A method including: populating an encoding ladder with a subset of bitrate-resolution pairs, from a set of bitrate-resolution pairs, based on a distribution of audience bandwidths; receiving a first request for a first playback segment, at a first bitrate-resolution pair in a encoding ladder, in the video from a first device; in response to determining an absence of video segments, at the first bitrate-resolution pair and corresponding to the segment, in a first rendition cache: identifying a first set of mezzanine segments, in the video, corresponding to the first playback segment; assigning the first set of mezzanine segments to a set of workers for transcoding into a first set of video segments according to the first bitrate-resolution pair; storing the first set of video segments in the first rendition cache; and based on the first request, releasing the first set of video segments to the first device.

One aspect of the present invention discloses a network system capable of transmitting and processing audio video (“A/V”) data with enhanced quality of service (“QoS”). The network system includes a transmitter, a transmission channel, an adjustable decoder buffer, and a decoder. The transmitter contains an encoder able to encode A/V data in accordance with encoding bit rate recommendation from SQoS and packets loss notifications. The transmission channel, in one example, transmits A/V data from the transmitter or the receiver. The adjustable decoder buffer, in one aspect, is able to change its storage capacity or buffering size in response to the adaptive latency estimate. Upon fetching at least a portion of the A/V data from the adjustable decoder buffer, SQoS updates the adaptive latency estimate based on the quality of the decoded A/V data.

Systems, methods, devices and non-transitory, computer-readable storage mediums are disclosed for a wearable multimedia device and cloud computing platform with an application ecosystem for processing multimedia data captured by the wearable multimedia device. In an embodiment, a method comprises: receiving, by one or more processors of a cloud computing platform, context data from a wearable multimedia device, the wearable multimedia device including at least one data capture device for capturing the context data; creating a data processing pipeline with one or more applications based on one or more characteristics of the context data and a user request; processing the context data through the data processing pipeline; and sending output of the data processing pipeline to the wearable multimedia device or other device for presentation of the output.

A method comprising: receiving a plurality of duplicates of a serial bit stream, wherein said serial bit stream comprises a sequence of data packets; continuously dividing each of said duplicates of said serial bit stream based on sequential time windows; with respect to each of said time windows, aligning said data packets associated with each of said duplicates of said serial bit stream, received within said time window, based, at least in part, on data packet similarity; and recreating in real time said serial bit stream by selecting at least one of said aligned data packets as representing a next data packet in said sequence of data packets.

A method and apparatus include including, in a moving pictures experts group (MPEG) dynamic adaptive streaming over hypertext transfer protocol (DASH) media presentation description (MPD) file, an initialization presentation element that identifies an initialization presentation and one or more initialization groups included in the initialization presentation. An initialization group element that identifies an initialization group and one or more initialization sets included in the initialization group is included in the MPD file. An initialization set element that identifies an initialization set is included in the MPD file. The MPD file is transmitted to a client device.

A content delivery system adapted to provide access to local content is provided. In one embodiment, the system includes a stream director server and an encoder. The stream director server is adapted to receive a request for local content from a client, determine an identifier corresponding to the local content, and provide a redirect to the client based on the identifier. The encoder is adapted to receive a redirected request from the client and provide the local content to the client for presentation. A method of providing access to local content is also provided. The method includes receiving a request for local content from a client at a server; parsing client identifying data and content identifying data from the request; authenticating the request based at least in part on the client identifying data; and providing a redirect to the client for the requested content.

A system for providing networked access to media signals, the system comprising at least one virtual media card configured to interface with at least one application that produces and/or consumes media signals, and/or at least one media interface configured to interface with at least one physical media card that produces and/or consumes media signals. The system may also comprise a network interface configured to enable the system to exchange media signals with other devices on a common network, and a reference clock configured to provide a common clock signal to the at least one virtual media card, the at least one media interface, and the common network. An advertisement and discovery module configured to identify when the at least one application is started and/or stopped and when the at least one media card is attached and/or detached from the system may also be provided. The advertisement and discovery module is configured to: (i) make I/O channels of the at least one media card available to the system and the common network, and (ii) make I/O channels of the at least one application available to the system and the common network.

There is provided a method for streaming a multichannel audio signal comprising a first channel (L) and a second channel (R) from an audio source device to a binaural hearing system comprising a first hearing device worn at first ear of a user and a second hearing device worn at a second ear of the user.

Provided is an image transmission method. Left-eye image data and right-eye image data corresponding to a same original image frame in a target video are divided into sub-images on the image processing device side, multiple sets of image data in one-to-one correspondence with the sub-images are generated, and transmitted to the image display device through transmission threads. Each of the multiple sets of image data includes a sub-image, and first and second sequence numbers that correspond to the sub-image. Left-eye image data and right-eye image data corresponding to a same original image frame are obtained by combining sub-images in the multiple sets of image data, by the image display device, based on first and second sequence numbers in the multiple sets of image data. Finally, a left-eye image corresponding to the left-eye image data and a right-eye image corresponding to the right-eye image data are played.

There are provided an information processing apparatus, an information processing method, and a program. The information processing apparatus includes a generating unit configured to generate a content file including object selection information for selecting object audio data in accordance with a display state of an image, in which the generating unit stores the object selection information in a metadata file included in the content file.
