CompressionMPEG-2 encoder (5)To meet the requirements of different image quality, storage capacity, and bandwidth.For end users, due to the resolution restrictions of the existing TV, the high-definition picture quality (such as DVD picture) brought by the MPEG-2 on the TV is not obvious, to its audio characteristics

FFDShow can be called an all-powerful decoding and encoder. at first, FFDShow was only an mpeg Video Decoder, but now he can do more than that. the video formats that can be decoded are far beyond the mepg4 range, including indeo video, WMV, and mpeg2. at the same time, it also provides a variety of processing options, you can sharpen the screen, adjust the brightness of the screen and so on. more than vide

. This reduces the amount of data stored, transmitted, and processed, improves spectrum resourcesUtilization rate. A series of MPEG standards are developed as shown in table 1, making digitization a reality. Among them, MPEG-2 is a set of international standards for video and audio compression encoding and data stream format. It definesCoding and decoding technol

Ffdshow can be called the Almighty decoder, encoder. Initially ffdshow was just an MPEG video decoder, but now he can do much more than that. It can decode the video format already far beyond the MEPG4 range, including Indeo video,wmv, MPEG2 and so on. At the same time, it also provides a wealth of processing options, you can sharpen the screen, adjust the brightness of the screen and so on. More than just

subset is implemented by hierarchical encoding. In addition, hierarchical encoding is also applied in Media Asset Management Database browsing and multi-definition video replay in multimedia environments. Hierarchical encoding has advantages and disadvantages. Two advantages: Enable the same data stream to adapt to different decoder features, improving flexibility and effectiveness; for the transition of video broadcast and communication systems to higher time resolution and space resolution, p

Guo Bin, Professor of the Department of television engineering, Beijing Broadcasting Institute 2) Two-Dimensional DCT MPEG adopts the discrete cosine transform (DCT-discrete cosine) proposed by Ahmed N. et al. in 1974.Transform compression algorithm to reduce the space redundancy of video signals (spatial)Redundancy ). Because static images and prediction error signals have very high spatial redundancy, the
