Digital Transport Adapters (DTAs) are one-way devices that convert incoming digital signals into analog signals that can be viewed by older television sets. Most are simple "channel zappers" that do not support on-board electronic program guides nor can handle interactive applications such as video on demand (VoD). Their inherent one-way capabilities also prevent them from viewing channels delivered in a "switched" tier.

Some MSOs, most notably Comcast Corp. (Nasdaq: CMCSA, CMCSK), are using DTAs to fuel analog reclamation strategies. In the Comcast example, the MSO is migrating channels from its analog advanced basic tier to digital format. Once that occurs, analog TVs would then require a DTA (or a regular set-top box) to view those channels. (See Comcast's $1B Bandwidth Plan and Comcast Seeds Digital Shift With Free Boxes.)

Several vendors have developed DTAs for the U.S. cable market. Pace Micro Technology , Motorola Inc. (NYSE: MOT), Cisco Systems Inc. (Nasdaq: CSCO), and Thomson S.A. (NYSE: TMS; Euronext Paris: 18453) are all already on board as DTA suppliers to Comcast. Evolution Broadband LLC , meanwhile, has developed a DTA (using the Digital Video Broadcast, or DVB, platform) it's targeting to small- and mid-sized MSOs as a component of a broader all-digital video platform. (See Evolution Thinks Small .)

DTA

The DTA market has not developed without controversy. A July 2007 Federal Communications Commission (FCC) mandate prevents MSOs from deploying set-tops with integrated security, forcing most MSOs to deploy set-tops with the removable CableCARD. DTAs, at $35 to $50 per unit, are said to cost hundreds of dollars less than an entry-level, CableCARD-based set-top. (See Countdown to 'Seven-Oh-Seven'.)

In June 2009, Evolution obtained a three-year waiver to couple its DTAs with an integrated conditional access system from Conax AS . Since then, several parties have urged the FCC to rescind it on the notion that the waiver will hinder CableCARD adoption and undermine the development of a retail market for TVs and set-tops based on the tru2way platform.

Cisco, Moto, Thomson, and Pace are also seeking similar waivers at the FCC for DTAs that can activate a "latent" content protection scheme via a firmware upgrade.

The current DTA crop can display standard-definition video, but Evolution is working on a model that can feed through and display high-definition programming.

Thanks Jeff.  OK, so this is the electronic version of the push-button mechanical tuner, hard wired (no wireless) I got with my first cable TV subscription in 1983?

DTAs could be considered a low-end set-top, capable merely of converting digital video signals to analog so analog TVs can display them.  Some DTAs have IPGs and security, others don't.

...what's the difference between a DTA and a Set-Top Box?

Heh, the digital version, anyway. Maybe your '80s-era cable box looked something like this.  Or this one (one can never have enough devices with faux wood).

A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
