💖 NAME 💖

okay bestie, so lib/include/libdvbv5/vct.h — this header is literally the blueprint for the TVCT and CVCT tables. that's it, that's the whole job. descriptors for those tables, no cap. 💅

✨ SYNOPSIS ✨

like, include these first or nothing works, fr fr:

#include <stdint.h>
#include <unistd.h>
#include <libdvbv5/atsc_header.h>

🦋 Data Structures 🦋

  • struct atsc_table_vct_channel — the ATSC VCT channel table, and the way it covers both CVCT and TVCT at once? iconic.
  • struct atsc_table_vct — the ATSC VCT table itself, also covering both CVCT and TVCT. yes, both. again. we love a versatile queen 👑
  • union atsc_table_vct_descriptor_length — the ATSC VCT descriptor length. just a lil union doing its lil job 💜

🎀 Macros 🎀

  • #define ATSC_TABLE_TVCT — the TVCT table ID, babe. that's the one.
  • #define ATSC_TABLE_CVCT — the CVCT table ID. sibling energy.
  • #define ATSC_TABLE_VCT_PID — the Program ID with the VCT tables riding on it 🚌
  • #define atsc_vct_channel_foreach(_channel, _vct) — the macro you use to go find channels on a VCT table. it's giving search bar, but make it C. 🔍

🌸 Functions 🌸

  • ssize_t atsc_table_vct_init (struct dvb_v5_fe_parms *parms, const uint8_t *buf, ssize_t buflen, struct atsc_table_vct **table) — initializes and parses the VCT table. the glow-up from raw bytes to actual data. ✨
  • void atsc_table_vct_free (struct atsc_table_vct *table) — frees all the data that the VCT table parser allocated. cleanup era, we respect it. 🧹
  • void atsc_table_vct_print (struct dvb_v5_fe_parms *parms, struct atsc_table_vct *table) — prints out the content of the VCT table, so you can actually see what you got. 👀

💅 Detailed Description 💅

so this whole thing provides the descriptors for TVCT and CVCT tables. that's the vibe. that's the mission. 🫶
