  • Patent number: 11516492
    Abstract: Some embodiments include a method of signaling picture count information for decoding video pictures. The method sends a picture order count (POC) most significant bit (MSB) first flag indicating that a picture order count most significant bit second flag is present. The method sends the POC MSB second flag to indicate whether a POC MSB cycle element is present. When a value of the POC MSB present flag is true, the method sends the POC MSB element specifying a value of a POC MSB cycle.

    Abstract: A method of signaling picture count information is disclosed. A picture order count most significant bit present flag and a picture order count most significant bit cycle element are sent. The picture order count most significant bit present flag indicates whether a picture order count most significant bit cycle element is present. The picture order count most significant bit cycle element specifies a value of a picture order count most significant bit cycle if a value of the picture order count most significant bit present flag is equal to one. A maximum value of the picture order count most significant bit cycle element is set by using a maximum picture order count least significant bit minus four element.
