  • Patent number: 7684495
    Abstract: A scalable layered video coding scheme that encodes video data frames into multiple layers, including a base layer of comparatively low quality video and multiple enhancement layers of increasingly higher quality video, adds error resilience to the enhancement layer. Unique resynchronization marks are inserted into the enhancement layer bitstream in headers associated with each video packet, headers associated with each bit plane, and headers associated with each video-of-plane (VOP) segment. Following transmission of the enhancement layer bitstream, the decoder tries to detect errors in the packets. Upon detection, the decoder seeks forward in the bitstream for the next known resynchronization mark. Once this mark is found, the decoder is able to begin decoding the next video packet. With the addition of many resynchronization marks within each frame, the decoder can recover very quickly and with minimal data loss in the event of a packet loss or channel error in the received enhancement layer bitstream.

  • Patent number: 7680190
    Abstract: A video encoding system and method utilizes a three-dimensional (3-D) wavelet transform and entropy coding that utilize motion information in a way to reduce the sensitivity to motion. In one implementation, the coding process initially estimates motion trajectories of pixels in a video object from frame to frame in a video sequence to account for motion of the video object throughout the frames. After motion estimation, a 3-D wavelet transform is applied in two parts. First, a temporal 1-D wavelet transform is applied to the corresponding pixels along the motion trajectories in a time direction. The temporal wavelet transform produces decomposed frames of temporal wavelet transforms, where the spatial correlation within each frame is well preserved. Second, a spatial 2-D wavelet transform is applied to all frames containing the temporal wavelet coefficients. The wavelet transforms produce coefficients within different sub-bands. The process then codes wavelet coefficients.

In one implementation, the coding process initially estimates motion trajectories of pixels in a video object from frame to frame in a video sequence to account for motion of the video object throughout the frames. After motion estimation, a wavelet transform is applied to produce coefficients within different sub-bands. The wavelet coefficients are coded independently for each sub-band to permit easy separation at a decoder, making resolution scalability and temporal scalability natural and easy. In particular, the coefficients are assigned various contexts based on the significance of neighboring samples in previous, current, and next frame, thereby taking advantage of any motion information between frames.

  • Patent number: 7587081
    Abstract: An image collection system collects stereo image data comprising left image data and right image data of a particular scene. An estimator estimates a reference three dimensional image density rating for corresponding reference volumetric cell within the particular scene at a reference range from an imaging unit. An image density compensator compensates for the change in image density rating between the reference volumetric cell and an evaluated volumetric cell by using a compensated three dimensional image density rating based on a range or relative displacement between the reference volumetric cell and the evaluated volumetric cell.

  • Patent number: 7583730
    Abstract: A motion-compensated video encoding scheme employs progressive fine-granularity layered coding to encode macroblocks of video data into frames having multiple layers, including a base layer of comparatively low quality video and multiple enhancement layers of increasingly higher quality video. Some of the enhancement layers in a current frame are predicted from different quality layers in reference frames. The video encoding scheme estimates drifting errors during the encoding and chooses a coding mode for each macroblock in the enhancement layer to maximize high coding efficiency while minimizing drifting errors.

  • Patent number: 7574726
    Abstract: A resource allocation of multiple compressed AV streams delivered over the Internet is disclosed that achieves end-to-end optimal quality through a multimedia streaming TCP-friendly transport (MSTFP) protocol that adaptively estimates the network bandwidth while smoothing the sending rate. Resources allocated dynamically according to a media encoding distortion and network degradation algorithm. A scheme is also disclosed for dynamically estimating the available network bandwidth for streaming of objects, such as MPEG4 multiple video objects, in conjunction with the MSTFP protocol. The scheme can account for packet-loss rates to minimize end-to-end distortion for media delivery.

  • Patent number: 7558244
    Abstract: An implementation of a technology, described herein, for transmitting compressed network transport-layer-protocol headers in a speedy, efficient, inferentially synchronized, and robust manner. An implementation, described herein, models the transmission of compressed headers to the congestion procedure of the network transport-layer protocol (e.g., TCP's). Doing so, the sender of the compressed headers can infer whether the receiver correctly received them. Unlike the slow direct synchronization employed by conventional schemes, this implementation of the present claimed invention inferentially synchronizes by modeling after the congestion procedure of the network transport-layer protocol. This is inherently faster than direct synchronization. Since the implementation performs well over both noiseless and noisy links, it is particularly suited to use over wireless communications channels. This abstract itself is not intended to limit the scope of this patent.

In one embodiment, a mobile computing device may be arranged to retrieve an IMSI including a Mobile Country Code (MCC) and a Mobile Network Code (MNC) and to derive an initial FQDN from the IMSI using an initial MNC rule. The mobile computing device may transmit an initial domain name system (DNS) request comprising the initial FQDN. The mobile computing device may be arranged to derive an alternate FQDN from the IMSI using an alternate MNC rule and to transmit a subsequent DNS request comprising the alternate FQDN when a DNS error message is received in response to the initial DNS request. Other embodiments are described and claimed.
