NetcastTVService

NetcastTVService provides capabilities for LG Smart TVs running Netcast versions 3.x and 4.x (model years 2012-2014). The media playback functionality of NetcastTVService may be proxied through to DLNAService to avoid requiring pairing. Commands & subscriptions on Netcast occur over HTTP.

The following capabilities are provided by the Netcast OS:

  • Media playback
  • Media control
  • App launching*
  • Volume control*
  • Text input control*
  • Key control (fiveway)*
  • Mouse control*
  • Power control*
  • TV control (change channels, get channel info)*
  • External input control*

  • = requires pairing

Inherited Methods

+ (NSDictionary *) discoveryParameters

A dictionary of keys/values that will be used by the DiscoveryProvider used to discover this DeviceService. Some keys that are used are: service name, SSDP filter, etc.

+ (DeviceService *) deviceServiceWithClass:(Class)_class serviceConfig:(ServiceConfig *)serviceConfig
Parameters:
  • _class
  • serviceConfig: serviceConfig
+ (BOOL) shouldDisconnectOnBackground

Static property that determines whether a DeviceService subclass should shut down communication channels when the app enters a background state. This may be helpful for apps that need to communicate with web apps from the background. This property may not be applicable to all DeviceService subclasses.

Sets the shouldDisconnectOnBackground static property. This property should be set before starting DiscoveryManager for the first time.

+ (void) setShouldDisconnectOnBackround:(BOOL)shouldDisconnectOnBackground
Parameters:
  • shouldDisconnectOnBackground
- (instancetype) initWithServiceConfig:(ServiceConfig *)serviceConfig
Parameters:
  • serviceConfig
- (BOOL) hasCapability:(NSString *)capability
Parameters:
  • capability
- (BOOL) hasCapabilities:(NSArray *)capabilities
Parameters:
  • capabilities
- (BOOL) hasAnyCapability:(NSArray *)capabilities
Parameters:
  • capabilities
- (void) connect

Will attempt to connect to the DeviceService. The failure/success will be reported back to the DeviceServiceDelegate. If the connection attempt reveals that pairing is required, the DeviceServiceDelegate will also be notified in that event.

- (void) disconnect

Will attempt to disconnect from the DeviceService. The failure/success will be reported back to the DeviceServiceDelegate.

- (void) pairWithData:(id)pairingData

Will attempt to pair with the DeviceService with the provided pairingData. The failure/success will be reported back to the DeviceServiceDelegate.

Parameters:
  • pairingData –

    Data to be used for pairing. The type of this parameter will vary depending on what type of pairing is required, but is likely to be a string (pin code, pairing key, etc).

- (void) closeLaunchSession:(LaunchSession *)launchSession success:(SuccessBlock)success failure:(FailureBlock)failure

Every LaunchSession object has an associated DeviceService. Internally, LaunchSession's close method proxies to it's DeviceService's closeLaunchSession method. If, for some reason, your LaunchSession loses it's DeviceService reference, you can call this closeLaunchSession method directly.

Parameters:
  • launchSession –

    LaunchSession to be closed

  • success: success –

    (optional) SuccessBlock to be called on success

  • failure: failure –

    (optional) FailureBlock to be called on failure
