摘要： A channel merging method for a VOD system, said method comprises the steps of: in response to requests from a plurality of clients for a video program, establishing a root channel (S1) and at least one sub-channel (S11), said root channel (S1) being established according to a request from a client that makes the earliest request, each of said sub-channels (S11) being established in response to a request from a client that makes a later request; and monitoring variation of the number of the clients that are using each of said established channels, and maintaining the channel if the number of the clients using the monitored channel is not zero, and closing the channel if the number of the clients using the monitored channel becomes zero.

摘要： The invention provides an information polling method, apparatus and system thereof, wherein a message gateway receives an information polling request from an application in an application client, and according to the received information polling request, the message gateway acquires at least one message requested by the application and calculates a reference polling cycle of the application, and sends the acquired message requested by the application and the reference polling cycle to the application. The application determines a polling cycle of a next poll according to a load condition of the application client and the received reference polling cycle. According to the invention, efficiency and quality of the information polling is improved, while the system is ensured to run normally, reducing the cases of message blocking and system breakdown which may occur in the existing situations.
摘要翻译：本发明提供了一种信息轮询方法，装置和系统，其中消息网关从应用客户端中的应用接收信息轮询请求，并且根据接收到的信息轮询请求，消息网关获取至少一个由应用并计算应用程序的参考轮询周期，并将应用程序请求的获取的消息和参考轮询周期发送到应用程序。应用程序根据应用客户端的负载条件和接收到的参考轮询周期确定下一个轮询的轮询周期。根据本发明，提高了信息轮询的效率和质量，同时确保系统正常运行，减少了在现有情况下可能发生的消息阻塞和系统故障的情况。
