Why did your smartphone "1Seg" decrease?/ The smartphone's "USB Type-C audio" is deep ...

Recently, the number of smartphones equipped with TV tuners (full segment / 1Seg) has decreased ...

　"ITMEDIA Mobile Weekly Top10", which summarizes the number of weekly articles accesses in ITMEDIA Mobile and introduces the top 10 articles. This time, we have summarized the week from November 29, 2021 to December 5, 2021. [Photo] The USB Type-C analog audio conversion adapter cannot be used in the PIXEL series. The number of accesses in this tallying period is the recent Android smartphone, and the installation rate of TV tuners (full segment / one-segment) has decreased. It was an article I considered. Due to the appearance of unlimited capacity plans and enhancement of video distribution services, I think that the number of situations using TV tuner functions has decreased compared to before. In addition, TV tuners are also used as a function, such as being unable to use unless the TV radio waves enter, and that they cannot be received unless they connect earphones except for some models. I think it is the cause. Recently, there are also HDD recorders and TV tuners where you can watch TV programs via Wi-Fi (wireless LAN) or mobile network if you put it at home. If you prepare it, you don't have to prepare a smartphone with a TV tuner forcibly (?). However, in the event of a disaster, "broadcasting" is useful. Recently, the increasing number of smartphones with FM tuners may be an "alternative measure" to meet the needs of broadcasting. The second place in the number of accesses was a column that wrote that there were two types of "analog connection" and "digital connection" on the USB Type-C connection audio device. The USB Type-C terminal itself is also assumed that signals other than USB (universal serial bus) input and output. In fact, one of the signals is analog voice input and output. However, if the USB Type-C terminal has an analog voice input / output function, only the method of connecting analog audio devices via an audio conversion adapter as shown in the article is allowed. For smartphones and tablets that have only recent USB Type-C terminals, if you select a digital connection type (built-in DAC / ADC), there is no problem with voice output. However, in rare cases, it may not work well due to compatibility issues. Some manufacturers that handle adapters and earphones have published "operation confirmation models", so we recommend that you research before you buy them as much as possible. By the way, my personal recommendation is the stereo head set "STH50C" sold by Sony (formerly Sony Mobile Communications). STH50C is recognized as a USB audio device, so it can be used on Windows PC. It can be used conveniently in my house, which is full of various devices. I don't think it's a waste to end the sale ...
