20100118190 | CONVERTING IMAGES TO MOVING PICTURE FORMAT - A method for content delivery includes receiving a request for delivery of a still image to a client terminal. A promotional image is selected to be delivered to the client terminal together with the still image. The still image and the promotional image are processed together so as to create an image sequence containing the still image and the promotional image in a moving picture format. Responsively to the request for delivery of the still image, the image sequence is delivered over a network for display in the moving picture format by the client terminal. | 05-13-2010 |
20110225315 | MULTI-STREAM BIT RATE ADAPTATION - A method for communication includes providing an item of media content for streaming in a plurality of versions having different, respective bit rates. The media content is streamed from a server to a client by transmitting a first version of the item over a network at a first bit rate from the server to the client via a server buffer associated with the server and monitoring a fill level of the server buffer while streaming the media content. The server switches to transmitting a second version of the item at a second bit rate, different from the first bit rate, to the client in response to a change in the fill level of the server buffer. | 09-15-2011 |

20120331228 | DYNAMIC CONTENT CACHING - A system for caching content including a server supplying at least one of static and non-static content elements, content distinguishing functionality operative to categorize elements of the non-static content as being either dynamic content elements or pseudodynamic content elements, and caching functionality operative to cache the pseudodynamic content elements. The static content elements are content elements which are identified by at least one of the server and metadata associated with the content elements as being expected not to change, the non-static content elements are content elements which are not identified by the server and/or by metadata associated with the content elements as being static content elements, the pseudodynamic content elements are non-static content elements which, based on observation, are not expected to change, and the dynamic content elements are non-static content elements which are not pseudodynamic. | 12-27-2012 |
20130346318 | SECURE TRANSACTION SYSTEMS AND METHODOLOGIES - A secure transaction system including a content delivery network defining edge gates for secure communication with entities outside the network, each edge gate including at least one of encryption and decryption functionality, the encryption functionality being operative to encrypt customer payment card information into no payment card zone (NPCZ) capsules and the decryption functionality being operative to decrypt the NPCZ capsules into customer payment card information securely supplied to at least one of a plurality of payment processing entities, the content delivery network defining a NPCZ, and a plurality of seller entities within the NPCZ which conduct transactions with a plurality of customers and with at least one of the payment processing entities, and receive, process and transmit customer payment information using the NPCZ capsules, the plurality of seller entities not having access to unencrypted payment card information and not having the ability to decrypt encrypted payment card information. | 12-26-2013 |

20130139159 | APPARATUS AND METHOD THEREOF FOR EFFICIENT EXECUTION OF A GUEST IN A VIRTUALIZED ENVIRONMENT - A method for efficient execution of a guest in a virtualized computing environment is provided. The method comprises causing an execution of at least one virtual machine on a computing hardware, the virtual machine executes a hypervisor in a first security ring; and causing an execution of a single guest program on one of the at least one virtual machines, the single guest program comprises a kernel being executed in the first security ring and at least one application being executed in a second security ring. | 05-30-2013 |
20130145363 | SYSTEM AND METHOD THEREOF FOR RUNNING AN UNMODIFIED GUEST OPERATING SYSTEM IN A PARA-VIRTUALIZED ENVIRONMENT - An apparatus and method of operation in a para-virtualized environment. The method includes executing a first hypervisor on a hardware platform of a computing device; and executing a second hypervisor over the first hypervisor, the second hypervisor is configured to capture at least a privileged instruction called by an unmodified guest program executed over the second hypervisor and cause the first hypervisor to execute an instruction corresponding to the captured privileged instruction, wherein the unmodified guest program and the second hypervisor operate in a user space protection domain, e.g., Ring | 06-06-2013 |
20130179651 | TECHNIQUES FOR HANDLING MEMORY ACCESSES BY PROCESSOR-INDEPENDENT EXECUTABLE CODE IN A MULTI-PROCESSOR ENVIRONMENT - In a computing system where a plurality of processing units may execute a shared code independently, it is necessary to address data issues related to execution of the shared code and separate data. According to various embodiments disclosed herein, the per-processing unit data can be efficiently addressed in a program counter relative mode where data is accessed using a data offset value for each processing unit when the data blocks are positioned at spaces of a predetermined offset value. Further, the per-processing unit of common code in different virtual addresses is mapped to a common physical address. As a result, while each of the processing units access the exact same instruction code in physical memory it accesses a different area in memory for manipulation of data. | 07-11-2013 |
20140052932 | METHOD FOR REDUCING THE OVERHEAD ASSOCIATED WITH A VIRTUAL MACHINE EXIT WHEN HANDLING INSTRUCTIONS RELATED TO DESCRIPTOR TABLES - A computerized method for efficient handling of a privileged instruction executed by a virtual machine (VM). The method comprises identifying when the privileged instruction causes a VM executed on a computing hardware to perform a VM exit; replacing a first virtual-to-physical address mapping to a second virtual-to-physical address mapping respective of a virtual pointer associated with the privileged instruction; and invalidating at least a cache entry in a cache memory allocated to the VM, thereby causing a new translation for the virtual pointer to the second virtual-to-physical address, wherein the second virtual-to-physical address provides a pointer to a physical address in a physical memory in the computing hardware allocated to the VM. | 02-20-2014 |
