2. Firmware duas habemus in fulciendo et encoder et decoder.
Non video encoder decoder auxilium HD-SDI? 1080p vel 1080i.
1. Max sustinet 1080P.
2. HDMI input supports 4k.
Possuntne encoder cum quovis h264/h265 decoder i.e . compatitur. Nvidia jetson decoder etc
Non opus est quaerere fectum, Quaeso dic nobis singula de video decoder si habes.
Etiam habemus tabulam encoder et decoder, si ambo nobis, tum est dubium.
Nam 4k vel 1080p video quid erit notitia rate ethernet??
Video bitrate configurable a elit (user).
Nos utemur tabula tua video encoder cum duobus input (HDMI et PAL) et cum 12V alimentatione. Bene est?
Vis HDMI vel AV input (Duo genera video support), vel HDMI et AV opus est ut duo simul inputs sustineant?
Q,: Non opus est HDMI et AV habere duas inputationes simultaneas.
A: Bene. Firmware fabrum nostrum aliquot dies faciet ut novam firmware occursum huic functioni quam debes. Ego upgrade et ostendam tibi test video. https://youtu.be/izdFa1nw7u8
iVcan: Placet auxilium ad confirmandum HDMI et cvbs simul sustineri posse, sed audio tantum e duobus unum seligi potest (systema eligat HDMI audio / analogon audio secundum accessum video situ), est ok ad vos?
clientem: Non opus est nobis audio, ut quod optimum est tibi.
iVcan: Noster software engineer fecit a software pro vobis. Placere reprehendo in imaginibus attachiamentorum.
Nunc HDMI cameram et CVBS cameram sustinet.
clientem:
Te encoder multiplex temporibus cum systemate nostro tentavi. Est denique altiore opus est.
Sed unum magnum exitum habemus, ut eius usus convalescere possit :
Quoties in systemate Camera venimus et simul encoder nos legere non possumus “mainStream”, non possumus tantum legere “subStream”.
Debemus “Reboot” in encoder per interface tela ut opus sit: postquam reboot possumus directe legere mainStream.
Conati sumus cum utraque VLC et GStreamer.
Quid conamur habere ambo rivos readable in startup ?
iVcan:
In fabrum nostrorum sententia, Difficultas est vel cum camera recognitionem vel Difficultas in usu mos.
Suspicor tabulam card non agnoscentis HDMI camera emptoris.
Hoc facile est cognoscere (si non potes accedere ad sub-amnis, erit difficile cognoscere).
Stipes in ad servern interretialem tabulae encoder et cameram agnitionis status in pagina electronica videre potes.
iVcan:
Pagina video tantum agnitionem status unius camerae ostendet. Si HDMI et AV camerae simul connexae et recognitae sunt, pagina video recognitionem status camerae HDMI exhibebit (ut 1080p60):
Quamdiu HDMI camera potest agnoscere Northmanni, Potest accessed Northmanni amet.
Si HDMI camera cognoscitur plerumque, Quaeso reprehendo HDMI wiring et potentiam in tabula iterum (nota quod haec est potentia cycli, non sileo in pagina interretiali)
Autem, tabula temere Mac oratio utitur, sic Mac oratio mutabit omni tempore nos sileo it.
Nam cogitationes cum ARP cache (ut a PC *), post restarting, erit tempus (brevi tempore) posse accedere ad tabulam de network. , Ad eam accedere non possumus donec petitio arp re-initiata est post timeout (factum est ut coding tabula non pinged aliquot secundis post restarting)
Ergo, Suspicor aliam possibilitatem esse, cum mos accesserit amet, non potest accessed ex causis supradictis. Deinde cum Lorem accessibus sub-amnis, in ARP cache reficit ac elit accedere potest, sed Lorem non revisere pelagus-flumen.
“Whenever we turn on the system camera and the encoder at the same time, we cannot read the “Mainstream”, we can only read the “subStream”.“
iVcan:
Judging from your description here, it seems that your camera is started after our encoding board. Please start your camera first, and then power on and start our encoding board to try it. Maybe it is not powered on at the same time. The powered-on order also matters. eg, your camera startup needs 10 seconds, but our encoder board startup needs only 5 seconds.
Because I am not sure whether your camera is very slow to initialize after power-on.
Because our encoder board starts very quickly, it may be that the camera has not been initialized after it started our encoder board, which may lead to some unexpected problems. Hoc etiam explicari potest cur "Reboot" habemus encoder per interretialem interfaciendi ad operandum: post reboot possumus directe legere mainStream. ", quia cum pagina pagina tua encoder tabulam restarts, de camera iam initialized.
Ergo, ultima suggestiones sunt ut sequitur (Conatus sum operam meam enumerare omnia quae in mentem veniunt et te separatim probas);
Vide paginam interretialem interretialem et confirma num HDMI camera normaliter agnoscatur? (tortor potes mittere ad nos). Dum camera noscitur Northmanni, Accessed amet;
Commendatur ut tabula coding cum cmd primum, et deinde accessum mainStream et subStream sub vlc ad evitandam falso existimans amet non posse accessed ob quaestiones temere mac.
Te incipere camera prima (paucis secundis), tum potestatem et incipit nostram translitterandi tabulam temptare (vide causas supra scriptas)
Sequere tuam originalem operationem "converte in camera systematis et simul encoder".. Cum quaestionem "non possumus legere "mainStream", "subStream" legere possumus. repraesentetur, Noli sileo tabulam translitterandi per paginam interretialem, sed calidum-VERTO HDMI funem inter cameram tuam et tabulam descriptam. Puto tantum operationem calidum-VERTO (because I suspect it is a plug-in detection problem that causes the camera not to connect to the encoding board. Send HDMI signal).
clientem:
I can always read the subStream. The mainStream only after reboot.
iVcan:
Then our encoder board can detect your camera.
Please do a test.
Te incipere camera prima (paucis secundis), tum potestatem et incipit nostram translitterandi tabulam temptare.
The engineer worries about that your camera startup needs 10 seconds, but our encoder board startup needs only 5 seconds.
Please do this test to rule out the possibility of different startup times.
iVcan:
When you are testing, it is better to adjust the setting back (red words) or see the below picture.
clientem:
The encoder board and the camera are both powered on at the exact same time. It is likely that the camera startup takes a bit longer than the encoder board.
I confirm that the camera seems to be not recognized on startup “CVBS pal” is displayed at the top.
Pingo tabulam tenuis possum priusquam utrumque fluminum legere conatur
Quando incipit mea camera prima (paucis secundis), tum potentia on (15 seconds postea) ac satus modum translitterandi tabula, Non possum legere amnis sicut finis.
Ego si “conversus ratio camera et simul encoder ". Et tunc calidum plug HDMI (15 seconds postea), Non possum legere amnis sicut finis.
quid facere possim nisi quod ego horum legere possum? ? Mitte ad http petitionem reboot cum software ", brevi post satus ?
iVcan:
Bene, ut probatur recta coniectura mea. Pro nostris aliis customers, camera et tabula nostra descriptam omnes simul potestatem habent. Camerae nostram descriptam tabulam normaliter cognoscere possunt et HDMI signa emittere. Pauci tantum clientes eiusmodi difficultates inciderunt utentes suas HDMI cameras amet. Solvitur per se ipsum (modificare camera sua occasus / mutantur cameras).

Does your HDMI + CVBS video encoder board support ONVIF?
The engineer said that the ONVIF protocol is not fully supported. It depends on your specific requirements.
The video player supports RTSP, VLC, Easyplay, and protocol support UDP player.
Can I use hdmi stream and CVBS stream together?
Our video encoding board supports two channels of video at the same time, one is HDMI video stream and CVBS video stream encoding.
Quaeritur: Quod tempus proprium tuus DVB-T modulator (transfusor) habet? Infra videre possumus si vexillum DVB-T inspicimus ETSI EN . 300 744.
Quae autem tempora sunt in modulo tuo DVB-T TX??
Nobis opus est quia cogitamus frequentiam velocis-mutationis in video streaming, sic nos oportet intelligere vera tempora ad hunc modum. QPSK utimur, CR=1/2, GI=1/32, Sed = 8 MHz.

cvbs converter ad IP, av signo converter ad ethernet, SDI CVBS encoder,
Q,: How much will be the latency if I connect two cameras (HDMI + CVBS)?
I have two cameras, one is a hdmi camera, and the second is a CVBS camera. I will convert both video streams to IP ethernet by this board and the opposite receiver side will be a computer.
A:
The delay of the video encoding board must take into account the encoding and decoding. It is impossible to test the accurate delay from the encoding board alone.
plerumque, the delay caused by the decoder board is greater.
With different software players, the latency varies greatly. eg, using our Splayer the delay is about 100ms, and using VLC the delay can be up to 300ms.
The delay of the CVBS camera is difficult to measure accurately. Delays below 100ms are difficult to measure with a stopwatch. Autem, the delay of Vcan1681 itself is not easy to test. Without the decoder board, you can’t even see the image. It cannot be calculated by using a stopwatch, and there is no way to measure it with an oscilloscope.
After the customer buys the encoding board, he will definitely need a player to decode. Then it is better to ask the customer what kind of player he plans to use for decoding (ours, the customer’s own, or a third party), so that we can know better whether the coding board can meet customer requirements (function and performance) or not.
How to test the video encoder board latency?
- I pointed the camera at the stopwatch on my computer screen.
- Another computer plays the video sent from the current encoding board and also displays the stopwatch on the computer screen.
- You need to reduce two times, namely the delay from the camera to the monitor. (Including camera and screen delay)
- Please check the below pictures
Q,: How much is the latency if I use your encoder and decoder board?
A: It is better to use our encoder and decoder board. The encoder and decoder board prices is the same. The below latency test result is only for your reference, not including the camera delay.
- CVBS input to our encoder board—–our decoder board with HDMI output, the delay is 60~90ms
- HDMI input to our encoder board—–our decoder board with HDMI output, the delay is 90~130ms
- HDMI 720P input our encoder board——–our decoder board with HDMI output, the delay between 80~100ms
- HDMI 1080P input our encoder board——–our decoder board with HDMI output, the delay between 100~130ms
