, a second video stream including a second plurality of frames encoded at a second resolution and a residual bitstream encoded at a third resolution. The second plurality of frames correspond to the first plurality of frames encoded at the first resolution and the first resolution is greater than the second resolution and the third resolution is at least between the first and second resolutions. Side information determined based at least on the first plurality of frames and the second plurality of frames. The video data decoded based at least on one received frame of the first plurality of frames, at least one received frame of the second plurality of frames encoded at the second resolution, the residual bitstream encoded at the third resolution, and the side information.

    摘要: Decoding video data. At least one video stream including a first plurality of frames encoded at a first resolution and a second plurality of frames encoded at a second resolution are received, wherein the second plurality of frames encoded at the second resolution directly correspond to at least a subset of the first plurality of frames encoded at the first resolution, and wherein the first resolution is greater than the second resolution. The video stream is decoded based on at least one received frame of the first plurality of frames encoded at the first resolution and at least one received frame of the second plurality of frames encoded at the second resolution.

    摘要: 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.

    摘要: Streaming is discussed. A method for wireless media streaming comprises receiving media data from a remote media source, transmitting the media data over a wireless connection to an electronic device, receiving data-link information, accessing the data-link information at an application layer, and determining at the application layer whether to change a transmission rate of the media data to the electronic device. The data-link information is received from the electronic device. The determination is based at least in part on the data-link information.

    摘要: 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.

    摘要: 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).
