🌸 NAME 🌸

dvbv5_set_delivery_system — literally sets the delivery system for a DVBv5 API call 💫

---

🎀 SYNOPSIS 🎀

int dvbv5_set_delivery_system (struct dvb_frontend *fe , u32
desired_system );

like, that's the whole vibe. one call, two args, we move 🌈

---

🦋 ARGUMENTS 🦋

• fe — the frontend struct 💖 that's your frontend bestie right there
• desired_system — the delivery system that the user requested 👑 like, what they actually want

---

✨ DESCRIPTION ✨

so a DVBv5 call knows what the desired system it wants is. so... set it. periodt 💅 that's the whole job.

but here's the tea ☕ — there are a few known issues with early DVBv5 applications that this logic also handles, and honestly? iconic of it to be so considerate 🥺

1. some early apps use SYS_UNDEFINED as the desired delivery system 🙈 that is, lowkey, an API violation — but we're not out here breaking userspace, so it gets converted to the first supported delivery system. we're nice like that 🫶
2. some apps might be using a DVBv5 call in the wrong way, passing — for example — SYS_DVBT instead of SYS_ISDBT 💀 this happens because early usage of ISDB-T provided backward compat with DVB-T. iykyk.

ngl bestie, those are the exact known issues listed. no extra lore, that's the list fr fr.
