Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] figure 1 The flow of a sending method embodiment of the present invention is shown. Such as figure 1 As shown, initialization 101 is performed first. Encapsulate the data packet into an object, and set all the objects into the data structure of the linked list, where each object is a node of the linked list. The preset weight value of the object is set according to the usage frequency of the data packet, and the sum of the sending weight values ​​of all active objects and the sum of the preset weight values ​​of all objects are obtained. Then preprocess the program, including checking whether the linked list is empty, initializing the object sending weight, etc. After the initialization 101 is completed, start traversing the linked list nodes 102, first judge whether the current processing node is the tail node 103, when the tail node is proc...

Abstract

The invention discloses an asymmetrical data sending method, which enables the round-robin service to obtain more frequently used data at a decoding end to be analyzed more quickly under a fixed bandwidth, thereby optimizing the data acquisition speed. The technical solution is: comprising the following steps: a) setting respective preset weight values ​​according to the usage frequency of the data packets; b) traversing all the data packets, and setting respective The judging criterion weight value of the judging criterion weight value, select the data packet sending that judging criterion weight value is maximum simultaneously, and correspondingly reduce the judging criterion weighting value of described sending data packet; c) repeat step b), until described data packet is all sent. It is used in digital TV data transmission to improve the utilization efficiency of limited resources.

Description

technical field [0001] The invention relates to a method for sending asymmetric data, in particular to a method for sending asymmetric data by setting sending weight in advance in digital television software development. Background technique [0002] In the development of digital TV software, in order to improve the efficiency of sending data, data packets with different sending weights are usually set according to the frequency of data use, increasing the sending frequency of data packets with high sending weights, and reducing the sending frequency of data packets with low sending weights. [0003] Such a load balancing technology is currently widely used in computer networks. It provides a cheap and effective method to expand server bandwidth and increase throughput, strengthen network data processing capabilities, and improve network flexibility and availability. [0004] However, in the field of digital TV, there is no such technology to separately process data with dif...
