    Abstract: In general, the disclosure describes techniques related to block vector coding for Intra Block Copy and Inter modes. In one example, the disclosure is directed to a video coding device comprising a memory configured to store video data and one or more processors. The video coding device is configured to determine a reference picture used for coding the current video block and determine a picture order count (POC) value for the reference picture. In response to the POC value for the reference picture being equal to a POC value for a current picture that includes the current video block, the video coding device sets a value of a syntax element to indicate that a reference picture list includes the current picture. Otherwise, the video coding device sets the value of the syntax element to indicate that the reference picture list does not include the current picture.

    Abstract: An apparatus configured to encode video information of a picture includes a memory unit and a processor in communication with the memory unit. The memory unit is configured to store a hash table that includes at least one hash index corresponding to reference blocks in the picture, the reference blocks being a subset of available blocks in the picture. The processor is configured to map a current block to a hash index in the hash table based on the application of a hash function to the current block, identify, from the hash table, reference blocks that correspond to the hash index, select a prediction block from among the reference blocks based on a comparison of the current block to the reference blocks, and encode the video information using the selected prediction block.

    Abstract: In general, techniques are described for performing an intra block copying process to code video data. A video decoding device that includes a memory and one or more processors may perform the techniques. The memory may be configured to store a current block of a picture. The processors may be configured to perform an intra block copying process to decode the current block using a prediction block that is from a same slice or a same tile as that in which the coded current block resides, the prediction block restricted to be within a search region that only includes the same slice or the same tile as that in which the coded current block resides.
