Abstract: Provided are techniques for low complexity video coding. For example, a video coder may be configured to calculate a first sum of absolute difference (SAD) value between a coding unit (CU) block and a first corresponding block in a reference frame, and define branching conditions for branching of CU sizes based on the first SAD value, the branching conditions including a background condition and/or a homogeneous condition. The video coder may be configured to detect the background condition if the first SAD value of the CU block is less than a first threshold background value, and detect the homogeneous condition if a second SAD value of a sub-block of the CU block is between upper and lower homogeneous threshold values based on the first SAD value. The branching of the CU sizes may be based on detecting the background or homogeneous conditions.

Abstract: An apparatus for coding video information according to certain aspects includes a memory unit and a processor in communication with the memory unit. The memory unit stores video information of a base, or reference, layer and an enhancement layer. The processor determines whether a base layer reference index is valid for the enhancement layer, and resolves mismatches between base layer and enhancement layer reference indices and reference frame picture order counts. Resolving mismatches may comprise deriving valid reference information from the base layer, using spatial motion information of video data associated with the reference information of the base and/or enhancement layers.

Abstract: A method of coding delta quantization parameter values is described. In one example a video decoder may receive a delta quantization parameter (dQP) value for a current quantization block of video data, wherein the dQP value is received whether or not there are non-zero transform coefficients in the current quantization block. In another example, a video decoder may receive the dQP value for the current quantization block of video data only in the case that the QP Predictor for the current quantization block has a value of zero, and infer the dQP value to be zero in the case that the QP Predictor for the current quantization block has a non-zero value, and there are no non-zero transform coefficients in the current quantization block.
