Abstract: Media content can be synchronized across multiple participant devices. A set of participant devices may request access to stream media content from a content delivery network. Each participant device can send information relating to the playback of the media content to a coordination server. The coordination server can determine a synchronized time for playback of the media content such that all participant devices playback the media content simultaneously. The coordination server can instruct each participant device to playback the media content according to the synchronized time.

Abstract: Described are techniques used for automatic detection of malicious code by verifying that an application executes in accordance with a model defined using calls to a predetermined set of targets, such as external routines. A model is constructed using a static analysis of a binary form of the application, and is comprised of a list of calls to targets, their invocation and target locations, and possibly other call-related information. When the application is executed, dynamic analysis is used to intercept calls to targets and verify them against the model. The verification may involve comparing the invocation and target location, as well as other call-related information, available at the time of call interception to the corresponding information identified by static analysis. A failed verification determines that the application includes malicious code. As an option, once detected, the malicious code may be allowed to execute to gather information about its behavior.
