* Some Android based TVs export (in addition to the brand specific channel list files) a file named MtkChannelList.xml
* Examples are Philips channel list formats 120 and 125
* Some Android based TVs export an XML file with the format described below.
* Examples are Philips channel list formats 120 and 125 and Sony BRAVIA 7 (2024).
* However there are differences between Philips and Sony:
* - Sony lacks a number of XML elements
* - Sony seems to manage TV, Radio and Data channels internally in separate lists, all starting at 1, while Philips seems to use one combined list with no duplicate major_channel_numbers

* <service_list_infos>
