bitcontrol® Audio/Video Decoder

bitcontrol® Audio/Video Decoder

bitcontrol® Audio/Video Decoder is a part of bitcontrol® Multimedia Suite. It is a multifunctional multiformat decoder for different multimedia formats, e.g. MPEG-2, H.263, MPEG-4, H.264/AVC, and others (see specification).


The decoder provides a decoded image sequence in a defined chroma format for displaying on the screen. Also, the output signal can be transcoded or otherwise processed.

Application

bitcontrol® Audio Video Decoder is used as a component in programs such as bitcontrol® Simple Player, in bitcontrol® Video Streaming Server, in the Recorder plug-in and in other Windows Media® applications for the decoding of compressed video and audio.  The decoder supports DVB-TV, media files, WebCams, video streaming and other input types, depending on the connected front end demultiplexer. The decoder is optimally tuned for interacting with bitcontrol® Digital TV Link.

Functionality

bitcontrol® Audio/Video Decoder is a loadable COM object under Windows, not a stand-alone program.  Usually, a multimedia application loads bitcontrol® Audio/Video Decoder automatically, so the user does not need to take care of anything.


bitcontrol® Audio/Video Decoder operates as a software decoder for different codecs in accordance with its specification, in addition it supports DirectX® Video Acceleration - DXVA. High definition TV HDTV with 1080i definition can be played with DXVA on Celeron <1GHz and with common atom processors.


bitcontrol® Audio/Video Decoder is delivered with a separate configuration menu, making it easy and convienent to set the supported codecs and their parameters.

Furthermore, bitcontrol® Audio/Video Decoder has a plug-in architecture and the loadable plug-ins provide additional functionalities, e.g. statistic information, a systray icon for configuration during run time and others. You can find the detailed information in the documentation.


bitcontrol® Audio/Video Decoder is very robust against errors, e.g. input stream drop outs,  bit errors and other signal errors. This means the decoder is very good for DVB-T, DVB-S and Internet streaming applications.


bitcontrol® Audio/Video Decoder stands out becasue of its extraordinary color brilliance. It is based on 4:2:2 color upsampling and on exact color spreading during decoding for MPEG-2.


bitcontrol® Audio/Video Decoder can decode the MPEG video bitstream of the most important profiles and all levels of different Chroma formats in real-time, e.g. the common MPEG-2 Main Profile@Main Level. The decoder is compatible with common video standards.

Limitation: Soft decoding variant for H.264/AVC without DXVA 2.0 is not yet realtime-capable in bcAVDec Version 4.0 for HDTV.

bitcontrol® Audio/Video Decoder supports audio formats LPCM (partial) and MPEG-1 Layer 1/2. AAC is in prep.
