Abstract: The invention discloses a method and a device for realizing Digital Video Recorder (DVR) data decoding playback. The method comprises the following steps of: configuring a coding channel for generating a decoding playback signal source, and allocating a corresponding memory space for the decoding channel; respectively receiving each original data information output by each coding processing chip,and forming the decoding playback signal source in the memory space according to each original data information; feeding the decoding playback signal source into the coding channel for compression coding; and performing the decoding playback on data information generated after the compression coding in the coding channel through a decoding channel in a decoding processing chip. On the premise of not adding hardware cost and not influencing a decoding display frame rate, the decoding playback of multi-loop coding data is effectively realized.
