The Spring Festival Gala is a must-see for the Chinese people to reunite with their family. CCTV's 2015 Spring Festival Gala held the first-ever live webcast of the Spring Festival Evening Gala. It was finally decided that there would be no other choice than cable TV for Spring Festival Gala. No matter whether you use a computer or a box, you will not have to pay for cable TV. But wait until the "New Year's Eve" to serve, the box is not wrong, the computer's Caton and fuzzy is more difficult to accept, showing power and HDTV cable can not match.
The on-demand function of the on-demand network television is better than the cable TV, and the live broadcast effect of the cable TV is better than the network TV. Both have their own advantages. Watching Internet TV and cable TV need to use two boxes with different functions. Many users will choose one, either simply become network TV users, or simply become cable TV users, otherwise two functions need to be in two boxes. Tossing back and forth is very troublesome.
This is mainly because the two types of boxes have different requirements for the image quality and the quality of the received signal, and the compatibility is difficult. The image quality of the network box depends on the set-top box's ability to handle network video streams. The dual-core box will be competent, but when it exceeds dual-core, whether it is quad-core or eight-core, the image quality will not change. This depends on the CDN. Distribution capabilities. Therefore, even if the network box uses more core CPUs to run at higher speeds, and the number of users in the peak hours of the Internet exceeds the server capacity limit, there is no difference in Caton, and even the relationship between broadband access in the home is 10M or 100M. . The main reason is that the network box lacks the hardware DVB module that receives the live TV. This DVB hardware module can handle up to 100M of live streaming to ensure that data is not lost and not missed. The hardware module cannot be implemented with a CPU, so whether it is a 4-core or 8-core network box, the image quality and stability cannot be compared with the cable box.
To make the network box have the high quality of the cable box, the technical standards of the cable box must be introduced on the network box, and the obstacles to the regionalization of the cable box must be overcome.
Since 2013, there have been companies that have begun trying to combine the hardware and software technology standards of the two boxes to take advantage of the two boxes. However, this convergence depends on the chip manufacturers, and some chip manufacturers have also seen this opportunity and have taken the lead in introducing a box chip that incorporates network-integrated DVB modules to improve image quality. The chips that support high-quality live image quality are Amlogic's S805 and S812, as well as the H3. In 2015, chips supporting DVB modules will enter the popular period.
You know, hardware support alone is not enough and you need the support of live TV operating systems. At present, the live TV operating systems that can meet the requirements are DTVOS from Taixin Electronics and TVOS from SARFT. DTVOS is the only live TV operating system verified by more than 300 cities. TVOS is currently only planning to pilot within the closed range of television operators, and there is no timetable for marketization.
The introduction of DVB modules and live TV operating systems has brought the box's technology and quality levels to a new level.
