Abstract: An image analyser analyses regions of an image. An image sealer may then scale the image adaptively, in dependence on the nature of region of the image being scaled. In one embodiment, adjacent pixels are analysed to determine their frequency content. This frequency analysis provides an indication of whether the pixels likely contain hard edges, discontinuities or variations typical of computer generated graphics. As a result of the analysis, the type of scaling suited for scaling the image portion containing the pixels may be assessed. Adjacent pixels having high frequency components may be scaled by a scaling circuit that introduces limited ringing. Adjacent pixels having lower frequency components may be scaled using a higher-order multi-tap scaler. Resulting scaled pixels may be formed as a blended combination of the two different scaling techniques.

Abstract: A method of signal processing according to one of several embodiments includes estimating a deterministic component of a received signal. The estimating is based on an estimated response of a transmission channel. Based on the estimated deterministic component, a non-deterministic component of the received signal is estimated. Based on corrupted portions of the estimated non-deterministic component, a noise estimate is obtained, and the received signal is compensated based on the noise estimate. A method according to another embodiment includes replacing received samples at corrupted locations with values from a calculated model.

Abstract: A system and method for transmitting client phase information to a host device over a bidirectional data link is described. Embodiments include detecting a phase of a clock signal relative to a data signal transmitted between a host device and a client device over a bidirectional data link. The data link includes one or more data lines each configured to transmit a corresponding bit of the data signal. The phase is encoded as client phase information and transmitted between the host and client device over the one or more data lines. The client phase information is transmitted during an electrical turnaround time period of the bidirectional data link between a read and write operation over the data link.

Abstract: To derive a Hamming code to manage data errors a set of at least four parity bit positions is selected for parity bits which will protect a set of data bits (where each data bit has a data bit position in the data bit set). A syndrome is determined for each data bit position. This involves selecting a unique sub-set of at least three parity bit positions. The unique sub-set shares at least one parity bit position with at least one other unique sub-set of at least three parity bit positions. A parity bit value may then be calculated for each parity bit position based on the determined syndromes. The header of a packet may be provided with a word which defines the length of the packet and an error management code generated utilizing this word so that errors in the word may be detected and, possibly, corrected.

Abstract: A method and apparatus for communicating compressed video information includes storing video information compressed based on a first compression method, such as a method with a high compression ratio, and transcoding the compressed video information to produce corresponding recompressed video information that is based on a second compression method, with a lower compression ratio such as standard JPEG compression or other suitable compression. The method and apparatus, if desired, may include sending the recompressed video information for a destination apparatus which may then suitably decompress the video information using a standard decompression technique. For example, storing the compressed image in a high compressed format, for example, in a piecewise basis may be done online while the camera, for example, is in use so that the image is properly captured and then, transcoding the compressed image to a different level of compression while the camera is offline.

Abstract: A system and method for frame synchronization in multiple video processing unit (VPU) systems is described. In various embodiments, multiple VPUs cooperatively process frame data for display. According to embodiments, more than one VPU may not reside on a same card such that conventional synchronization methods are available. Frame data synchronization is accomplished in various embodiments by using semaphore mechanisms and by writing values to shared memory locations. For synchronization of execution among multiple VPUs operating on a same command buffer, execution of commands by one or more VPUs is stalled based on a semaphore value or a value in a shared memory location.
