Claim Text:
1. A method of decoding video data, the method comprising: decoding syntax element data for a plurality of pictures in a picture coding order, wherein the syntax element data indicates that each of the plurality of pictures is available for use as a long term reference picture; decoding a slice header for a slice of the video data, wherein the slice header includes a syntax element indicating a number of long term reference pictures derived from a sequence parameter set; determining whether a long term reference picture of the plurality of pictures is explicitly signaled in the slice header or derived from the sequence parameter set corresponding to the slice; when the long term reference picture is explicitly signaled, decoding the slice header further comprises decoding a value for identifying information for the long term reference picture in the slice header; and determining that a value for DeltaPocMSBCycleLt [i] of the long term reference picture having index value i is always equal to a value for a syntax element delta_poc_msb_cycle_lt_[i] of the long term reference picture having index value i when the long term reference picture has the index value i equal to the number of long term reference pictures derived from the sequence parameter set.
