20080240604 | Performing deblocking on pixel data - In one embodiment, the present invention includes a method for receiving pixel data for a portion of an image including a blocking artifact, calculating an artifact strength based on a difference between a two pixels on opposite sides of the blocking artifact, performing a local adaptability check using the artifact strength and values multiple pixels on the opposite sides, performing deblocking based on a result of the local adaptability check, applying a soft threshold to the artifact strength to adjust a value of the artifact strength, and re-aligning one or more pixels on the opposite sides based on the original value of the pixels and a pixel index value. Other embodiments are described and claimed. | 10-02-2008 |

20110242424 | Detecting Video Format Information in a Sequence of Video Pictures - Gradient analysis may be utilized to determine frame and field repeat patterns in input video data. Those frame and field repeat patterns may then be analyzed to match them with characteristic patterns associated with telecine 3:2 and 2:2 pulldown video data, for example. In addition, a progressive detector may use combing analysis to determine whether or not a particular field is progressive or interlaced data. Then, this information, together with a field flag which indicates whether field or frame analysis is appropriate, may be utilized to distinguish telecine 2:2 or 3:2 pulldowns and interlaced and progressive data in some embodiments. | 10-06-2011 |
20140050268 | METHOD AND APPARATUS FOR ADAPTIVELY REDUCING ARTIFACTS IN BLOCK-CODED VIDEO - Apparatus, systems and methods for adaptively reducing blocking artifacts in block-coded video are disclosed. In one implementation, a system includes processing logic at least capable of deblock filtering at least a portion of a line of video data based, at least in part, on edge information and texture information to generate at least a portion of a line of deblocked video data, and an image data output device responsive to the processing logic. | 02-20-2014 |

20130031615 | SYSTEM AND METHOD FOR WLAN ROAMING TRAFFIC AUTHENTICATION - A system and method for recognising traffic generated from an authenticated a device roaming in a wireless local area network and related aspects are provided. An authentication server is arranged to authorise communications traffic originating from a wireless access point to use a roaming service, the traffic comprising an NAT translated IP address. The server first authorises a WLAN roaming device, and then processes a meta-data message received from a WLAN access point in which the source address of the message comprises the source address of the roaming device at the WLAN access point. The server then determines, from the information provided in the meta-data message when it is received by the authentication server, which includes at this point a NAT translated source address in the meta-data message what the NAT translated source address of traffic from said NAT translated source address. In this way, all traffic generated by the roaming device whilst that NAT translated IP address is valid is automatically authorised to use a roaming service to access the internet. | 01-31-2013 |

The server then determines, from the information provided in the meta-data message when it is received by the authentication server, which includes at this point a NAT translated source address in the meta-data message what the NAT translated source address of traffic from said authenticated roaming device will be. This enables the authentication server to authenticate internet-bound traffic having said NAT translated source address. In this way, all traffic generated by the roaming device whilst that NAT translated IP address is valid is automatically authorised to use a roaming service to access the internet. | 12-18-2014 |
