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 wireless communications device is configurable to communicate with either one of two networks over a wireless medium, each of the two networks having a different air interface protocol. Additionally, the wireless device includes stored provisioning information for a set of networks of a first type and can map this first provisioning information into a second format for use with networks of a second type. The device also includes a non-volatile memory for storing default provisioning information so that some information remains available regardless of what is erased from the memory. The default provisioning information is enough to establish a connection over one of the available networks and allow reconstruction of a provisioning list.
