If your receiver also has built-in Wi-Fi, you can easily connect to your home network to update the firmware. Manufacturers and programmers regularly modify, improve the firmware of the receivers so that they provide the best possible operation of the device.
The software updating will help get rid of freezes and other failures in the receiver. Perhaps new channels will appear in the updated firmware, new functions will start working, the receiver will be able to read media files from external media, go online to watch the weather forecast or videos on YouTube.
Most importantly, be careful and choose the software specifically for your receiver model. Incorrectly, selected firmware can ruin your receiver so badly that you have to buy a new one.
