摘要： A video coding system and method for increasing a transmitted output bit rate of a video encoding system by altering the content of the bit stream. A video encoder may receive a coding mode signal from a computer application for coding source video data, the coding mode signal indicating a target bit rate having a risk factor related to transmission error associated to the target bit rate. The coded bitstream may be modified based on the risk factor indicated in the coding mode signal. A modified coded bitstream may be outputted at the target bit rate and at a reduced coding efficiency, and the channel may be tested for transmission errors. Based on the test results, a revised coding mode signal indicating the same target bit rate, but a revised risk factor may be provided. The coded bitstream may be revised by removing the modifications previously made to the coded bitstream and a revised coded bitstream having greater coding efficiency may be output at the target bit rate.

摘要： Systems and methods for streaming video over multiple HTTP channels are provided. The client may have control over the channels, allowing the client to control the amount and source of data received. Data requested by the client may be separated into a set of layers, with each layer being assigned to a separate channel. The client may adjust the number of layers requested based on a variety of factors. Layers may be requested from multiple remote sources, providing the client with additional control over the specific bandwidth profile of received data.
摘要翻译： 提供了通过多个HTTP通道流式传输视频的系统和方法。 客户端可以控制信道，允许客户端控制接收到的数据的数量和来源。 客户端请求的数据可以被分成一组层，每一层被分配到单独的信道。 客户端可以根据各种因素调整请求的层数。 可以从多个远程源请求层，为客户端提供对接收到的数据的特定带宽简档的附加控制。

摘要： Some embodiments provide an architecture for establishing a multi-participant conference. This architecture has one participant's computer in the conference act as a central content distributor for the conference. The central distributor receives data (e.g., video and/or audio streams) from the computer of each other participant, and distributes the received data to the computers of all participants. In some embodiments, the central distributor receives A/V data from the computers of the other participants. From such received data, the central distributor of some embodiments generates composite data (e.g., composite image data and/or composite audio data) that the central distributor distributes back to the participants. The central distributor in some embodiments can implement a heterogeneous audio/video conference. In such a conference, different participants can participate in the conference differently. For instance, different participants might use different audio or video codecs. Moreover, in some embodiments, one participant might participate in only the audio aspect of the conference, while another participant might participate in both audio and video aspects of the conference.

摘要： Some embodiments provide an architecture for establishing multi-participant video conferences. This architecture has a central distributor that receives video images from two or more participants. From the received images, the central distributor generates composite images that the central distributor transmits back to the participants. Each composite image includes a set of sub images, where each sub image belongs to one participant. In some embodiments, the central distributor saves network bandwidth by removing each particular participant's image from the composite image that the central distributor sends to the particular participant. In some embodiments, images received from each participant are arranged in the composite in a non-interleaved manner. For instance, in some embodiments, the composite image includes at most one sub-image for each participant, and no two sub-images are interleaved.

摘要： Contents such as a GUI or application output can be shared in a chat environment. The user can choose to share own contents or request that contents be shared by another user (e.g., a chat partner). It can be possible to control the shared GUI or application from the recipient's location. The shared content can be integrated in content that is transmitted as part of a chat session.

摘要： Methods for establishing a direct peer-to-peer (“P2P”) connection between two computers are disclosed. In particular, the methods are designed to work in cases where one or both of the computers are connected to a private network, such private networks being interconnected via a public network, such as the Internet. The connections between the private network and the public network are facilitated by network address translation (“NAT”).
