Design and Implementation of Network Protection Algorithm for 4K High-definition Broadcast Signal
摘要
Abstract
After the 4K high-definition(HD)broadcast signal is interfered by virus attacks,the video cannot be broadcast nor-mally due to the reduced definition.Based on this,a network protection algorithm is proposed.A 4K HD broadcast signal mo-nitoring module based on video watermarking technology is constructed,and the watermark signal is input into the watermark encoder.After a series of operations of encoding and decoding,the appropriate transform coefficients are adjusted using the three-dimensional wavelet transform algorithm to embed the watermark into the original video signal sequence.The video signal sequence embedded with the watermark signal is detected.When there is no complete watermark in the video signal sequence,an alarm is sent so as to protect the 4K HD broadcast video sequence from virus attacks.The experimental results indicate that the proposed algorithm exhibits excellent protective capabilities against virus attacks.关键词
