20120264372 | METHOD FOR CONTROLLING WIRELESS PRINTING JOB AND PRINTER - A printer includes a memory module, a transceiver module, a processor and a print engine. The memory module stores one or more file(s). The transceiver module transmits information pertinent to the file(s) stored in the memory module to a peer electronic device and receives a print request carrying information pertinent to one or more file(s) selected to be printed from the peer electronic device. The processor obtains the information pertinent to the file(s) stored in the memory module and passes the information pertinent to the file(s) to the transceiver module, receives the print request from the transceiver module and processes the received print request, and issues a print command for printing the selected file(s) in response to the received print request. The print engine prints the selected file(s) in response to the print command. | 10-18-2012 |
20120265791 | FILE MANAGING METHOD AND MECHANISM - A file managing method and a file managing mechanism for processing files from a first electronic device on a second electronic device are provided. The file managing method comprises steps of: detecting whether the first electronic device is connected to the second electronic device; uploading a file to be processed from the first electronic device to the second electronic device while the first electronic device being connected to the second electronic device and being operated by inputting a command for processing the file on the first electronic device; sending the command to the second electronic device; and performing the command on the uploaded file by the second electronic device. | 10-18-2012 |
Patent application number | Description | Published |
20110142129 | MPEG VIDEO RESOLUTION REDUCTION SYSTEM - An MPEG video resolution reduction system includes an MPEG decoder, a down-sampler, and a partial MPEG re-encoder. The MPEG decoder decodes an input resolution MPEG stream to an input resolution baseband, and determines coding information from decoding the input resolution MPEG stream. The down-sampler down-samples the input resolution baseband to a reduced resolution baseband. The partial MPEG re-encoder uses the coding information to encode the reduced resolution baseband to a reduced resolution MPEG stream. | 06-16-2011 |

20130039417 | RESIDUAL TREE STRUCTURE OF TRANSFORM UNIT PARTITIONING - In one embodiment, a method includes receives a prediction unit (PU) for a coding unit (CU) of video content. The PU is partitionable into a plurality of PU partition types. The method determines a PU partition type for the PU and a residual tree structure based on the PU partition type for partitioning of the CU into transform units (TUs). The residual tree includes a binary partition of a node into two. A TU partition for the PU partition type is determined based on the residual tree structure and a desired level of partitioning in the residual tree structure. The method then uses the TU partition in a transform operation. | 02-14-2013 |
20130064290 | METHODS AND APPARATUS FOR QUANTIZATION AND DEQUANTIZATION OF A RECTANGULAR BLOCK OF COEFFICIENTS - A system includes an encoder that performs quantization on a rectangular block of quantized transform coefficients and a decoder that performs dequantization on a rectangular block of transform coefficients. The decoder is configured to receive a W×H block of quantized transform coefficients, wherein W is a row width of the block and H is a column height of the block.

20140029670 | DEVICES AND METHODS FOR PROCESSING OF PARTITION MODE IN HIGH EFFICIENCY VIDEO CODING - Disclosed is a method for providing a reduced number of bits to represent partition modes in certain instances for High Efficiency Video Coding. A single conditional statement is evaluated once to determine if asymmetric motion partitioning (“AMP”) may be used in a current coding tree block. When an AMP flag indicates that AMP is not enabled, then a two-bit codeword is encoded or decoded for an inter-mode partition of the current coding tree block in a bitstream. | 01-30-2014 |
