Video decoding apparatus

摘要

According to an embodiment, a method of decoding encoded moving picture data may be provided. The method may include: computer implemented steps performed by a processor of a computer system to implement the following steps: decoding the encoded moving picture data into decoded pictures; storing the decoded pictures in a decoded picture buffer, wherein the decoded pictures in the decoded picture buffer include at least one reference picture and at least one non-reference picture; if a picture is an IDR picture, making unused for reference the at least one reference picture stored in the decoded picture buffer; if a flag associated with the IDR picture has a first value, deleting from the decoded picture buffer an decoded picture made unused for reference; and if the flag associated with the IDR picture has a second value, emptying the decoded picture buffer.
