What is DDB?
Digital direct broadcast, or DDB, is a TV operating system that allows television sets enabled with it to perform multiple functions. This includes direct digital transmission, 3D viewing, internet browsing and cloud computing. The major advantage is the elimination of a set-top-box.
This technology works best over direct-to-home (DTH). DDB-enabled TVs receive digital signals directly from the dish antenna and broadcast it. Audio and video quality is also better than current cable and DTH transmission.
Videocon and Philips are working on the same technology.
Videocon and Philips are ready to launch new models that can receive and broadcast TV signals without a set-top box.
Philips will launch its TVs by next month.
The price differece between new LEDs and regular ones will be Rs 2,000 to Rs 3,000. For instance, a 42-inch new LED from Philips will cost Rs 65,000, while a regular one from the company is available for Rs 63,000.
The technology that will enable Videocon and Philips to launch these new LEDs is called digital direct broadcast (DDB). DDB is a TV operating system that allows TV sets compliant with it to perform multiple functions.
Besides direct digital transmission, DDB-compliant TVs allow 3D viewing, internet browsing and cloud computing. Cloud computing, here refers to computing and storage capacity over a network. End-users access cloud-based applications through a web browser, while the business software and data are stored on servers at a remote location. For cloud computing, an internet connection is a must, which DDB-compliant TVs are able to provide.
But there are disadvantages too, DDB works best on the direct-to-home (DTH) platform, not on the cable. But the major portion of TV viewing homes continues to use cable, not DTH, the new TVs will not constitute a major portion of the flat-panel TV market, at least for the time being.
Videocon, will bundle its DTH service as a package with the new TVs for those consumers who do not have a DTH connection. Philips has tied up with Videocon as its DTH partner.
