A method to interact with a remote USB device is disclosed. An identifying message is received from a remote client associated with the remote USB device. The remote USB device is identified based at least in part on the identifying message from the remote client. A security policy is determined for the remote USB device. A policy message is transmitted to the remote client for selectively implementing the security policy of the remote USB device. A method to interact with a local USB device is disclosed. An identifying message is determined by performing a host controller service for the local USB device. The identifying message is transmitted to a server. A policy message is received from the server for selectively implementing a security policy on the local USB device. The security policy is regarded and configuring the host controller service.

Universal serial bus selective encryption

A system for executing video encoding operations. The system includes a video encoder for encoding an incoming video stream into a plurality of macro blocks. A motion estimation engine is coupled to the video encoder for controlling the encoding of the macro blocks. A video rate control processor is coupled to the video encoder and coupled to the motion estimation engine. The video rate control processor receives a plurality of parameters from the video encoder that indicate an encoding complexity for a macro block and a video frame of the video stream and, upon receiving an indication from the motion estimation engine, computes a quantization parameter for the macro block. The quantization parameter is dynamically adjusted for the video stream to achieve a target bit rate.

Video rate control processor for a video encoding process

A method to interact with a local USB device is disclosed. Messages are transmitted to a remote host controller driver from a host controller associated with the local USB device. Messages are received from the remote host controller driver for the host controller. In some embodiments, a transfer descriptor prototype is received from the remote host controller driver. A completed transfer descriptor is received from the remote host controller driver. The completed transfer descriptor and the transfer descriptor prototype are transformed into a modified transfer descriptor in part by using a collection of rules. The modified transfer descriptor is submitted to the local host controller without intervention from the remote host controller driver.

Universal serial bus host controller driver over a network

A method to interact with a local USB device is disclosed. A message is received from the local USB device. Predetermined information is extracted from a proper subset of the message. The extracted information is transmitted to a local process.

Universal serial bus assistance engine

A method for executing video encoding operations. The method includes encoding an incoming video stream into a plurality of macro blocks by using a video encoder and receiving a box out slice map specification for the plurality of macro blocks. The box out slice map specification is converted to a foreground-background slice map specification. The plurality of macro blocks are then processed in accordance with the foreground-background specification and by using a common hardware encoder front end.
