Abstract

The invention relates to a device for decoding an analog video and converting interlaced into non-interlaced for motion adaptive resource sharing, which comprises a video input preprocessing unit, a component video/composite video/S-video signal synchronization module, a component video/composite video/S-video signal line-field delay line set, a two-dimensional/three-dimensional dynamic noise reduction unit, a video content adaptive motion detector, a memory module and a corresponding read-write controller, a two-dimensional adaptive comb filter unit, a content/motion quantity adaptive three-dimensional comb filter and a chroma demodulation unit, a P1 field oblique angle interpolation module, and a motion adaptive interlaced to non-interlaced unit. The device not only can ensure the high-degree detail and the fidelity of motion images, but also can ensure the complete chroma separation of still images; besides, the device can perform convenient and independent configuration on each module.

Description

technical field [0001] The invention relates to an analog video decoding and interlaced-to-progressive device for motion adaptive resource sharing, especially a motion adaptive resource suitable for feature analysis based on video time domain and space domain in equipment such as television receivers and video playback Shared analog video decoding and interlaced-to-progressive conversion. Background technique [0002] In the traditional sense, the analog composite video signal modulates the chrominance information and superimposes it on the luminance channel for propagation / broadcasting, and due to the limitation of channel bandwidth allocation in the early stage of television technology development, the video signal is interlaced (60 or 50 Hz field frequency) for transmission, and the receiving end performs bright color separation through filtering and other processing. For example, the TV receivers we currently use are mainly used for this processing, and need to convert i...
