Method and system for supporting call origination before session establishment
An access terminal establishes a session with a first radio access network (RAN). As a result, the access terminal receives a Unicast Access Terminal Identifier (UATI) assigned by the first RAN and establishes configuration settings for radio communications between the access terminal and the first RAN. The access terminal moves from the first RAN to a second RAN. Before the access terminal has a session established with the second RAN, the access terminal receives a request from a user to originate a call. In response, the access terminal sends the second RAN a connection request that includes the UATI assigned by the first RAN. The second RAN evaluates the UATI included in the connection request and determines that it was previously assigned to the access terminal by another RAN. Based on this determination, the second RAN grants the connection request by assigning a traffic channel to the access terminal. |

Enhanced image capture
Disclosed are techniques that provide a “best” picture taken within a few seconds of the moment when a capture command is received (e.g., when the “shutter” button is pressed). In some situations, several still images are automatically (that is, without the user's input) captured. These images are compared to find a “best” image that is presented to the photographer for consideration. Video is also captured automatically and analyzed to see if there is an action scene or other motion content around the time of the capture command. If the analysis reveals anything interesting, then the video clip is presented to the photographer. The video clip may be cropped to match the still-capture scene and to remove transitory parts. Higher-precision horizon detection may be provided based on motion analysis and on pixel-data analysis. |

Near-lossless video summarization
Described is perceptually near-lossless video summarization for use in maintaining video summaries, which operates to substantially reconstruct an original video in a generally perceptually near-lossless manner.

In one implementation, the metadata is computed and maintained (e.g., as a file) to summarize a relatively large video sequence, by segmenting a video shot into subshots, and selecting keyframes and mosaics based upon motion data corresponding to those subshots. The motion data is maintained as a semantic description associated with the image set. To reconstruct the video, the metadata is processed, including simulating motion using the image set and the semantic description, which recovers the audiovisual content without any significant information loss. |

Hybrid HTTP and UDP content delivery
A hybrid HTTP/UDP delivery protocol provides significant improvements for delivery of video and other content over a network, such as an overlay. The approach is especially useful to address problems (e.g., slow startup times, rebuffering, and low bitrates) for HTTP-based streaming. In general, the protocol has two phases: an HTTP phase, and a UDP phase. In the HTTP phase, the client sends an HTTP GET request to a server. The GET request contains a transport header informing the server that the client would like to use UDP-based transfer over the protocol. The server may refuse this mode and continue in ordinary HTTP mode, or the server may respond by sending an empty response with header information informing the client how to make the connection to enter the UDP phase. In the UDP phase, the client initiates a connection and receives the originally-requested content over UDP. |

Universal asymmetry correction for packet timing protocols
The notion of a “PTP aware” path is one current proposed approach to reduce asymmetry effects. In a fully PTP aware path there is the notion of on-path support mechanisms such as boundary clocks and transparent clocks at every switching or routing node. However, on-path support methods only address time-transfer errors introduced inside network elements and any asymmetry in the transmission medium, such as, for example, the fiber strands for the two directions of transmission, cannot be compensated for by on-path support mechanisms. Furthermore, in a real operational network, which may traverse different operational domains administered by different entities, full on-path support is a difficult challenge. In certain managed network scenarios full on-path support can be contemplated. Nevertheless, the universal asymmetry compensation method described herein mitigates the asymmetry in a network path, without requiring on-path support mechanisms such as transparent clocks and boundary clocks. |
