    IPC: G06F15/16

    Abstract: Methods and apparatus for packetization of content for transmission over a network. A method is provided that includes generating one or more content packets from the multimedia content, wherein the content packets are associated with a time reference, and adding a sync header to the one or more content packets to form one or more application layer packets, respectively, wherein the sync header comprises a time indicator that indicates time relative to the time reference. An apparatus includes encoding logic configured to generate one or more content packets from the multimedia content, wherein the content packets are associated with a time reference, and packetization logic configured to add a sync header to the one or more content packets to form one or more application layer packets, respectively, wherein the sync header comprises a time indicator that indicates time relative to the time reference.

    IPC: H04L12/18

    Abstract: Methods and apparatus to provide a virtual network interface. In an aspect, a method includes receiving a request to access content on a Non-IP network, wherein the request comprises an IP address and a quality of service (QoS) profile associated with the content, mapping the IP address and the QoS profile into a Non-IP network content identifier, and obtaining the content from the Non-IP network based on the Non-IP network content identifier. In an aspect, an apparatus includes an application interface configured to receive a request to access content on a Non-IP network, wherein the request comprises an IP address and a QoS profile associated with the content, mapping logic configured to map the IP address and the QoS profile into a Non-IP network content identifier, and processing logic configured to obtain the content from the Non-IP network based on the Non-IP network content identifier.

    IPC: G06T9/00 ,  H04B1/69

    Abstract: Video images in, e.g., a multimedia stream are scanned prior to compression for transmission to recognize symbols, such as graphics symbols and alpha-numeric characters. The types, positions, sizes, etc. of the symbols are recorded to render symbol information, and then the images are compressed with or without compressing the symbols, which may be removed from the images prior to compression if desired. The compressed video and symbol information are sent to a receiver, which decompresses the video, optionally transforms the symbols, and then inserts the symbols where indicated by the symbol information.

    Abstract: A method and apparatus for accurately determining the operating characteristics or impact of nonlinear effects on devices or communication systems transferring orthogonally coded spread-spectrum communication signals. A Walsh Power Ratio, is used to more accurately determine system response. This information can be used by power control loops in controlling or adjusting the operation of nonlinear elements or stages such as high power amplifiers in orthogonal CDMA communication systems to provide improved system response. The information can also be employed in assigning channels to systems users, and to proceed with physical changes to system hardware. The measurements used to formulate the WPR can be made to individual components or to entire systems by injecting communication signals in multiple channels containing data, and leaving at least one empty channel. The received power per channel on the output side of the system or device is then measured. A ratio of power density for the empty to the active channels is then formed. The determination of WPR for a system or components can be realized during periods of operation through periodic transfer of test signals either at allocated times or by interleaving among existing traffic signals in the system.
