Presented herein are system(s), method(s), and apparatus for dynamic blanking. In one embodiment, there is presented a method. The method comprises generating blank lines forming a portion of a larger picture if a picture is not available, until the picture is available; and including the picture in the larger picture when the larger picture is available.

Video system and method supporting display of different size pictures

Disclosed herein is a method and apparatus for preventing and eliminating undesirable effects in displayed video. The method may include receiving video information and decoding the video information. The method may also include processing the number of illuminable lines associated with a video frame and blanking a remainder of the illuminable lines. Blanking the remainder of the illuminable lines may prevent and eliminate undesirable effects in the displayed video. The illuminable lines may be processed, such that each field may comprise an even number of corresponding, illuminable lines. The fields, however, are not required to have the same number of lines. In an embodiment according to the present invention, no active lines in one field may be below a blanked line in a corresponding field. The apparatus may include a video processor including a video post-processing unit adapted to determine a number lines to be illuminated on a particular video display device and a number of lines to be blanked in order to prevent and eliminate undesirable effects in the displayed video.

Post-processor design supporting non-flickering interlaced display

Methods and systems for processing pixels within a decoded video stream are disclosed. Processed pixels may be received within the decoded video stream and may be buffered in a buffer at a first rate. The buffered received processed pixels may be transferred out of the buffer at a second rate, where the first rate is greater than said second rate. The buffering of the received processed pixels and the transferring of the buffered received processed pixels out of the buffer may be monitored to prevent an overrun of the buffer. The first rate of the buffering of the received processed pixels may be reduced to prevent the overrun of the buffer. The second rate of the transferring of the buffered received processed pixels out of the buffer may be monitored to prevent the overrun of the buffer. Amount of the buffered received processed pixels within the buffer may be determined.

Buffer for driving display with asynchronous display engine

This invention provides rate shaping in per-flow output queued routing mechanisms for unspecified bit rate service.

Rate shaping in per-flow output queued routing mechanisms for unspecified bit rate service

A network infrastructure comprises a number of connective devices (routers, repeaters, bridges, etc.) to form a communication network for a plurality of end nodes. Message packets originating with an end node are assigned an input virtual network and workgroup identification at the port at which the packet enters the network. This assigned input virtual network and workgroup identification is compared, at each port from which the packet can exit the network infrastructure, with output virtual network and workgroup identification assigned the particular port. If the input virtual network information does not match the output virtual network information, the packet is prohibited from exiting that port. Even if there is a match between the input and output virtual network information, there must also be a match between at least one bit of the input workgroup identification and the output workgroup identification before the packet can exit the port.

Rate shaping is provided in per-flow queued routing mechanisms for available bit rate service. A traffic shaper in a packet switched communications system serially emits packets of time multiplexed flows in substantial compliance with individual network traffic contracts for the respective flows. The individual network traffic contracts include contracts which specify respective peak packet emission rates and associated peak rate tolerances for certain of the flows and which cause each of the flows to fall into mutually exclusive categories. The traffic shaper includes a queuing mechanism and a scheduling mechanism. The queuing mechanism organizes pending packets of active flows, including the certain flows, in respective queues in accordance with an oldest pending packet at head of queue order. The scheduling mechanism is coupled to the queuing mechanism for scheduling the packets of the active flows for emission. The scheduling mechanism includes a relatively high priority non-work conserving calendar queue, at least one relatively low priority work conserving queue, and another non-working conserving calendar queue of indeterministic priority relative to the high and low priority queues. The scheduling mechanism can also include a control mechanism for monitoring emissions from the high and low priority queues and for selectively descheduling packets scheduled on the high and low priority queues.
