Problems solved by technology

At present, multimedia data transmission methods are generally only suitable for transmission under a single channel, and are not suitable for transmission under mixed channels.
When a single channel is used for transmission, the data transmission efficiency is low, and the pressure of single channel transmission is high, which cannot ensure normal data transmission

Embodiment 1

[0069] figure 1 It is a flowchart of a multimedia data transmission method under a mixed channel provided by Embodiment 1 of the present invention.

[0070] refer to figure 1 , the method includes the following steps:

[0071] Step S101, obtaining the remaining bandwidth of multiple channels;

[0072] Here, the multimedia data under the mixed channel adopts the multimedia data transmission method under the mixed channel for data transmission. Wherein, the mixed channel includes multiple channels, and the remaining bandwidth of each channel is obtained according to the bandwidth usage of each channel.

[0073] Step S102, according to the remaining bandwidth of each channel, the channels are arranged in order from large to small, and the arranged channels are obtained;

[0074] Here, in the process of arranging the channels, the more bandwidth remaining of the channel, the higher the ranking of the channel.

[0075] Step S103, detecting the occupied space of the data packet...

Embodiment 2

[0102] figure 2 It is a schematic diagram of a multimedia data transmission device under a mixed channel provided by Embodiment 2 of the present invention.

[0103] refer to figure 2 , the device consists of:

[0104] An acquisition unit 1, configured to acquire the remaining bandwidth of multiple channels;

[0105] The first arranging unit 2 is configured to arrange the channels in descending order according to the remaining bandwidth of each channel to obtain the arranged channels;

[0106] The first detection unit 3 is used to detect the occupied space of the data packets to be transmitted;

[0107] A search unit 4, configured to search from the arranged channels according to the occupied space of the data packets to be transmitted whether there is a channel matching the occupied space;

[0108] The first transmission unit 5 is configured to transmit the data packet to be transmitted through the found channel when it exists;

[0109] The second transmission unit 6 is...

Abstract

The invention provides a multimedia data transmission method and a multimedia data transmission device under a mixed channel. The method comprises the following steps: acquiring bandwidth surplus of a plurality of channels; arranging the channels from large to small according to the bandwidth surplus of each channel to obtain arranged channels; detecting the occupied space of the data packet to be transmitted; searching whether a channel matched with the occupied space exists in the arranged channels according to the occupied space of the data packet to be transmitted; if the to-be-transmitted data packet exists, transmitting the to-be-transmitted data packet through the searched channel; if the to-be-transmitted data packet does not exist, segmenting the to-be-transmitted data packet to obtain a plurality of segmented sub-data, and transmitting each segmented sub-data packet through a matched channel; according to the invention, the data packet can be simultaneously sent in a plurality of channels, and when the data packet occupies a large space, the transmission pressure of the channels can be relieved and the normal transmission of the data packet can be ensured by adopting a segmentation mode.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a multimedia data transmission method and device under mixed channels. Background technique [0002] Data transmission is to transmit data from the data source to the data terminal through one or more data links according to certain regulations. Its main function is to realize the information transmission and exchange between points. A good data transmission method can improve the real-time and reliability of data transmission. [0003] The data transmission part plays an important role in the whole system, which is equivalent to the nerves of the human body transmitting signals to various parts of the body. How to efficiently, accurately and timely transmit the digital information collected by the acquisition module is an important issue. [0004] Mixed channels generally refer to the fact that data passes through multiple channels, and according to factors such as th...
