Archived from the original PDF on Bytes 25—34 must contain sRGB standard values.
For 50 Hz systems, the DTV Monitor shall support an additional video format timing of Xp 50 Hz in at least one of two picture aspect ratios, 4: These values are the same as the values used in the Audio InfoFrame, which are shown in Table Detailed timing descriptors, in decreasing preference order. Several of the video format timings old and new cex available in two different picture aspect ratios.
Audio Format Codes Codes 0 1 2 3 4 5 6 7 8 The data applies to the audio associated with the next full frame of video data. This data block can be used to include information not specifically defined 861v this standard. Their discovery is handled somewhat differently than the previously defined formats due to the desire to reduce the number of bytes used to discover formats and at the same time maintain backward compatibility with and A.
For any of the compressed audio formats i.

The information in this section is now the controlling information on this extension and is considered normative. Secondary GTF supported, parameters as follows. Examples of the optional capabilities are support ce various audio and video formats included in this standard see Table 13 and Table Data Byte 5 contains information that tells the DTV Monitor how much the source device attenuated the audio during a down-mixing operation.
Speaker allocation information to support multi-channel LPCM audio. Display gamma, factory default range 1. Archived from the original on Timing Parameters for Xp There are two possible frame formats that differ only in 861h number of lines in the vertical blanking ces of the frame.

This implies that these formats will not be supported in implementations that do not also support reception of the AVI InfoFrame Version 2. Furthermore, content advisory user 681b, settings and blocking must be accommodated in the source device, and is beyond the scope of this standard. The first three bits are a Tag Code.
Advanced Timing and CEA/EIA-861B Timings
General, First Edition, The preferred format is the video format listed first in the EDID data structure. This Standard does not purport to address all safety problems associated with its use or all applicable regulatory requirements. Timing Parameters for Xp 50 Hz. This means that many graphics cards cannot express the native resolutions of the most common wide screen flat panel displays and liquid crystal display televisions.

This section was previously reserved for 8 byte timing 17 descriptors See  861bb is currently a reserved data block. The last five bits are a length field that designates the number of bytes in the data block associated with the tag. This format assumes the pixels are double clocked to meet minimum clock speed requirements for the interface. It can use either 4: There are some additional requirements related to this new information.
