Abstract:
The present technology relates to an encoding device and an encoding method capable of reducing the amount of information relating to information that specifies a reference image. An encoding unit generates a predicted image using a reference image. A transmission unit transmits inter_ref_pic_set_prediction_flag representing whether reference image specifying information specifying the reference image of a prior image that is an image prior to a current coding image in coding order is used as the reference image specifying information of the current coding image in a case where the current coding image is an image other than a first image of a GOP (Group of Picture). The present technology, for example, can be applied to an encoding device of an HEVC (High Efficiency Video Coding) system.

Claim (Index 4):
An encoding method, the encoding method comprising:\n encoding a syntax element in a sequence parameter set (SPS) of a plurality of pictures to be encoded, the syntax element being an indicator of a number of short-term reference picture set specifying information (short-term RPS specifying information) included in the SPS; in a slice header of a current picture of the plurality of pictures, setting a value of an index of a short-term RPS of the current picture equal to the number of short-term RPS specifying information included in the SPS; in a case when the index of the short-term RPS of the current picture is not equal to zero,\n setting, by circuitry, a value of a reference picture set prediction flag (RPS prediction flag), wherein the value of the RPS prediction flag is set to either a first value indicating short-term RPS specifying information included in the SPS, which precedes the current picture, is used to predict a short-term RPS specifying information of the current picture, or set to a second value indicating short-term RPS specifying information included in the SPS is not used to predict the short-term RPS specify information of the current picture, wherein the short-term RPS specifying information of the current picture being information specifying a reference picture set used to generate a prediction picture for the current picture, and \n encoding, by the circuitry, the value of the reference picture prediction flag; \n in a case when the index of short-term RPS of the current picture is equal to zero,\n setting the value of the RPS prediction flag to the second value indicating short-term RPS specifying information included in the SPS is not used to predict the short-term RPS specify information of the current picture, and \n precluding encoding the value of the RPS prediction flag.
