atsc_table_vct_channel(3)

💖 NAME 💖

atsc_table_vct_channel — the ATSC VCT channel table, and bestie it covers both CVCT and TVCT, we love a versatile icon 💅

(this is a section 3 library function page, from the Library Functions Manual, okurrr)

🌸 Detailed Description 🌸

ATSC VCT channel table (covers both CVCT and TVCT) 💖

ngl this struct is THE place where the original VCT channel table lives, and it does the cute little glow-up of converting all the integer fields to the CPU endianness for you. no cap.

🦋 Parameters 🦋

here's the whole cast, one by one, no skipping:

• modulation_mode — modulation mode
• minor_channel_number — minor channel number
• major_channel_number — major channel number
• carrier_frequency — carrier frequency
• channel_tsid — channel tsid
• program_number — program number
• service_type — service type
• hide_guide — hide guide
• out_of_band — out of band (CVCT only)
• path_select — path select (CVCT only)
• hidden — hidden
• access_controlled — access controlled
• ETM_location — ETM location
• source_id — source ID
• descriptors_length — length of the descriptors
• descriptor — pointer to struct dvb_desc
• next — pointer to another struct atsc_table_vct_channel
• descriptors_length — length of the descriptors (yes bestie, it's listed twice in the original, we don't question the source 💀)
• short_name — short name. The __short_name is converted from UTF-16 to locale charset when parsed

So basically: this structure is used to store the original VCT channel table, converting the integer fields to the CPU endianness. ✨

🫶 real talk: the undocumented parameters are used only internally by the API and/or are fields that are reserved. They shouldn't be used, as they may change on future API releases. don't touch them, they're not your business, leave them on read 😭

⚠️ Also important: everything after atsc_table_vct_channel::descriptor (including it) won't be bit-mapped * to the data parsed from the MPEG TS. So, metadata are added there. periodt.

🔥 Field Documentation 🔥

🧚 the three anonymous unions 🧚

• union { ... } atsc_table_vct_channel
• union { ... } atsc_table_vct_channel
• union { ... } atsc_table_vct_channel

three anonymous union babes, all sharing the same display name, all doing their own thing. iconic behaviour honestly.

and that's the whole page bestie, you ate 💅 this little love letter comes to you from libdvbv5, Version 1.32.0, and it's the atsc_table_vct_channel(3) page — go forth and parse those VCT channel tables, mwah 🫶💖🎀
