Abstract: Techniques are provided herein to produce encoded video bitstreams and to similarly decode encoded video bitstreams according to a coding standard not supported by an on-chip encoder/decoder. For purposes of encoding, a video sequence is received at a first device. A first bitstream is generated at the first device by encoding the video sequence according to a first coding standard and information associated with the video sequence is generated at the first device according to a second coding standard. The first bitstream and the information are then transmitted to a second device. At the second device the first bitstream is decoded to produce a second bitstream. The second bitstream and the information are combined by removing syntax elements associated with the first coding standard from the second bitstream and adding the information to produce a third bitstream according to the second coding standard. Similar techniques are provided for decoding an encoded bitstream to recover a video sequence.

Abstract: Systems and methods for delivering real-time video imagery to a receiver over a channel. A current video frame is captured and digitized. The digitized frame is divided into a plurality of macroblocks. For each macroblock an intra, inter or skip mode coding mode is determined. Based on instantaneous feedback received from a receiver regarding successfully received video packets for a prior video frame, a quantization parameter is set and the macroblocks are encoded in accordance with their respective selected coding mode. Synchronized error concealment is performed at both the encoder and decoder sides of the system and retransmission of lost video packets, using an adaptive retransmission scheme, are performed in accordance with the instantaneous feedback from the receiver.

In the systems and methods, a Universal Short Code (USC) Administrator maintains a list of short codes and their lease status so that SMS messages sent to a particular short code may be routed to the proper holder of the short code. A network facilitator is in communication with both the USC Administrator and at least one wireless carrier to route the SMS message to the proper holder of the short code. The short code may be leased for a specified period of time so that the short code can be reassigned after expiration of the lease.

Abstract: A database security overlay that identifies each network and local access gateway to a database, and monitors each access path from the identified gateways to analyze each connection to the database and block any connections determined to transport unauthorized or undesirable content. Access gateways that establish connections are identifiable by interprocess communication (IPC) mechanisms employed in accessing the database. An evaluator monitors access attempts, while a tapping mechanism on IPC mechanisms that provide the connections captures access attempts from the access gateways. The tapping mechanism intercepts and forwards access attempts to the evaluator to centralize and focus DB paths amid multiple local and external connections on the DB server. A lightweight check for each local access quickly determines if the access attempt warrants further scrutiny.

Abstract: Techniques are provided herein to enable monitoring of a real-time transport protocol (RTP) packet flow in devices along the path that the RTP packet flow traversed from a source to a destination. A device that is a source or destination of a RTP packet flow transmits a monitor request message that requests one or more other devices along a path of the RTP packet flow to monitor the RTP packet flow. The device that is the source or destination of the RTP packet flow receives one or more monitoring reports from the one or more other devices along the path of the RTP packet flow. This allows a device that requested monitoring of the RTP packet flow to analyze the monitor reports in order to determine a location of a cause of reduced performance in the RTP packet flow. e.g., missing packets, overly delayed packets, etc.
