Toshiba HD-A35  (Source: AV Watch)
The third time's a charm with Toshiba's HD DVD player lineup

Toshiba isn't standing still when it comes to the development of HD DVD players. The company announced today that it has revamped its entry-level, mid-range and high-end players and that all three will retail for under $500.

"With a majority market share in unit sales of next generation DVD players, consumers are speaking loud and clear, and they are adopting HD DVD as their HD movie format of choice," said Jodi Sally, VP of Marketing for Toshiba's Digital A/V Group. "Because of the proven manufacturing efficiencies of the HD DVD format, Toshiba can bring this level of innovation in technology to a new generation of players with cutting-edge functionality at affordable prices."

The first new model is the entry-level HD-A3. Toshiba didn't divulge many details on the HD-A3 other than the fact that it features 1080i output. The mid-range HD-A30 adds support for 1080p output along with what Toshiba calls "CE-Link" or HDMI-CEC. CE-Link allows for a two-way connection between the HD DVD player and TV over HMDI.

The high-end HD-A35 also features 1080p support and CE-Link, but also adds support for Deep Color over HDMI, 5.1 channel analog audio output and High Bit Rate 7.1 Audio over HDMI.

All three players feature a slimmer exterior design with rounded edges and a high-gloss black finish. According to Toshiba, the third generation players are half as tall as the first generation units.

Toshiba's HD-A30 will be available in September at a price of $399.99. The HD-A3 and HD-A35 will be available in October with price tags of $299.99 and $499.99 respectively.

No. You're confusing a few different concepts here. To understand why deinterlacing can be done perfectly for recorded content, you have to first understand why its NOT possible for broadcast video. The key is in understanding the concept of time indices.

In broadcast video, you have a camera (or other source) continously capturing half-frames, then transmitting them. The time indices between the two halves of a full frame, however, don't match, which means the simplest manner of deinterlacing (known as "weaving", or simply adding together consecutive fields) results in severe artifacting. "Bobbing" is another technique used, which consists of simply line-doubling a half-frame into a full. This doesn't cause artifacting-- but you lose half your resolution. More sophisticated algorithms exist such as inverse telecine and advanced motion compensation algorithms. These can give you very close to the original source, but still its not perfect.

Now, lets consider prerecorded 1080p@24 material-- what you find on a HD-DVD or BD disc. The full frames already exist; that's how they're encoded and stored. To transmit this to a 60hz 1080i set, your player simply reads a full frame, then does 3:2 pulldown, transmitting frames like this, "112223344455666", etc. But the time indices MATCH between each half-frame (they were originally created from one full frame, remember). So when you add consecutive fields together, (the "weave" operation) you get back your original source content-- the full frames you started with. There is no need for inverse telecine or any other algorithm. Thia is, in fact, the reason why the PLAYER can deinterlace without signal loss...because of the matching time indices on frames.

Now, the only problem here is a really dumb, cheap set just might decide to "bob" your 1080i signal instead of weaving it. But, as I said earlier, a display that stupid is probably going to munge your 1080p signal anyway. Some of them do indeed bob both 1080i and 1080p, effectively converting them both a line-doubled 540p signal.

Hopefully the above clears up a few misconceptions. The important thing to remember is that the 1080i transmitted by cable companies and broadcast stations has, from an interlacing perspective, nothing in common with a 1080i signal from a disc player.
