The overall architecture and details of a scalable video fingerprinting and identification system that is robust with respect to many classes of video distortions is described. In this system, a fingerprint for a piece of multimedia content is composed of a number of compact signatures, along with traversal hash signatures and associated metadata. Numerical descriptors are generated for features found in a multimedia clip, signatures are generated from these descriptors, and a reference signature database is constructed from these signatures. Query signatures are also generated for a query multimedia clip. These query signatures are searched against the reference database using a fast similarity search procedure, to produce a candidate list of matching signatures. This candidate list is further analyzed to find the most likely reference matches. Signature correlation is performed between the likely reference matches and the query clip to improve detection accuracy.

A method and system is disclosed in which information related to an orientation or motion pattern of a mobile device system is detected. A determination is made whether the orientation information detected corresponds to a predetermined motion pattern or orientation for collecting event stamp information. The event stamp information may include a location and/or other event information. If the detected orientation and/or motion patterns is detected, the event stamp information is automatically collected in response to the determination, and the event stamp information is is at least temporarily stored.

Updates to landing pages of users in an online social network are fed from external sources so that content maintained by any one user can be consolidated in a single location regardless of where the changes are made to the content. When an update event occurs, users of the online social network are notified according to various criteria that they have set. With this feature, users can browse through content of other users efficiently.

Disclosed are various embodiments for synchronizing application state information across devices. More specifically, embodiments of the disclosure are related to facilitating idempotency of application state information. Idempotency is maintained by using a timestamp embedded within application state information and/or by determining that the application state information is associated with an accumulating value.

Systems and methods for managing packet flows in a communication network are provided. Packet information can be cached on different levels and used to avoid external queries. The cache information can also be correlated with other types of information, such as location information, to be able to serve that information quicker than if one or more external queries were to be made. A demux manager can provide routing and session setup, by routing packets that already have a session to the session manager and assigning packets to a session manager if they are not already assigned to a session. The tiered architecture also provides scalability to many users and minimizes delays even during high call volumes because the load can be distributed well across the gateway's resources.

A method is disclosed that includes receiving, from a device of a user, a request to transmit a multimedia file. The method also includes automatically generating a generated content descriptor based on an analysis of the multimedia file using at least one analysis parameter. The method includes determining whether the generated content descriptor satisfies filter criteria of a profile associated with the user. The method further includes rejecting the request to transmit the multimedia file when the generated content descriptor does not satisfy the filter criteria of the profile. The method includes transmitting the multimedia file along with the generated content descriptor when the generated content descriptor satisfies the filter criteria of the profile.

A first collection of content that includes digital assets is maintained on a host computer. Based on a determination that a portable media device becomes connected to a client computer that is separate from the host computer and that interacts with the host computer, initiation of a synchronization of the first collection of content resident on the host computer with a second collection of content on the portable media device is automatically triggered. The synchronization of the first collection with the second collection includes a transfer of at least one of the digital assets from the host computer to the client computer to the portable media device and is triggered and conditioned upon the determination that the portable media device has become connected to the client computer.
