Appl. No.:

13/041362

Assignee:

Dolby Laboratories Licensing Corporation - San Francisco CA

International Classification:

H04N 9/80

US Classification:

386248

Abstract:

Techniques for providing application tracks in a media data container are described. An application descriptor may be extracted from a coded bitstream. The coded bitstream comprises media data to be played by a media presentation system. The application descriptor identifies an application archive (i) that is retrievable by the media presentation system from one or more sources and (ii) that is required by the media presentation system at a set media time associated with the media data. While playing the media data, the media presentation system causes retrieving all of the application archive from the one or more sources before the set media time.

H04B 1/66
H04N 11/02

US Classification:

375240120, 375240240

Abstract:

A motion detection system can detect motion at a macroblock level of granularity and take an action based on the detection of motion or an event in a specified region of interest. The system comprises an ASIC capable of detecting an event in a macroblock of a frame of a video sequence, and an eventing engine for, responsive to the detection of the event by the ASIC, performing an action. Such a system can be configured by a user who provides an input specifying a region of interest on which motion detection should be performed by the motion detection system and a threshold value for determining whether or not motion has occurred in the region of interest.

H04N 11/02

US Classification:

348 43, 3483841, 348E13001, 348E11006

Abstract:

Techniques for multi-view video format control are provided. In some embodiments, a display video format supported by a display panel is determined. A video format code is extracted from a coded bitstream in which a plurality of images is encoded in two or more source video formats. The video format code identifies a source video format in which a set of images in the plurality of images is encoded. A video format filter is selected to modify the set of images encoded in the source video format to generate another set of images encoded in the display video format. The other set of images encoded in the display video format is sent to the display panel.

International Classification:

G06F 15/16

US Classification:

709203

Abstract:

A DNS component functions privately in relation to a group of client devices, each associated with a unique URL maintained with the DNS component that privately identifies the devices within the group. The URL identifies a hierarchy of private domains enforced within the group which, at least implicitly, represents private relationships therein between the devices. Network rules are applied over the group based on the private relationships or the private domains. The devices are securely authenticated within the group. A content sharing service component allows devices within the group to access information content associated with other group devices based, at least partially, on the devices' URLs. A private IP based internet allows group devices secure access to the group from external networks and free access to other devices within the group.

International Classification:

H04N 13/00

US Classification:

348 43, 348E1306

Abstract:

Techniques for converting 3D images using alpha maps are described. A left-view image and a right-view image may be determined from media data received by a 3D display system. An alpha map specifying a plurality of operations for a plurality of locations that correspond to the first plurality of locations in the images may also be determined. The plurality of operations specified in the alpha map may be applied by the 3D display system to process the left-view and right-view images, and to generate, based on the left-view and right-view images, a third image in an appropriate 3D format.

International Classification:

G06F 15/16

US Classification:

709219

Abstract:

A unified media content directory may be created for multiple computing devices that store media content. These computing devices may be in the same network domain or span across different network domains. These computing devices may provide their media content through the unified media content directory based in part on standard technologies. A client that has a limited security permission may be able to access the unified media content directory and the media content identified in the unified media content directory in an intuitive, consistent manner, no matter where the client may be located, assuming the client has adequate digital rights for the media content the client. Additionally, load conditions of the media content servers may be monitored. A load balancing algorithm and high availability for accessing a piece of media content may be provided, if the media content can be accessed through more than one media content server.

Abstract:

Modifying images for a 3-dimensional display mode includes receiving a third image encoded for a 3-dimensional display mode, receiving a first image not encoded for the 3-dimensional display mode, modifying the first image to generate a second image encoded for the 3-dimensional display mode, and displaying the third image and the second image in the 3-dimensional display mode.
