Link task processing method and device

Abstract

The invention discloses a link task processing method which comprises the following steps: sorting flows from high to low according to the current priorities of the flows when receiving an execution request initiated by at least one flow to the same link task, and generating a first queue from identifiers corresponding to the flows according to the sorting result; according to the sorting result of the first queue, distributing resources required for executing the link task for the flows corresponding to the identifiers in sequence; and notifying the flows distributed with the resources to execute the link task, and deleting the identifiers of the flows from the first queue, wherein the current priority of each flow is determined according to the following steps: receiving a priority selection instruction input by a user, and obtaining a subjective priority corresponding to the priority selection instruction; and determining the current priority of the flow according to the subjectivepriority and a predetermined objective priority corresponding to the flow. The invention further discloses a link task processing device. The objective priority adaptive to a flexibility requirement is provided by using the link task processing method and device, so that the resources can be effectively utilized.

Description

technical field [0001] The invention relates to the field of workflow-based media asset management systems, in particular to a link task processing method and a link task processing device. Background technique [0002] The media asset management system based on workflow control is mainly used to support the integration of TV stations’ production and broadcasting services. It is one of the core application platform systems of TV stations. Its main functions include: 1) Processing programs through uploading business processes, storing The finished program and material content of the whole station of the TV station; provide shared channels to all business departments of the whole station through the download process; 2) Integrate the TV station's production business section, central media asset business section, chief editor and broadcast preparation business section and broadcasting business through the process channel plate. The TV station’s media asset management system ca...

[0010] In addition, since the business volume of the media capital platform is uncertain, within a unit time, the higher the business volume, the greater the business pressure, and the lower the business volume, the lower the business pressure. See figure 2 Provided business volume pressure diagrams at different times, where the larger the number, the greater the business pressure, from figure 2 It can be seen from the figure that the system resources cannot meet the business pressure at all times. Although the existing system resources can meet the average business pressure per unit time, they may not be able to meet the business pressure exceeding the average business pressure. , especially when the current business pressure reaches the peak line of business pressure, system resources cannot meet the business pressure

If the processing strategy is allocated according to the existing priority, the resource utilization rate is not high in some time periods, and the resources cannot meet the business pressure in some time periods, and even some processes cannot be carried out, which seriously affects the process of the TV station. For example, When the download process of media assets for urgent download is ready to be broadcast, if the transcoding link cannot obtain resources in time and stagnates, it may not be possible to complete the download process of media assets to broadcast before the limited time of the broadcast preparation program. eventually affect the broadcast
