20140189816 | EXTENDING SERVER-BASED DESKTOP VIRTUAL MACHINE ARCHITECTURE TO CLIENT MACHINES - A server-based desktop-virtual machines architecture may be extended to a client machine. In one embodiment, a user desktop is remotely accessed from a client system. The remote desktop is generated by a first virtual machine running on a server system, which may comprise one or more server computers. During execution of the first virtual machine, writes to a corresponding virtual disk are directed to a delta disk file or redo log. A copy of the virtual disk is created on the client system. When a user decides to “check out” his or her desktop, the first virtual machine is terminated (if it is running) and a copy of the delta disk is created on the client system. Once the delta disk is present on the client system, a second virtual machine can be started on the client system using the virtual disk and delta disk to provide local access to the user's desktop at the client system. This allows the user to then access his or her desktop without being connected to a network. | 07-03-2014 |

20150201220 | CONDITIONAL GOLOMB BASED ADAPTIVE ENTROPY CODING - An apparatus and method for performing variable length coding (VLC) within an adaptive entropy image coding process are presented. VLC is performed using a progressive coding technique, such as progressive Golomb coding (PGC) whose operation is based on a set of parameters. Grouping is performed within image distribution contexts, such as number of quantized bit planes (qn), previous residual, predictor type, and color, so that each group having similar contexts is associated with a set of progressive coding parameters. The grouping can be performed on-line or off-line. In operation, the progressive coding parameters then change in response to changing image distribution contexts toward optimizing image coding, such as increasing peak signal-to-noise ratio (PSNR). | 07-16-2015 |
