Image of product development using "cecTalker"
The HDMI module cecTalker(pronounced “C-E-C-Talker”) enables the user to easily design UI and UX for devices in order to make them convenient just by connecting with HDMI. cecTalker makes it easy to design a high-speed interface for video and audio, strongly supporting customers' development work.
These days, video and audio devices for 2K and even up to 8K Super Hi-Vision can be connected to one another using a single cable via 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 technological capabilities 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 SPRESENSETM*3 and to perform other development work on platforms that they are familiar with.
First, let's try using cecTalker in various ways. For example, try creating an app by connecting a PC and an AV device, or creating a convenient device by combining with Raspberry Pi, and so on.
When you have determined the concept, try creating a prototype by designing the exterior or customizing the cecTalker board to fit the exterior.
After checking the prototype, start mass production by putting the cecTalker in the assembly process at the factory. The cecTalker can also be certified, so it is safe to use as it is.
Product line-up
Overview
cecTalker has two models: HDMI model [Black] and V-by-One 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.
