Law Firm Turns to Haivision for Enterprise Video Streaming to Mobile Devices

In order to continue the law firm’s standard of excellence, Weil, Gotshal & Manges adopts cutting-edge technologies to ensure its attorneys communicate efficiently and have the best access to continuing education. Weil’s New York City headquarters features a large boardroom where corporate meetings and continuing legal education sessions are held daily. The room accommodates more than 65 people, and attendees sitting in the back of the room are more than 70 feet away from the presenter and presentation display screen.

The room’s large size became increasingly distracting for presenters and audience members, who had to constantly turn in their seats to view the presenter and projector screen located at the front of the room. Law firm executives wanted the boardroom to feel more intimate, while optimizing meeting interactivity and minimizing distractions. They needed a solution whereby all attendees would be able to see the presentation slides regardless of where they were seated.


The firm wanted a solution capable of streaming presentation content directly to an iPad in the hands of each meeting attendee in the room. While investigating solution options, Weil found many applications that could stream from an iPad to a projector, but they could not find a solution that would stream from the main presentation screen directly to the tablets. Weil turned to systems integrator Video Corp. of America (VCA) to implement an enterprise communications system for the executive boardroom.

Partnering with video technology provider Haivision and visual display solution provider Primeview, VCA created an integrated system that could synchronize the presentation slides from the presenter’s laptop to a Primeview video wall and iPads in the boardroom. VCA implemented Primeview’s premium visual display solutions, including a virtually seamless plasma video wall with an anti-reflective surface and high brightness and contrast to capture the audience’s attention.

Using Haivision Makito HD encoders, which support up to 1080p60 resolution with low end-to-end latency, and InStream Mobile players running on the tablets, the presenter’s content can be viewed simultaneously on the iPads and video wall. The system ensures that when the presenter clicks through to the next slide, that same slide appears on the iPads and video wall with virtually no delay.

The source—a laptop running the Microsoft PowerPoint content—is connected to Haivision’s Makito DVI encoder, which sends a multicast transport stream using forward error correction (FEC), controlling any errors in the transmission over the wireless network. That stream is then sent to two Aruba Networks wireless access points, from which the iPads receive the content and play the stream via Haivision’s InStream Mobile players.

InStream Mobile is designed to bring high quality, low latency HD video to iPads, iPhones and Android devices, with playback of unicast and multicast video. InStream Mobile takes advantage of transport stream multicast to deliver the highest performance media experience to many simultaneous mobile viewers throughout a facility or campus without a dedicated streaming server and also supports HLS streams for Internet sources.


With presentations readily accessible on their iPads, Weil attorneys benefit from a state-of-the art boardroom that is inclusive in design with technology that is unobtrusive and does not disrupt the main focus in the room. Leveraging low-latency streaming to mobile devices, Weil attorneys can collaborate and communicate more effectively in corporate meetings, and continuing legal education sessions and are no longer impeded by participants not being able to see presentation content up close.
