A system utilizes a high throughput coding mode for CABAC in HEVC. The system may include an electronic device configured to obtain a bit stream; determine whether to decode level information of the sub-block of a block from the bit stream by using a first or a second decoding based on a characteristic of the sub-block; if the characteristic of the sub-block satisfies a predetermined condition, decoding level information of the sub-block from the bit stream by using the first decoding, and if the characteristic of the sub-block does not satisfy the predetermined condition, decoding level information of the sub-block from the bit stream by using the second decoding that is different from the first decoding.

A high-speed Ethernet apparatus having a multiple lane configuration and method for selectively operating the multiple lanes to allow lanes to participate or not in data transmission and reception. The Ethernet apparatus includes: a transfer rate control unit to set a state of each of multiple physical coding sub-layer (PCS) lanes inside to be the same as a state of corresponding each of multiple physical transmission lanes based on state change information that indicates whether the each physical transmission lane is activated or not, and to remove idle blocks from data blocks which are received at a transfer rate of a physical transmission lane in active state among the multiple physical transmission lanes; and a block allocating unit to allocate the data blocks from which the idle blocks have been removed through PCS lanes in active state that correspond to the physical transmission lanes in active state.

A system utilizing high throughput significance map processing for CABAC in HEVC is described. 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.

An electronic device configured for fixed intra run-level mode is described. The electronic device includes a processor and instructions stored in memory that is in electronic communication with the processor. The electronic device obtains a symbol, e.g. a run-lev pair. The electronic device determines whether a fixed intra run-level mode condition is met. If the condition is met, the electronic device uses fixed intra run-level mode to determine a ‘cn’ value for the symbol. If the condition is not met, the electronic device does not use the fixed intra run-level mode to determine the ‘cn’ value for the symbol. The electronic device run-level codes at least a portion of video data based on the determined ‘cn’ value.
