Satellite reception is the primary source of program signal for any broadcasting television system, especially for the digital television front-end systems of network companies. However, the commonly available satellite receivers on the market are typically 1RU structured distributed satellite receivers. Each satellite receiver can provide reception capabilities for 1 to 4 satellite frequency points. Therefore, in any moderately sized digital television system, we can see rows of cabinets used to house various satellite receivers.
Starting from the satellite antenna, the satellite signal needs to be amplified and distributed in stages before being sent to the satellite receiver. The signals received by the satellite receiver need to be aggregated through numerous cables (ASI/IP). This inadvertently wastes a significant amount of rack space, increases the difficulty of cable layout, and adds considerable challenges for future system maintenance (maintenance personnel need to be familiar with the operation and parameters of a large number of devices).
To address the numerous shortcomings of the satellite reception component mentioned above, Norway's AppearTV has launched a new satellite reception module, the DVB-S/S2X Demodulator, which is equipped on the latest X20/X10 high-capacity platform, effectively solving this issue.
This module only provides four external RF input interfaces (F-type), but it is equipped with 32 satellite reception high-frequency heads internally. To ensure flexible signal routing, two 2x16 L-band matrices are also built into the board, as shown in the figure below:
- The module is equipped with up to 32 satellite reception high-frequency heads for receiving signals from 32 satellite channels;
- Supports DVB-S/S2/S2X modulation modes
- Supports modulation from QPSK to 256APSK;
- The board supports BISS decryption;
- Built-in 2x16 L-band matrix;
- Internal switching, with signal input through the gigabit/10-gigabit IP output ports mounted on the chassis;
It is easy to imagine that with this board in the broadcasting and television system, satellite reception no longer requires the large satellite receiving systems of the past. Instead, only a small amount of satellite signals need to be sent to this board for reception. The final output can also be processed through high-capacity IP network cables into the core data switch.
For certain encrypted programs, it can be paired with the decryption module of the AppearTV XC5x00 platform for processing. This meets all the satellite reception needs of the entire system.
Based on such a high-capacity satellite reception functional module, it is not an exaggeration to say that this could be the ultimate embodiment of satellite reception in the future; it is the terminator of satellite reception.
