SIMO (single-input multiple-output) type HDMI (high-definition multimedia interface) distributor device

Abstract

The invention belongs to the field of electronic techniques, and relates to a SIMO (single-input multiple-output) type HDMI (high-definition multimedia interface) distributor device. The input end of a HDMI signal input unit introduces signals from a high-definition signal source, and the output end of the HDMI signal input unit is in electric information communication with a port processor unit; the output end of the port processor unit is in electric information communication with a one-input two-output processor unit, and outputs signals to the one-input two-output processor unit to carry out one-input two-output type distribution, then the one-input two-output processor unit is respectively connected with and transmits the signals to the next stage of two one-input two-output processor units connected in parallel to carry out one-input two-output type distribution again, and then the two one-input two-output processor units connected in parallel respectively carry out one-input two-output type signal distribution again; and through carrying out sequential repeated logical connection, an effect of SIMO type signal distribution is achieved. The SIMO type HDMI distributor device is novel and simple in structure, reliable in principle, good in distribution performance, low in application cost, low in energy consumption, and environment-friendly.

Description

Technical field: [0001] The invention belongs to the technical field of electronic signal processing, and relates to a splitter capable of dividing a single signal input into multiple outputs and supporting the work of multiple terminal devices of different models and performances, in particular to a single input multiple output HDMI Dispenser device. Background technique: [0002] At present, the advent of the high-definition era has driven the development of digital interfaces. High-definition multimedia interface (HDMI) is a transmission interface developed for the next generation of multimedia audio-visual equipment. The HDMI interface can provide data transmission bandwidth up to 10.2Gbps, and can transmit uncompressed Audio signals and high-resolution video signals, without the need for digital / analog or analog / digital conversion before signal transmission, can ensure the highest quality audio and video signal transmission. At present, consumers are troubled by variou...

Problems solved by technology

AFSP108 / 112HDMI splitter is developed in response to market requirements. It can expand one signal to eight / twelve signals and output simultaneously with various high-definition signal sources, and provide high-definition demonstration equipment with video signals up to 1080P to fill the gap in the market. To meet the needs of the market, there are VGA splitters, component splitters and HDMI splitters according to different input signals. The first two are analog signals, and the latter is digital signals, so the transmission quality of HDMI splitters is higher. According to the number of output channels How many are divided into 4-way, 8-way, 12-way and 16-way distributors, etc. HDMI supports EDID and DDC2B, so HDMI devices have the characteristics of "plug and play", and the signal source and display device will be automatically connected. "Negotiation" automatically selects the most suitable video / audio format; because HDMI transmits sound and video at the same time, the connection is more convenient; according to the supported HDMI signal standards, it is divided into HDMI1.2, 1.3 and 1.4, currently on the market Most of them use HDMI1.2, do not support 3D signal transmission, poor compatibility, do not support Blu-ray disc players, and seek to develop a HDMI1.4 splitter that can not only support various streamers and Blu-ray The use environment of DVD, and support the use environment of various players at the same time, to fill the application gap
