A video codec is a software that will compress and decompress your raw video and audio into format which can then be transferred over the internet connection through the use of your IP — hence, Voice over IP. H is so popular because it increases the quality of the video while also being relatively inexpensive. H codecs is well known for being the standard for internet streaming websites, such as YouTube.
Benefits: HD High Resolution quality p 60fps eliminates most pixilation experienced with prior codecs. Bandwidth Consumption: kbps with overhead, k without. This particular codec is a compression format that was created by Google, and it works relatively well as a high quality and real time video streaming codec alongside your video conferencing conference.
It has its criticisms as being a codec that is buggy with an interface that seems incomplete, but however it is still a codec that offers encoding and decoding in a smooth, real time manner. It has much in common with H, and is just slightly below that particular codec in video quality. Bandwidth Consumption:. Another older version of internet video codec standard, H is not quite as obsolete as other older codec standards.
Perangkat ini dapat digunakan untuk mendefinisikan jalur dan aturan antar terminal. Beberapa jenis SoftSwitch juga menyediakan fasilitas tambahan untuk dapat berkomunikasi dengan SoftSwitch lain di internet. Ada beberapa SoftSwitch yang dapat anda pilih untuk membangun jaringan VoIP sendiri, semuanya memiliki lisensi gratis. Contoh dari VoIP server ini adalah Asterisk.
Packet Switch Telepon analog yang biasa digunakan di rumah menggunakan teknologi Circuit Switching. Konsep dasar penggunaan Circuit Switching yaitu sebuah jalur komunikasi akan dibuka dan dipesan selama terjadi komunikasi.
Jalur komunikasi yang ada akhirnya menjadi eklusif dimiliki oleh dua titik yang menggunakannya. Contoh, anda tinggal di Jakarta dan hendak menelepon kerabat yang berada di Surabaya.
Selama proses komunikasi antara anda dan kerabat terjadi, jalur telepon dari jakarta ke surabaya adalah eklusif milik anda dan lawan bicara. Alhasil biaya pun memebengkak karena anda harus membayar jalur telepon tadi.
Konsep berbeda ditawarkan VoIP. Seluruh data yang lalu-lalang di Internet menggunakan konsep Packet Switching.
Proses ini mengkonversi sinyal audio menjadi data digital yang dipadatkan kompresi untuk kemudian dikirim lewat jalur internet. Di titik lain, data dikembangkan lagi dekompresi , dan diubah menjadi sinyal analog.
Konversi codec bekerja dengan cara memotong bagian sinyal sampling audio dalam jumlah tertentu perdetiknya. Sebagai contoh, codec G. Jika data hasil kompresi berhasil diterima di titik lain, proses selanjutnya adalah melakukan perakitan ulang. Data yang dirakit tidak selengkap data saat pertama kali dikirim, ada beberapa bagian yang hilang. Akan tetapi bagian yang hilang sangat kecil sehingga tidak terdeteksi oleh telinga manusia. Codec juga bekerja menggunakan alogaritma tertentu untuk membantunya memecah,.
SoftPhone Selain berupa telepon utuh hardware , perangkat telepon juga bisa berbentuk software. Softphone memiliki jenis yang beragam baik dari kemampuan dan lisensi. Saat ini banyak Softphone yang disebarkan dengan lisensi gratis. Bahkan ada yang menyediakan lisensi software gratis sekalligus layanan jaringan VoIP-nya.
SoftPhone Skype ini hanya bisa bekerja di jaringan milik Skype. Jika ingin membuat jaringan sendiri harus menggunakan Softphone jenis lain.
Selain suara, X-Lite juga bisa digunakana untuk saling berkirim text dan video. No other system is as configurable like this. The original poster did not ask for consultation or a recommendation. He simply requested a feature enhancement for his existing scenario. The unit sends H. In fact, after significant researching, I have been unable to identify any door bell style commercial quality device that supports VP8. Now there is a case to be made for setting up additional extensions and having the users install GS Wave just for the doorbell, which to me is inelegant, or to dismiss the 3CX apps and focus on GS Wave, in which case I loose the provisioning control.
I did notice this on the 3CX website recently. If Grandstream cant add this codec due to hardware resources i get it. Does anyone knows other intercoms with this VP8 codec?
Also my understating is that mobile apps supporting only VP8. Did someone test it and support also H. I also looked at 3 oither brands of which I have some familiarity and none supported VP8, but all supported h. This is not to say my search was all encompassing and that there are not brands out there that do support VP8, but rather that the 3 I looked at are all major brands.
As far as the apps go, I guess it depends on what you may be looking at and how you envision using it. They both interact with the Intercom, but the GS app is also a softphone. The other 2 brands that I looked at do not offer an app, but rather rely on your choice of a SIP softphone app. Most of these support an h. There are debates about which is better, but it seems that from a video perspective most seem to lean towards h. However, there is something to be said for VP8 given that it is unlikely that either codec will carry their full stream capability across a mobile network such that it will be delivered to a handheld mobile device smaller screen so perhaps the technical difference is not that big a worry, but VP8 is royalty free which may give it a leg up for some manufacturers.
There was a similar post earlier this year where one was also inquiring about VP8. They also looked around and found no VP8 compatible intercoms. You might find something on Alibaba or other, but then it may be a question of the level of support you might need and can get. GDS supports h. That is not going to change. The 3CX app could easily support h. It is not a technical challenge, and mobile hardware does included h.
