If the channel specifies an idType attribute value supported by the OITF, and the combination of properties defines a valid channel, the OITF SHALL relay the channel switch request to a local physical tuner that is currently not in use by another video/broadcast object and that can tune to the specified channel. If no tuner satisfying these requirements is available (i.e. all physical tuners that could receive the specified channel are in use), the request SHALL fail and OITF SHALL trigger the function specified by the onChannelChangeError property, specifying the value ‘2’ (“tuner locked by other object”) for the errorState and dispatch the corresponding DOM 2 event (see below). If multiple tuners satisfying these requirements are available, the OITF selects one. If the channel specifies an IP broadcast channel, and the OITF supports idType ID_IPTV_SDS or ID_IPTV_URI, the OITF SHALL relay the channel switch request to a logical ‘tuner’ that can resolve the URI of the referenced IP broadcast channel. If no logical tuner can resolve the URI of the referenced IP broadcast channel, the request SHALL fail and the OITF SHOULD trigger the function specified by the onChannelChangeError property, specifying the value 8 (“cannot resolve URI of referenced IP channel”) for the errorState, and dispatch the corresponding DOM 2 event. The optional attribute contentAccessDescriptorURL allows for the inclusion of a Content Access Streaming Descriptor (the format of which is defined in Annex E.2) to provide additional information for dealing with IPTV broadcasts that are (partially) DRMprotected. The descriptor may for example include Marlin action tokens or a previewLicense. The attribute SHALL be undefined or null if it is not applicable. If the Transport Stream cannot be found, either via the DSD or the (ONID,TSID) pair, then a call to onChannelChangeError with errorstate=5 (“unknown channel”) SHALL be triggered, and the corresponding DOM 2 event dispatched. If the OITF succeeds in tuning to a valid transport stream but this transport stream does not contain the requested service in the PAT, the OITF SHALL remain tuned to that location and SHALL trigger a call to onChannelChangeError with errorstate=12 (“specified channel not found in transport stream”), and dispatch the corresponding DOM 2 event.

The OITF SHALL visualize the video content received over the tuner in the area of the browser allocated for the video/broadcast object. If the OITF cannot visualize the video content following a successful tuner switch (e.g., because the channel is under parental lock), the OITF SHALL trigger the function specified by the onChannelChangeError property with the appropriate channel and errorState value, and dispatch a corresponding DOM 2 event (see below). If successful, the OITF SHALL trigger the function specified by the onChannelChangeSucceeded property with the given channel value, and also dispatch a corresponding DOM 2 event. @param channel The channel to which a switched is requested. If the channel object specifies a ccid, the ccid identifies the channel to be set. If the channel does not specify a ccid, the idType determines which properties of the channel are used to define the channel to be set, for example, if the channel is of type ID_IPTV_SDS or ID_IPTV_URI, the ipBroadcastID identifies the channel to be set.
