11582182 · 2023-02-14 · ·

One or more embodiments of the disclosure provide systems and methods for providing media presentations to users of a media presentation system. A media presentation generally includes a plurality of media segments provided by multiple users of the media presentation system. In one or more embodiments, a user of the media presentation system may share a media presentation with a co-user. The media presentation system can provide a number of features to assist a user in sharing, filtering, and accessing media presentations.

Password-based authorization for audio rendering

A method and device for processing one or more audio streams based on password-based privacy restrictions is described. A device may be configured to receive unrestricted audio streams of the one or more audio streams based on privacy restrictions associated with a password, wherein the one or more audio streams are from audio elements represented in an acoustic environment that comprises one or more sub-acoustic spaces, each of the one or more audio streams representative of a respective soundfield, and generate the respective soundfields of the unrestricted audio streams.

Computer-based systems configured to adjust data capacity in a data stream generated from multiple data producer applications and methods of use thereof

A method includes receiving from a transmitting data interface, a data stream mapping of a data input into data shards for transmission in a data stream over a data stream communication channel. Data capacity for a data producing software application from a plurality of data producing software applications is adjusted by increasing or decreasing a number of data shards in the data stream assigned to the data producing software application. An updated data stream mapping of the data input into the plurality of data shards is generated by updating a start hash key and an end hash key in a range for each of the data shards assigned to the data producing software application. The updated data stream mapping is sent to the transmitting data interface for adjusting the data capacity in the data stream transmitted over the data stream communication channel of the data producing software application.

DYNAMIC REDUNDANCY

A device implementing dynamic redundancy may include at least one processor configured to receive, from another device, packet reception data corresponding to video data previously provided for transmission from the device to the other device and determine, based at least in part on the packet reception data, an amount of redundancy to apply to video data provided for transmission to the other device. The at least one processor may be further configured to determine, based at least in part on the amount of redundancy, an encoding scheme for applying the redundancy to the video data. The at least one processor may be further configured to apply the amount of redundancy to the video data based at least in part on the encoding scheme to generate redundant data items and provide the video data and the redundant data items for transmission to the other device.

Program Mode Transition

A computing system is configured to execute a computer program on a server and to provide a video stream of the program output to a geographically remote client over a communication network. The computing system is further configured to provide executable content of the computer program to the client over the communication network in parallel with the video stream. When a sufficient amount of the executable content has been provided to the client execution of the computer program is transitioned from the server to the client. The transition optionally includes communicating a state of the computer program from the server to the client. The executable content can be provided to the client in an order that is determined based on the state of the computer program. Those parts of the executable content deemed most likely to be necessary to support game play on the client are given priority.

Communication system, network-side apparatus, transmission function changing method and program

A communication system includes a network-side apparatus and a user-side apparatus. The network-side apparatus includes a transmission function unit configured to perform processing of a transmission function on data received from the user-side apparatus, a quality calculation unit configured to calculate a quality of media data which is transmitted from the user-side apparatus and on which the processing is performed by the transmission function unit; and a transmission function changing unit configured to change the transmission function performed by the transmission function unit in a range in which the calculated quality satisfies a quality required by an application.

Communication terminal, communication system, communication method, and display method

A communication terminal includes a memory and circuitry. The memory stores, for each image type information indicating a type of image data, sizes of a plurality of display areas, each display area being a divided area divided from an entire area displayable by a display, in association with required resolutions of image data to be displayed in the corresponding display areas. The circuitry receives, from a communication management system, specific image type information indicating a type of specific image data transmitted from other communication terminal. The circuitry transmits, to the communication management system, specific required resolution, which is a resolution stored in the memory for the specific image type information in association with the size of one of the display areas in which the specific image data is to be displayed.

Resource segmentation to improve delivery performance

A flexible approach to segmenting a resource (e.g., a media resource, such as a media segment, or other resource, such as a resource normally fetched or pushed using general file transfer protocols like HTTP) into a plurality of fragments. By employing such an approach, the delay until the resource can be utilized at the client side is reduced. Certain embodiments are provided which apply the flexible segmentation approach to ISOBMFF media segments for video streaming, such as would be used with Live DASH streaming.

Synchronizing playback by media playback devices

Example systems, apparatus, and methods receive audio information including a plurality of frames from a source device, wherein each frame of the plurality of frames includes one or more audio samples and a time stamp indicating when to play the one or more audio samples of the respective frame. In an example, the time stamp is updated for each of the plurality of frames using a time differential value determined between clock information received from the source device and clock information associated with the device. The updated time stamp is stored for each of the plurality of frames, and the audio information is output based on the plurality of frames and associated updated time stamps. A number of samples per frame to be output is adjusted based on a comparison between the updated time stamp for the frame and a predicted time value for play back of the frame.
