摘要： A method and apparatus to improve error resiliency in processing a multimedia bitstream is described. A directory of header information is generated for a multimedia bitstream. The directory information comprises packet header information associated with the multimedia bitstream. The directory information may be transmitted to a receiver along with the multimedia bitstream. A receiver of the multimedia bitstream and the directory can utilize the header information to identify and locate packets within and subsequent to erroneous data in the received bitstream. By identifying and locating packets that may otherwise be discarded, the receiver may be able to improve error recovery and decoding of the multimedia data.

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.
