    摘要: A computer-readable carrier medium in wireless station for wireless network. Encoded in the carrier medium are instructions that when executed carry out a method operating at the link layer (L2) in the wireless station. The method includes, prior to the station being associated with a wireless network, wirelessly receiving L2 frames transmitted from one or more wireless access point of one or more wireless networks that the station can hear. The method further includes gathering information about the received L2 frames, including L2 information and L3 information. The L3 information includes whether an access point is sending an IP packet from a mobility agent, such that the station may associate with a wireless network that is in communication with the mobility agent. The method further includes storing information about the wireless networks that the station can hear in a database. The information stored about each wireless network includes one or more of an identifier of the wireless network, the L3 information in the L2 frame received from the access point of the wireless network, a time stamp of when the L2 frame was received from the access point, and an indication of the signal strength of the L2 frame from the access point.

    摘要: A video codec that allows for improved performance of embedded devices using vector quantization and the high correlation between frames in a scene to reduce the overhead associated with displaying video data. Video coding includes determining scene changes in a movie, producing one codebook for each scene, and coding each frame within a scene with the same codebook. The quantized video data is then losslessly compressed and formed into a video stream. Video decoding includes decoding the codebook for a frame and supplying the codebook and frame indices for frame rendering. Alternatively, video coding also includes dividing CPU time between codebook processing, indices processing, and frame rendering to ensure smooth video output.

    摘要: A method, an apparatus and a carrier medium for securely distributing multimedia while still retaining compatibility with existing CA systems. The method includes forming a packet including a plurality of encrypted multimedia stream segments. The packet further includes, for each segment of the plurality, a field providing conditional access information associated with the segment. The method further includes sending the packet to an intermediary. The method is such that the intermediary receiving the packet can send a first segment of the plurality and any associated conditional access information to a first receiver, and send a second segment of the plurality and any associated conditional access information to a second receiver. The method is also such that no decryption of any segment of the plurality is required by the intermediary to send the first segment or to send the second segment.

    摘要: A method and a carrier medium instructing a processor to execute a method. The method includes accepting a compressed video stream compressed by a compression method that uses macroblocks of possibly different macroblock types for each frame predictive encoding frames. The method further includes identifying a sequence of frames that are substantially visually indistinguishable and that include a predictively encoded frame and the at least one reference frame of the predictively encoded frame. The method further includes creating an ordered set of macroblocks, with the macroblock types of different macroblocks in the ordered set used to encode digital watermark information. The method further includes replacing the predictively encoded frame of the identified sequence with a newly-encoded predictively encoded replacement frame that contains the created ordered set of macroblocks, including the encoded watermarking information.

    摘要: An apparatus, a method and a computer program product for correcting image data for the presence of a ghost image. The image data is for acceptance by a device that includes a partially-silvered finite-thickness reflector or similar element to provide a reflection of an image for display. The ghost image is a shifted, attenuated version of the image data. The method includes subtracting a first correction term from the image data, the first correction term being a shifted and attenuated version of the image data, the shift being the same as that between the image data and the ghost image, and the attenuation matching the attenuation of the ghost image caused by the device. The processed image data is input to the device. For a small enough attenuation of the ghost image, substantially no ghost image of the image data is displayed by the device.

    摘要: A method to process audio signals, an apparatus accepting audio signals, a carrier medium that carried instructions for a processor to implement the method to process audio signals, and a carrier medium carrying filter data to implement a filter of audio signals. The method includes filtering a pair of audio input signals by a process that produces a pair of output signals corresponding to the results of: filtering each of the input signals with a HRTF filter pair, and adding the HRTF filtered signals. The HRTF filter pair is such that a listener listening to the pair of output signals through headphones experiences sounds from a pair of desired virtual speaker locations. Furthermore, the filtering is such that, in the case that the pair of audio input signals includes a panned signal component, the listener listening to the pair of output signals through headphones is provided with the sensation that the panned signal component emanates from a virtual sound source at a center location between the virtual speaker locations.
