    摘要： Example implementations involve systems and methods for determining bandwidth savings from a rate-limiting process. A network optimization node can determine a first reference characteristic of a first portion of adaptive bit rate (ABR) media data transmitted from a first content provider to a first user equipment while rate-limiting is disabled and store in an estimation module database associated with the network optimization node, the first reference characteristic in association with the first content provider. The node can determine a first rate-limited characteristic of a second portion of the ABR media data transmitted from the first content provider to at least one of the first user equipment and a second user equipment while rate-limiting is enabled and calculate a first bandwidth savings for the first content provider associated with rate-limiting being enabled based on a difference between the first reference characteristic and the first rate-limited characteristic.

    摘要： Systems, methods, and non-transitory computer-readable media can identify a set of participants in a group video call, wherein each participant is associated with an uplink capacity and a downlink capacity, and the set of participants includes a set of sender participants and a set of subscriber participants. For a first sender participant of the set of sender participants, one or more video stream layers to be uploaded by the first sender participant are determined based on downlink capacities of one or more subscriber participants of the set of subscriber participants. Each subscriber participant of the one or more subscriber participants is assigned to receive one video stream layer of the one or more video stream layers to be uploaded by the first sender participant.

    摘要： The invention generally relates to tools for providing shorter media content previews having smaller file sizes to allow for audiences to preview media before or during downloading of the complete file. Methods are provided for intelligent selection of key content portions for inclusion in abridged previews. Interactive previews capturing the scope of the complete content but reducing file size through reduced frame-rates, compression, and/or resolutions are also disclosed.

    摘要： A wireless communication device includes a processor, a display device coupled to the processor, and a memory accessible to the processor. The memory includes instructions executable by the processor to perform operations. The operations include receiving a user input to play a media content item. The operations include sending a request for a summary of the media content item to a network device in response to the user input in lieu of sending a particular request for the media content item. The operations also include, in response to the reply including media content, sending the media content to the display device for display.
