DIGITAL SATELLITE BROADCASTING RECEIVER FOR SIMULTANEOUSLY TUNING MULTI-CHANNEL THROUGH A SINGLE SATELLITE BROADCASTING RECEIVER AND SIMULTANEOUSLY RECEIVING DIFFERENT CHANNELS TUNED THROUGH RESPECTIVE DISPLAY DEVICES

摘要

Purpose: a digital satellite broadcast receiver is provided to while adjusting multichannel by a single satellite broadcast reception converter, while receiving different channel, passes through the representative display equipment adjustment being located in multiple separate spaces. Construction: a multi-tuner unit includes multiple tuner (14-1,14-2,.., 14-n) and demodulator satellite-signal be converted to TP (TransPort streams) signals by adjusting and demodulation of satellite signal to corresponding with channel respectively, export TP signals. The parts one CAS (conditional access system in application) (144) descramble TP signals. Descramble TP signals are divided into the audio signals and vision signal of corresponding channel by one multi-signals separation device (142). More than one decoding portion (143) decodes the vision signals of audio signals and corresponding channel by decoding operation accordingly more respectively and exports decoded audio signal, positions respectively in multiple separate spaces to the vision signal of multiple display devices.
