1. A method, comprising:
obtaining quantized coefficients of a coding block;
obtaining a value of a first control flag, wherein the value of the first control flag equals to 1 indicates a first technique is to be used for the coding block, wherein the first technique comprises using a separate merge list for subblock merge candidates;
in response to determining the first technique is not used for the coding block, obtaining a value of a second control flag for the coding block, wherein the value of the second control flag equals to 1 indicates a second technique is to be used, wherein the second technique comprises multi-hypothesis prediction for intra and inter mode, wherein the value of the second control flag is transmitted when the first technique is not used for the coding block; and
encoding the quantized coefficients, the first control flag and the second control flag to obtain an encoded bitstream, wherein the second control flag is encoded when the first technique is not used for the coding block.
