Extensions to video/broadcast for current channel information
If an OITF has indicated support for extended tuner control (i.e. by giving value true to element <extendedAVControl> as specified in section 9.3.6 in its capability description), the OITF SHALL support the following additional properties and methods on the video/broadcast object.
The functionality as described in this section is subject to the security model of section 10.1.3.8.
Note the property onChannelScan and methods startScan and stopScan have been moved to section 7.13.9.
|readonly Channel currentChannel|
|The channel currently being presented by this embedded object if the user has given permission to share this information, possibly through a mechanism outside the scope of this specification. If no channel is being presented, or if this information is not visible to the caller, the value of this property SHALL be null. The value of this property is not affected during timeshift operations and SHALL reflect the value prior to the start of a timeshift operation, for both local and network timeshift resources.|
