摘要： 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.

摘要： A system and method for the detection of zero-rate communication frames on forward and reverse communication links is described herein. In a first embodiment, the rate determination process begins upon receiving pilot and traffic channel signals. The system then compares the received traffic channel energy with the pilot signal to obtain a metric. The metric is then compared with a predetermined threshold to detect the presence of a zero-rate traffic channel frame. In a second embodiment, the process begins with the receipt of a reverse communication link frame having first and second portions. The system then detects the energy contained in the first and second portions. The system compares the detected energy in the first portion with the detected energy in the second portion to obtain a metric. The system then compares the metric with a predetermined threshold to detect the presence of the zero-rate frame. The selection of the predetermined threshold in both embodiments is based on the probability of detection of a transmitted zero-rate frame and the probability of erroneously detecting a zero-rate frame.

摘要： Systems, apparatus and methods provide an automatic capability for generating interactivity event applications for execution on receiver devices within a broadcast network based upon interactivity event application data, information and sequence logic. Interactivity event content providers may provide to a broadcast network interactivity event application data, event metadata information and sequence logic a broadcast network. Interactivity application data for an interactive sequence may be delivered out-of-band, such that the application data is not embedded in an interactivity event. Interactivity sequence application data may be sent out-of-band from the associated interactivity event signaling message. Application data may be sent on a different transport channels in advance of the interactivity event. The system may determine when data should be sent out-of-band and when it should be sent in-band.

摘要： 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.
