Abstract: A method and system for discovering and testing security assets is provided. Based on source definition data describing sources to monitor on the one or more computer networks, an example system scans the sources to identify security assets. The system analyses the security assets to identify characteristics of the server-based applications. The system stores database records describing the security assets and the identified characteristics. The system queries the database records to select, based at least on the identified characteristics, one or more target assets, from the security assets, on which to conduct one or more security tests. Responsive to selecting the one or more target assets, the system conducts the one or more security tests on the one or more target assets. The system identifies one or more security vulnerabilities at the one or more target assets based on the conducted one or more security tests.

Abstract: Techniques are described for detecting faults in media content based on the behavior of users viewing the media content. Embodiments stream a first instance of media content to one or more users. The behavior of the one or more users is monitored while the users are viewing the streaming first instance of media content. Embodiments then determine whether the first instance of media content is faulty, based on the monitored behavior of the one or more users.

Abstract: Embodiments of the invention generally provide a method, a computing system, and a computer-readable medium configured to respond to requests for payload data and provide unique cache keys for caching the payload data. The computer-implemented method includes accepting a first request for translation that specifies a first path configured to identify first payload data associated with a graph object. The computer-implemented method further includes determining that the graph object includes a first translation node associated with a first portion of the first path. The computer-implemented method also includes obtaining, from the graph object, a second path that is associated with the first translation node. The computer-implemented method further includes replacing the first portion of the first path with the second path to generate a first translated path. The computer-implemented method also includes obtaining, from the graph object, the first payload data, based on the first translated path.

Abstract: Embodiments provide techniques for presenting a user interface. An initial interface containing a first plurality of selectable elements is presented to a user. Embodiments assign the user to a first one of a plurality of preference groups. A plurality of selections made by the user of selectable elements from the plurality of selectable elements are detected. Embodiments then generate a second interface for the user that includes a second plurality of selectable elements, based on the first preference group to which the user is assigned and the selectable elements selected by the user.

Abstract: One embodiment of the present invention sets forth a technique for identifying active streaming connections associated with a particular user account. Each active streaming connection transmits heartbeat packets periodically to a server that tracks the receipt of the heartbeat packets. If, for a particular streaming connection, the server stops receiving heartbeat packets, then the server is able to infer that the streaming connection has been terminated.

Abstract: Techniques are described for determining relationships between user activities and determining search results and content recommendations based on the relationships. A plays-related-to-searches application may determine a relationship score between plays of a media title and searches of a query by determining a distance between a projection of the search onto the space of the users and a projection of plays of the media title onto the space of the users. A plays-after-searches application may determine a score for plays of the streaming media title given the search by multiplying a number of times plays of the media title occur after the query is entered by the number of times any play occurs, and dividing by a product of the number of times plays of the media title occur after any query is entered and the number of times plays of any media title occur after the query is entered.

Abstract: One embodiment of the present invention sets forth a technique for adapting playback bit rate in a content delivery system based on scene complexity of the video content as well as network conditions and other performance factors. A scene complexity map of the video content indicates the complexity levels of different scenes within the video content. Using the scene complexity map, a content player may download scenes of lower scene complexity levels from video streams encoded to lower bit rates to manage the bandwidth consumed to download the video content and allow for the downloading of scenes of higher complexity levels from video streams encoded to higher bit rates.

Abstract translation: 本发明的一个实施例提出了一种基于视频内容的场景复杂度以及网络条件和其他性能因素来适应内容传送系统中的重放比特率的技术。 视频内容的场景复杂度映射表示视频内容中不同场景的复杂度水平。 使用场景复杂度图，内容播放器可以从编码为较低比特率的视频流中下载较低场景复杂度级别的场景，以管理下载视频内容所消耗的带宽，并允许从编码的视频流中下载更高复杂度的场景 到更高的比特率。

Abstract: Techniques are disclosed for improving user experience of multimedia streaming over computer networks. For example, a method for presenting multimedia content may generally include receiving a request to stream a media title. In response to the request, unencrypted content for the media title is streamed to a client. While streaming the unencrypted content, a digital rights management (DRM) license to access encrypted content for the media title is requested. After receiving the DRM license, the client switches from streaming the unencrypted content for the media title to streaming encrypted content for the media title. The switching from streaming the unencrypted content to streaming the encrypted content does not interrupt playback of the media title.

Abstract translation: 公开了用于改善计算机网络上的多媒体流的用户体验的技术。 例如，用于呈现多媒体内容的方法通常可以包括接收流媒体标题的请求。 响应于该请求，媒体标题的未加密的内容被流传输给客户端。 在流式传输未加密内容的同时，请求访问媒体标题的加密内容的数字版权管理（DRM）许可。 在接收到DRM许可之后，客户端将用于媒体标题的未加密内容流传输到用于媒体标题的流加密内容。 将未加密的内容从流式传输到加密内容的切换不会中断媒体标题的回放。

Abstract: One embodiment of the present invention sets forth a technique for testing a client for audio/video/subtitle playback capabilities. A computing device is configured to receive a virtual machine data file that includes an operating system, a web server, a content playback application, and a test program. The virtual machine data file is executed to cause the operating system and web server to initialize. The web server detects a communications connection to the client, transmits the content playback application to the client for execution, and transmits one or more tests included in the test program to test the audio/video playback capabilities of the client. The computing device is further configured to receive, from the client via the web server, test results associated with the one or more tests, and to store the test results in a memory.
