摘要： A resynchronization method for use in a data communication system having a first device configured to transmit data at a symbol rate to a second device. The second device includes a Reed Solomon (RS) decoder having a RS lock indicator and a Moving Picture Experts Group (MPEG) Protocol Interface (MPI) having a MPI lock indicator, wherein the RS and the MPI lock indicators are monitored. Four different states, defined by the values of the RS and MPI lock indicators, determine whether the data communication system will wait for the RS decoder and the MPI hardware block to resynchronize, whether an intermediate-subset of the channel acquisition algorithm is performed or whether the entire channel acquisition algorithm is performed. The method for resynchronization described herein recovers synchronization within a predetermined time without the layers above the physical link layer having knowledge.

摘要： In at least some embodiments, a system may comprise one or more devices configured to communicate according to a first protocol that uses a data frame comprising a header field and a data field and one or more devices configured to communicate according to a second protocol that uses a data frame comprising a header field, a header extension, and a data field. The data frame used by the second protocol may comprise fictitious information for interpretation by the one or more devices configured according to the first protocol. In accordance with some embodiments of the invention, the devices configured according to the first protocol may use the fictitious information to determine a data transmission duration of data packets sent by devices configured according to the second protocol, even though the data packets may be sent according to parameters that are not supported by the first protocol.
