RTD2986IK
GENERAL DESCRIPTION
RTD2986IK is a highly integrated TV SOC solution for ATSC digital television platform. Integrating latest
advanced technologies from REALTEK Semiconductor, the world leading TV SOC provider in TV industry,
RTD2986IK provides the most cost-efficient solution for multimedia TV application with creative and attractive
features exclusively presented.
In order to achieve the lowest BOM cost in a multi-media TV platform, RTD2986IK integrates DTV, ATSC/QAM
demodulator, TV/multi-media all-purpose AV decoder, VIF demodulator, and advanced Sound/Video
processors into a single device. This not only reduces the overall BOM significantly, but also facilitates the
design of originally-complicated TV systems for developers. In addition, the memory-embedded solution
provided by RTD2986IK can reduce the excessive work of memory interface routing on board and the risk of
memory performance degradation while powering cost-down in the total system.
The powerful multimedia A/V decoder inside RTD2986IK is hosted with a dedicated hardware video code
engine to secure fast and stable video streaming playback. Moreover, RTD2986IK is equipped with a DSP
specifically Designated for audio application, including digital audio format decoding and advanced sound
effects and a high performance RISC CPU to manipulate all possible routines and house-keeping activities.
With extendable USB 2.0 interface, an RTD2986IK based system can turn into a high quality media-center in a
simple manner. RTD2986IK enables feature rich products that bring differentiation to the iDTV market. By the
use of powerful CPU/GPU and AV decoders capable of decoding a plethora of high definition content from
Ethernet.
RTD2986IK supports the latest MHL technology, which allows user to stream audio and full HD video from
mobile devices to televisions. Power management and low-power design of RTD2986IK makes it possible to
charge MHL devices even in standby mode. The MHL/HDMI dual-purpose port on RTD2986IK will enable
charging if MHL devices are automatically detected.
For standard users, the RTD2986IK provides multi-standard analog TV support with adaptive 3D video
decoding and VBI data extraction. The built-in audio decoder is capable of decoding FM, AM, A2, BTSC and
EIA-J sound standards. RTD2986IK also supplies all the necessary A/V inputs and outputs to complete a
receiver design including HDMI receivers and component video ADCs. All input selection multiplexers for video
and audio are integrated, including full SCART support with CVBS output. The equipped color engine is the
latest masterpiece of REALTEK technologies, providing excellent video and picture quality in Full-HD and
large-scale display system. RTD2986IK also supports an ultra low power standby mode to meet the latest
energy legislative requirements without any additional hardware.
