Interfacing controllers in real-time encoding/decoding system for HDTV editor

Abstract

This thesis introduces an implementation of interfacing controllers between each module in the Real-time Encoding/Decoding System (REDS) for HDTV applications. These controllers are composed of three parts: One is the SMPTE260M transceiver, another is the VBUS Controller, and the other is NESH-REDS interfacing Controller. The first one is an SMPTE260M Transceiver. It composes Rx Controller and Tx Controller. The functions of the Rx Controller are to retrieve the incoming active data and to widen the bandwidth. It causes to improve the operating efficiency of the MVP and the memory devices and to make noise insensitive. And the Tx Controller takes a play in transmitting the outgoing video data in SMPTE260M. It is performed by attaching the ancillary data incoming through the receiving part to the active video data. The advantage of this method is that the transmitting process needs not make the complicated synchronous clocks for SMPTE260M formatting. The second one is a VBUS controller. It supports the REDS in parallel processing. It also helps the REDS perform the encoding/decoding process in a given time. The third one is a NESH-REDS interfacing controller. It accomplishes the communication between two different systems.
