Question
Your customer reports that new A/V equipment that plays movies cannot be displayed on their Cisco TelePresence endpoints. This A/V equipment is connected to the Cisco TelePresence codec via an HDMI cable. However, older A/V gear that uses composite cables is able to display content. What is most likely the cause of this issue?

- B. TIP (TelePresence Interoperability Protocol) governs video conferencing session negotiation between endpoints and is unrelated to local HDMI content playback from an A/V source.
- D. Operating system compatibility is irrelevant to HDMI signal passthrough; the codec processes the digital video signal directly and does not interact with the source device's operating system.
