Steve Bramwell - San Diego CA, US
Jason Braness - San Diego CA, US
Abhishek Shivadas - San Diego CA, US
Assignee:
Rovi Technologies Corporation - Santa Clara CA
International Classification:
H04N 9/80
H04N 5/92
US Classification:
386241, 386244, 386E09011, 386E05009
Abstract:
Systems and methods for adaptive bitrate streaming of media including subtitles utilizing Hypertext Transfer Protocol (HTTP) in accordance with embodiments of the invention are disclosed. One embodiment of the invention includes requesting and buffering portions of video from at least one of the alternative streams using a playback device, requesting information indicative of a font utilized by a font-rendering engine to render text from a selected subtitle stream, downloading at least one font file when the font is not present on the playback device, requesting and buffering at least a portion of the selected subtitle stream, decoding the buffered portions of video using a decoder on the playback device, rendering the portions of the subtitle stream corresponding to the buffered portion of video using a font-rendering engine configured by the at least one downloaded font file, and performing synchronized playback of the decoded video and rendered subtitles using the playback device.

Abstract:
Systems and methods for the selection of resolutions for seamless resolution switching of multimedia content in accordance with embodiments of the invention are disclosed. In one embodiment of the invention, a source encoder includes a processor configured by a source encoder application to receive multimedia content, where the multimedia content comprises video data having a primary resolution and a primary sample aspect ratio and encode the video data as a set of alternative streams, where a plurality of the streams in the set of alternative streams have different maximum bitrates and resolutions, the resolution of each of the plurality of streams comprises a width and height that are both an integer number of pixels, and both the width and height of each of the plurality of streams is a common fraction of the width and height of the corresponding primary resolution.

US Patent:
20130339855, Dec 19, 2013
Filed:
Jun 13, 2012
Appl. No.:
13/495757
Inventors:
Abhishek Shivadas - San Diego CA, US
Kourosh Soroushian - San Diego CA, US
Assignee:
DIVX, LLC - Santa Clara CA
International Classification:
G06F 3/01
G06F 15/16
US Classification:
715720
Abstract:
Systems and methods for adaptive streaming systems configured to generate interactive video timelines in accordance with embodiments of the invention are disclosed. In one embodiment of the invention, a method for selecting video to stream and playback using an interactive video timeline includes selecting a plurality of frames of video from a first stream of video data using a network client, displaying the plurality of frames of video in an interactive video timeline using the network client, selecting a playback frame of video data from the plurality of frames of video in the interactive video timeline using the network client, receiving a second stream of video data beginning from the playback frame of video data using the network client, and playing the second stream of video data using the network client.

US Patent:
20140068096, Mar 6, 2014
Filed:
Sep 28, 2012
Appl. No.:
13/631017
Inventors:
Abhishek Shivadas - San Diego CA, US
Kourosh Soroushian - San Diego CA, US
Assignee:
DIVX, LLC - Santa Clara CA
International Classification:
G06F 15/16
US Classification:
709231
Abstract:
System and methods for selecting one of the alternative streams of encoded media from a group of alternative streams of encoded media for use during start-up of playback of the encoded media in accordance with embodiments of this invention are disclosed. The systems and methods begin by determining an estimated stability period for a current bandwidth of a communicative connection between the playback device and a remote system providing the alternative streams of encoded. A test process is then performed on the streams of encoded media to select one of streams of encoded media that provides portions of said encoded media such that an underflow condition does not occur during the estimated stability period. The streaming of encoded media is then commenced by requesting the portions of encoded media be transmitted from the remote server using the selected stream.
