Sharing content in Windows 8 and later

Vidyo introduced a change in a recent VidyoDesktop release (3.6.5) that changes the way you can share content from VidyoDesktop running on Windows 8 and later.

This is from the technical bulletin from Vidyo:

On Windows 8 and later, in certain scenarios when a user shares an application, other applications running on that user’s machine may also be shared into the conference. Due to this privacy concern, we have limited sharing on Windows 8 and later to sharing the full display only. On Windows versions earlier than Windows 8 and on Mac OS X, this issue does not exist, therefore application sharing is still available.

We have not seen this behaviour ourselves, but it is clear that this is not a scenario that you would want to have happen when you are sharing content.

If you share content from a Windows 8 device with a single screen, you will be sharing the same screen that VidyoDesktop is running on. When you start sharing, you will see VidyoDesktop minimise itself to a small window at the bottom of your screen. If you have two screens, then you can share the screen on which VidyoDesktop is not running and VidyoDesktop should not minimise itself as it does with a one screen setup.

 

Full HD Recording and Streaming now available on Vidyo

We have just completed a major update to the TENET Vidyo backend. Vidyo have pushed out new releases of the software that runs the VidyoPortal, VidyoRouters, VidyoGateways and VidyoReplay.

End users will not notice many changes, as these are mostly updates to the underlying server architectures. However, Tenant Admins and Operators in the universities and other organisations using this service will notice a change in the admin interface, and all users will benefit form a couple of very welcome enhancements in capability.

Changes to /admin interface

Vidyo have redone the Admin and SuperAdmin interfaces to move away from the old Flash based interface to a more modern HTML5 style et up. All the old functionality is still there, albeit sometimes in slightly different places.

Gateway Capacity

One welcome result of this upgrade is that the capacity of the VidyoGateway Cluster that we are running is magically doubled! I think that owing to a move to a full 64 bit architecture, Vidyo have been able to squeeze more connections out of a given Virtual Machine set up. We need to do some rearrangement of things, but we hope to be able to offer a decent size pool of of full HD H.323/SIP connection. Don’t forget that you can use the Gateways as a cloud VMR, without Vidyo – see this page for information.

Full HD Record/Replay/Streaming

This is really good news. Up to now we have been restricted in our recording, etc. , to HD (720p). That’s OK, but with the continued adoption of high resolution screens displays, the lack of Full HD was starting to show. We have now enabled Full HD recording – see the page on recording a meeting for instructions on how to start a recording. We have enabled three new recording profiles:

  • Full HD People & Content
    • Shows shared content (if present) with the people in small windows to right and below content
  • Full HD People – No Content
    • Just People – no content (even if shared)
  • Full HD Content Preferred
    • Shows just content if it is being shared.

New VidyoRemote App for iPad, and other updates

Vidyo have announced the release of some new versions for the Vidyo badged Room systems and also the VidyoRoom SE version. This is in addition to a welcome updating of the VidyoDesktop for Linux to match the versions already available for MacOS and Windows. Finally, there is a new VidyoRemote for iPad that looks very nice.

Some highlights of the new VidyoRoom releases are:

  • New side-by-side option for VidyRoom SE that allows one screen to show VidyoRoom and the other to show the Windows Desktop. You must be running VidyoRoom SE as an HD230 to be able to so this
  • It seems you can now uninstall and the re-install VidyoRoom SE and choose a different version to run as (previously it was a one way choice).
  • New USB 3 cameras supported:
    • The Mimray UV950 is a USB 3 Camera with 12x optical zoom, and up to 1080p at 60fps
    • The Sony SRG-120DU USB 3 camera with 12x optical zoom and 71 degree wide angle
  • Improved quality of audio played back through an INOGENIE content capture device

VidyoRemote 3 for iPad

This looks really nice. It essentially gives you a touch screen version of both the IR Remote and the Control Meeting Web GUI rolled into one. You pair it to the Room system – you will find the pairing code for the VidyoRoom system on the backend web GUI for the Room system (get to that browsing to the VidyoRoom system IP address and authenticating). Once paired, you choose which room system (if you have set up a number of different ones) and away you go with full control. See the screenshots below. Get it from the iOS App Store.

No word on whether they are developing an Android Tablet version.

Sharing a PowerPoint presentation in a Vidyo Meeting

One of the great things about Vidyo is the ease of sharing content from VidyoDesktop – just click the sharing button on the toolbar, and select the the open window or screen you want to share. Then all the participants in the meeting will see the share unless they choose not to.

That’s great until you try to share PowerPoint presentations! In the default set up of PowerPoint,  starting the slide show means the presentation takes over the whole screen(s). That means you can’t go back to Vidyo to start sharing.

The way round is to change the way that PowerPoint makes the presentation available. In the Menu bar (MacOS) or Ribbon Tabs (Windows) select Slide Show and then the option “Set Up (Slide) Show“. In the dialogue box  that appears elect “Browsed by an individual” radio button under the Show type list.

When you go to run the Slide Show again, you will find it is running a proper OS window that Vidyo has no trouble sharing, and from which you can switch to-and-fro with Vidyo.

Preparing for and running a large event with Vidyo

TENET recently helped our friends at North-West University (NWU) to put on a large event on the subject of computational and digital capacity building among researchers and research support staff with overseas speakers and many participants across a range of institutions in South Africa. Following the meeting, we have pulled together these pointers to help you if you are thinking of doing something similar.

Before the event

Here are some of the key things to do before your event:

  • Start your planning in plenty of time.
  • Send an email to vidyo@tenet.ac.za with an outline of your event and the people you want to connect up.
  • Reach out to your IT and videoconferencing support people at your institution and involve them early on in the planning of the event
    • One issue to check early on is that the relevant firewall ports have been opened at the participating institutions – see this page to see what needs to be done
  • Think through the sort of event you are intending to hold. Is this going to be a webinar type event with speakers mostly imparting information with maybe a Q&A to finish, or more of a workshop or discussion with the emphasis on debate and sharing ideas? Or a training event with instructor led sessions and more engagement from the students?
  • Brief your remote speakers – make sure that they have a device that they can use to join the meeting and that they have tested it in the setting in which they will use it on the day in good time
  • Check out your venues – how will you display video and play audio and allow interaction at venues where groups of people will gather?  You may need roving mics if you want an interactive Q&A type session, and are in a big venue
  • Schedule a test session – ideally you want everyone to be in the same place and using the same equipment as they will use on the day. Run through the programme and write down a running order and a cue list listing who will speak when, and what needs to happen (presentations, a movie, etc)
  • Get your speakers to submit copies of their presentations in advance – store these in a shared area on GoogleDrive or Dropbox, etc. Fumbling for these in email attachments when they are needed is not recommended!
  • Set up a WhatsApp group for the lead people at each site and technical support people to enable communication when all else fails.
  • Send out a meeting invitation from VidyoDesktop to all participants. Makes sure you set a Moderator PIN on the meeting room your re using, as this will enable others to control the meeting, if needed.
  • Have a back up plan to connect in the event of a connection failure – a 3G Dongle of smart phone set up as a hotspot. Test these beforehand

During the event

  • Get people to check in and say hello from the remote sites – allow time in the programme for this. This will also be an opportunity to test sound levels for a later Q&A if that is what is planned
  • Have a second back-up chair for the meeting at a remote location who can take over running the meeting if the main site goes off-line. The back-up chair needs to be logged into Vidyo on the same Tenant as the main chair to be able to access the control meeting interface
  • Consider using “Presenter Mode” in Vidyo – this mutes all except the speaker’s video and audio
  • If using the Mute option in the Manage Meeting screen, use soft rather than hard mute for preference
  • Inform participants that the meeting will be recorded (if applicable) and ask those who do not want to be in camera or be heard to get out of shot or mute their video and audio
  • Turn off the option to have sounds play when people enter and leave the meeting room

See other pages on this site for access to documentation on running meetings in Vidyo

After the event

  • Send feedback to TENET detailing the good, the bad and the ugly about the experience
  • Send an evaluation form to your participants asking them for their views
  • Write up your experiences in a blog post or similar
  • Download the recording from the VidyoReplay server and make it available as appropriate

North-West University is collaborating with other organisations like UCT, Software & Data Carpentry, RDA & CODATA to offer a series of activities to better equip researchers to handle the data that their work generates. See:

Polycom no video showing fix

We had a call today from the University of Pretoria who are experimenting with interfacing Vidyo with their existing Polycom estate. This is one of the really nice thing about Vidyo – the way that you can just use it as high quality and easy to use desktop client for your existing videoconferencing activities.

They called because while they were able to connect a call from Polycom to Vidyo and vice versa, they were unable to see or transmit video. This happened on a point to point call and if they tried calling through the IVR to join a Vidyo meeting room.

The fix turned out to be quite straightforward. The Polycom unit is a Polycom Vsx7000, and on that unit, and maybe other H.323 CODECs there is a setting to support ISDN using H.261 – or Basic mode. You can access the setting for the unit through the admin interface under

System > Admin Settings > Network > Call Preference

Deselect that and restart the unit and video will be received and sent as expected.

Don’t forget that you can use your existing H.232/SIP (Polycom, etc.) endpoints to connect to meetings with Vidyo desktop, etc. See this page for instructions. In fact, you can use the VidyoGateway as a pure H.323/SIP Bridge if you really want to, although to manage the meeting, it is usually  good idea to have at least on VidyoDesktop endpoint in the meeting as well.

Hope that helps.

Vidyo for Mathematics and Statistics

One of the initiatives that TENET is working on is to develop an infrastructure to help support initiatives to improve the academic prospects and performance of mathematics and statistics faculty in some of the less advantaged universities in South Africa.

A major issue facing some South African universities is the low level of attainment of many of their mathematics and statistics faculty members. Because the opportunities for further post-graduate study were not available, and the institutions themselves lack a sufficient pool of expertise in the various branches of mathematics and statistics, many of these people have no realistic way  to improve their knowledge and understanding of their subject area.

This is a recognised problem in other countries, with even much better resourced universities in the UK struggling to provide enough expertise to span the whole range of mathematical and statistical specialisms. To overcome this deficit, two networks for post-graduate education and collaboration on mathematics have been established, one in Scotland (SMSTC) and one in England and Wales (MAGIC) (there are also two parallel networks for Physics). The reviews of these networks (MAGIC & SMSTC) have been published and show the ways in which they were set up and their governance and academic quality assurance structures and the evaluation of their performance. The way these networks run provides some useful guidance when attempting something along these lines elsewhere.

The National Department of Science and Technology (DST) and the National Research Foundation (NRF) have established a Centre of Excellence in Mathematics and Statistics (CoE-MASS) in South Africa with its base of operations at the University of the Witwatersrand in Johannesburg. The aims of the CoE are:

  • Promote knowledge and human capital development in areas of strategic importance to South Africa
  • Promote collaborative research
  • Promote and develop interdisciplinary research
  • Systematically develop a creative research training environment that is internationally competitive
  • Strive for the highest standards of quality, international competitiveness and esteem of their science, and
  • Diffuse knowledge to where it is needed.

The trolleys are a cost effective way to enable these institutions to join in with some f these activities. As they are movable, they can be wheeled between office locations and classrooms or larger venues. This will support many different scenarios of use:

  • Participation in seminars and guest lectures
  • Participation on formal teaching programmes
  • Supjrsvion meetings between Doctoral and Masters students with remote supervisors
  • Creation of peer networks of post-grad students and faculty
  • Outreach to schools and colleges
  • Interviewing prospective staff and students

To give a sens elf the trolleys  – they look like this:

The setup comprises:

  1. Trolley for single 55 inch screen
  2. 55 inch screen (HiSense)
  3. Intel NUC i5 with Windows 7
  4. VidyoRoom SE licence
  5. Logitech CC3000e camera and audio device
  6. Cables, connectors, etc

Guide price for this (which includes a PC and a VidyoRoom SE licence) is around ZAR75,000, although this price is however dependent on the Rand/$ rate.
