Renesas adds muscle to car information device platform

Renesas Electronics Corp. has developed a terrestrial digital broadcast reception middleware that supports the Integrated Service Digital Broadcasting-Terrestrial (ISDB-T) standard for platform solutions of automotive information systems. The middleware claims to efficiently control the video image processing (synthesis, enlarge/reduce, IP conversion and other functions) hardware included in the R-Car H2 and R-Car M2 using dedicated drivers.

The middleware offers optimization so that the maximum performance of the SoC device is acquired. It also allows terrestrial digital broadcast viewing systems to be implemented without complex hardware control by the user system.

The middleware includes the powerful error tolerance functions required in automotive information devices. In particular, it provides both fade processing for audio noise reduction and video complementation processing using concealing processing to supplement missing data so that it can output as smooth audio and video as possible even in cases where TV broadcast reception conditions are poor. This can contribute to achieving smooth television viewing even when reception conditions are degraded during vehicle motion.

It is now desired to be able to construct systems that operate stably even in the high-load environments associated with the increasingly high functionality of multimedia functions such as two-screen output and running multiple applications at the same time. To respond to these sorts of needs, this product contributes to the implementation of stable terrestrial digital broadcast viewing systems by implementing control flows that multiplex and manage bus bandwidth for both the video and audio data as well as the instruction data that controls the hardware.

Furthermore, the middleware implements a control flow that excludes, to the greatest extent possible, compression processing that could degrade video image quality to respond to desires for performance with respect to increased image quality video. Thus this product makes it possible to develop products that support a wide range of usage scenarios by having the user system dynamically select from these control flows.

In addition, the middleware supports a content copyright dedicated protection system (ARIB: Part 3 of the STD-B25 standard) standard that does not use an IC card (the B-CAS card), and thus contributes to flexible user system development that does not use only the earlier copyright system (which requires a B-CAS card).

Samples of the middleware are scheduled to be available in December 2013. (Availability is subject to change without notice.)
