Android application package of about 19.3 MB whose Chinese name refers to Tiejie Video (泰捷视频), a video player app often used on TV boxes, with version 9.9.9.9 in the name. It is software, not a schematic or firmware image. Technicians who service set-top boxes or Android TV devices sometimes sideload such APKs after a reflash to restore user apps. Install only on compatible Android hardware, and note that an unusual version number like this may be a modified build, so scan it before use.
