What is a video distributor encoder?

Explanation:

If a video signal is sent to multiple devices (for example, a camera image is sent to a matrix or DVR), it cannot be directly separated. A dedicated video device is used as a video distributor. Video distributors are divided into 1 minute 2, 1 minute 3, 1 minute 4, 1 minute 8 ...!

One video signal is divided into multiple places for viewing

Encoder:
Encoder is a sensor that converts angle and length signals into encoded digital signals.
Features: High Accuracy, fast response, large measurement range, small size, light weight, easy installation, simple maintenance, and stable operation.

Definition of Encoder
Definition 1:
1) encoder refers to a circuit that can be used to express information with a certain meaning. 83 encoder has an output end.
2) The one-bit calculator is an arithmetic circuit that can realize the addition of two binary numbers and three numbers from carry-on signals.
Definition 2:
An Encoder is a device or process that completes encoding... a decoder is a device or process that completes decoding.
Definition 3:
A device that converts analog data such as speed, position, and angle to digital data is called an encoder. the commonly used encoder in the past is a photoelectric encoder shown in 41.
It is composed of Light Emitting Diode (light emitting element), photosensitive transistor (receiving element), with a certain number of gaps in the code disk and related circuits installed in the motor together (where the rotating axis of the motor rotation axis)
Definition 4:
The former includes multiple-rate pocsag bitstreams, flex bitstreams, and the corresponding two-level or four-level is called encoder.
The latter adjusts the output modulation of the encoder. After the carrier frequency is amplified, the encoder and the encoder are independently controlled by the microprocessor.
Definition 5:
The digital circuit used to complete the coding task is called an encoder. 1. a binary code of a binary encoder contains two types: 0 and 1, which can represent two signals.
Two binary codes are available: 00, 01, 10, and 11, which can represent four signals.
Definition 6:
It is worth mentioning that the output signal of the incremental encoder (hereinafter referred to as the encoder) is in the form of a pulse, which is also called a pulse generator,
It is more suitable for connecting devices with excellent performance such as CPLD and DSP.

 

 

:
Hardware (encoder/decoder) for converting audio or video signals between analog and digital formats; hardware or software for compressing and extracting audio or video data (compression/decompression ); or a combination of encoder/decoder and compression/decompression. Generally, the decoder can compress Uncompressed Digital data to reduce memory usage.

Decoder is a hardware/software device that inputs analog video signals and converts them into digital signal formats for further compression and transmission. Video MPEG4, audio MP3, AC3, DTS, etc. These encoders can compress and store the original data. These encoders are commonly used encoding formats and some professional encoding formats, generally, it is not used by families. Decoding software is usually called a plug-in to replay these videos and audios on a home device or computer. For example, MPEG4 decoding plug-in ffdshow and AC3 decoding plug-in ac3fliter. Only a computer with various decoding extensions can replay these images and sounds.
