摘要:
Video quality is improved by encoding video frames based on visual quality feedback received from recipients about decoded video. A video frame is encoded based on whether a previous decoded video frame comprises a severe degradation.

Data transmission over a wireless connection is improved by determining whether packets include a packet containing an end of a data frame, and if the packets are determined to include such a packet, transmitting the packets together over the wireless connection.

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.

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).

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.

One embodiment of the invention includes a method for managing a streaming media service. The method includes receiving a request for a streaming media service from a client. It is noted that the streaming media service includes a media service component. Additionally, the method includes selecting a service manager from a plurality of service managers to provide the request to. Furthermore, the method includes selecting a provider from a plurality of providers of a network to assign the media service component. Moreover, the method includes informing said provider assigned to perform the media service component, enabling the streaming media service to be performed on a streaming media.
摘要:
A method and system for streaming media data to a fixed client and/or a mobile client. In one method embodiment, the present invention recites encoding media data to be streamed to a client into a first multiple description bitstream and into a second multiple description bitstream. The present method then determines the appropriate plurality of servers from a network of servers onto which the first and second multiple description bitstreams should be distributed. The present embodiment then recites distributing the first and second multiple description bitstreams to the appropriate plurality of servers positioned at intermediate nodes throughout a network such that a client is provided with access to the media data via a plurality of transmission paths. The present method is also well suited to redistribution of multiple description bitstreams to servers based upon time-varying demand, client movement, and the like.
