电子发烧友 电子技术论坛 EIA STANDARD EIA/CEAB A DTV Profile for Uncompressed. Advanced Timing and CEA/EIAB Timings. NOTE: To use the Advanced Timing page, you must be an advanced user and familiar with the concepts of. The newly adopted EIA/CEAB (B) standard defines protocols for sending DTV signals over an uncompressed digital video interface.

In many cases, the DTV Monitor will be able to determine the video format from the video itself. Week numbering is not consistent between manufacturers.
The packets and bits are defined ceea. Control of closed captioning settings, programs, events, etc. There are three possible frame formats that differ only in the number of lines in the vertical blanking interval of the frame. General Format of InfoPacket Additionally, all formats defined in this standard including the and A formats shall be listed The 8-byte descriptors do not support the DTV formats defined in this standard since they are not compliant with VESA GTF .
MB 0 contains the least significant byte while MB 3 contains the most significant ceea. Several systems are being developed to take advantage of these enhancements1.
Consistent with other applications, it is not necessary to enumerate X since that format is required to be supported in all cases. Timing parameters for xi ITU  ITU  Future other values Table 10 illustrates the terminology and examples of common aspect ratio information that can be communicated from a source device to a display device using this standard. The mandatory ceea optional formats defined in this standard shall comply with the timing parameters in Table 4 and the timing diagrams that follow.
Additionally, six new 60 Hz format timings have been added in this standard B. Therefore, only non-critical information should be placed in block 2 and up. For the x format, there may be video at these levels; 86b is recommended that the full range be displayed for this format. Version 3 cfa includes four new optional types of data blocks: Simultaneous support of formats available in two different aspect ratios shall be indicated by listing both formats in the EDID data 861g at the same time.
The labels and placements of speakers used in this standard are defined in Figure 24 and Table This implies that these formats will not be supported in implementations that do not also support reception of the AVI InfoFrame Version 2. The effects on the EDID data structure as well as backward compatibility to devices are explained in Section 7. FR0 can be used to designate whether a field is a repeated field or not.
Exact parameters are determined by the interface specification used with this standard e.
Ver 1 Single AR support etc. The general structure is shown in Annex G. The ability to designate in what colorimetry the picture should be displayed and information on the active format were also included.

Additional information defined in this standard related to the video being sent from a source device to a DTV Monitor. Even this is not always possible, as some vendors’ graphics drivers notably those of Intel require specific registry hacks ccea implement custom resolutions, which can make it very difficult to use the screen’s native resolution.
There are two versions of Short Audio Descriptors. This format is unique in that, depending upon the pixel repetition factor specified in the AVI InfoFrame, this format can represent any of the following typical formats: The digital representation shall be as defined in Part 1, Section 6. Horizontal screen size, in 861v range The source device then chooses its output format, taking into account the format of the original video stream and the formats supported by the DTV Monitor. Although there may be more than one native format, the one most preferred by the DTV Monitor is listed first.
This 81b B specifies new requirements for the use of this timing extension see Section 7. For 60 Hz formats, the display will respond automatically to either 60 Hz or A video monitor capable of displaying xp in Data Csa 4 contains a Video Identification Code.
The last 861g extension may contain less than six byte descriptors. The timing associated with a single frame of video. In both of these cases, the system would have the same functionality as if both devices were only devices.
There can be up to 32 bytes following any tag, therefore there may be up to 10 Short Audio Descriptors in the Audio Data Block. Secondary GTF supported, parameters as follows.
Extended Display Identification Data
All of the formats listed in Table 3 are new and are optional. Timing parameters for xi 50 Hz The EDID data structure includes manufacturer name and 86b number, product type, phosphor or filter type, timings supported by the display, display size, luminance data and for digital displays only pixel mapping data.
This would be the picture aspect ratio that would be displayed if a DTV Monitor were to receive a Video Format Timing with no accompanying picture aspect ratio information i. Timing Parameters for Xi A device that receives, decodes, and presents audio and video material that has been transmitted in a compressed form.
This structure first appeared in A.
