Identifies the presentation tool to be used.

If not specified, the player is determined by the object type, defined by the type attribute of the <media> element, or inferred by the file extension of the src attribute value of the <media> element.

“true” or “false”.

The default value is “false”.

“close” or “keep”.

The default value is “close.

“systemScreen(i)” or “systemAudio(i)”, where i is a non-negative integer.

The default value is the same device class that runs the NCL player.

Specifies the device class where the media object will be presented.

There are two different types of device classes: active and passive. In an active class, a device is able to run some media players for <media> element presentations. In a passive class, a device is not required to run media players, only to exhibit a bit map or a sequence of audio samples received from another device.

The “systemScreen(1)” and “systemAudio(1)” are reserved to passive classes, and “systemScreen(2)” and “systemAudio(2)” are reserved to active classes.

The “explicitDur” property is specified according with one of the following syntax:

1. “Hours:Minutes:Seconds.Fraction”, where “Hours” is an integer in the [0,23] interval, “Minutes” is an integer in the [0,59] interval, “Seconds” is an integer in the [0,59] interval, and “Fraction” is a positive integer.
2. Seconds”s”, where Seconds is a positive real number.

For continuous media, the default value is set to the duration of the content, otherwise, it must be set to nil.

Positive integer.

When this property is not defined, the object is considered as if no focus could be set to it.

Specifies an index for the <media> element to which the focus may be applied.

Note: When an element on focus is selected by pressing the “activate (select or enter) key”, the focus control shall be passed to the <media> element renderer (player). The player may then follow its own rules for navigation. The focus control shall be passed back to the NCL Player when the “back key” is pressed. In this case, the focus goes to the element identified by the the “service.currentFocus” property of the settings node (<media> element of “application/x-ncl-settings” type).

A real number in the range [0,100] ending with the character “%” (e.g. 30%), or an integer non-negative value specifying the attribute in pixels. For pixel values, the “px” unit qualifier may be omitted.

The default value is “0%”, if the bottom value is not specified.

If the “top” and “height” values are specified, it must be computed based on these values. Otherwise, it must be a real number in the range [0,100] ending with the character “%” (e.g. 30%), or an integer non-negative value specifying the attribute in pixels. For pixel values, the “px” unit qualifier may be omitted.

The default value is “0%”, if the attribute value cannot be computed from the height and top attributes.

A real number in the range [0,100] ending with the character “%” (e.g. 30%), or an integer non-negative value specifying the attribute in pixels. For pixel values, the “px” unit qualifier may be omitted.

The default value is “0%”, if the right value is not specified.

If the left and width values are specified, it must be computed based on these values. Otherwise, it must be a real number in the range [0,100] ending with the character “%” (e.g. 30%), or an integer non-negative value specifying the attribute in pixels. For pixel values, the “px” unit qualifier may be omitted.

The default value is “0%”, if the attribute value cannot be computed from the width and left attributes.

A real number in the range [0,100] ending with the character “%” (e.g. 30%), or an integer non-negative value specifying the attribute in pixels. For pixel values, the “px” unit qualifier may be omitted.

The default value is “0%”.

A real number in the range [0,100] ending with the character “%” (e.g. 30%), or an integer non-negative value specifying the attribute in pixels. For pixel values, the “px” unit qualifier may be omitted.

The default value is “0%”.

“white”, “black”, “silver”, “gray”, “red”, “maroon”, fuchsia”, “purple”, “lime”, “green”, “yellow”, “olive”, “blue”, “navy”, “aqua”, or “teal”. It may also be the reserved value “transparent”.

The default value is “transparent”.

RGB color defined using a hexadecimal (hex) notation for the combination of Red, Green, and Blue color values (RGB). The lowest value that can be given to one of the light sources is 0 (hex 00). The highest value is 255 (hex FF).

It may also be defined by the reserved words: “white”, “black”, “silver”, “gray”, “red”, “maroon”, fuchsia”, “purple”, “lime”, “green”, “yellow”, “olive”, “blue”, “navy”, “aqua”, or “teal”.

“true” or “false”.

The default value is “false”.

Allows the object presentation to be seen or hidden.

When the visible property associated with a <context> or <body> element is equal to “true”, the visible property of each child element of the composition is taken into account to define how each of these child element will be exhibited.

When the visible property associated with a <context> or <body> element is equal to “false”, all child elements of the composition are exhibited as hidden.

It should be remarked that an object with a visible property equal to “false”, that is, an object exhibited as hidden, may not have any of its content anchors selected while the visible property value persists as “false”.

When a document has its <body> element with its visible property set to “false” and its presentation event is in the paused state, the document is said to be in stand-by. In ISDB-T standard, when there is only one application in execution and this application is in stand-by, the service's main video is dimensioned to 100% of the screen, and the main audio is set to 100% of its volume.

A real number in the range [0,1] or a real number in the range [0,100] ending with the character “%” (e.g. “30%”).

The default value is “0%”.

“fill”, “hidden”, “meet”, “meetBest”, or “slice”.

The default value is “fill”.

Indicates how an object will be presented.

“fill”: scale the object's media content so that it touches all edges of the box defined by the object's “width” and “height” properties.

“hidden”: if the intrinsic “height” (“width”) of the media content is smaller than the “height” (“width”) property, the object must be rendered starting from the “top” (“left”) edge and have the remaining “height” (“width”) filled up with the background color; if the intrinsic “height” (“width”) of the media content is greater than the “height” (“width”) property, the object must be rendered starting from the top (left) edge until the height (width) defined in the property is reached; the part of the media content below (to right of) the height (width) is clipped.

“meet”: scale the visual media object while preserving its aspect ratio until its height or width is equal to the value specified by the “height” or “width” properties. The media content left-top corner is positioned at the top-left coordinates of the box; the empty space at the right or the bottom must be filled up with the background color.

“meetBest”: the semantic is identical to “meet”, except that the image is not scaled greater than 100% in either dimension. “slice”: scale the visual media content while preserving its aspect ratio until its height or width are equal to the value specified in the “height” and “width” properties and the defined presentation box is completely filled. Some parts of the content may get clipped. Overflow width is clipped from the right of the media object. Overflow height is clipped from the bottom of the media object.

The endProgress attribute specifies the amount of progress through the transition at which to end execution. The value of this attribute must be greater than or equal to the value of the startProgress attribute. If endProgress is equal to startProgress, then the transition remains at a fixed progress for the duration of the transition.

List of (type, subtype, dur, startProgress, endProgress, direction, fadeColor, horzRepeat, vertRepeat, borderWidth, borderColor) separated by semicolons where:

• Required type can be: “barWipe”, “irisWipe”, “clockWipe”, “snakeWipe”, or “fade”. For the complete list of the predefined transition types see: http://www.w3.org/TR/SMIL2/smil-transitions.html#TransitionEffects-Appendix.
• Required subtype values depend on the type values, as defined: “leftToRight” for “barWipe”, “rectangle” for “irisWipe”, “clockwiseTwelve” for “clockWipe”, “topLeftHorizontal” for “snakeWipe”, and “crossfade” for “fade”. For the complete list of the predefined transition subtypes see: http://www.w3.org/TR/SMIL2/smil-transitions.html#TransitionEffects-Appendix.
• dur attribute is specified according with one of the following syntax: (i) “Hours:Minutes:Seconds.Fraction”, where “Hours” is an integer in the [0,23] interval, “Minutes” is an integer in the [0,59] interval, “Minutes” is an integer in the [0,59] interval, and “Fraction” is a positive integer; (ii) Seconds“s”, where “Seconds” is a positive real number. The default value is “0s”.
• startProgress and endProgress are real number in the range [0,1].
• direction values are “forward” and “reverse”.
• fadeColor is “white”, “black”, “silver”, “gray”, “red”, “maroon”, fuchsia”, “purple”, “lime”, “green”, “yellow”, “olive”, “blue”, “navy”, “aqua”, or “teal”.
• horzRepeat and vertRepeat is a positive integer.
• borderWidth is a non-negative integer.
• borderColor is “white”, “black”, “silver”, “gray”, “red”, “maroon”, fuchsia”, “purple”, “lime”, “green”, “yellow”, “olive”, “blue”, “navy”, “aqua”, or “teal”.

The default value for the property is the empty string. If a transition type is specified then:

• “dur” default duration is “1s”,
• “startProgress” default value is 0,
• “endProgress” default value is 1,
• “direction” default value is “forward”,
• “fadeColor” default value is “black”,
• “horzRepeat” default value is 1,
• “vertRepeat” default value is 1,
• “borderWidth” default value is 0,
• “borderColor” default value is “black”.

The value of the transIn and transOut is a semicolon-separated list of transitions.

The purpose of the semicolon-separated list is to allow authors to specify a set of fallback transitions if the preferred transition is not available. The first transition in the list should be performed if the user-agent has implemented this transition. If this transition is not available, then the second transition in the list should be performed, and so on.

The type and subtype define the transition. The dur attribute specifies the duration of the transition.

The startProgress attribute specifies the amount of progress through the transition at which to begin execution. For instance, we can want to begin a crossfade with the destination image being already 30% faded in. For this case, startProgress would be 0.3.

The endProgress attribute specifies the amount of progress through the transition at which to end execution. The value of this attribute must be greater than or equal to the value of the startProgress attribute. If endProgress is equal to startProgress, then the transition remains at a fixed progress for the duration of the transition.

The direction attribute specifies the direction the transition will run. Note that not all transitions will have meaningful reverse interpretations. For instance, a crossfade is not a geometric transition, and therefore has no interpretation of reverse direction. Transitions that do not have a reverse interpretation should have the direction attribute ignored and the default value of “forward” assumed.

If the value of the type attribute is “fade” and the value of the subtype attribute is “fadeToColor” or “fadeFromColor”, then the fadeColor attribute specifies the ending or starting color of the fade. If the value of the type attribute is not “fade”, or the value of the subtype attribute is not “fadeToColor” or “fadeFromColor”, then the fadeColor attribute is ignored.

If the value of the type attribute is not “fade”, then the following attributes can be specified:

The horzRepeat attribute specifies how many times to perform the transition pattern along the horizontal axis.

The vertRepeat attribute specifies how many times to perform the transition pattern along the vertical axis.

The borderWidth attribute specifies the width of a generated border along a wipe edge.

The borderColor attribute specifies the content of the generated border along a wipe edge. If the value of this attribute is a color, then the generated border along the wipe or warp edge is filled with this color. If the value of this attribute is “blend”, then the generated border along the wipe blend is an additive blend (or blur) of the media sources.
