Signal processing method and device for parallelly inputting multiple groups of video signals

Abstract

The invention proposes a signal processing method against a plurality of groups of parallelly input video information, a plurality of groups of video information signals are parallelly received, a plurality of groups of video information signals comprise at least a group of video information signals with a first horizontal resolution; a plurality of groups of video information signals are digitized and converted to a plurality of groups of video information data flows, wherein, at least a group of video information signals are digitized and converted to at least a group of video information data flows with a second horizontal resolution, the second horizontal resolution is less than the first horizontal resolution; a plurality of groups of video information data flows are transmitted to a digital device through a transmission interface connection port; and a third horizontal resolution plays images in the at least one group of video information data flows. The invention also comprises a device for implementing the method.

Description

technical field [0001] The invention relates to signal processing, in particular to a signal processing method and device for inputting multiple groups of video signals in parallel. Background technique [0002] Many applications involve the processing of multiple sets of video inputs in parallel. For example, the security monitoring system uses multiple cameras to capture real-time images of multiple specific scenes at the same time, and after appropriate processing, transmits them to an independent monitor or computer for real-time monitoring and / or video recording. [0003] For transmission to a digital device with a central processing unit such as a computer, it is usually achieved by using a commonly used transmission interface such as USB (Universal Serial Bus or Universal Serial Bus). These transmission interfaces have bandwidth limitations, so in order to monitor as many groups of images as possible in real time and record without loss, sometimes the images must be ...

Problems solved by technology

However, at the current technical level, for the most commonly used four-group video and the situation of more than four groups, it is still difficult to achieve without compression under standard image resolution (such as 360 x 240) and frame rate (framerate). satisfactory quality
