This article presents a multistandard digital high-definition (HD)/standard-definition (SD)-serial digital interface (SDI) audio multiplexer (embedder) capable of inserting and replacing existing ancillary Audio Engineering Society-European Broadcasting Union packets. The insertion of audio packets in SD-SDI video is achieved with an ad hoc modular unit that shifts the existing audio packets in the video frame. This block enables the use of the entire multiplexer system in cascaded… CONTINUE READING
