Digital Rapids TouchStream

Digital Rapids TouchStream

Long gone are the days when only the largest companies, churches, and universities could afford to get video and sound out to the world. All of these entities have a need to get the word out, but with the emergence of small, portable web-streaming appliances has come what some have called a democratization of information. Using the Internet as a worldwide broadcast network, even individuals can become global broadcasters or narrow¬casters, and this has had a profound effect on both content producers and viewers. Let’s have a look at some of the current offerings in this dynamic market.

Billed as an appliance that turns any room into a webcast studio, the Accordent Capture Station includes video and VGA capture cards to input all the various elements consisting of audio, video, and graphics and seamlessly synchronizes them into one complete presentation. Laptops, projectors, smartboards, and document cameras can be connected to the unit. The user simply clicks Start, and the system will capture, record, and synchronize all the presentation sources. The resulting combined file can be streamed live to the Internet or an intranet, and it can be recorded and posted for viewing on demand. Pre-installed editing software enables the user to review and edit each element of the presentation including adding or cutting images and adjusting presentation timing. Viewers can receive the presentations with Windows Media Player, RealPlayer, MP3 players, and a range of browsers.

For simplicity, portability, and ease of use, the Webcast in a Box from Box Populi is hard to beat. The device allows the user to encode and stream a combined file consisting of video from a camera and video from a computer display. Beyond that, the background may be customized with a specific color, image, banner, or logo and viewed with RealPlayer. The hardware has composite and S-Video jacks for video input, and the network connection is labeled “1GB.” It can interface at network bit rates of 1Gbps, 100Mbps, and 10Mbps. The device can be operated by simply plugging in a USB key to start the webcast and removing it to stop the presentation. The unit displays its IP address in the LCD window on the front panel. Anyone with a browser on the same network just types that IP address into the URL window of the browser to view the webcast.

An integrated component of the Cisco Digital Media System (DMS), the Cisco Digital Media Encoder 1000 provides live and on-demand digital streaming media with video and sound on any IP network, and it can also be used as a standalone unit. The front-panel buttons allow users to select between a number of predesignated Windows Media and MPEG4/H.264 encoding profiles. On-demand formats supported include these and Flash. The unit’s physical interfaces include both composite and S-Video connections along with RCA and XLR connections for audio. There is also a front-panel dock for downloading directly to an Apple iPod. The Cisco Digital Media Manager can set up and control multiple media encoders such as the Media Encoder 1000, schedule live streaming events, and publish live and on-demand streaming presentations.

The Webcaster-3 from Communitek Video Systems is packaged in a tough road rack, and it includes every¬thing needed to input audio and video signals and output an IP network signal in up to three simultaneous streams, depending on which build option is selected at purchase. While performing live streaming, the unit can simultaneously record an archive file to the internal hard drive for on-demand viewing as well as onto an onboard DVD recorder as a removable backup. Synchronized PowerPoint presentations can be assembled using third-party PowerPoint push software such as sofTV.net or Encoder Script. The unit can be connected to a small video switcher for mobile webcast production.

Sending video to the Web has become push-button easy.




The incredibly simple front-panel layout of the new TouchStream web-streaming appliance from Digital Rapids belies its operational versatility in an easy-to-deploy form factor. The unit uses the same video-preprocessing capability as the other streaming encoders from Digital Rapids including advanced de-interlacing with pixel-level motion adaptation, scaling, and filtering. Low-light situations generating noise in the video are countered by the TouchStream’s 2D and 3D video-noise-reduction features. Dynamic range compression/expansion in the audio preprocessing assures smooth sound levels, and there is a graphic overlay feature that provides the option of using a superimposed logo or other branding graphic to the outgoing stream. Formats include AVC/H.264 for Adobe Flash Player 9, VC-1 for Windows Media Player, On2 Technologies VP6, 3GPP, and MPEG-2. The front panel includes both a video monitor and an audio-level meter.

Primarily designed for the IPTV market with multiple MPEG-2 channel capability, the rackmounted 4 Caster C4 from Envivio can include optional encoding capability for picture-in-picture, 3G mobile TV applications, and Internet video streaming in resolutions up to VGA. For Internet applications, the unit can provide content for playback with Windows Media Player, Apple QuickTime Player, and the VideoLAN VLC player with up to four standard-definition inputs. Also included are IP inputs and outputs to reduce video head-end cost and complexity. Options also include an analog or digital video and audio inputs interface. Reliability is enhanced with dual hot-swappable power supplies and redundant Ethernet interfaces. A web-based user interface provides built-in control and monitoring, and Simple Network Management Protocol Management Information Base (SNMP MIB) allows monitoring by an external network-management system. The unit includes a pass-through for audio, program and system information, and encapsulated data.

Fully compatible with HaiVision’s haiPlay and QuickTime players, the HaiVision Oscar H.264/MPEG-4 AVC encoder/decoder can deliver DVD-quality video at up to 1.5Mbps to storage servers or for distribution in an IPTV, QuickTime, or podcast environment. The unit can input composite or S-Video and stereo sound in a fanless chassis, and three units can be mounted in one rack space. The rear panel includes LED indicators along with connectors for serial and IP interfaces, 3.5mm stereo audio input, composite, and S-Video inputs, as well as 12VDC power connection. Last year, the company announced direct compatibility between the Oscar encoder/decoder and the Wowza Media Server Pro platform for live Flash H.264 content delivery. Oscar is targeted for streaming live Flash content from remote events or on campuses where many classrooms could need live delivery in a standard Flash environment.

Inlet Technologies Spinnaker 7000

Inlet Technologies Spinnaker 7000

The new Spinnaker 7000 from Inlet Technologies provides live HD streaming and H.264 over broadband networks with HD streams at up to 720p resolution in either VC-1, H.264, or Flash VP6. Through BNC connections, the inputs can accept 1080p, 1080i, and 720p over HD-SDI (SMPTE 259M) and standard-definition formats with embedded stereo sound, or it can input audio through XLR connectors or an AES audio input. The unit also streams in multiple formats simultaneously; supports Flash cue points for VP6 and H.264; includes scheduling for one-time or recurring events; and supports closed captioning, open captioning, and inserting metadata into the video stream. The Spinnaker 7000 can be set up and operated from the controls on the front panel or managed remotely through a web interface or SNMP. Various technical parameters are grouped into setups that can be selected for simple and quick configuration.

Kulabyte of San Markos, Texas, offers the XStreamCast Nomad as a small, transportable, carry-on unit for streaming HD/SD video using the AJA Xena LHe I/O capture card with a single input and output and webcasting to viewers using Adobe Flash Player 9 or 10. The unit can encode video at up to 720p at remarkably low bandwidth, and it is compatible with Adobe Flash Media Server 3.5; Wowza Media Server Pro; and Akamai, Limelight, Mogulus, Edgecast, CDNetworks, and other qualified content-delivery networks. The unit can also accept 2-channel AES audio, SMPTE 259-embedded audio, and analog stereo. The XStreamCast products come with the company’s XStream Live software preloaded and fully configured with a graphical user interface for customizing encoding parameters. All the user needs to do is configure the Real Time Messaging Protocol (RTMP) publishing point and click Encode.
