Bitmap defined in Table detailing the video frame skipping support with its parameter and frame rate change support. This bitmap is also used by the wfd-video-formats parameter specified in section 6. The frame rate described in Table , Table and Table refer to the rate at which video payload is sourced from the WFD Source. The transport stream may include information that is used to determine if the video payload corresponds to 60 The decoder at. Page 69 of See section 3.

When specifying support for VESA format, the WFD Sink shall indicate support for a resolution with higher refresh rate s if and only if it also indicates support for a corresponding lower refresh rate. For instance, support for xp60 can be indicated only if support for xp30 is also indicated. Page 70 of Page 71 of The Profiles Bitmap when included in a WFD subelement shall either have B0 or B1 but not both of the bitmap set to one This bitmap is also used by the wfd-video-formats parameter specified in section 6.

Page 72 of In this case, the bitmap represents either:. Page 73 of If this bitmap is used in an RTSP message and the minimum-slice-size field in the wfd-video-formats parameter or the wfd-3d-formats parameter is all zeros, all bits in this bitmap shall be set to zero. The subfields [B9:B0] and [BB10] shall be set to a non-zero value in other cases.

If Video Frame Skipping is supported, the maximum time intervals in unit of 0. This bitmap is also used by the wfdvideo-formats parameter specified in section 6. Page 74 of This bitmap is used by the wfd-3d-video-format parameter specified in section 6. Frame rate described in the Table , refer to the rate at which video payload is sourced from the WFD Source.

The decoder at the WFD Sink shall have support for Page 75 of Page 76 of If the WFD Sink does not support this field, it shall set this field to all zeros. Otherwise the WFD Sink shall set this field to a besteffort estimate of the worst-case time between the availability of source data at the input interface of the decoder, and the presentation of the corresponding decoded data at the input interface of the rendering device, rounded up to the next higher multiple of 5 msec.

This field should be set to all zeros when transmitted by the WFD Source in. Page 77 of This bitmap is also used in the modes field of wfd-audio-codecs as described in section 6. Interpretation Sampling Frequency kHz.

Interpretation Bits. A device is deemed audio rendering capable if it can playback audio payload with or without the help of an external transducer e. Page 78 of The format of the Content Protection subelement is as shown in Table Table : Content Protection Subelement. Page 79 of Bitmap defined in Table detailing capabilities for miscellaneous and optional functions.

Table depicts the format of this subelement. Page 80 of The WFD Device that is acting as a GO based on P2P connection already knows about all its clients, and it can advertise the known information for other clients of the group to other WFD Devices that are not part of the group. Note that this subelement shall not include GO itself. Field Name.

If the WFD Device described in this descriptor is not associated with the infrastructure AP, these 6 octets shall be set to all zeros. How to choose one is out-ofscope of this Specification, but it is recommended to choose one that can be used in TDLS topology. Page 81 of If the WFD Device described in this descriptor is not Coupled, these seven octets shall be set to all zeros. The recipient shall interpret these bits as WFD Session availability unknown. Page 82 of Field in the Frame Page 83 of Corresponds to the Management Frame subtype as defined in [13].

Page 90 of Page 91 of This chapter defines the methods and messages that are used to establish, maintain, manage and teardown WFD Sessions. The wfd-audio-codecs parameter specifies the audio formats supported in the WFD Session. Valid audio codecs are listed in section 3. Page 92 of The wfd-video-formats parameter specifies the supported video resolutions Table , Table , Table , H.

Valid H. Page 93 of In this case, level indicates the maximum level support for the specified profile.

Install Helm

The H. In this case level refers to the actual level to be used with the selected profile. A WFD Sink sets the min-slice-size value to the smallest slice size it can decode. Slices smaller than the min-slice-size value may not reduce latency. A WFD Source sets this value to the smallest encoded slice it may transmit. The min-slice-size field is expressed in number of macroblocks.

The wfd-3d-formats parameter specifies the support for stereoscopic video capabilities. Valid 3D stereoscopic configurations supported in this Specification are listed in Table Page 94 of If content protection is not supported or is not currently possible for any reason, the parameter is set to none. If content protection is supported, the parameter is set to HDCP2. The port number shall be between 1 and The wfd-display-edid parameter specifies the EDID of the display on which the content will be rendered.

EDID data comes in multiples of byte blocks as shown in Figure Refer section 5. Page 95 of A WFD Sink that supports the wfd-display-edid parameter shall include the entire EDID data structure that is available from the display device in a edid-payload field with indicating its length by a edidcount field in a unit of a number of bytes block s.

A WFD Sink that does not support wfddisplay-edid parameter shall set the edid field of the wfd-display-edid parameter to none, except for a WFD Sink dongle without an integrated display or with an integrated display that is not being used to render streamed video. The WFD Sink dongle without an integrated display or with an integrated display that is not being used to render streamed video shall not set the edid field of the wfd-display-edid parameter to none regardless of whether an external display device is attached or not.

If EDID data is not available at the WFD Sink dongle without an integrated display or with an integrated display that is not being used to render streamed video, the edid-block-count field shall be set to 0x00 00 and the edid-payload field shall be none, instead of EDID data. Page 96 of If EDID data is available at the WFD Sink dongle without an integrated display or with an integrated display that is not being used to render streamed video, the edid-block-count field and the edidpayload field shall be set to include entire EDID structure.

In this case, The WFD Sink dongle without an integrated display or with an integrated display that is not being used to render streamed video should pass the EDID blocks from the connected external display device to the WFD Source as is, regardless of checksum failure and other error conditions.

Otherwise, edid-payload contains the entire EDID data structure available from the display device. Length of edid-payload shall be a multiple of bytes. Page 97 of Type of sink s. Other combinations are reserved. Table : wfd-url0 and wfd-url1 values in wfd-presentation-url.

Protocol Evolution and its Impact on Network Operators

Other profiles described at other sections in [6] are not relevant to this Specification. Page 98 of Table : wfd-client-rtp-ports parameter values in M3 response message When a WFD Source sends a RTSP M4 request message that includes the wfd-client-rtp-ports parameter as a part of WFD Capability Negotiation, the rtp-port0 and rtp-port1 values in the wfdclient-rtp-ports parameter shall be set as shown in Table Audio and video session, audio-only or video-only session.

WFD Source streams corresponding content to rtpport0.

Page 99 of Support of the wfd-preferred-display-mode parameter is optional. Otherwise: the proposed wfd-preferred-display-mode is not acceptable to the WFD Sink.

Transmission Control Protocol (TCP) Parameters

The following flow diagram illustrates the messages exchange that includes a preferred-displaymode-supported field and wfd-preferred-display-mode parameter. Page of This is the pixel depth of the display output which is different from the codec pixel depth. Only one bit is set by the WFD Source to indicate the selected mode. More than one bit can be set by the WFD Sink to indicate its capabilities. Specifies the 2D and stereoscopic 3D display modes.

This mechanism allows 0 or 1 active connector to be reported by the WFD Sink. Handling of multiple connector types simultaneously is implementation specific and is out of the scope of this Specification. The WFD Sink dongle that is not connected to an external display and it is not acting as a WFD Sink with embedded display to render streamed content shall return a value of "none". Reserved Indicates a type of physical connector that is not listed from value 0 to Table : Display Connector Type field.

Specification - Canon Europe

If the value as connector-type is reported from the WFD Sink, WFD Sources may not be able to unambiguously identify the connector type that is in use. See underneath Table for detail. This does not correspond to a stream as per usual RTSP convention, but instead is used to indicate that the request is for the capabilities of the WFD Sink. A WFD Sink shall use the wfd-presentation-url value see section 6. A WFD Device shall use the tag org.
