Video coding using scatter-based scan tables
Scatter-based scan tables are used to encode and decode video streams. Scatter scan patterns transform coefficients between positions within a 2D array representing a block of a frame and positions within a 1D array for further encoding. By calculating a probability of whether a transform coefficient at a given position in a 2D array is non-zero, a scan order of the 2D array may be defined by a 1D array that groups the values most likely to be zero at the end of the 1D array for removal from a subsequent encoding process. This can reduce the amount of data in an encoded video stream. A decoder can use the same scatter scan pattern to rearrange a sequence of encoded transform coefficients in a 1D array into a 2D array for further decoding of an encoded block. |

Avoiding delayed data
Roughly described, a network interface device receiving data packets from a computing device for transmission onto a network, the data packets having a certain characteristic, transmits the packet only if the sending queue has authority to send packets having that characteristic. The data packet characteristics can include transport protocol number, source and destination port numbers, source and destination IP addresses, for example. Authorizations can be programmed into the NIC by a kernel routine upon establishment of the transmit queue, based on the privilege level of the process for which the queue is being established. In this way, a user process can use an untrusted user-level protocol stack to initiate data transmission onto the network, while the NIC protects the remainder of the system or network from certain kinds of compromise. |
