Panasonic HD camcorder market H.264 SD card and insist on CCD-camera, H.264, HDTV-broadcasting industry

China Suppliers


Public support H.264 for HDTV Panasonic adhere to SD cards and CCD cameras reasons


Panasonic's HDTV camera market to support H.264


Matsushita Electric Industrial will be December 1, 2006 listed in the SD memory card can store HDTV images of the camera "HDC-SD1". New body weight about 430g, including rechargeable battery if the account is about 490g, is to support HDTV (1080/60i) the lightest models in the product.

  Video encoding used to use MPEG-4AVC/H.264 AVCHD specification. The new product is the second Sony HDR-UX1, HDR-SR1 and later to support the specification of a model. Recording time, when using 4GB SDHC, NN mode (bit rate 9Mbit / sec) under 1 hour, NE mode (bit rate 6Mbit / sec) under 1.5 hours.





Expected real price of new products, the Matsushita Electric Industrial intends to initially come standard with a capacity of 4GB, data transfer rate of 2Mbit / s over the SDHC memory card camcorder at 18 million yen. Plans for monthly sales in Japan the number is 2 million units. The model is "CEATECJAPAN 2006" Exhibits only case color has changed.





Selection of unique components The new models have been preliminary listed with Sony and Canon models 1080/60i support compared to the storage media and video devices are dramatic differences. New storage media used by other companies have not had the SDHC memory card. Matsushita Electric Industrial will also be listed on the storage media using DVD's, HDC-SD1's sister model "HDC-DX1", "DVD is now on the storage media, mainly in the cost sensitive overseas markets for the time being used. The long term or to use SDHC memory card-based "(the company).





SD memory card as the advantages, Matsushita cited as body parts can be reduced to the hard disk and DVD than when using less, so the vibration and high tolerance to dust, another camera can achieve a more compact body, and so on.





CMOS sensor with other companies to use the practice, the new product image sensor using CCD. On the ground that, after been put into practical application easier to get high-definition CCD. Matsushita Electric Industrial has been achieved despite a similar MOS sensor with the CMOS sensor, and actually used in mobile phones, but it seems not enough time on this basis to produce the MOS sensor used in camera.





Another reason is that the models for the use of three video components "3 Plate." 3 plate model even with data transfer speeds than the CMOS sensor in theory slower CCD, can get enough speed. 3 plate is Matsushita Electric Industrial has always insisted the approach. "Assuming the future use of the CMOS sensor or MOS sensor, also will continue to use the three plate" (the company). This is because the three plate spectroscopic accuracy (color resolution) high reason.





The other hand, there had three plate models of components in the HDTV support the cost of a larger installation problem, and Matsushita Electric Industrial in running the model, the "clamp and by improving the processing method to solve: Q this issue "(the company). The of the CCD's pixel pitch is 4.1 m, optical component size is 1 / 4 inch. Read mode for progressive scan (Progressive).





The models have the following characteristics.


With optical zoom, directional microphones are also substantial changes


Example, if I want to take the children to speak in the distance and the redeployed telephoto lens mode, greater than the wide-angle mode to record the voice of a child's voice. This is because the new product although cross (the user's left and right) can only increase the sensitivity of the direction of 8dB or so, but in the direction of camera (positive) on the sensitivity can be increased 20dB. This difference in sensitivity, through signal processing to suppress the voice from the horizontal direction to achieve. Signal processing parameters in accordance with the direction of the sound propagation time.





Support the High Profile H.264


"In the future, not Sony's existing products used in the main specification (MainProfile), but the high standard (HighProfile) will become mainstream H.264. This is because an increase in MainProfile in the 8 × 8 DCT and quantization matrix without increasing power consumption, etc. HighProfile can improve picture quality. The strengths of the film industry in the United States has been highly "(Matsushita Electric Industrial).





UniPhier developed using the H.264 codec LSI


New product by eliminating the AV equipment for the flat-mounted model of product-related functions in the play, which reduces power consumption. New product packaging is also smaller. In addition, HDC-SD1's power consumption, when the video is about 6W. Among them, the lens unit and the CCD consumes 2W, post image processing consumes 2W.





With more than 2.0 of the high refractive index refractive index glass


Using this high refractive index glass lens, single pieces of stamping and became non-spherical shape. The whole lens unit in the number of non-spherical surface to 4. Lens unit 13 constituted by the 10 groups, conducted in 21 surface coating treatment. 12 times optical zoom can be realized. If the maximum wide-angle lens angle conversion by 35mm film was 38.5mm, as the camera is quite broad in terms of the.





LCD display capability is improved And Panasonic SDTV previous models, the new products show the number of pixels to achieve its 2-fold, to 25 million pixels. Color reproduction range is 1.5 times.





With the PC using standard software for playback


Not remove the mosaic noise (Block Noise) when the frame speed, equipped with Pentium 4HT 3.0GHz ~ Pentium D 2.8GHz's PC for 30 frames / sec, equipped with Pentium III1.0GHz ~ Pentium 4 HT2.4GHz the PC for 2 / sec. The simple player with self-developed software for the Panasonic.





With authentication based on the remaining battery capacity display





New product with a product before Sony began with the in minutes remaining battery capacity display. This feature with Sony products, is the battery in the camera body on the basis of certification achieved. This certification is to prevent the use of alternative battery, compatible battery effect. "We are considering approval of the company's third-party products certified code" (Panasonic). [Key words]: Video camera   H.264   HDTV
