As technology advances and the popularity of audio-visual products increases, many consumers will purchase various types of audio-visual products for a better entertainment experience. One example would be turning their living room into a home theater so they can enjoy a high-quality audio-visual experience at home. The soundbar, an affordable, easy-to-install product has become one of the most accessible home theater audio accessories. However, when using CEC function, consumers may potentially encounter connection issues between the soundbar and the TV or the STB. CEC One Touch Play can bring all sorts of issues during usage.
HDMI CEC, A Double-edged Sword
HDMI technology is often used for audio-visual products. The Consumer Electronic Control (CEC) function allows users to minimize the number of remote controllers from various brands. CEC function allows users to control HDMI devices that are connected to the same audio-visual ecosystem. In theory, this function greatly improves the user experience, but Allion’s home audio-visual consulting team has found that this function is very troublesome for every manufacturer.
Let’s imagine a simple CEC One Touch Play scenario for the average user. When the user wants to turn on the soundbar by pressing the on button on the soundbar remote, they expect the TV to turn on simultaneously. However, the TV that is connected to the same ecosystem does not have any response.
Does this mean CEC One Touch Play can malfunction?

The manufacturer that received this customer complaint immediately contacted Allion, hoping to get to the bottom of this problem. After getting a good understanding of the whole situation, Allion’s professional consulting team first use the protocol CEC communication analyzer to get a further understanding of the CEC issue. Our team immediately found the problem to be the TV. The specific model did not conform to CEC standards, causing the TV to have no response when the soundbar was turned on.
