HDMI Module cecTalker



These days, 2K, 8K super high vision, and even audio devices can be connected to one another using HDMI terminals. However, developing an product with HDMI is difficult and has been a tough obstacle for many developers. In order to solve this problem, Socionext leveraged its sophisticated technologies and its wealth of experience in HDMI to offer an HDMI module cecTalker that simplifies the development of products with HDMI.
In particular, cecTalker allows these devices to be connected, which was previously difficult to do, by focusing on the CEC functionality defined in the HDMI standard and by connecting the devices using only the HDMI plug-in. cecTalker expands the possibilities of medical, monitoring, and broadcasting equipment, as well as video and audio equipment, depending on how you want to use them.
cecTalker also allows customers to create prototypes by connecting to a PC,
Raspberry Pi*1, Arduino*2, or SPRESENSE™*3 and to perform other design work on platforms that they are familiar with.

cecTalker has two models: HDMI selector type model [Black] and V-by-One converter model [White]. These models not only simplify the development, evaluation, and testing work performed by customers, but they also allow customers to incorporate them into their products and mass produce them.
Devices connected with HDMI cables can also be integrated using CEC.
