Outdoor best digital satellite isdb tv antenna

The terrestrial transmission system adopted in Japan is not limited to the independent transmission of digital TV, but also includes independent voice and data broadcasting, which can exist alone or be combined arbitrarily to form one program or multiple programs within a bandwidth of 6MHz. ISDB Antenna The ISDB-T system includes a transmitting part and a receiving part. The input of the transmitting part is the output of the source coding part, and the output of the transmitting part is the IF modulated signal added to the input of the transmitter. ISDB-T Antenna In The transmitter is up-converted into a radio frequency signal to the feeder and antenna. In ISDB-T source coding, the image signal is also compressed according to the MPEG-2 standard. According to Rec.ITU-RBT.601-5, ISDB Antenna for Car For SDTV, the image source format should be 720 (704) × 480 pixels, and the sampling frequency should be YUV4:2:0 mode. As for the source coding of sound signals, Japan has neither adopted the MPEG-2 compression standard (ISO/IEC13818-3), the so-called MUSICAM (Masked Universal Subband Integrated Coding and Multiplexing), IDSB antenna for Japan nor The DolbyAC-3 (Audio Coding-3) standard in ATSC is not used, but the AAC (Advanced AC) compression method based on MPEG-4 is used. In the receiving part of the ISDB-T system, the input signal is the radio frequency signal modulated by COFDM, and the output signal is the channel decoding signal added to the input end of the source decoding part.
