Devices using this standard are expected to

Devices using this standard are expected to disregard header values, and payloads that follow said header values, for which no definition known to that unit exists.

24、 data waveform is described in Section 4.1 for h (480i) or Section 4.2 for 2h (480p) for signals compliant with CEA-770.2 for Type A packets and Type B packets. Type A packets are the same as those in EIA/CEA-805. Type B packets were newly defined in CEA-805-A. Section 4.3 describes the data wavefor
25、m for HDTV (1080i and 720p) signals compliant with CEA-770.3 for Type A and Type B packets. Section 4.4 defines use of the header values. Section 4.5 defines the data payload for Type A and Type B packets. Use of Type A packets in source devices is deprecated. 4.1 Waveform for Standard Definition In
26、terlaced Signals The data waveform for 480i signals shall be as defined in CEA-770.2 Section 8.1. 4.1.1 Aspect Ratio Signaling for Standard Definition Interlaced Signals The standard method for signaling 16:9 aspect ratio in a 480i signal shall be via IEC 61880. Sink devices compliant with this stan
27、dard shall tolerate IEC 61880 signals or other signals on line 20 and line 283. Sink devices should recognize that waveforms other than IEC 61880 may be present on line 20 and line 283. Sink devices compliant with this standard shall default to 4:3 output format in the absence of an IEC 61880 signal
28、 on line 20 and line 283. Other signals may be transmitted on line 20 and line 283 as described in CEA 2020. IEC 61880 is typically used to signal CGMS-A and APS in addition to aspect ratio and display format. CGMS-A and APS are also signaled in CEA-608. In order to avoid ambiguity when both means o
29、f signaling CGMS-A and APS are present, source devices should ensure that both IEC 61880 and CEA-608 carry the same, proper CGMS-A and APS signals. NOTEConditions for applying the CGMS-A and APS bits in source devices may be bound by private agreements or government regulations. Also, required behav
30、ior of sink devices detecting the CGMS-A and APS bits may be bound by private agreements or government regulations. Implementers are cautioned to read and understand all applicable agreements and regulations. CEA-805-E 4 4.2 Waveform for Standard Definition Progressive Signals The data waveform for
