    • It is provided a method, device and system for transmitting an ACK response in bidirectional data transmission. When receiving windows on both sides of a transmission are simultaneously full, no new information frames can be transmitted to the other side before the ACK timer times out. This situation is called an ACK interlock delay. In the present disclosure, a communication device actively transmits a control frame carrying an ACK response to an opposite communication terminal when it detects that the local receiving window and the receiving window of the opposite communication terminal are both full, thus avoiding ACK interlock delays, avoiding wasting time, and improving the rate of transmission and link establishment.
    • 提供了一种用于在双向数据传输中发送ACK响应的方法,设备和系统。 当接收到传输两侧的窗口同时满时,ACK定时器超时之前不会向另一侧发送新的信息帧。 这种情况称为ACK互锁延迟。 在本公开中,当通信设备检测到相对的通信终端的本地接收窗口和接收窗口都是满的时,通信设备主动发送携带ACK响应的控制帧,从而避免ACK互锁延迟,从而避免 浪费时间,提高传输速度和链路建立速度。

    • A method for sending an ACK from the receiver to the sender is disclosed. The receiver starts an ACK timer with the ACK timeout value being smaller than the RTX timeout value. The ACK timer is stopped or cancelled when an ACK is sent from the receiver to the sender. When the number of the delayed ACK for I-frames is close to the receive widow size of the receiver or the ACK timer is timeout, the receiver sends an ACK to the sender actively. When the receiver receives a Poll frame from the sender due to RTX retransmission timeout, the receiver sends an ACK to the sender passively. The receiver adjusts the ACK timeout value used next time based on the following: timeout value of a current ACK timer, RTX timeout value of the sender, the receive widow size of the receiver and the number of I-frames for which ACKs have not been sent, in order to reduce the S-frames and stops of data transmission, thus improving the data transmission speed and the bandwidth utilization.
    • 公开了一种从接收机向发送方发送ACK的方法。 接收器启动ACK定时器,ACK超时值小于RTX超时值。 当从接收机向发送方发送ACK时,ACK定时器被停止或被取消。 当I帧的延迟ACK的数量接近于接收者的接收寡妇大小或ACK定时器超时时,接收方主动向发送方发送ACK。 当接收方由于RTX重传超时而从发送方接收到轮询帧时,接收方将被动地向发送方发送ACK。 接收机根据以下内容调整下一次使用的ACK超时值:当前ACK定时器的超时值,发送方的RTX超时值,接收方的接收寡寡大小和尚未进行ACK的I帧数 发送,以减少S帧和数据传输的停止,从而提高数据传输速度和带宽利用率。

    • A peer-to-peer novel video streaming scheme is described in which each peer stores and streams videos to the requesting client peers. Each video is encoded into multiple descriptions and each description is placed on a different node. If a serving peer disconnects in the middle of a streaming session, the system searches for a replacement peer that stores the same video description and has sufficient uplink bandwidth. Employing multiple description coding in a peer-to-peer based network improves the robustness of the distributed streaming content in the event a serving peer is lost. Video quality can be maintained in the presence of server peers being lost. The video codec design and network policies have a significant effect on the streamed video quality. The system performance generally improves as the number of descriptions M for the video increases, which implies that a higher video quality can be obtained with the same network loading.
    • 描述了一种对等小说视频流方案,其中每个对等体将视频存储并流向请求的客户端对等体。 每个视频被编码成多个描述,并且每个描述被放置在不同的节点上。 如果服务对等体在流媒体会话中间断开连接,系统将搜索存储相同视频描述并具有足够上行带宽的替换对等体。 在基于对等的网络中采用多描述编码改善了在服务对等体丢失的情况下分布式流内容的鲁棒性。 在丢失服务器对等体的情况下,可以维护视频质量。 视频编解码器设计和网络策略对流式视频质量有显着影响。 随着视频的描述数量M的增加,系统性能通常会有所提高,这意味着可以通过相同的网络负载获得更高的视频质量。

    • Improved distribution of video information in an infrastructure-based wireless network is provided. A wireless channel condition between the video server node and each of the plurality of receiver nodes is measured (or accepted, or otherwise determined). Each of the plurality of receiver nodes are assigned into one of a first group and a second group using the measured wireless channel conditions, wherein receiver nodes assigned to the first group have, on average (e.g., on average over time), a better measured wireless channel condition than that of receiver nodes assigned to the second group. At least some (e.g., one or more) of the receiver nodes of the first group of nodes are selected to serve as relay nodes. Video information (e.g., N layers) is then transmitted wirelessly from the video server node for reception by each of the receiver nodes assigned to the first group. Each of the selected relay nodes then transmit at least a part (e.g., M≦N layers) of the video information for reception by at least some of the receiver nodes of the second group such that the relay nodes collectively transmit the at least a part of the video information to all of the receiver nodes of the second group. Receiver nodes assigned to the first group receive, decode and render the received video information. Similarly, receiver nodes assigned to the second group, receive, decode and render the received at least a part of the video information. The receiver nodes assigned to the second group may also use the (1) video information transmitted wirelessly by the source node and/or (2) copies of the at least a part of the video information transmitted by other relay nodes (that is, relay nodes not assigned to it), to the extent such information is received.
