Abstract: In a method for controlling data stored in an Solid State Disk (SSD) of a data de-duplication system, a storage controller obtains stability information of a data block. The stability information comprises a reference count of the data block and a length of a period of time when the data block is stored in the SSD. The storage controller identifies a stability level of the data block according to the stability information, and sends the stability level of the data block to the SSD. The SSD moves the data block to a target block which corresponds to the stability level. Thereby, the SSD can store data blocks having a same stability level together.

According to the method and the apparatus for controlling issuance of a PDP context in the embodiments of the present disclosure, issuance of a PDP context is controlled based on an issuance control condition of the PDP context, which can avoid generation of unnecessary traffic, improve service experience of a user, and reduce the customer service workload of an operator, thereby lowering the operating cost of the operator.

Abstract: A decoder receives a bitstream containing quantized coefficients representative of blocks of video representative of a plurality of pixels and decodes the bitstream using context adaptive binary arithmetic coding that includes at least two decoding modes, the first mode decoding the bitstream based upon a probability estimate which is based upon at least one of spatially and temporally adjacent syntax element values to a current syntax element being decoded, the second mode decoding the bitstream not based upon a probability estimate based upon other syntax elements to the current syntax element being decoded. The coding decodes the current syntax element using the first mode if the current syntax element is intra-coded and selecting between sets probable modes with different probabilities. The coding decodes the current syntax element using the second mode if the current syntax element is intra-coded and if selecting among one of the second set of probable modes.
