    • System(s) and method(s) are provided to route data within a network of content with specific service constraints to mobile devices. A mobile network management component receives an identifier (ID) of a base station that serves a mobile device that originates a request for data, and relays the ID to a network platform that administers content. A mapping that associates one or more base stations with a deployed content node and the received ID are utilized to identify a content node to serve the request for data via the base station. The received request for data is directed to the identified content node. A service constraint configuration can be allocated for exchange of payload data between the mobile device and the network platform. For a request to consume data and a request to supply data, identified content node delivers data and receives data, respectively, in accordance with the service constraint allocation.
    • 提供系统和方法以将具有特定服务约束的内容的网络内的数据路由到移动设备。 移动网络管理组件接收服务于发起数据请求的移动设备的基站的标识符(ID),并将该ID中继到管理内容的网络平台。 将一个或多个基站与部署的内容节点相关联的映射和所接收的ID用于识别内容节点以经由基站来服务于数据请求。 所接收的数据请求被引导到所标识的内容节点。 可以分配服务约束配置用于在移动设备和网络平台之间交换有效负载数据。 对于要求消费数据和提供数据的请求,所识别的内容节点分别根据服务约束分配传送数据和接收数据。

    • A method and system for maintaining the quality of video transported over wireless channels uses a transcoder to modify and maintain the optical resilience of an encoded bitstream. The transcoder increases the spatial resilience by reducing the number of blocks per slice, and increases the temporal resilience by increasing the proportion of I-blocks that are transmitted in each frame. Also, the transcoder maintains the same input bit rate by dropping less significant coefficients as it increases resilience. The transcoder of the present invention maintains the resilience at an optimal level to accommodate the prevailing channel conditions as measured by the BER of the wireless channel. Rate distortion theory is applied to determine the optimal allocation of bit rate among spatial resilience, temporal resilience and source rate, where it is has been found that the optimal allocation of the present invention (which occurs in near-real time) provides nearly the same result as doing an exhaustive search.
    • 用于维持通过无线信道传输的视频的质量的方法和系统使用代码转换器来修改和维持编码比特流的光弹性。 代码转换器通过减少每个片段的块数来增加空间弹性,并且通过增加在每个帧中发送的I块的比例来增加时间弹性。 此外,代码转换器通过在增加复原力的同时降低较不重要的系数来维持相同的输入比特率。 本发明的代码转换器将弹性保持在最佳水平以适应由无线信道的BER测量的主要信道条件。 应用速率失真理论来确定空间弹性,时间弹性和源速率之间的比特率的最佳分配,其中已经发现本发明的最佳分配(以近实时发生)提供几乎相同的 结果是做一个详尽的搜索。
