To enable consumers to seamlessly transfer content across a wide range of video endpoint products, Texas Instruments has introduced a new DaVinci technology digital media processor that can transcode video across multiple applications, including Media gateways, multipoint control devices, digital media adapters, video security surveillance DVRs, and IP set-top boxes. The new TMS320DM6467 DaVinci processor is a DSP-based system-on-a-chip (SoC) that is ideal for real-time multi-format high-definition (HD) video transcoding and comes complete with development tools and digital media software. The system solution integrates the ARM926EJ-S core with a 600 MHz C64x+TM DSP core and features a high-definition video coprocessor, conversion engine and target video port interface for up to H.264 HP@ L4 (1080p 30fps, 1080i 60fps, 720p 60fps) Synchronous multi-format HD encoding, decoding and transcoding is up to ten times better than previous generation processors.IdaRose Sylvester, senior research analyst at IDC, pointed out: "The demand for accessing video anywhere, anytime, on different devices is increasing, so applications must be able to manage local transcoding between different compression formats to support HD video. It satisfies the storage requirements of a large amount of data on different media, and supports sharing with other playback devices through different formats. The implementation of the above-mentioned requirements for high-definition technology requires further improvement of performance and expansion of storage capacity compared with many current systems. In addition, multi-format Transcoding technology also needs to be improved in the codec algorithm to ensure image quality."
Designed to meet the high-definition transcoding challenges of the commercial and consumer markets, the DM6467 delivers up to ten times better performance than previous generation digital media processors through its multi-core design. The DM6467 processor integrates ARM and DSP cores with HD video/image coprocessor (HD-VICP), video data conversion engine, and target video port interface. HD-VICP enables more than 3 GHz of DSP processing power through dedicated accelerators for HD 1080i H.264 high profile transcoding, while the video data conversion engine can also manage downscaling and chroma sampling. ) and video processing tasks such as menu overlay (menu overlay). A DSP core of less than 300 MHz can be used to manage multi-format video transcoding and reserve enough space to support other application performance. The DM6467 can meet the market requirements of media gateways and MCUs that require transcoding technology, but its flexibility and efficiency are also very attractive for applications that require high-definition encoding and decoding at the same time, such as video voice or video security. A market with high requirements for multi-channel SD encoding. The device's connectivity peripherals also include industry-standard PCI bus and Gigabit Ethernet.
The high level of integration and optimization of the DM6467 not only delivers the same high performance at a cost of only one-tenth the cost of previous generation applications, but also ensures the high flexibility required to meet multiple conference units (MCUs) and video. Requirements for multiple video formats for applications such as security monitoring. For example, when the previous MCU was processing HD video, each HD video channel required three 1GHz TMS320C6415T DSPs, and the cost per channel was $507. With a DM6467-based MCU, the system can be reduced to a single-chip HD solution, which reduces the cost per channel to $35.95. In addition, with the DM6467 handling video transcoding, the system can use low-power, low-cost DDR2 memory, which reduces the amount of flash and shrinks the FPGA, saving the system bill of materials (BOM).
Similarly, the video security monitoring system can also reduce the bill of materials through TI technology and achieve multi-format multi-channel encoding (up to 4 channels of MPEG4/H.264 MP D1, plus 4 sub-channels of MPEG4/H.264 MP) CIF) and decoding (up to 6 channels of MPEG4/H.264 MP D1) offer the flexibility to meet the requirements of hybrid digital video camera (DVR) and surveillance (DVS) systems. The DM6467 features an integrated C64x+ DSP for video analysis or proprietary video processing algorithms. The DM6467 integrates ARM9, 10/100/1000 EMAC and ATA interfaces, eliminating the need for an external host processor to support a single-chip DVR/DVS system.
The new DM6467 processor leverages TI's proven DaVinci development environment, including complete hardware and software and development tools. TI also introduced the corresponding DM6467 Digital Video Evaluation Board (DVEVM), which includes MontaVista Linux, industry standards and DaVinci application programming interfaces (APIs), DaVinci Codec Engine, and various multimedia codecs for evaluation. In addition to standard video, video, voice and audio codecs, the system includes a new transcoder that can transcode MPEG-2 to H.264. The DaVinci system dramatically simplifies the digital video implementation process, while TI's DSP third-party network offers more dedicated software and design expertise.
The TMS320DM6467 with DaVinci technology is now available to some customers and will be available in volume. The DVEVM will be available in the first quarter of 2008 and can be ordered through TI and its authorized distributors.
