摘要： In one embodiment, a method includes identifying a current encoding rate requested by a client device for content received from a content source, setting at a network device a rate limit to limit the rate at which the content is received at the client device based on the current encoding rate, and adjusting the rate limit based on changes in the current encoding rate. The rate limit is set to allow the client device to change the current encoding rate to a next higher available encoding rate.

摘要： The invention relates to a method, for controlling at least one path in a multipath environment by a path control entity, wherein the at least one one path is used for transmitting an encrypted video stream comprising a sequence of video segments. The method comprises the following steps: estimating a resolution used in the video stream based on the video segments, and determining that the resolution used in the video stream has changed during the transmission. When it is determined that the resolution used in the video stream has changed, an adaptation of a number of the at least one path used for transmitting the video stream in the multipath configuration is initiated based on the determined change of the resolution.

摘要： Disclosed herein are systems and methods for implementing model-based quality-of-experience (QoE) scheduling. An embodiment takes the form of a method carried out by at least one network entity. The method includes receiving video frames from a video sender, which had first annotated each of the frames with a set of video-frame annotations including a channel-distortion model and a source distortion. The method also includes identifying all subsets of the received video frames that satisfy a resource constraint. The method also includes selecting, from among the identified subsets, based at least in part on the video-frame annotations, a subset that maximizes a QoE metric. The method also includes forwarding only the selected subset of the received video packets to a video receiver for presentation.

摘要： A data path control device (1) is provided with the first interface section for connecting to a LAN, second interface section for connecting to an external network through a small transmission capacity two-way line such as a telephone line, and third interface section for receiving a large capacity data from a large transmission capacity one-way line such as a satellite broadcast line. The data path control device changes the sender address of the data transmitted from a computer to a network based on a previously set correspondent relation, thereby controls the path so that the large capacity data from the network is transmitted through the large transmission capacity one-way line. A path of the reply data from a network respondent to the request data from a computer outputted to an external network is selected by the computer side, and in the case that the reply data is composed of large capacity data, a satellite line having a large transmission capacity can be selected.

摘要： A method includes exchanging signaling between a first entity providing access by a user equipment to a video stream and a second entity through which the video stream passes prior to being delivered via wireless transmission to the user equipment, the second entity receiving video information corresponding to the video stream, the exchanged signaling associated with the video information received at the second entity. Responsive to the exchanged signaling, sending information from the first entity to the second entity to modify status at the second entity of at least a portion of the video information previously received at the second entity. Another method includes at the first entity, receiving from a second entity an indication the second entity is capable of accepting multiple resolutions of a video in the video stream. Responsive to the received indication, the first entity sends to the second entity multiple resolutions of the video.

摘要： A network and method for efficiently and effectively acquiring broadcast content, such as multimedia data, from content providers (24) and delivering the acquired content to end users via a tiered network (12) to minimize congestion during content delivery to thus provide high quality of service. The network and method employ a tiered Internet-based network that is served by a hybrid satellite/optical fiber data distribution network. The network includes a data center (18) to which data, such as streaming video, audio or multimedia data, is provided over a content acquisition network by content providers. The data center uplinks the data to at least one satellite, such as a geosynchronous earth orbit (GEO) satellite, and over an Internet or asynchronous transfer mode (ATM) network (30), which distributes the data to the servers in the tiered network (12). The tiered network in this example comprises three tiers, although any number of tiers is acceptable. The three tiers are referred to respectively as master data centers (master data center tier) (18), regional data centers (regional data center tier) (16), and media serving centers (media serving center tier) (14) that are interconnected by a private asynchronous transfer mode (ATM) network. A data director in the data center in cooperation with the ATM network determines which tier of servers can best fulfill a data request by an end user while minimizing the amount of hops required to provide such data.
