Abstract: Systems and methods are provided for evaluating composition of a first file representing a document to be evaluated. An evaluation method transforms the first file to a second file. The second file includes a plurality of objects corresponding to the composition of the first file. The evaluation method also determines parameters based on the plurality of objects; evaluates the parameters based on a plurality of composition rules provided by a rule engine; generates evaluation findings and stores the evaluation findings; and generates an evaluation conclusion based on the evaluation findings. The evaluation conclusion indicates compliance of the document according to the composition rules.

Abstract: Various embodiments for switching programs streams using a fixed speed program stream buffer coupled to a decoder are described. Various embodiments for switching programs streams using a fixed speed program stream buffer coupled to a decoder are described. In one or more embodiments, the fixed speed program stream buffer may be arranged to receive multiple program streams, such as video program streams, and to buffer historical frames comprising at least one anchor frame. Upon detecting a channel switch point, the most recent historical anchor frame prior to the channel switch point may be provided to the decoder. After receiving the anchor frame, the decoder may be arranged to start the next frame after the anchor frame instantly. Once the most recent historical anchor frame is played in to the decoder, the decoder may pick off the next frame after the anchor frame at a normal cadence.

Abstract: Various embodiments for switching programs streams using a variable speed program stream buffer coupled to a variable speed decoder are described. In one or more embodiments, the variable speed program stream buffer may be arranged to receive multiple program streams, such as video program streams, and to buffer historical frames comprising at least one anchor frame. The variable speed program stream buffer may be arranged to always comprise at least one anchor frame and may be implemented by running and/or elastic buffers corresponding to an active channel program stream and one or more alternate channel program streams. Upon detecting a channel switch point, the historical frames comprising the anchor frame up to the channel switch point may be provided to the variable speed decoder in an accelerated manner.

Abstract: A multiphase encoded protocol has sufficient density of commands to allow a rich language to be realized on a bus. When ten field bits are dedicated to commands, it is possible to have more than six million words to choose from per clock. Architecture to implement the multiphase encoded protocol and synchronize the bus includes an extracted clock, a command element, and a data element. One-bit multipliers are used as correlation elements to provide feedback into slaved delay-locked loop (DLL) devices, which provides precise phase alignment for successful data extraction of several channels.

Abstract: According to one aspect of the invention, a method is provided in which one or more requests are received to transmit data between a first device and a second device via a bus having a plurality of data lines.
