More channels means more money for the techs, right?

smpte 2022 vidéo over IP network

Post by mirabelle mirabelle »

Hi every body,
I need more informations about SMPTE 2022 standards. I know that it contains 07 parts , each part define a spécific fonction.
For exemple SMPTE 2022-1 is about Forward correction
and SMPTE 2022-2 define how the vidéo is encapsulated in ip packets.

so in my project, i need to transport video from studio to the head end over telecom network

STUDIO Channel 1: Video MPEG4 CBR (6Mbps)

Headend Channel 1: Video MPEG4 VBR (1.8Mbps)

We need to buy encoders working with SMPTE 2022-1 and smpte-2 standards
my quastions is do I need also to put in my tender smpte-6 and spmte-7 standards????????????????????????????????????????????

Thank you

Just curious why you're hung up on SMPTE 2022 as a requirement?

We use off the shelf IP encoders from Fujitsu and Harmonic from several of our overseas bureaus using VPN tunnels over the public Internet with great success. Much less expensive, higher quality, and lower cost than satellite by any measure. I particularly like the reliability of the Fujitsu units, as they're able to react to lost packets better than the Harmonic IRD's. As a bonus, the Fujitsu comes with IP and ASI outputs standard. With Harmonic, the ASI output is an option, and can't function when used for IP too.

With either encoder/IRD combination, we can send up to 1080P-60 video with surround encoding as low as 10Mbps. If you go with broadcast HD, you can easily get away with 5Mbps, with no discernible loss of video quality.

SMTPE 2022 is more about uncompressed SDI over IP, you are talking about compressed video (a TS stream) over IP.
So just go for eg Ateme encoder with UDP/RTP output.

For the Harmonic encoders ask you Harmonic field engineer.

I remember that the old MV series encoders into Prostream 1000 only output ASI in the system that I had. On the other hand I believe that the Electra 8000 and 9000 series could do both at the same time. We just switched to the Electra X encoders about a week ago at WRC. We send ASI to the transmitters and distributors but I used the IP outputs to an Ineoquest monitoring system.

Encoder setups vary greatly depending on the requirements of the system. I installed a very different system using Harmonic encoders and Muxes at WUSA about 18 months ago. They also send ASI to their transmitter site and distributors. I think they also still use a little SMPTE 310 for and old exciter. (I have retired from NBC but I can do a little work for them and a little consulting down the street also.)

What Harmonic encoders can do is often determined by the licenses that you buy. Carefully determine what you need to do before pricing out a new encoder.

in my experience, for "head end" need mpeg2ts stream from professional devices.
most playout softwares give bad mpeg2ts.

also I prefer vlan/mpls and IP priorities from ISP.

my favorite encoder is EN8030 from ebay. only EN8030/(EN8090 too)
сheap price, many lic features, great work.

I have used many SW and HW with full licenses .
in my opinion "Tandberg is the best"

Of course, a good price for other equipment is also great. even old Tandberg too expensive ((
