Claim:
1. A method of encoding video data, the method comprising: determining, for a current picture of the video data, one or more least significant bits of a picture order count value that directly identifies a long-term reference picture to be used when encoding at least a portion of the current picture; when one or more least significant bits of any other picture order count values that identify any other picture stored to a decoded picture buffer to which the long-term reference picture is also stored are the same as the determined one or more least significant bits of the picture order count value, determining one or more most significant bits of a delta of the picture order count value directly identifying the long-term reference picture and a picture order count value directly identifying the current picture; specifying both the determined one or more least significant bits and the determined one or more most significant bits in a bitstream representative of an encoded version of the video data; and encoding at least the portion of the current picture using the long-term reference picture.
