Member since: Aug Blu-ray reviews: 5. Streaming services should all have ads. People still want online stuff to be free and ads is the way that works. I’ve heard the steaming version has crushed blacks to go with the over compressed soundtrack. Nice, I can wait. It could be good or bad but I’m going to at least see a well produced version of it.

But anyway, continued growth for the HBO brand however one slices it. Originally Posted by JakeTaylor7. Member since: Jan I’m kind of hoping there will be more exciting free sites like Tubi. But even with those I often find myself gravitating to Tubi and the free sections from platforms like Vudu and YT. Ads are generally fine with me as it gives me time to decompress for a second and surf the web for a minute or two. Redbox and Roku have ad based streaming like Tubi.

Probably all the same stuff too. Originally Posted by meremortal. Thanks given by: meremortal Rouhana Jr. Trading Score: 8. All times are GMT. The time now is PM. Archive – Top. United States.

In the fourth photo, the inside of the optics package can be seen. Note that since this is a CD-ROM drive, there is only one laser, which is the black component mounted to the bottom left of the assembly.

Just above the laser are the first focusing lens and prism that direct the beam at the disc. The tall, thin object in the center is a half-silvered mirror that splits the laser beam in multiple directions. To the bottom right of the mirror is the main photodiode that senses the beam reflected off the disc. Above the main photodiode is a second photodiode that is used to sense and regulate the power of the laser. The irregular orange material is flexible etched copper foil supported by thin sheet plastic; these are ” flexible circuits ” that connect everything to the electronics which is not shown.

The first laser disc, demonstrated in , was the Laservision inch video disc. The video signal was stored as an analog format like a video cassette. The first digitally recorded optical disc was a 5-inch audio compact disc CD in a read-only format created by Sony and Philips in Also in , Sony introduced a LaserDisc data storage format, with a larger data capacity of 3.

In September , Sony announced the MiniDisc format, which was supposed to combine the audio clarity of CD’s and the convenience of a cassette size. The first Blu-ray prototype was unveiled by Sony in October , [65] and the first commercial recording device was released to market on April 10, Technically Blu-ray Disc also required a thinner layer for the narrower beam and shorter wavelength ‘blue’ laser.

Excluding an optical drive allows for circuit boards in laptops to be larger and less dense, requiring less layers, reducing production costs while also reducing weight and thickness, or for batteries to be larger.

However, new optical disc drives are still as of available for purchase. Most optical drives are backward compatible with their ancestors up to CD, although this is not required by standards.

Compared to a CD’s 1. This allows a DVD drive to focus the beam on a smaller spot size and to read smaller pits. With the newer Blu-ray Disc drives, the laser only has to penetrate 0.

Thus the optical assembly would normally have to have an even greater focus range. During the times of CD writer drives, they are often marked with three different speed ratings. In these cases, the first speed is for write-once R operations, the second speed for re-write RW operations, and the last speed for read-only ROM operations.

For DVD writer drives, Blu-ray Disc combo drives, and Blu-ray Disc writer drives, the writing and reading speed of their respective optical media are specified in its retail box, user’s manual, or bundled brochures or pamphlets. The recorder, should it run short, would be forced to halt the recording process, leaving a truncated track that usually renders the disc useless. These can suspend and resume the recording process in such a way that the gap the stoppage produces can be dealt with by the error-correcting logic built into CD players and CD-ROM drives.

The first of these drives [ which? At that time however, no recordable DVD media supported that high recording speed yet. Although later interfaces were able to stream data at the required speed, many drives now write in a ‘ zoned constant linear velocity ‘ “Z-CLV”.

This means that the drive has to temporarily suspend the write operation while it changes speed and then recommence it once the new speed is attained. This is handled in the same manner as a buffer underrun. CD recording on personal computers was originally a batch-oriented task in that it required specialised authoring software to create an ” image ” of the data to record and to record it to disc in the one session.

Packet writing is a scheme in which the recorder writes incrementally to disc in short bursts, or packets. Sequential packet writing fills the disc with packets from bottom up. To make it readable in CD-ROM and DVD-ROM drives, the disc can be closed at any time by writing a final table-of-contents to the start of the disc; thereafter, the disc cannot be packet-written any further. Packet writing, together with support from the operating system and a file system like UDF , can be used to mimic random write-access as in media like flash memory and magnetic disks.

The padding reduces the capacity of the disc, but allows the recorder to start and stop recording on an individual packet without affecting its neighbours. These resemble the block-writable access offered by magnetic media closely enough that many conventional file systems will work as-is. Although generous gaps the padding referred to above are left between blocks, the drive nevertheless can occasionally miss and either destroy some existing data or even render the disc unreadable.

The format itself was designed to deal with discontinuous recording because it was expected to be widely used in digital video recorders.

Many such DVRs use variable-rate video compression schemes which require them to record in short bursts; some allow simultaneous playback and recording by alternating quickly between recording to the tail of the disc whilst reading from elsewhere. The Blu-ray Disc system also encompasses this technology. This standard is contained in the Rainbow Books. The RID-Code consists of a supplier code e. Quoting Philips, the RID “enables a trace for each disc back to the exact machine on which it was made using coded information in the recording itself.

The use of the RID code is mandatory. Although the RID was introduced for music and video industry purposes, the RID is included on every disc written by every drive, including data and backup discs.

The value of the RID is questionable as it is currently impossible to locate any individual recorder due to there being no database. The Source Identification Code SID is an eight character supplier code that is placed on optical discs by the manufacturer. The SID identifies not only manufacturer, but also the individual factory and machine that produced the disc. According to Phillips, the administrator of the SID codes, the SID code provides an optical disc production facility with the means to identify all discs mastered or replicated in its plant, including the specific Laser Beam Recorder LBR signal processor or mould that produced a particular stamper or disc.

This combined knowledge may be very useful to law enforcement, to investigative agencies, and to private or corporate investigators. A significant motivation for introducing the SID code was to identify disc manufacturing plants producing unauthorised copies of commercial CDs. By the s, the production process for CDs had evolved from requiring a “clean-room” environment involving multiple processes, this demanding a substantial investment and likely to be confined to “responsible” organisations, into an activity that could be undertaken with “mono-liner” equipment, this having been developed in the late s and capable of packaging “the whole process into a single box” that could occupy “no more space than a couple of office desks”.

Consequently, the CD manufacturing industry had grown to include less reputable organisations and, by , could produce a volume of discs twice that of the estimated demand for “legitimate CDs”, with music industry organisations claiming that illicit copies were outselling legitimate copies by significant margins in some markets. Philips and the IFPI envisaged that combinations of codes, each identifying a disc mastering establishment and the manufacturing plant used to make a particular disc, would assist in identifying those responsible for illicit CD production.

However, the scheme relied on existing manufacturing plants upgrading their equipment to support the introduction of this measure, and the accompanying challenge of convincing such facilities was perceived as “a little difficult” in cases where those facilities were already involved in making considerable numbers of illicit discs.
