The server system receives, from a respective remote physical client device, a digest of a segment of video content received by the respective remote physical client device, the segment of video content including a plurality of frames of video content. In response to receiving the digest, the server system sends a playback command to the respective remote physical device to playback one or more of the plurality of frames of video content in the segment. The plurality of frames of video content in the segment have a frame rate. The server system determines a graphical processing unit (GPU) overlay instruction for overlaying content of a frame buffer with a respective portion of the segment of video content and sends, asynchronously from the frame rate of the plurality of frames of video content, the GPU overlay instruction to the respective remote physical client device.

Systems and methods of alternative networked application services

A server system hosts one or more virtual machines. The server system receives a first media stream that includes first content corresponding to a plurality of frames of video data and generates a first digest segment that corresponds to the first media stream, wherein the first digest segment includes a representation of the plurality of frames but does not include the video data. The server system stores the first digest segment in a cache at the server system; and receives a playback position of the first media stream at a first client device. The server system uses the playback position from the first client device and the first digest segment stored in the cache to perform processing to recreate a representation of the playback of the first media stream on the first client device.

The server system transmits, from a virtualized third-party application to a client device, an instruction to open a media resource from a content distribution network, the media resource comprising a plurality of video segments, each video segment of the plurality of video segments having video segment data and metadata. The server system receives, from the client device, first metadata for a first video segment of the plurality of video segments, without receiving first video segment data for the first video segment. The server system generates a recreated representation of the first video segment using the first metadata. The virtualized third-party application generates a transformed version of the recreated representation of the first video segment. The server system transmits, to the client device, an instruction to play the first video segment, wherein the instruction is based on the transformed version of the recreated representation of the first video segment.

Systems and methods of orchestrated networked application services

The server system hosts one or more virtual client devices executing one or more virtual applications, each virtual client device corresponding to a remote physical client device. The server system receives, from a first remote physical client device, a signal of a characteristic of media detected by a physical component of the first remote physical client device. The server system, in response to receiving the signal of the characteristic of the media, determines, based on the characteristic of the media, an instruction for adjusting the media detected by the physical component of the first remote physical client device and transmits, to the client device, the instruction for adjusting the media at the first remote physical client device.

Systems and methods of alternative networked application services for video-conferencing applications

A computing device receives a modified first image frame from a client device, wherein the client device stores the first image frame. The computing device generates a second image frame that corresponds to the modified first image frame with a watermark. The computing device transmits, to a third-party application executing at the computing device, the second image frame and generates an instruction for modifying the first image frame, the instruction based on an altered version of the second image frame that is identified by the watermark, the second image frame altered by the third-party application. The computing device transmits, to the client device, the instruction for modifying the first image frame.

Orchestrated control for displaying media

A server computing device hosts one or more virtual machines. A first virtual machine corresponding to a first client device receives a first media stream that includes first content corresponding to a plurality of frames of video data and generates a first digest segment that corresponds to the first media stream. The first digest segment includes a representation of the plurality of frames but does not include the video data. The first virtual machine stores the first digest segment in a cache at the server system. A second virtual machine corresponding to a second client device receives a playback position of the first media stream playing at the second client device and uses the playback position from the second client device and the first digest segment stored in the cache to perform processing to recreate a representation of the playback of the first media stream on the second client device.

A client device receives a first image frame from a server, stores the first image frame and generates a first modified image that corresponds to the first image frame. The client transmits, to a remote device, the generated first modified image. The remote device uses the first modified image to determine the instruction for displaying the second image frame. The client receives, from the remote device, an instruction for displaying a second image frame. In response to receiving the instruction, the client device displays, on a display communicatively coupled to the client device, the second image frame.

A server computing device receives, from a client device, a digest segment generated by the client device. The digest segment corresponds to a first media stream segment received by the client device, and the digest segment includes a representation of the first media stream segment. The server computing devices determines, using the digest segment, a playback command that corresponds to the first media stream segment and transmits, to the client device, the playback command.

A server system determines, for a group of user sessions assigned to a single modulator, that an aggregate bandwidth for a first frame time exceeds a specified budget for the modulator. The user sessions comprise data in a plurality of classes, each class having a respective priority. In response to a determination that the aggregate bandwidth exceeds a specified budget, the server system allocates a portion of the aggregate bandwidth, including allocating a first portion of the data for a first user session in the group of user sessions and allocating a second portion of the data for a second user session in the group of user sessions, where both the first portion and the second portion are allocated in accordance with the class priorities. The server system transmits the allocated portions of the data for the group of user sessions through the modulator during the first frame time.

Intelligent multiplexing using class-based, multi-dimensioned decision logic for managed networks

A server remote from a client device executes an HTML-based virtual client application. The server uses the HTML-based virtual client application to traverse a Document Object Model (DOM) tree to identify differences between a set of sequential images in sequential video frames of a sequence of video frames to render a rendered image corresponding to a video frame, the rendered image associated with HTML commands. The server uses the HTML-based virtual client application to generate an HTML wrapper for the rendered image that includes data encoded in accordance with the differences identified by traversing the DOM tree. The server sends the HTML wrapper to the client device to be processed by an HTML-based application on the client device to enable the image to be displayed at a display coupled to the client device.

Systems and methods for virtual set-top support of an HTML client

An electronic device sends a content stream, via an unmanaged network, toward a client device and monitors the capacity of the unmanaged network. The device determines whether an aggregate bandwidth of an upcoming portion of the content stream fits the capacity. The upcoming portion of the content stream includes video content and user-interface data. In response to a determination that the aggregate bandwidth of the upcoming portion of the content stream does not fit the capacity, when the user-interface data is not the result of a user interaction: the device prioritizes a frame rate of the video content over latency for the user-interface data, and in accordance with a determination that the aggregate bandwidth of the upcoming portion of the content stream does not fit the capacity, sends ahead one or more frames of the video content in the upcoming portion, and delays the user-interface data in the upcoming portion.

Class-based intelligent multiplexing over unmanaged networks

A method of adapting content-stream bandwidth includes generating a content stream for transmission over an unmanaged network with varying capacity and sending the content stream toward a client device. The method includes monitoring the capacity of the unmanaged network and determining whether an aggregate bandwidth of an upcoming portion of the content stream fits the capacity. The upcoming portion of the content stream includes video content and user-interface data. The method further includes, in response to a determination that the aggregate bandwidth of the upcoming portion of the content stream does not fit the capacity, prioritizing low latency for the user-interface data over maintaining a frame rate of the video content when the user-interface data is the result of a user interaction and reducing a size of the upcoming portion of the content stream in accordance with the prioritizing. The reducing comprises decreasing the frame rate of the video content.

A server system assigns a group of user sessions to a single modulator. The user sessions comprise data in a plurality of classes, each class having a respective priority. The plurality of classes includes, in order of priority from highest priority to lowest priority, audio data, video data, and user-interface graphical elements. The server system determines that an aggregate bandwidth for a first frame time exceeds a specified budget for the modulator. In response to determining that the aggregate bandwidth for the first frame time exceeds the specified budget, the server system transmits an allocated portion of the data for the group of user sessions through the modulator onto a channel corresponding to the modulator during the first frame time in accordance with the class priorities.

A server remote from client device executes an HTML-based virtual client application. Using the HTML-based virtual client application, the server renders an image corresponding to a video frame. The rendered image includes HTML commands. The server generates an HTML wrapper for the rendered image. Generating the HTML wrapper includes converting the HTML commands to HTML primitives that are selected from a subset of available HTML commands. The server sends the HTML wrapper to the client device to be processed by an HTML-based application on the client device to enable the image to be displayed.
