    • Video analytics systems and methods are described that typically comprise a video encoder operable to generate macroblock video analytics metadata (VAMD) from a video frame. Functional modules receive the VAMD and an encoded version of the video frame is configured to generate video analytics information related to the frame using the VAMD and the encoded video frame. The downstream decoder can use the VAMD to obtain a global motion vector related to the frame, detect and track motion of an object within the frame and monitor a line provided or found within the frame. Traversals of the line by a moving object can be detected and counted using information in the VAMD and the line may be part of a polygon that delineates an area to be monitored within the encoded frame. The VAMD can comprise macroblock level and video frame level information.

    • An intelligent assisted transmission method is provided. In the method, a Multicast and Broadcast Service (MCBCS) Server transmits Multicast Broadcast Service (MBS) data to a base station in an MBS area. The base station transmits the MBS data to a user equipment. If the user equipment cannot correctly receive the MBS data, it returns a Not Acknowledgement (NACK) message to the base station. The base station transmits an intelligent assisted transmission prompt to the MCBCS Server. The MCBCS Server transmits an intelligent assisted transmission request to adjacent base stations of the base station. When the intelligent assisted transmission request is received, the adjacent base stations return an intelligent assisted transmission response. The MCBCS Server transmits the MBS data to the adjacent base stations, and the adjacent base stations transmit the MBS data to the user equipment.
    • 提供智能辅助传输方法。 在该方法中,多播和广播服务(MCBCS)服务器将多播广播服务(MBS)数据发送到MBS区域中的基站。 基站将MBS数据发送给用户设备。 如果用户设备不能正确接收MBS数据,则它向基站返回不确认(NACK)消息。 基站向MCBCS服务器发送智能辅助传输提示。 MCBCS服务器向基站的相邻基站发送智能辅助传输请求。 当接收到智能辅助传输请求时,相邻基站返回智能辅助传输响应。 MCBCS服务器将MBS数据发送到相邻的基站,并且相邻的基站将MBS数据发送给用户设备。
