The records coding method embraces 8B/10B programming, via which just a Differential Signal Pair is actually needed to have to broadcast information as well as time clock at the same time. The adapter is made up of 4 sets of differential indicator series, or even 4 major stations, which are actually made use of to broadcast graphic records. The hookup can easily enhance the stability of the major stations and also lessen records inaccuracies, as well as it may recompense the variation of electricity residential property induced through various size as well as kinds of wires, particularly the distinction of indicator directing on the unit panel of the sending end and also the acquiring end.
The information coding procedure takes on 8B/10B programming, with which just a Differential Signal Pair is actually needed to have to send records and also time clock concurrently. The adapter is made up of 4 sets of differential indicator series, or even 4 primary stations, which are actually made use of to send picture records. The hookup may boost the integrity of the principal network as well as decrease information inaccuracies, as well as it can easily recompense the distinction of electricity residential property triggered through various span and also kinds of cable televisions, specifically the distinction of indicator directing on the unit panel of the transferring end and also the getting end.
The ADP interface signal consists of three parts: Main Link, Auxch and HPD, as shown in the following figure.
There are actually 3 Key parts: Key Web link, AUX CH, as well as HPD
The Key Hyperlink stands for the Key network for the gear box of all forms of video clip and also sound information, and also AUX CH stands for the supporting stations for the gear box of information along with reduced data transfer criteria, along with Web link control as well as tool management indicators HPD embodies the hotplug diagnosis network.
Key Link contains 1-4 sets of information pipes, each set of information pipes are actually a set of variation pipes. 1) taking on a/c combining modern technology, the recipient as well as the transmitter possess various common-mode currents, so the user interface could be produced smaller sized; 2) the present gear box price of each pipe is actually: 1.62/ 2.7/ 5.4 Gbps; 3) each records pipe is actually information pipe, no time clock pipe, lower EMI; 4) making use of ANXI8B/10B code, enhance records gear box reliability.
For an LCD display, the Main Link needs many sets of information product lines, depending upon the settlement of the monitor and also the lot of colour littles.
The signs broadcast in the network consist of video clip pixel sign, video clip time sign, video clip style shade, bit/pixel as well as indicator room sign as well as mistake adjustment sign of online video sign, anxi 8b/10B html coding is actually made use of to strengthen the reliability of information gear box. Records gear box makes use of air conditioner combining modern technology, obtaining and also delivering end possess various common-mode current, thus may produce the user interface much smaller.
POINTER: ANSI8B/10B programming is actually to sort a team of 8-bit information right into 2 teams, a team of 3-bit, a team of 5-bit, and after that after coding, a team of 4-bit, a team of 6-bit binary information.
AUX CH: made use of to transfer records for tiny transmission capacity needs, hyperlink control, as well as gadget management
It is actually a bi-directional half-duplex gear box stations, whose indicator is actually broadcast through ac-coupled differential gear box, as well as whose indicator is actually inscribed through MANCHESTERLL, along with the gear box cost of lMbps and also the gear box range of 15m. EDID for lengthy show recognition information, made use of to save show specifications, as well as DPCD for EDP user interface setup records, hooked up to connect control coating for hyperlink setup.
HPD is actually a one-way stations, which is actually utilized to identify whether the e-layer tools and also the reduced tools are actually hooked up, and afterwards recognize the relationship as well as interrupt of free throw line.
How Main Link selects the number of Lane
The number of Lane required is based on the screen resolution and color depth.
NOTE: 1Lane can transmit 1.62 g * 8/10 = 1.296 Gbps if the data rate is 1.62 Gbps and only applies to one lane, while 1Lane can transmit 2.7 g * 8/10 = 2.16 Gbps if the data rate is 2.7 g * 8/10 = 2.16 Gbps
Bit rate requirement = pixel of clock rate * pixel depth (BPP) ;
In EDP, the Pixel of clock rate is fixed and can be obtained by table lookup.
For example, a 1080P@60hz LCD screen,
The minimum bandwidth required for transmission is 148.5 * 24 = 3.564 Gbps,
so a minimum of 2 lane = 4.32 Gbps > 3.564 Gbps is required
