摘要：

TSBB (Transmitter Station BaseBand) is one of the main subsystems of the D-DBS system for KOREASAT. It pre-processes, compresses, packetizes and multiplexes the program and data sources, and send the multiplexed output to RF/IF module for transmission. TSBB has the following characteristics; video resolution of up to 720 x 480, optional usage of aspect ratio between 4x3 and 16x9, closed captioning, sind multiple languages (up to 4 languages). TSBB employs MPEG-2 MP @ML for video compression, and MPEG-1 Layer II for audio compression. Data program is available up to 2Mbps. TSBB also scrambles programs for subscription and pay-per-view channels. In this paper, we introduce system requirements, system design and system implementation for TSBB. We also shows test results for TSBB functions which include video/audio/data broadcasting and encoder/MUX configuration, and test results for TSBB performance.
