Abstract: In an example, an electronic device of a decoder is configured to obtain a bit stream and recover a binary symbol from the obtained bit stream. The electronic device is configured to determine whether the binary symbol is to be decoded using a modified transform skip mode. The electronic device is configured to, in response to determining that the binary symbol is not to be decoded using the modified transform skip mode, determine a first TS_Shift value, and recover video data using the first TS_Shift value. The electronic device is configured to, in response to determining that the binary symbol is to be decoded using the modified transform skip mode, determine a second TS_Shift value, and recover video data using the second TS_Shift value.

Abstract: A system utilizing high throughput significance map processing for CABAC in HEVC is provided. The system includes a first and second electronic device. The first electronic device encodes a block of level values, and transmits a bitstream to the second electronic device based on the encoding. The second electronic device decodes the bitstream using a high throughput significance map processing technique in order to recover video data corresponding to the block.

Abstract: A system utilizing a high throughput residual coding mode for CABAC in HEVC is described. The system may include an electronic device configured to obtain a bitstream; recover a binary symbol from the obtained bitstream; determine whether the binary symbol is to be decoded using a high throughput residual coding mode; in response to determining that the binary symbol is not to be decoded using the high throughput residual coding mode, use a first coding technique to obtain a block of Transformed and Quantized Coefficients (TQCs); and, in response to determining that the binary symbol is to be decoded using the high throughput residual coding mode, use a second different coding technique to obtain a residual sample.
