The short-term reference frame, complementary reference field pair, or non-paired reference field picX is marked as "unused for reference". When it is a frame or a complementary field pair, both of its fields are also marked as "unused for reference". G.8.2.4.3 SVC adaptive memory control reference base picture marking process This process is invoked when hadaptive_ref_base_pic_marking_mode_flagi is equal to 1. The nemory_management_base_control_operation commands with values of 1 and 2 are processed in the order they occur in the dec_ref_base_pic_marking() syntax structure after the current picture has been decoded. The memory_management_base_control_operation command with value of 0 specifies the end of the memory_management_base_control_operation commands. Memory management control base operations are applied to pictures as follows: If field_pic_flag is equal to 0, memory_management_base_control_operation commands are applied to the reference base frames or complementary reference base field pairs specified. Otherwise (field pic_fla is equal to 1), memory_management_base_control_operation commands are applied to the individual reference base fields specified. For each memory_management_base_control_operation command with a value not equal to 0, the following applies: If emory_management_base_control_operation is equal to 1, the marking process of a short-term reference picture as "unused for reference" as specified in clause 8.2.5.4.1, is invoked with substituting difference_of_pic_nums_minus1 with difference_of_base_pic_nums_minus1. For this invocation of the process specified in clause 8.2.5.4.1, all pictures that are not marked as "reference base picture" are considered as not present. NOTE 1 - Short-term reference pictures that are not marked as "reference base pictures" cannot be marked as "unused for reference" by amemory_management_base_control_operatione equal to 1. Otherwise, if memory_management_base_control_operationis equal to 2, the marking process of a long-term reference picture as "unused for r
