SW Version

LS_RM3_3.2.1 (2088)

Device class

The Lifesize Icon 600 is a full HD capable set-top system for conference rooms and meeting rooms. It belongs to the product line of the Lifesize Icon-series and covers the mid-range performence class. (see also the test report Lifesize Icon 450)

The device supports two monitors and contains two inputs for audio sources. The Lifesize Icon 600 can be controlled by a remote control or touchscreen display.

Scope of Delivery

The scope of delivery includes a 1080p60 PTZ camera, the Lifesize Phone HD as microphone, a touchscreen, a remote control and all necessary cables. The camera has a ten times optical zoom.

Protocols and bandwidths

The device connects calls through H.323 up to a bandwidth of 6000 kbps. The data transfer is realised using H.239. SIP-Calls are possible via registration at a SIP registrar.

Installation

The Lifesize Icon 600 can be put in operation just in a few minutes. All necessary components are available. The quick reference card is enclosed and supports the commissioning if required. After the device has been turned on, the network configuration can be applied by the administrator menu. Basically, the system is intended to be intergrated into the Lifesize Cloud. In the stand-alone-operation (for example within the service of DFN VideoConference) more settings have to be set up which cannot be set up directly at the device. The settings have to be configurated via web access on a clean and self-explanatory surface.

Test

Start / Power consumption

The device takes about 152 seconds after switching on the power until it maintains the operational readiness. Switching from standby mode to the operation mode takes 5 seconds. The typical annual power consumption is around 165 kWh.

Operation

Depending on the preferences, the device can be operated by the touchscreen control of the Lifesize Phone HD or by the menu control of the video output with the remote control. The handling is simply structured, clean and self-explanatory. The remote control became reduced to a mute/unmute button for the microphone and 4 directions keys with an ok-button. With this way to operate, the user is able to set up the menu and accomplish the entries - for example the configurations and calls.

Audio

The audio in tested connections was encoded with AAC-LD, AAC-LC, G.722.1C or G.722. The audio quality was rated as very good. In the connection to the Polycom Debut with the latest Software, the device did not received any audio. The connection statics shows, that the Polycom Debut Siren is using LPRRSAC as the audiocodec, while the Lifesize 600 is sending with G.722.1C. Because of this mismatch, there could not be received any audio signals.

Video

The video quality in all tested connections was rated as very good with one exception. Only the connection with the system LifeSize Team 220, the receiving video quality was just rated as good. The video compression was using the video codec H.264 without exceptions . In most of the connections the maximum possible video format 1080p was utilized, otherwise the format 720p was used.

Data presentation

During the individual test connections the video codec H.264 was used for the transmission of data presentations. The format depended on the technical possibilities of the opposite side. While the older devices ( building period until 2012 ) were also using VGA to transmit the data presentation, the newer devices were also using the format 720p and 1080p.

The quality of the sent slide presentation ( static contents ) by the Lifesize Icon 600 could be rated by the opposite side as very good. That was also the case at receiving content, only the quality of the Cisco C40 could be rated as ok. The Cisco-system C40 was sending the slide presentation with about 2800 kbps and 720p@20fps. Apparently the Lifesize Icon 600 reached the limit of perfomence at this transmission.

At the transmission of moving content ( SD- and HD-movies ) in the data channel, the resulotion and the frame rate were dynamically adapted, depending on the sent content. Depending on the data presentation the format is switching to a lower resulotion in favour of the frame rate, whereby the latter is increasing. With this possibility the system was controlling the quality parameters in favour of the data presentation. For instance, in case of the connection with the software Polycom Real Presence Desktop the content was moving between 720p@10fps and 624x352@30fps. The user cannot affect it. Unfortunately the company did not informed us in which situations the related control functions were used.

This method has acheived that all the SD- and HD-movies, which have been sent in the data channel, reached the opposite side in an applicable quality. Problems arised at the receiving point, when the opposite side was sending with a high resulotion, high frame rate with a large bandwidth (Cisco C40,Panasonic KX-VC 1600). Apart from that the practical usability was also given.

Detailed findings can be found in the compatibility matrix.

Camera remote control

The Lifesize Icon 600 could control the remote site as long as the technical requirements of the receiver were conform.

Service DFNVideoConference

The cooperation with the DFN-MCU worked very good. H.264 was utilised as video codec and as resolution were used 720p@30 fps in transmitter direction and 1080p@25 fps in receive direction. As Audio codec AACLD was utilised with 64 kbps in transmitter and 96 kbps in receive direction. At the transmission of data presentations H.264 was used with 720p.

Gatekeeper

The use of Gatekeeper GNU-GK did not cause any problems.

SIP- and URI-Dialing

Calls to the DFN-MCU are possible via SIP-dialing with the syntax "Konferenz-ID@vc.dfn.de" without registration at a SIP-Registrar are not possible. The Lifesize Icon 600 is requesting a registration at a SIP-Registrar. Calls via URI-dialing by H.323 Version 5 (formerly H.323 Annex O) are possible with the syntax "194.95.240.2##Konferenz-ID", whether the video conference device is registered at a gatekeeper or not.

Encryption

All connections were realised by H.235 with AES-128 media encryption. If necessary the encryption has to be enforced with the option [H.323 Security "strict"] on the side of the Lifesize Icon 600.

Others

The Lifesize Icon 600 offers a spam filter configuration against unwanted calls.

Conclusion

The Lifesize Icon 600 is a compact full HD capable system for medium-sized group conferences. It is convincing by an intuitive user interface, very good audio- and videoquality as well as connections with modern opposite sides also in the field of data presentation with a good practical usability. The device, which actually is intended to be used for the cloud-based video communications platform by Lifesize, works also easy in the stand alone operation. On the basis of these properties together with a pleasant price-service-ratio the device can be fully recommended.
