Patent number: 9712847Abstract: An invention is disclosed for encoding and decoding data in a 4:4:4 subsampling scheme, using an encoder/decoder that is not configured to encode or decode data in 4:4:4. In embodiments, an encoder planararizes an input frame into three component frames in a 4:0:0 scheme. The encoder then encodes each component frame in the 4:0:0 scheme, and aggregates the encoded component frames into a bit stream. A decoder receives such a bit stream, and decodes it with a component not configured to decode data in 4:4:4. The decoder decodes the bit stream to produce a representation of the three component frames in 4:0:0, then aggregates the three component frames into a representation of the original frame in 4:4:4.Type: GrantFiled: September 20, 2011Date of Patent: July 18, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Krishna Mohan Malladi, B.

Patent number: 9167020Abstract: An invention is disclosed for conducting a remote presentation session with a client that uses a web browser to conduct the session. In embodiments, a proxy server exists between the remote presentation server and the client. The proxy server establishes a HTTP session with the client and a remote presentation session with the client. The server generates graphics encoded with a remote presentation protocol and sends them to the proxy, which re-encodes them as video and sends them to the client for display in the web browser. The client captures user input at the web browser and sends it to the proxy, which encodes it with the remote presentation protocol and sends it to the server to be processed.Type: GrantFiled: June 10, 2011Date of Patent: October 20, 2015Assignee: Microsoft Technology Licensing, LLCInventors: Nadim Y. Abdo, B. Anil Kumar, Wilhelm R. Schmieder, Sridhar Sankuratri, Krishna Mohan Malladi, Asael Dror, Joy Chik, Nelamangal Krishnaswamy Srinivas, Tad Brockway

Patent number: 8958474Abstract: A system and method for effectively encoding and decoding a wide-area network based remote presentation scheme makes use of a scalable video codec (SVC) to encode multiple screen data. A RGB frame of each screen is converted into YUV444 which is subsequently converted into two YUV420 frames. The V frame of the YUV444 is divided into four sub-frames. Two of those sub-frames are combined with the Y frame to create the first YUV420 frame. A second YUV420 frame is created by combining the remaining two V sub-frames with the U frame. The two YUV420 frames are encoded separately by using SVC or together by using Multi-View Codec. An SVC decoder receives and decodes two such YUV420 frames. Those decoded YUV420 frames are then used to obtain the YUV444 frame which is subsequently converted in to RGB frame to display the image on a screen.Type: GrantFiled: March 15, 2012Date of Patent: February 17, 2015Assignee: Virtualinx, Inc.Inventor: Krishna Mohan Malladi

Publication number: 20120075346Abstract: Exemplary techniques for performing motion compensation in the discrete wavelet transform domain are described. In an exemplary embodiment, a server can perform motion compensation in the discrete wavelet transform domain for an image and send at least one motion vector and at least one delta array to a client. The client can use the at least one motion vector and the at least one delta array to compose the image. In addition to the foregoing, other aspects are described in the detailed description, claims, and figures.Type: ApplicationFiled: September 29, 2010Publication date: March 29, 2012Applicant: Microsoft CorporationInventors: Krishna Mohan Malladi, B.

Patent number: 7720300Abstract: A system and method for effectively performing an adaptive quantization procedure includes an energy calculator that initially determines energy values for subbands of input data. A quantizer receives initial quantization parameters that each correspond to a different respective one of the subbands. The quantizer calculates adaptive quantization parameters from the initial quantization parameters by utilizing corresponding ones of the energy values. The quantizer then utilizes the adaptive quantization parameters to generate quantized coefficients for the subbands during the adaptive quantization procedure.Type: GrantFiled: December 5, 2006Date of Patent: May 18, 2010Assignee: Calister TechnologiesInventors: Krishna Mohan Malladi, B.

Patent number: 7460725Abstract: A system and method for effectively encoding and decoding electronic information includes an encoding system with a tiling module that initially divides source image data into data tiles. A frame differencing module then outputs only altered data tiles to various processing modules that convert the altered data tiles into corresponding tile components. A quantizer performs a compression procedure upon the tile components to generate compressed data according to an adjustable quantization parameter. An adaptive entropy selector then selects one of a plurality of available entropy encoders to most effectively perform an entropy encoding procedure to thereby produce encoded data. The entropy encoder may also utilize a feedback loop to adjust the quantization parameter in light of current transmission bandwidth characteristics.Type: GrantFiled: November 9, 2006Date of Patent: December 2, 2008Assignee: Calista Technologies, Inc.Inventors: Krishna Mohan Malladi, B.
