Publication number: 20110157264Abstract: A communication system is described that allows co-located viewers to simultaneously consume different media content, such as different video content, via the same display screen, wherein video content delivered to at least one co-located viewer is not visible to the other co-located viewer(s). The communication system comprises an infrastructure that includes multiple pathways for delivering media content from one or more media sources to the eyes of each of the co-located viewers, wherein each pathway passes through the pixels of a pixel array included in the shared display screen. The pathways also include distributed or non-distributed processing circuitry that manages certain resources that are shared among the multiple pathways, wherein such shared resources may include shared display resources (e.g., pixels of the pixel array and light generated thereby) and shared data communication resources (e.g., bandwidth on data communication links and processing resources of nodes located on such links).Type: ApplicationFiled: December 30, 2010Publication date: June 30, 2011Applicant: BROADCOM CORPORATIONInventors: Nambirajan Seshadri, Jeyhan Karaoguz, James D.

Publication number: 20110157315Abstract: Techniques are described herein for interpolating three-dimensional video content. Three-dimensional video content is video content that includes portions representing respective frame sequences that provide respective perspective views of a given subject matter over the same period of time. For example, the three-dimensional video content may be analyzed to identify one or more interpolation opportunities. If an interpolation opportunity is identified, frame data that is associated with the interpolation opportunity may be replaced with an interpolation marker. In another example, a frame that is not directly represented by data in the three-dimensional video content may be identified. For instance, the frame may be represented by an interpolation marker or corrupted data. The interpolation marker or corrupted data may be replaced with an interpolated representation of the frame.Type: ApplicationFiled: December 30, 2010Publication date: June 30, 2011Applicant: BROADCOM CORPORATIONInventors: James D.

Publication number: 20110157336Abstract: A display system is provided that enables three-dimensional images to be displayed. The display system includes an elastic light manipulator positioned proximate an image generator. The image generator includes a pixel array. The elastic light manipulator includes an elastic material and is mounted in a manner that allows for automated stretching thereof. For instance, the elastic light manipulator may be an elastic lenticular lens, an elastic parallax barrier, etc. Because the elastic light manipulator can be stretched, optical properties of the elastic light manipulator can be dynamically modified, thereby changing the manner in which light emanating from the pixel array is delivered to the eyes of viewer(s). This allows for adaptive accommodation of, for example, a changing viewer sweet spot. The elastic light manipulator may be automatically rolled up or otherwise automatically removed from in front of the image generator in order to facilitate switching between 2D and 3D views.Type: ApplicationFiled: May 5, 2010Publication date: June 30, 2011Applicant: BROADCOM CORPORATIONInventors: James D.

Patent number: 7969353Abstract: A method, apparatus and system for time management in a position-location system is described. The method may include (i) obtaining, at a global-navigation-satellite-system receiver while being served by a first node of a wireless network a first time base, a relative-time difference, and a third time base; and forming a time relation as a function of the first time base, relative-time difference (“RTD”) and third time base. The first time base is associated with the first node, and may be, for example, a time base associated with an air interface for communicating with the first node. The RTD may be a difference between the first time base and a second time base associated with a second node of the wireless network. The third time base is associated with a constellation of satellites, and may be, for example, an absolute time associated with the constellation of satellites.

Patent number: 7971108Abstract: Systems and methods are described for managing bit errors present in a series of encoded bits representative of a portion of an audio signal, wherein the series of encoded bits is received over a communication link in an audio communications system. At least one characteristic of a portion of a received modulated carrier signal that is demodulated to produce the series of encoded bits is determined. A number of bit errors present in the series of encoded bits is then determined based on the at least one characteristic. Based on the estimated number of bit errors, one of a plurality of methods for producing a series of digital audio samples representative of the portion of the audio signal is selectively performed. The series of digital audio samples produced by the selected method is then converted into a form suitable for playback to a user.Type: GrantFiled: July 21, 2009Date of Patent: June 28, 2011Assignee: Broadcom CorporationInventors: Robert W.

Patent number: 7970262Abstract: A system, method, and apparatus for decoding and displaying images utilizing two processors and two memory units. The decode process receives images which are encoded according to a predetermined standard. Included with the encoded images are parameters which facilitate the decode and display processes. The decode process decodes the encoded images and the encoded parameters and stores each image in a separate image buffer, and each set of associated parameters in a buffer descriptor structure associated with the image buffer. The decode process is carried on by the first processor. The display process utilizes the parameters associated with the image to determine the appropriate display order for each image, and then display the image accordingly on a display device, based on the associated parameters. The first processor carries on the display of the image on the display device. The second processor determines the display order for the images. The second processor and the second memory can be off-chip.Type: GrantFiled: August 10, 2004Date of Patent: June 28, 2011Assignee: Broadcom CorporationInventors: Santosh Savekar, Moovaraivendren Subramanian

Patent number: 7970124Abstract: A system and method for provide a stable gain from an adaptive gain control device in a signal path. An echo canceller is also located in the signal path, and is used to provide performance information regarding losses in the signal. This performance information is fed to the automatic gain control device via a connection. The automatic gain control device thereafter uses the performance information to determine a maximum gain that might be provided based upon losses cause by echo conditions. The gain however is limited in order to provide for a stable system. The performance information includes a loss rate that includes a combination of the echo return loss and the echo return loss enhancement.Type: GrantFiled: January 9, 2007Date of Patent: June 28, 2011Assignee: Broadcom CorporationInventor: Wilfrid LeBlanc
