UHD/HD/SD Satellite contribution and distribution 

GREDOS is the Sapec solution for the video transmission and reception over Satellite and DTT. Gredos is a family of products, each one developed using cutting-edge technology for professional Broadcast environments and the different existing scenarios.

GREDOS solutions guarantee Broadcasters with reliability and low latency performance for high quality contribution and distribution links over:

  • Satellite. Supporting DVB-S/S2/S2X
  • Terrestrial. Supporting ATSC, DVB-T/T2, ISDB-T
  • Cable: supporting DVB-C/C2

Each of the following GREDOS family has been developed for different applications

GREDOS GHMXX32: Encoder Modulator. With high quality encoder platform (H.264/MPEG-2 or HEVC/H.264/MPEG-2) with support of 4:2:2 & 4:2:0 on HD/SD. On the modulation side, the most usual configuration is with a DVB-S/S2/S2x Modulator with IF output, 10 MHz reference, and modulations as 16-QAM, QPSK, 8PSK, 16APSK and 32APSK and Symbol Rates of up to 75 Msps. It is also possible, to integrate a DTT modulator for different applications (DVB, ATSC, ISDB). 

GREDOS GHRXX02 It is a complete multiformat receiver/decoder that offers the option of receiving L-Band satellite signals via a 4-port satellite receiver for DVB-S/S2/S2x and demodulate QPSK/8PSK signals (all FEC) and 16/32 APSK.

GHRXX02 decodes HEVC/H.264/MPEG.2 on HD/SD and 4:2:2/4:2:0. It also supports BISS 1/E decryption, PID filtering, Dual CAM DVB-CI, IP output, DTT reception and Down Conversion. A very versatile receiver that addresses many different scenarios of satellite reception and distribution.

GREDOS GUR5002 a multiformat receiver-decoder based on its predecessor the GHRXX02, that in addition it includes the possibility of decoding UHD (4k) signals on 4:2:0 10 bit, with HDR support and distribute over a 4x 3G-SDI interface.

GREDOS GGR1000 is the humbler member of the GREDOS family. It is a multiformat gateway for reception of any signal format and its distribution over Transport stream (ASI or IP) without any decoding functionality. GGR can receive satellite signals (DVB-S/S2/S2x), as well as DTT signals (DVB-T/T2/ISDB-T/C/C2/8VSB).
