Reliable Bdz-s77 Blu-ray Recorder by Sony

Blu-ray disk format is the extended next version of the optical disk format. The main idea behind the blu-ray format was to develop a format that could rewrite, playback and record HD video with large capacity to hold the data. Blu-ray disk can hold data greater than 5 times than that of the DVD (Digital Versatile Disk). 25GB of data can be held by the single layer and 50GB data by dual layer blu-ray disk.

Blu-ray format also provides support to the multi layered disks therefore this disk format can be extended easily. And the recording capacity can be enhanced by the addition of layer to the blu-ray disks. High definition video of more than nine hours and standard definition video of about twenty three hours can be recorded on disk of 50GB.

If we take a look at the specification of the blu-ray disk, 36MB/sec is defined as speed of 1x. Blu-ray has the adopted larger NA (numerical aperture) that is why it has potential to increase and hence achieve higher speeds. The meaning of large value of NA is that the blu-ray requires less power for recording and lower speed of the disk rotation than the HD-DVD & DVD to achieve similar data speed.

The Sony’s BDZ-S77 blu-ray recorder has BS digital T.V tuner. This tuner is built-in and helps the recorder to record programs of 2 hours in both 720p & 1080i. The potential abilities of projectors and plasma panels remain unused due to the DVD video format’s limitations of frame size. The DVD disk’s frame size is limited by capacity and bit rate of the Digital Versatile Video Disk. Blu-ray media is the base of the Sony BDZ-S77 recorder that is developed to bring HD experience to the consumer houses and to increase the numbers of consumers. For digital satellite T.V, the Sony blu-ray recorder has built-in broadcasting satellite tuner (BS). Besides the two hours video of high quality, the user can also record from satellite broadcasting the AAC 5.1 MPEG-2 sound. Single layered blu-ray DVD disk can contain data of 25GB.

If we compare the blu-ray format with the DVD video media, the difference among them is the laser type. Blue laser (405nm wavelength) is used by blu-ray format and red laser by the media of DVD video. The aperture of lens is 0.85 and 36 MB/s is the bit rate (service data included). The diameter of the blu-ray disk is 120mm which is equal to that of DVD & CD. The thickness of disk is 1.2mm and 0.1mm protective layer. Phase transition is the recording mechanism. The high processing, reading speed and capacity enables the data speed to reach up to 36MB/sec on disk (single layer) at reading speed of 1x. In signal recording of satellite T.V in High Definition T.V standard, it can hold video (1024i) of approx. two hours. In the absence of multi-channel sound and lower bit rates, a single blu-ray disk can house six or twelve hours in modes of LR and SR.

The Sony blu-ray player supports the reading of DVD-RW DVD-Video DVD-R CD-RW CD-R and CD. The reduction technology of block and frame noise helps to obtain image of high quality. This technology analyzes the image and adjusts to it dynamically. Good enough image makes the system to do little work. Dual Motion Adaptive Interlaced Picture Converter DMAIPC mechanism detects the interlacing automatically both from BS input (analog) and in recording. If necessary, it helps to convert it to progressive scanning. The front panel of the Sony BDZ-S77 blu-ray recorder goes down smoothly and reveals the controls and tray.

I am looking for a software that searches stocks, where the 20-50 day EMA lines are locked together.?

I have tried Yahoo Finance stock search analyzer, but did not know what to look for. The exponential moving averages lines could be locked together for 1 to 2 or more days at a time, before a breakout one way or the other. Thanks. Ray L.

this is a freebie, also you can add many other indicators to the 2nd and 3rd boxes.

If you want to get software that will sing and dance, slice and dice and be able to download fundamentals to XL for additional manipulation, I highly reocommend Telechart by the Worden brothers. Take one of their free all day seminars. They won't pressure you into subscribing, but for the price of a soda per day you'll be lightyears ahead of 80% of the stock investors.
