Multiservice frequency assignment method and system for dual-mode terminal

Abstract

The invention discloses multiservice frequency assignment method and system for a dual-mode terminal. The method is used for reasonably assigning cable digital television network frequency bandwidth for the DVB/IP (digital video broadcasting and internet protocol) digital television dual-mode terminal and guaranteeing normal service of terminal multi-services. The method includes: when a frequency management unit assigns a certain service-type frequency for the terminal, searching tuner status information and service utilization information corresponding to the dual-mode terminal, and assigning proper frequencies for services of the dual-mode terminal; if an idle turner in the dual-mode server occurs, assigning a frequency meeting the service demanded bandwidth for the dual-mode terminal; and if no idle turner in the dual-mode terminal occurs, switching a service on the original frequency and a newly applied service to a same frequency, and returning frequency switching information. The tuner status information includes tuner number, frequency information locked by tuners, and service information corresponding to the tuners.

Description

technical field [0001] The invention relates to the field of cable television network bandwidth resource management, in particular to the technical field of cable television network multi-service frequency point bandwidth allocation, and in particular to a multi-service frequency point allocation method and system for a dual-mode terminal. Background technique [0002] The dual-mode terminal refers to the application layer software based on the IP protocol loaded on the basis of the hardware structure of the existing digital TV terminal. By integrating the relevant Ethernet interface in the same terminal, the same processing chip is used to complete the digital TV signal. As well as the information processing of IP content, the same remote control is used to realize the integration of different services on the same platform. In short, it is one machine with two networks: IP network and digital TV network. The meaning of dual-mode is that there are two working modes: IP chan...

Problems solved by technology

As mentioned above, currently there is only one tuner in mainstream digital TV dual-mode terminals, so to ensure that the terminal can use multiple services at the same time, it is necessary to send multiple service data to the terminal from the same frequency point, while the traditional frequency The point allocation algorithm does not consider the actual situation of the terminal tuner and the use of multiple services of the terminal, so when the number of tuners is limited, especially when the dual-mode terminal has only one tuner, a multi-service frequency point allocation method is designed to make multiple The business data is sent to the terminal from this limited frequency point, and ensuring the smooth use of multiple services by the terminal is a direction worthy of research
