    Abstract: Systems and methods are provided for identifying important video frames and segments in multimedia content such as a segmented compressed domain video. Video frames in a segment are analyzed to determine intensity, contrast, and motion values for the frames and their segments. The values among frames and segments are compared to identify one or more video segments likely to be important to a viewer. The systems and methods may additionally be augmented with audio data other characteristics associated with the video frames and segments analyzed.

    Abstract: A method comprises receiving a signal containing an environmental cue; correlating the environmental cue to a user interface control element; and generating a user interface control command based on the environmental cue. A device may be controlled by receiving a visual image, processing the image to identify a visual cue, correlating the visual cue with a user interface control, and controlling the device using the user interface control. The visual image may be received from a camera that is part of an automobile, and the user interface control may include a control for a radio to tune to a radio station; a speed control for controlling a speed of the automobile corresponding to a speed sign visual cue; or a navigation system control for controlling a navigation system based on traffic signs. Other variations include an apparatus and computer-readable media including instructions for performing the methods.

    Abstract: A method for reporting a streaming quality is shown, wherein at least one continuous media stream is streamed to a client (601), and wherein the streaming is controlled by a protocol (109) that is operated between the client (601) and a server (600), the method including selecting at least one quality metric and a quality metrics class from a pre-defined set of at least two quality metrics classes, and reporting to the server (600) the quality of the streaming based on the at least one selected quality metric and the selected quality metrics class. The protocol (109) is preferably a Real-time Streaming Protocol (RTSP) in combination with a Session Description Protocol (SDP) in the context of the 3GPP Packet-Switched Streaming Service (PSS). Also shown is a computer program, a computer program product, a system, a client, a server and a protocol.

    Abstract: An improved system and method for deinterleaving a data unit containing chunks of two or more different data types. In an embodiment of the invention, both a device MPU and DMA hardware are used to deinterleave a data unit containing chunks of both compressed data and uncompressed data. The device MPU is used to transfer compressed data from an interleaved data buffer to a compressed data buffer, while the DMA hardware is used to transfer uncompressed data from the interleaved data buffer to a compressed data buffer. By using both the MPU and the DMA hardware, the overall efficiency of the data transfer process is improved.
