摘要： A method for transmitting device indicator data in a network-based AV system is provided. The method for transmitting the device indicator data records device indicator data on a data unit which is used in an AV transmission protocol, and transmits the data unit. Accordingly, the indicator data which changes in real time in a network AV device can be rapidly transmitted to a management platform.

摘要： A segment synchronization method of a network-based display is provided. The network segment synchronization method forms a plurality of network segments, selects a single terminal in the network segment as a segment master, sets the other terminals in the network segment as segment slaves, and synchronizes, by the segment slaves, time to the segment master of the network segment to which the segment slaves belong. Accordingly, a function of synchronizing can be provided to super multi-view network terminals without a bridge (switch) providing an existing gPTP function for each port.

摘要： An apparatus includes: first to N−1-th correlation-calculation units correlation-calculating a signal at a position corresponding to an n-th reference cell of a reference symbol in a received symbol and a signal at a position corresponding to an n+1-th reference cell of the reference symbol in the received symbol; a first calculation unit multiplying a result of phase correlation calculation of the n-th reference cell and the n+1-th reference cell by the calculation result of the correlation-calculation units and thereafter, summing up all of the multiplication results to calculate a first sum total; a second calculation unit multiplying a result of phase correlation calculation of an N−n−2-th reference cell and an N−n−1-th reference cell by the calculation result of the correlation-calculation units and summing up all of the multiplying results to calculate a second sum total; and a decider detecting a larger value between the first and the second sum total.
