Overview:
Today’s professional studio-quality video broadcasting equipment based on IP communication must have the capability to decode either MPEG-2 MP@HL or MPEG-4 AVC (H.264) and in real time transmit the decoded signal to an HD display for viewing or monitoring. The DaVinci™ TMS320DM6467 SoC solution from Texas Instruments can provide this performance along with many other benefits.
High Performance and Flexibility:
DaVinci™ TMS320DM6467 digital media processors are designed to support the high-throughput, multiple-application requirements of video systems. The programmable DM6467 processor supplies a high level of performance for handling real-time audio-video codec algorithms. The DM6467 processor can be programmed to support any number of audio and video standards and can be updated easily as network configurations and service needs change. Software partitioning into mathematically-intensive signal processing on the DSP and video accelerators, and control operations on the ARM® provides performance headroom for emerging applications.
System-on-a-chip (SoC) and Cost Savings:
SoC integration combines the DSP with high definition (HD) video and imaging coprocessors to provide the high-speed computation required for HD video encoding and decoding, plus an ARM926 RISC processor for user interfaces, system control and programming ease. The DM6467 also integrates many of the external components required for digital video including 10/100/1000 BaseT Ethernet MAC, video scaler, chroma conversion hardware, standard PCI bus, and a high-speed memory subsystem that includes a two-level cache, interfaces to external memory and storage, and enhanced direct memory access (EDMA) control.
Quick Time to Market:
In addition to the processors, DaVinci™ technology also provides foundation software, algorithms and application program interfaces (APIs) that simplify video system development.
High-Power PoE:
With the combination of Texas Instruments’ powered device controllers and current mode PWM controllers, providing power to video systems with greater power requirements than those specified by the IEEE 802.3af standard (i.e. greater than 13W) can be easily achieved.
