From the editor 06/07/2015:

The publication of the results of this test caused a wide resonance among industry professionals; test participants continued to vigorously discuss its results, drawing conclusions based on the opinions of invited independent experts. We are pleased to provide our readers with additional information on this event:

We would like to emphasize once again that AV Club, being an independent platform for holding open events for industry specialists, does not pretend to select one winner in such tests. The main tasks when creating a scenario are to identify the advantages and features of installing systems for using data in the work of design engineers, installers and other interested industry specialists. Conclusions about the championship are made directly by invited experts and are deeply subjective.

Text: Pavel Kudelin

As expected, testing was damn interesting and informative. Almost four hours of assignments, auditions, and comparisons provided such an amount of information that is akin to a full-fledged training with practice. The testing scenario was fully implemented, and at the end the experts noted that “they wanted more tasks.” This, of course, speaks of a dense and eventful event.

When the script was created, we set out to analyze the multimedia capabilities of the systems and functionality for working with documents. The testing does not include tasks for voting and simultaneous translation, but in fairness, we note that this is for another four hours. And we will be happy to take these tasks into the next test.

TECHNICAL SUPPORT OF TESTING

Let us explain a little what the technical side of testing looked like.

Three conference systems (Bosch, Taiden, Televic) were presented in sets of a chairman and two delegate consoles. The systems were connected with a balanced signal to the Symetrix audio platform, from which, without processing, audio was output via the aes/ebu digital interface to the Fohhn amplifier and acoustics.

Each manufacturer has its own technology television cameras. Bosch and Taiden have “native” cameras; Televic does not offer cameras, so during testing a circuit from an integrator was implemented.

Special thanks to Bryullov Consulting for technical assistance in organizing testing and providing additional equipment.

EQUIPMENT DESIGN

In the first stage, we invited experts to evaluate the industrial design of the remote controls. This includes the quality of the screen, the ergonomics of the menu, the quality of the buttons, and the ergonomics of the remote control. Considering that the manufacturers mentioned the ability to perform at the console while standing, I was also interested in how convenient it was.

Bosch: the external design was noted by all experts. The remotes are really beautiful. In this case, the screen is located at an angle that provokes glare. The reflection of ceiling lights is also noticeable when working with the remote control while standing.

Taiden: Many experts noted that the size of the remote controls is too large for many tasks. We can agree with this, given that due to this, users have a truly large screen for working with documents. The interface is ambiguous, but for many customers, it may, oddly enough, be closer and clearer.

Televic: Many were confused by the exclusively mortise format of the remote controls. Otherwise, the screen is of good quality, the internal menu structure seemed incomprehensible to one group and very pleasant to another. The remote control itself is wide. This means that during installation it is necessary to design a significant area for the delegate’s workplace.

Each system has its own concept of working with documents. Despite the fact that all remote controls have Android installed as a system, the functionality is extremely different.

Let's try to formulate first the differences between the concepts of working with documents.

• The possibility or impossibility of installing third-party applications on the remote control operating system. For example, for integration with external systems;
• Possibility or impossibility of downloading documents from the delegate’s workplace;
• Work with many different file formats or are significantly limited by them.

And now for each of the manufacturers:

The WEB server is deployed on a separate server. It creates pages for downloading and storing files. The pages, of course, are created in the desired design, and the web server itself can be either flat HTML files or an internal site on a CMS system or document management system with access via HTTP. The desired page is displayed in the remote control. The page downloads the file and then opens it with the default application in Android on this remote control.

In theory, this means you can change default applications, develop applications for your own file types, and implement other features.

You can forcefully distribute the file to all remote controls.

Important: It was not possible to get a clear answer whether this method is the main one from the manufacturer or whether it is an implementation of working with files from the Hi Tech Media company, which acted on behalf of the manufacturer.

Pros	Cons
The ability to create any interface, displaying pages from a web server. The ability to work with any type of files if you have the appropriate application for viewing them on the remote control.	Additional task of organizing IT infrastructure (web server), page design. Access control to files is implemented not at the conference system level, but using web server tools.
Uploading files is possible both through the operator and by the user, provided that you have upload rights to the web server and the appropriate interface. Whether this is a plus or a minus is up to you to decide.

The system has a server on which documents are stored. Documents are uploaded to a single file archive. This is a folder with a flat structure that can be accessed over the network. Access to the folder can be given to users, or it can be left only to the operator. Plus, the remotes have a built-in USB port through which you can connect flash drives, downloading files directly to the same shared storage. The rights to download files via USB can be configured for a specific remote control.

To view a file, you need to use the remote control to go to the menu section for working with files. There you need to download the file to the remote control (locally) and then open it.

External applications cannot be installed on the remote control. You can forcefully distribute the file to all remote controls.

Only PDF format is supported. This is done for security reasons. The operator uploads the PDF file prepared in advance into the system. The file can be associated with a specific event, part of an event, or be publicly available. After downloading through the operator software, the file, if the user has rights, can be displayed.

External applications cannot be installed on the remote control. You can forcefully distribute the file to all remote controls. There are extensive settings for working with the file. For example, you can allow users to move around the presentation while it is being presented, or prevent users from leaving the current slide.

MICROPHONE QUALITY

Despite all the multimedia capabilities of conference systems, it would be strange to bypass the sound quality test. We didn't get around this characteristic by conducting blind testing of the microphones. Bosch and Taiden microphone consoles come with two microphone options: a classic gooseneck microphone and an array microphone. Testing was carried out on one remote control from each manufacturer. But what type of remote control it would be, with what type of microphone, was chosen by the manufacturer himself.

Two people (a man and a woman) read the same text. Half of the text was read while sitting at a close distance from the microphone, the second half while standing.

WORKING WITH DOCUMENTS

When the documents were loaded, we offered to work with them, testing the convenience of the interface, the ease of using the screen to work with materials.

I agree with a number of experts who said that the interface is very different from the usual way of working with documents on mobile devices. And perhaps it would be easier for participants if the model was recognizable.

And here are the results:

Read the experts' comments. They clearly show how clear the interface is for some, and how completely confusing it is for others.

WORKING WITH TECHNOLOGICAL TELEVISION

We use our own HD cameras, which output an IP stream to the camera and a digital SDI signal to the switching system. With your cameras, basic settings are very quick and easy. Control by presets that are stored in the camera. In case of complex tasks (the need to register a camera track, for example), it is necessary to use external control systems, since the basic functionality does not have such an option. But the speed of connection and setup is really pleasing.

Likewise – your own cameras, working with presets. Presets for each workplace + general plan. For basic capabilities it is quite enough.

The manufacturer does not offer its own cameras, so a combination is required: camera + central unit + control system. During testing, the Bryullov Consulting company showed its own solution based on Cue System control systems controlled from a tablet. I would like to note that the solution itself is very functional, but it presupposes that the customer or integrator has the necessary competencies in the field of system integration.

One way or another, all three systems have an open interface for interaction with external systems and, if you have a full-time programmer, creating a connection with technological television will not create problems.

VIDEO DISPLAY

The systems have the ability to broadcast an external signal. At this stage, we decided to test how well the video stream broadcast over IP would be displayed on the remote control. To do this, we connected a laptop with a video (1080p) via HDMI to all systems and displayed a control signal on the display.

The following points caught my eye:

Bosch– the signal disintegrated, strong braking and signal sticking were visible. The quality is unacceptable for the work process. Severe color distortions too. The likely reason is that the central unit does not have a built-in encoder in the IP and the encoding was carried out by third party applications (not Bosch) that simply could not provide the required quality.

Taiden– you can adjust the signal encoding quality depending on the required bandwidth. We looked at the encoding quality at 768 Kbps – pixelation is visible, especially considering the large screen in the remote control. Then we set the stream to 2000 Kbps - everything was fine. Some encoding delay is visible. The picture on the remote control lags behind the reference picture on the display.

Televic- perfect! The delay is not visible at all, the quality is excellent. A manufacturer's representative present in the hall said that this is the company's know-how in terms of optimizing encoding on the H.264 codec.

GENERAL CONCLUSIONS

My personal impressions from testing coincide with the experts’ assessments. I would like to add this:

• The user interface can and should be made more intuitive. But this is the first sign in the field of multimedia conference systems, so there is no doubt that this will happen.
• The functionality/security dilemma is handled differently by each manufacturer. Bosch has the ability to install its own applications (integration with video conferencing from TrueConf was demonstrated). Taiden allows you to connect flash drives locally. But Televic insists that it is unsafe.

Time will tell who is right and where the golden mean is.

THIS IS HOW IT WAS...
