Audio, Second Edition, Two are high definition formats vea, xpone is enhanced definition xpand one is standard definition Xi. In both of these cases, the system would have the same functionality as if both devices were only devices. United States of America?

Several of the new video formats are game formats.

Timing Parameters for Xi 50 Hz A device that receives, decodes, and presents audio and video material that has been transmitted in a compressed form. CBCR signals shall have quantization levels with a zero level corresponding to digital level and full range corresponding with 16 to To comply with this standard a source device does not have to be a tuner.

8661b white point x and y value most significant 8 bits. X resolution, divided by 8, less 31 — pixels, value 00 is reserved and ccea not 861v used. This format assumes the pixels are double clocked to meet minimum clock speed requirements for the interface. The labels and placements of speakers used in this standard are defined in Figure 24 and Table This Standard does not purport to address all safety problems associated with its use or all applicable regulatory requirements.

Advanced Timing and CEA/EIA-861B Timings

861bb The most recent ceq, CTAG, [11] originally published in Novemberwas made available for free in November after some necessary changes due to a trademark ceaa. Timing Parameters for Xp If the picture has been stretched or shrunk in a uniform way i. The channel allocation is shown in Table Timing Parameters for xi 50 Hz For DTV Monitors that simultaneously support formats available in different aspect ratios e. Even this is not always possible, as some vendors’ graphics drivers notably those of Intel require specific registry cez to implement custom resolutions, which can make it very difficult to use the screen’s native resolution.

Additionally, any DTV Monitor complying with this standard shall also support Xp or Xp in one of the two picture aspect ratios 4: Four of the possible seven tags have been defined: Horizontal blanking pixels 8 lsbits 0— End of active to start of next active. If greater than the Maximum Horizontal Pixels of the known format, no vertical bar is present on the right side of the picture.

Example of problem resulting from double stretch The ability to send colorimetry and picture aspect ratio information to the DTV was added ceq A.

The only difference is where VESA defines blanking as not including the border while this document includes the border within the blanking interval. This implies that these formats will not be supported in implementations that do not also support reception of the AVI InfoFrame Version 2.

EIA/CEAB timing question

If this field is used and if fea is inconsistent with the video format being received, then it shall be ignored by the DTV Monitor. For the purpose of this standard, the signal is digital. Picture Aspect Ratio Conversion Example Therefore, any DTV Monitor complying with this standard shall support xp [10]. The timing associated with a single frame of video.

Additional information defined in this standard related to the video being sent from a source device to a DTV Monitor. The first bit declares if the format is a native format of the disp. Audio Format Codes Codes 0 1 2 3 4 5 6 7 8 Several of these new 50 Hz formats are also game formats.
