摘要: Data is embedded onto new or existing media metadata tracks during playback of a media stream. A content server provides a media stream to a mobile device. Data associated with the playback of the media stream on the mobile device is obtained by the content server and saved to the media stream itself. Data may include playback statistics, viewing characteristics, channel changes, comment logs, etc. The information can be stored in a time-correlated manner to allow extraction and analysis of data.

摘要: A distributed and scalable content streaming architecture includes a plurality of controllers and a plurality of servers. The controllers are operable to establish Real-Time Streaming Protocol (RTSP) sessions with individual devices. A controller selects a server to provide a requested media stream to a device. The server may be selected based on its proximity to the device, bandwidth availability, or latency characteristics. The server transmits the media stream using a Real-Time Transport Protocol (RTP) and/or a Real-Time Control Protocol (RTCP). A controller can manage a number of sessions many times greater than the number of streams a server can provide, so a controller typically has access to multiple servers. Additional servers can be added to a system without disrupting system operation.
摘要翻译: 分布式和可扩展的内容流架构包括多个控制器和多个服务器。 控制器可操作以与各个设备建立实时流协议(RTSP)会话。 控制器选择服务器以向设备提供所请求的媒体流。 可以基于其与设备的接近度,带宽可用性或延迟特性来选择服务器。 服务器使用实时传输协议(RTP)和/或实时控制协议(RTCP)来发送媒体流。 控制器可以管理多个会话数量比服务器可以提供的数量多的次数,因此控制器通常可以访问多个服务器。 可以将额外的服务器添加到系统中,而不会中断系统操作。

摘要: Mechanisms are provided to detect device client capabilities associated with screen size, video and audio codec support, bandwidth limitations, and memory limitations. A content server can intelligently select a media stream for transmission to the device using the client capability information for the device. In some instances, the content server presents prioritized selections to a user and the user can choose the optimal media stream.
