Types ¶
type Channel ¶
type Channel struct {
Name string
FrequencyHz uint
Modulation Modulation
VideoPID uint
AudioPID uint
ProgramID uint
}
Channel represents the definition of an ATSC television channel.
func ParseChannelsConf ¶
ParseChannelsConf parses Channels from an azap-compatible channels.conf file read from r.
Each line of the file defines a single channel, and is formatted as 6 colon-separated fields corresponding to the fields of Channel as follows:
Name:FrequencyHz:Modulation:VideoPID:AudioPID:ProgramID
FrequencyHz, VideoPID, AudioPID, and ProgramID are all represented in decimal form.
The https://github.com/stefantalpalaru/w_scan2 utility is useful for generating a compatible file. For example, to scan for terrestrial broadcast channels in the United States of America:
w_scan2 -f a -c us -X > channels.conf
type Modulation ¶
type Modulation string
Modulation represents the modulation of an ATSC television channel.
const ( // Modulation8VSB may also be parsed as "VSB_8" in a channels.conf file. Modulation8VSB Modulation = "8VSB" ModulationQAM64 Modulation = "QAM_64" ModulationQAM256 Modulation = "QAM_256" )
The following are the normalized Modulation values for a Channel.
