7. Conclusion
The advantages brought by compression of the TV signal are as follows: reducing the frequency
range of telecommunication channel which transmits TV signal, reducing the memory capacity
required for recording images (storing images), access to data is reduced because the faster
skips over the material, provided a data transfer in real time, it reduces the needed RAM
memory and hardware becomes less expensive and leads to the miniaturization of hardware
in the television. By reducing the number of bits, less power is required to broadcast; for
example, if the transmitter of the same power is broadcasting analog and digital signal, for
digital reception antenna of smaller diameter is required.
To ensure reliable communication between users who use equipment and software from
different manufacturers, standardization of methods of compression was carried out. So today,
depending on the quality and use (television, multimedia services, videoconferencing, video
telephony, etc.), there are several standards (JPEG, MPEG-1, MPEG-2, MPEG-4, H.261, H.263,
H. 264, H.265, etc.).
Since it is a new technology that just catches the “momentum” toward global use, UHD is the
future of television. Also, UHD offers the ultimate user experience and creates opportunities
for the entire industry. 4K and 8K services will stimulate the growth of broadband, as well as

the expansion of TV services in emerging markets. Consequently, the compression standard
for TV in the near future will be HEVC/H.265.
