What is a digital set-top box As the name suggests, a set-top box refers to a box on top of a TV, and is a type of household appliance that extends the functions of a TV. Set-top boxes are divided into analog set-top boxes and digital set-top boxes according to the type of signals received. Analog set-top boxes receive analog signals, and digital set-top boxes receive digital signals. A digital set-top box is a multimedia terminal with a hardware architecture similar to a home computer and a dedicated real-time operating system and application software. The development direction of cable TV digital set-top box According to the national digital TV development plan, China will basically realize the popularization of digital TV in 2010. By 2015, when the output of analog TV signals is turned off, Chinese TV will fully advance into the digital era. In fact, digital TV broadcasting has begun to test the market response and has achieved good results. I saw a piece of news today that said: "Beijing digital TV has been broadcasting for 4 days, and 3000 set-top boxes have been sold out." It seems that this market is about to take off.

Users connect the cable feeder to the digital set-top box, use the AV cable to connect to the AV input terminal of the TV, and then use the digital set-top box remote control to select channels and programs.
Digital TV broadcasts in the AV program of the TV. When watching, the TV program is converted to a channel that usually plays DVDs or videos. All digital TV programs are in the AV channel. When selecting, you need to use a set-top box remote control. The operation process is similar to playing a DVD. If you do not want to watch digital TV programs, press the TV remote control AV conversion key to return to the original program.
As Syndy mentioned, digital set-top boxes are a transitional product that connects analog TV and digital TV, so the key to its promotion and development lies here. Most consumers are reluctant to purchase transitional products with relatively short life cycles because of economic considerations. Therefore, although set-top boxes can extend the life cycle of analog TVs, they will still encounter difficulties in marketing. In view of this, manufacturers must try to change this transitional product image of set-top boxes and strive to turn them into a more viable product by integrating new functions.
For example, you can integrate functions such as DVD playback, digital video recording, digital photo display, and video games with a set-top box, and focus the promotion on its independent functions. The key is to avoid giving consumers the impression that the set-top box is an accessory to analog TV, but to make them feel that this is a brand new digital product and can help extend the life of analog TV products. From the cost point of view, this type of product can be made almost the same as the DVD products on the market, but the profit margin can be much larger.
