A broadcast time resource allocation method and device

Abstract

The invention provides a radio time resource allocation method and a radio time resource allocation device which are applied to a digital multimedia wireless radio transmission system which is provided with multiple radios and multiple carrier frequencies shared by the multiple radios. The method comprises the following steps: determining the radio priority of each radio in time resource allocation according to preset radio priority determining rules, and determining the carrier frequency priority of each carrier frequency according to preset carrier frequency priority determining rules; determining the carrier frequencies occupied by each radio according to the number of carrier frequencies required for each radio, the radio priority and the carrier frequency priority; and sequentially determining time resource allocation of each radio on the carrier frequencies occupied by the radio according to the order of radio priority, the total time resource request of each radio and the carrier frequencies occupied by each radio. The invention mainly provides a flexible allocation result based on different requirements of a variety of radios in aspects such as capacity, number of carrier frequencies transmitted and the minimum frame length, in order to realize coexistence of a variety of wireless radio systems and effective transmission.

Description

technical field [0001] The present invention relates to the field of broadcast transmission, in particular to a method and device for allocating broadcast time resources. Background technique [0002] With the rapid development of digital multimedia wireless broadcasting and the increasing demand for broadcasting and television services, my country's wireless broadcasting and television is changing from the first standard based on the terrestrial digital TV multimedia broadcasting (DTMB) standard and China Mobile Multimedia Broadcasting (CMMB) standard. The standard system of the first-generation wireless broadcasting TV business is moving towards the second-generation wireless broadcasting TV business (including ultra-high-definition wireless TV broadcasting service, 3D TV wireless broadcasting service, wireless high-speed data push service and wireless hybrid TV service, etc.). At this stage, the international digital broadcasting industry is evolving towards the second-gen...
