Patent number: 8332657Abstract: A method for providing local security of audio and video content during transmission and storage within digital home networks. Scrambled content may be recorded in all conditions, however, only authorized copies are processed for descrambling and viewing. Content is protected within a network by rebundling the keys required for descrambling, e.g., the TDES keys, into a new ECM (LECM), which is protected by a local public key.Type: GrantFiled: March 15, 2000Date of Patent: December 11, 2012Assignee: Thomson LicensingInventors: Ahmet Mursit Eskicioglu, David Emery Virag, David Jay Duffield, Michael Scott Deiss, Billy Wesley Beyers, Jr.

Patent number: 7800690Abstract: An adaptive digital image processor precedes an MPEG2 encoder. The processor receives a high definition video signal intended for broadcast or storage, and adaptively low-pass filters the signal. The signal is subjected to low-pass two-dimensional filtering to eliminate encoding artifacts and related noise. The video signal is then horizontally down-sampled to create a lower resolution hybrid signal. A receiver decodes and decompresses the hybrid signal. The hybrid signal is upsampled to its original resolution using existing hardware and software with a software modification.Type: GrantFiled: December 15, 2004Date of Patent: September 21, 2010Assignee: Thomson LicensingInventors: Haoping Yu, David Lowell McNeely, Billy Wesley Beyers, Jr.

Patent number: 7664268Abstract: A method for providing conditional access (i.e., managing access) to a received scrambled audio/visual (A/V) signal from a variety of sources by utilizing secret sharing for key recovery. Secret sharing eliminates the necessity to protect and transfer the complete descrambling keys between devices, because a portion of the key is stored in the device or a smart card coupled thereto.Type: GrantFiled: December 9, 1998Date of Patent: February 16, 2010Assignee: Thomson LicensingInventors: Ahmet Mursit Eskicioglu, Mehmet Kemal Ozkan, Billy Wesley Beyers, Jr.

Patent number: 7020205Abstract: In encoding and decoding video signals, a progressive video bitstream is received which has reference frames and non-reference frames, each having an initial temporal reference in accordance with an initial frame sequence structure. The temporal references of the only the reference frames are remapped, by ignoring the non-reference frames. The reference frames are packetized with a base packet-identifier (PID) and the non-reference frames with an enhancement PID, to provide base and enhancement transport bitstreams, respectively.Type: GrantFiled: July 12, 2000Date of Patent: March 28, 2006Assignee: Thomson LicensingInventors: Billy Wesley Beyers, Wai-Man Lam

Patent number: 6788710Abstract: A digital device, such as a digital VTR, receives and records an MPEG compatible datastream. On play back, the DVTR inserts packetized auxiliary information, such as on-screen display information, into the transport datastream for transmission to another digital device, such as a television receiver. Time stamps in the MPEG compatible datastream are unaffected by the insertion of the auxiliary information. The DVTR VSB modulates the datastream to provide sufficient bandwidth for the auxiliary information in the datastream.Type: GrantFiled: November 6, 1998Date of Patent: September 7, 2004Assignee: Thomson Licensing S.A.Inventors: Paul Gothard Knutson, Billy Wesley Beyers, Jr., Kumar Ramaswamy, Thomas Anthony Stahl

Patent number: 6621934Abstract: An image processor produces a DPCM prediction error to be quantized. If the prediction error value is positive, the value passes unchanged to a quantizer. If the prediction error value is negative, a bias value is added to the prediction error value to produce a positive number within the operating limits of the quantizer. Biased prediction error values are quantized. Because all values received by the quantizer are positive and within the current quantizer limits, the quantization table used by the quantizer need not include quantization values for negative prediction error values. This reduces the scope of prediction error values by a factor of two, doubling quantization resolution.Type: GrantFiled: August 12, 1997Date of Patent: September 16, 2003Assignee: Thomson Licensing S.A.Inventors: Haoping Yu, Barth Alan Canfield, Billy Wesley Beyers, Jr., Wai-man Lam

Patent number: 6529551Abstract: An MPEG coded and compressed video signal is received and decompressed for display. Prior to storing frames required for motion compensation in memory, pixel blocks are recompressed into DPCM prediction error values to reduce bandwidth and frame memory requirements. Fixed length quantization and dequantization tables (FIG. 2) have N levels (e.g., 15 levels), and each level has an associated output symbol of predominantly M bits (e.g., 4 bits), except that at least one of said N levels (e.g., level 7) is defined by a unique short symbol having less than M bits (e.g., 3 bits), and input data for that level is received at a desired rate. Each time a short symbol is used to represent a data value, bandwidth and memory are reduced and/or preserved for other uses, for example, inserting overhead data into a fixed-size data stream. For large sequences of data, such as exists for video data for example, the reduction in memory and bandwidth is significant.Type: GrantFiled: August 12, 1997Date of Patent: March 4, 2003Assignee: Thomson Licensing S.A.Inventors: Haoping Yu, Barth Alan Canfield, Billy Wesley Beyers, Jr., Wai-man Lam

Patent number: 6256347Abstract: A memory efficient image processor receives DPCM prediction error values from decompressed MPEG coded digital video signals in the form of pixel blocks containing luminance and chrominance data in a 4:2:2 or 4:2:0 format and recompresses the pixel blocks to a predetermined resolution. Luminance and chrominance data are processed with different compression laws during recompression. Luminance data are recompressed to an average of six bits per pixel, and only a reference pixel and one other pixel are processed separately from all other luminance pixels in a block. Chrominance data are recompressed to an average of four bits per pixel. Each pixel block is stored with overhead information facilitating efficient and accurate reconstruction.Type: GrantFiled: August 12, 1997Date of Patent: July 3, 2001Assignee: Thomson Licensing S.A.Inventors: Haoping Yu, Barth Alan Canfield, Billy Wesley Beyers, Jr., Wai-man Lam

Patent number: 6167086Abstract: In an MPEG compatible image signal processor an MPEG data stream is decoded, decompressed and recompressed before blocks of image pixel values are stored in memory. The recompression system evaluates block data to determine the range and minimum pixel values for a given image block of pixels values. These values are encoded, and the encoded representations are stored in a parameter field with the quantized data block to facilitate data reconstruction. Encoding occurs by fitting the actual range and minimum values to a predetermined set of values. Each selected predetermined value is then encoded as a three-bit index in the parameter field. Storing the encoded values with the quantized data facilitates reconstruction with minimal error. Also, encoding the values preserves memory for the quantized data.Type: GrantFiled: August 12, 1997Date of Patent: December 26, 2000Assignee: Thomson Licensing S.A.Inventors: Haoping Yu, Barth Alan Canfield, Billy Wesley Beyers, Jr., Wai-man Lam

Patent number: 6081300Abstract: An apparatus and concomitant method for constructing a valid OSD message bitstream from a plurality of stored character bitstreams. Each character of the OSD font set is initially scaled into a fixed block size, e.g., a block size of 16.times.16 pixels. Each character is then encoded into a "character bitstream" using the intra macroblock coding syntax. The character bitstream is stored within a storage medium. When a frame of OSD messages needs to be encoded, the character bitstreams are read from the storage medium and cascaded to form a valid OSD message bitstream which represents the frame of OSD messages.Type: GrantFiled: November 24, 1997Date of Patent: June 27, 2000Assignee: Thomson Consumer Electronics, Inc.Inventors: Billy Wesley Beyers, Jr., Wai-Man Lam

The ring bus transmits data in successive bus cycles, each bus cycle containing a plurality of bus words. One of the bus words in the bus cycle is a bus cycle synchronization word and the remainder of which are data words. The plurality of data words are allocated to a plurality of data channels.Type: GrantFiled: November 17, 1997Date of Patent: June 6, 2000Assignee: Thomson Consumer Electronics, Inc.Inventor: Billy Wesley Beyers, Jr.
