A method of SDIOverIP multiplexing port data

Abstract

The invention discloses a method of SDIOverIP multiplexing port data. The specific operation method is as follows: (1) starting a client process for acquiring SDIOverIP port data, judging whether there is a server process of a corresponding port, if there is no server process of a corresponding port, entering a step (2), starting a server process, and entering a waiting state for acquiring data; If the server process of the corresponding port already exists, entering the step (3) and waiting for obtaining the data state; (2) acquiring SDI data through the SDIOverIP acquisition card and converting the data into an exchange file or a shared memory by the server process; (3) obtaining SDI data from the swap file or shared memory by the client process . The invention has the advantages of effectively simplifying the topology structure, reducing the fault links and reducing the input of additional equipment.

Description

technical field

[0001] The present invention relates to the related technical field of audio and video data application processing, in particular to a method for SDIOverIP multiplexing port data. Background technique

[0002] At present, the transmission and processing of multimedia audio and video in the traditional broadcasting industry is gradually moving towards network IP. The SDI signal transmission method collected by the program source is directly connected by the original SDI cable, and needs to be transformed into SDIOverIP network optical fiber transmission. After the relevant program production department receives the SDIOverIP source, it generally converts it into the corresponding SDI source first, and then enters the production department or pushes it to different departments and platforms. The problem now is to convert the collected SDIOverIP signal into one SDI signal. If you want to distribute this SDI signal, you must add an SDI splitter or use multiple di...

Examples

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as figure 1 In the described embodiment, a method of SDIOverIP multiplexing port data, the basic framework of the method is based on Client / Server construction, including Server end and Client end,

[0018] The server side is specifically: convert the collected SDI data to the SDI data storage format through the SDIOverIP capture card, and store them in the form of exchange files or system shared memory; the SDI data storage format includes frame serial number, frame media information and audio and video data; frame media Information refers to audio and video information, where video information includes width, height, frame rate and image data format, audio information includes sampling rate, number of channels and bit depth; audio and video data includes data size and data blocks of audio data and video data The data size and dat...
