    摘要: Systems and methods are directed to a memory device that includes a plurality of memory buffers and a direct memory access (DMA) descriptor structure. The DMA descriptor structure comprises a transfer command and associated data transfer information and encryption/decryption information that is configured in a two dimensional, tree-linked structure. A DMA controller that is communicatively coupled to the memory device transfers data to/from the memory buffers and encrypts/decrypts the data based on the transfer command and data transfer information and encryption/decryption information provided by the two dimensional, tree-linked DMA descriptor structure.

    摘要: Some demonstrative embodiments include devices, systems and/or methods of video encoding. For example, a device may include an encoding selector to control a block encoder to encode current video data of at least one pixel block of a current video frame, the encoding selector is to select between a first encoding mode causing the block encoder to encode the current video data into an encoded block to be provided to a decoder, and a second encoding mode allowing the block encoder to generate an indication to indicate to the decoder that the current video data is to be decoded using video data decoded from a previous video frame, wherein the encoding selector is to select between the first and second encoding modes without using previous video data of the pixel block of the previous video frame.

    摘要: Embodiments of wireless devices and methods to support a clock synchronization protocol that is provided independently and in parallel to multiple protocol abstraction level (PAL) and other upper layer entities and to multiple streams per each of the PAL and the upper layer entities. The frequency and time synchronization messages are delivered by MAC management action frames and can be aggregated in A-MPDU together with data, management and control MPDUs.

    摘要: In a wireless video system, the clock rate for wirelessly transmitting the video data from the transmitting device should be identical to the clock rate for receiving the video data at the receiving device. But the two devices have separate clocks, whose frequencies may drift apart over time, leading the video buffer to be over run or under run. Clock synchronizing messages to prevent this may be sent at short intervals when clock synchronization is first being acquired, and at larger intervals after clock synchronization has already been achieved and is merely being maintained.
