Patent number: 8249168Abstract: A system and method are disclosed for providing improved processing of video data. A multi-instance encoding module receives combined video and audio input, which is then separated into a video and audio source streams. The video source stream is pre-processed and corresponding video encoder instances are initiated. The preprocessed video source stream is split into video data components, which are assigned to a corresponding encoder instance. Encoding operations are performed by each video encoder instance to generate video output components. The video output components are then assembled in a predetermined sequence to generate an encoded video output stream. Concurrently, the audio source stream is encoded with an audio encoder to generate an encoded audio output stream. The encoded video and audio output streams are combined to generate a combined encoded output stream, which is provided as combined video and audio output.Type: GrantFiled: November 6, 2008Date of Patent: August 21, 2012Assignee: Advanced Micro Devices, Inc.Inventor: Hans W.

Patent number: 8225093Abstract: Providing for secure and efficient communication for mobile applications executed in a mobile operating environment is described herein. As an example, a primary mobile application can initiate a handshake that includes a unique identifier of the primary application and a random number for signing and/or certifying responsive requests. A recipient application can reference the unique identifier with a list of certified primary applications to verify the primary application. If verified, the recipient responds with the random number and a second random number that can sign and/or certify data requests sent by the primary application. According to some embodiments, random numbers can be hashed and/or truncated to provide low power encryption for such numbers. Further, round-trip policies can be enforced to provide reliable transmission of data. Accordingly, reliable, secure and low power synchronous communication can be conducted in a mobile environment.Type: GrantFiled: November 29, 2007Date of Patent: July 17, 2012Assignee: QUALCOMM IncorporatedInventors: Kenny Fok, Jihyun Hwang, Eric Chi Chung Yip, Mikhail A.

Patent number: 8223836Abstract: A constant-quality rate control system and algorithm for multiple encoders with a single video source are disclosed. The system comprises a base encoder, a region of interest (ROI) detector, and at least one ROI encoder. The base encoder encodes a base video sequence which is a down-sampled version of a video sequence and sends the base video sequence to a multiplexer. The ROI detector extracts an ROI video sequence from the original video sequence. The ROI encoder encodes the ROI video sequence and sends it to the multiplexer. The ROI encoder uses information obtained during encoding of the base video sequence to improve the encoding of the ROI video sequence. The information of the base video sequence are used to better control the bit-rate and the quality of the ROI video sequence.Type: GrantFiled: August 17, 2007Date of Patent: July 17, 2012Assignee: National Taiwan UniversityInventors: Ping-Hao Wu, Homer H.

Patent number: 8223846Abstract: A spatial error concealment (SEC) method for concealing a spatial image error of an encoded image frame caused by a damaged macroblock (MB) is provided. The SEC method selects a proper SEC algorithm by adaptively classifying a plurality of correct MBs adjacent to the damaged MB, so as to execute interpolation pixel compensation or matching block copying, thus obtaining image data of the damaged MB. In such a way, the damaged MB is processed to apply the least affection to the entire image frame. The SEC algorithm is selected from bilinear interpolation (BI) method, directional interpolation (DI) method, multi-directional interpolation (MDI) method, and best neighborhood matching (BNM) method. The SEC method further includes a fast determination calculation, which utilizes image directional data related to the damaged MB in coding data of the original frame to execute a direct SEC process, for saving time on determination calculation, thus accelerating the processing speed.Type: GrantFiled: October 31, 2008Date of Patent: July 17, 2012Assignee: National Taiwan UniversityInventors: Shih-Chia Huang, Sy-Yen Kuo

Patent number: 8179964Abstract: Transcoder chip having a buffer for temporarily storing decoded macroblocks and compressed domain parameters. A video decoding module of the transcoding chip decodes and stores the decoded macroblocks in the buffer in a first sequence. The video encoding module then reads the data from the buffer in a second sequence different from the first sequence to encode the macroblocks in a different format. The buffer can also be used for deblocking the macroblocks and for filtering motion vectors. By using the buffer, data traffic between the transcoding chip and external memory is reduced, increasing the speed for transcoding a video sequence from one format to another.Type: GrantFiled: September 7, 2007Date of Patent: May 15, 2012Assignee: Zenverge, Inc.Inventors: Anthony D.

Patent number: 8166550Abstract: Systems and methods for an anti-virus detection module that can detect known undesired computer files in damaged archives that may be encrypted, compressed and/or password-protected are provided. According to one embodiment, a damaged or incomplete RAR, CAB or ZIP archive is received. Without decrypting or decompressing the contents, an anti-virus detection module identifies the archive as a RAR, CAB or ZIP archive by assuming each of multiple possible archive types in turn and searching all of or certain parts of the archive for content consistent with a current archive type. Based on the identified type, for each contained file, descriptive information is extracted from corresponding local file headers and a threat evaluation is performed by comparing the descriptive information to signatures of known malicious or undesired files. If the threat evaluation concludes a particular contained file is a threat, then appropriate defensive actions are taken in relation to the archive.Type: GrantFiled: October 6, 2010Date of Patent: April 24, 2012Assignee: Fortinet, Inc.Inventors: Steven Michael Fossen, Alexander Douglas MacDonald
