Ovid Video has launched the AVST_EVM6467ZUT7, a 1080P HD video development platform based on H.264, and the AVST_EVM6467ZUT7-Plus, a development platform that further supports 4-Ch D1 multi-channel video. The above platforms are based on TI's DaVinciTM family of high-end processors TMS320DM6467ZUT7, including A high-performance DSP core that can run at 729MHz, an ARM926EJ-S core that can run at 364.5MHz and HDVICP HD video coprocessor. The DM6467ZUT7 can support up to 1920×1080I60/1920×1080P30 resolution H.264 HD. Video encoding/decoding function.

"Codec is still one of the core competencies of HD video systems. For this reason, we have carefully produced DSP image libraries including AAC-LC/HE and H.264-HP codec algorithms, which customers can immediately use the AVST_EVM6467ZUT7 development platform. The DVTB component evaluates the H.264 HD video codec algorithm supported by the processor," said Touse Hou, manager of Ovid's software division.
The AVST_EVM6467ZUT7 incorporates many original designs to help customers quickly launch 1080P HD video products. The hardware system uses eight stacked PCB designs to ensure signal integrity (SI) and power integrity (PI). Reduced sheet costs.
"Because the DaVinciTM family of processors are powered by low-voltage multi-supply, DDR2 low-voltage high-speed memory is used as the main memory, especially the high-performance processor of DM6467ZUT7 requires a video ADC sampling clock of up to 148.5MHz in 1080P format, in UXGA format. It is 162MHz, so we must carefully design the power system and distribute the board stacking reasonably to ensure the ripple of the whole system. The power-on sequence and power supply current can meet the requirements of high-definition video system.†Chen Wei, Manager of Aowei Video Platform Mr. Lemon said.
In the selection of Flash, AVST chose SLC flash chip with higher reliability and fewer bad blocks, and it is easier to purchase and solder TSSOP package as BootROM, which can meet the reliability requirements and consumer applications of industrial applications. The need for cost.
After extensive market research, AVST adopted a TI high-performance HD video AD chip TVP7002, an ADI high-performance HD/SD video DA chip ADV7343, canceled the YPbPr RCA interface, and replaced it with 2 DB15 Stack connections. In terms of SD video input, a TI TVP5147 high-performance Video Decoder chip is used.
"We actually weakened the function of SD video, because the encoding and decoding of HD video is the biggest highlight of the DM6467 processor, but considering that customers may need to expand the SD interface on the panel of the product, we have incorporated in the design. The TVP5147 chip is extended by a 2×5 DIP connector. The DB15 connector is considered to be a large part of the customer's HD video input source is a desktop or projector from the VGA interface, DB15 connection At the same time, the VGA interface and the YPbPr interface can be used to cover a larger customer base," said Lemon Chan.
Supporting Gigabit Ethernet is another highlight of the DM6467 processor. Since the compressed video code rate will be between 4Mbps and 20Mbps, the 100M network is insufficient for high-definition video network transmission, especially for some. Quality image quality occasions, such as medical systems, radio and television systems, court systems, etc.
“We replaced the network chip that TI used in the reference design because it was difficult to meet the volume production requirements both in terms of price and delivery time, and the driver was redesigned with HanRun’s Gigabit Ethernet connector. It's easy to buy chips and connectors without waiting for months," said Lemon Chan.
AVST's solution also adds many common interfaces to the design, including 2 RS232 interfaces, 1 USB interface, two-color LED indicator, infrared signal receiving tube, etc. The most distinctive feature is that this solution also supports 2.5-inch SATA high-speed hard drive expansion interface.
Mr. Chen Lemon said: "For products like Streaming-Box, storage devices may not be needed very much, but for some applications with higher security levels, we can't guarantee the stability of the network around the clock, so it needs to be done in embedded terminals. Local storage, and flash-based solutions are difficult to meet the demand for high-definition video for high-capacity storage devices. The 2.5-inch SATA interface high-speed hard disk is the most suitable choice in terms of power consumption, cost and capacity."
AVST also introduced the AVST_EVM6467ZUT7-Plus development platform for HD video and multi-channel CIF/D1 video applications, which can support 4 channels of D1 H.264 multi-channel video compression or 1 channel 1080I60/1080P30 H.264 compression.
AVST_EVM6467ZUT7-Plus supports a wide range of audio and video expansion interface standards, and can support multi-channel video (4-Ch D1, 8-ChIF, 8-Ch Half) by supporting TI's most advanced multi-channel video decoding chip TVP5158 through an expansion interface. -D1, 8-Ch CIF plus 1-Ch D1) DVR/NVR system.
At present, the AVST_EVM 6467ZUT7 has been fully available, and the AVST_EVM6467ZUT7-Plus has begun to accept orders.
