This Technote describes the TV Tuner APIs.
The TV Tuner component is included in the Video Startup extension which is part of the Apple Video Player software. The component provides a standard API for accessing the TV tuner hardware available for the various Macintosh systems that have the TV tuner circuit or card available.
Most developers do not need to call the TV Tuner component directly. Any application that uses the SGSettingsDialog function will automatically get TV support without changes to their application.

About TV Tuner Components
Before delving into the specific component calls, there are a few TV-related concepts that are important to discuss. If you are writing software for a specific country, some of these issues may not apply. However, to write global-ready software that uses the TV tuner, each of these issues need to be taken into consideration.
Channel Numbering
The number of channels and the frequencies assigned to those channels varies from country to country. Also, in some countries, users are accustomed to configuring the channels in whatever way they please. For example, in the UK, one user may have his or her TV configured so that BBC is on channel 2, while another may have the TV configured so that BBC is on channel 7. A list of the channel frequencies used by Apple Video Player is provided in the appendix.
Off-Air vs. Cable Channels
Most countries use a different set of channel frequencies, depending on whether a station is being broadcast over the air or via a cable system. In addition, in the US, some cable systems use an alternate set of frequencies (called HRC cable) that differ slightly from standard cable frequencies. Most TVs have an antenna/cable switch that allows the user to select the correct set of frequencies.
Channel Frequencies Are Not Absolute
TV stations do not always broadcast at the defined frequencies. For example, a TV station may broadcast slightly off frequency to avoid interference from another station broadcasting at the same frequency in another part of the country. To accomodate this, TVs generally provide either an automatic or manual fine tuning feature.
Video Standards
Different countries use different video standards. Color encoding, picture size, and frame rate vary from standard to standard. North America and Japan use NTSC, France and parts of eastern Europe use SECAM, while most of the rest of the world uses PAL. Most countries have standardized on a single format for TV broadcasts, but some users may live in areas where they receive TV broadcasts from different countries that use different standards.
TV Standards
Different countries also broadcast using different TV standards, also called systems. Each TV system uses a slightly different range of TV frequencies. Also, the distance between the picture carrier frequency and sound carrier frequency varies from system to system. North America and Japan use system M/N, the UK uses system I, France uses system L, China and eastern Europe use system D/K, while most of the rest of the world uses system B/G. In some parts of the world, multi-standard TVs are common. For example, if a person lives near the French/German border, they might receive some French stations that broadcast using system L and some German stations that broadcast using system B/G.
Stereo Sound
Stereo sound is supported in most countries of the world. Dual language or Second Audio Program (SAP) support is also quite common. In Europe, two different types of stereo broadcast are common: analog FM stereo, and the more recent digital NICAM stereo.
TV Tuner Hardware Description
Many of Apple's multimedia computers have the option of installing a TV tuner card. The TV tuner card becomes an additional input (along with the composite and s-video inputs) to the video digitizer.
There are currently five different TV tuner cards: US (System M/N), Japanese (System M/N), UK (System I), International (System B/G), and French (System L and B/G). The two primary differences between the cards are the tuner modules and the stereo decoding circuitry. From the software point of view, the tuner modules all behave very similarly. The stereo decoders, however, differ in several ways:
- The US and Japanese cards can be set to one of three sound modes: stereo, SAP (second audio program), or mono. The other three cards can be set to stereo, language B, or mono/language A.
- The UK, International, and French cards can detect what type of sound is being broadcast (i.e. stereo, dual language, or mono) and return the information to the application. The US and Japanese tuner cards do not support this.
- The International tuner card can also return which type of stereo broadcast is being received (i.e. NICAM or FM stereo).
Other differences between the tuner cards:
- The US and Japanese tuners support closed captioning, while the UK and International cards support Teletext. The French card does not support Teletext or closed captioning.

Using the TV Tuner Component
All access to the TV tuner is handled by the TV Tuner component. The following code demonstrates how to find and open the TV Tuner component.
ComponentDescription theDesc;
Component id;
ComponentInstance tunerInst;
theDesc.componentType = 'tunr';
theDesc.componentSubType = 0;
theDesc.componentManufacturer = 'appl';
theDesc.componentFlags = 0L;
theDesc.componentFlagsMask = 0L;
id = FindNextComponent(nil, &theDesc);
if (id != nil) {
tunerInst = OpenComponent(id);
if (tunerInst != nil) {
if (GetComponentVersion(tunerInst) < 0x00020000) {
CloseComponent(tunerInst);
tunerInst = nil;
}
}
}
|
FindNextComponent will return nil if the TV Tuner component does not exist or if the component has determined that the tuner hardware does not exist. OpenComponent will return nil if the TV Tuner component has already been opened by another application. The code also checks to make sure the the component version is 2.0 or later. Versions of the compont prior to 2.0 will not function properly and should not be used.
When the application is finished using the component, it should close the component using the CloseComponent call.
In addition to opening the TV Tuner component, the application must also set the input of the video digitizer using the VDSetInput function. To determine which input to use, query each of the digitizer's inputs using the VDGetInputFormat call until you find an input of type tvTunerIn.
short FindTunerInput(ComponentInstance digitizer)
{
short count;
short format;
short i;
short tvInput;
tvInput = -1;
if (VDGetNumberOfInputs(digitizer, &count) == noErr) {
for (i = count; i >= 0; --i) {
if (VDGetInputFormat(digitizer, i, &format) == noErr) {
if (format == tvTunerIn) {
tvInput = i;
break;
}
}
}
}
return(tvInput);
}

TV Tuner Component API Listing
TVSetFrequency
pascal ComponentResult TVSetFrequency(ComponentInstance ci, long frequency);
ci component instance
frequency frequency in hertz
|
This call sets the TV tuner to the selected frequency. The frequency is given in hertz. For example, to a receive a channel that broadcasts at 189.25 Mhz, you would use a frequency value of 189250000.
TVGetFrequency
pascal ComponentResult TVGetFrequency(ComponentInstance ci, long *frequency);
ci component instance
frequency pointer to frequency
|
This call returns the last frequency set using TVSetFrequency.
TVGetCurrentFlags
pascal ComponentResult TVGetCurrentFlags(ComponentInstance ci,
long *standardFlags, long *currentFlags);
ci component instance
standardFlags pointer to standard flags
currentFlags pointer to current flags
|
This function returns a set of flags for which features the TV tuner supports. Currently, the only flags defined are for the different systems that are supported. Because of this, standardFlags and currentFlags will always be the same.
TVSetSoundMode
pascal ComponentResult TVSetSoundMode(ComponentInstance ci, short soundMode);
ci component instance
soundMode sound mode to use
|
Returns tvParamErr if sound mode is out of range. Returns tvNoStereoErr if tuner does not support stereo sound.
This function sets the sound mode to be used by the TV tuner. In a way, this is really a preference more than a setting. The tuner will use the specified sound mode if available, but will revert to the next best thing if necessary. The three sound modes that can be specified are:
- tvMonoMode - This sets the sound mode to mono or, in the case of a dual language broadcast, to language A.
- tvSAPMode - This sets the sound mode to SAP (second audio program) or language B.
- tvStereoMode - This sets the sound mode to stereo. When applicable, it automatically selects the appropriate type of stereo (NICAM or FM).
TVGetSoundMode
pascal ComponentResult TVGetSoundMode(ComponentInstance ci, short *soundMode);
ci component instance
soundMode pointer to a sound mode
|
Returns tvNoStereoErr if tuner does not support stereo sound.
This function returns the sound mode last requested using the TVSetSoundMode function. This does not necessarily correspond to the sound mode currently being received. For that information, use the TVGetAvailableSoundMode routine.
TVGetAvailableSoundMode
pascal ComponentResult TVGetAvailableSoundMode(ComponentInstance ci,short *soundMode);
ci component instance
soundMode pointer to a sound mode
|
Returns tvNoStereoErr if tuner does not support stereo sound.
If supported by the stereo decoding hardware, this function will return the sound mode that is actually being received. The four sound modes that can be returned are:
tvUnknownMode - This is returned if the hardware does not support sound mode detection or if the sound mode could not be determined (e.g. no signal is being received).tvMonoMode - This is returned if a mono signal is being received.tvSAPMode - This is returned if an SAP or dual language signal is being received.tvStereoMode - This is returned if a stereo signal is being received.
TVGetAvailableSoundType
pascal ComponentResult TVGetAvailableSoundType(ComponentInstance ci,short *soundType);
ci component instance
soundType pointer to a sound type
|
Returns tvNoStereoErr if tuner does not support stereo sound.
If supported by the stereo decoding hardware, this function will return the type of sound that is actually being received. The three sound types that can be returned are:
tvUnknownSoundType - This is returned if the hardware does not support sound type detection or if the sound type could not be determined (e.g. no signal is being received).tvAnalogSoundType - This is the most common type of sound broadcast.tvDigitalSoundType - This is a fairly recent type of digital sound broadcast, commonly called NICAM. It is common in some European countries.
TVSetSoundSearchSpeed
pascal ComponentResult TVSetSoundSearchSpeed(ComponentInstance ci, short speed);
ci component instance
speed search speed
|
Returns tvNotSupportedErr if function not supported by tuner. Returns tvParamErr if invalid search speed specified.
If supported by the stereo decoding hardware, this function will set the speed at which the hardware determines the available sound mode and type. Using tvSoundSlowSpeed is more accurate than tvSoundFastSpeed, but may take several seconds to determine the sound mode and type.
TVGetSoundSearchSpeed
pascal ComponentResult TVGetSoundSearchSpeed(ComponentInstance ci, short *speed);
ci component instance
speed pointer to speed
|
Returns tvNotSupportedErr if function not supported by tuner.
This function returns the sound search speed set using the TVSetSoundSearchSpeed function.
TVSetStandard
pascal ComponentResult TVSetStandard(ComponentInstance ci,unsigned long standard);
ci component instance
standard TV standard
|
This function sets the TV standard to use (i.e. system I, system M/N, etc.). When using a dual standard, specify only one of the two standards, not both. For example, to set system B/G use tunrStandardB or tunrStandardG, but not tunrStandardB+tunrStandardG.
TVGetStandard
pascal ComponentResult TVGetStandard(ComponentInstance ci, unsigned long *standard);
ci component instance
standard pointer to TV standard.
|
This function returns the TV standard set using the TVSetStandard function.
TVGetDefaultStandard
pascal ComponentResult TVGetDefaultStandard(ComponentInstance ci, unsigned long *standard);
ci component instance
standard pointer to TV standard
|
This function returns the default TV standard.
