DVD Player as 802.11b Peripheral

sysadmn writes "Instead of building a PVR from a computer, why not let your DVD player access the computer you already have? That's the thinking behind Sonicblue's new Go-Video D2730. The just-announced DVD player will use an 802.11b (Wi-Fi) wireless network connection to access content on PCs, such as photos, music and videos. The player is aggressively priced at about $250 US and is due out in first quarter 2003. Full details are on CNET."

    I notice on home home 802.11b network that the 11mbps connection between my den PC and upstairs office PC is nowhere near fast enough to stream high quality compressed digital video (e.g. DivX). How is this player going to be able to pull it off?

      802.11b is plenty fast to stream DivX. Now as some point you could have too many players (and other 802.11b devices) in a home (possibly a bigger problem in apartment buildings?) trying to share the same bandwidth.

      A DVD quality SVCD runs at arounf 3000 kbps (around 3 Mbps), and a simmilar quality DivX around 1500 kbps (1.5 Mbps). So I don't know what you are doing at your place, but a 11 Mbps conneciton should handle them just fine. In face, my 10 Mbps nic can play a SVCD over the LAN perfectly.

      11MBPS is probably fast enough; however, it's worth pointing out that 11MBPS isn't guaranteed by 802.11B. In fact, the connection speed can fall back to fairly slow speeds in the presence of a less than perfect RF link. I can't recall the bottom end off hand (1MBPS?).

      It may be that you are seeing partial signal blockage or reflectance problems between your office and den. Try using something to benchmark the actual connection speed (if you haven't done so already).

      11Mbps is the through the air "wire" speed that is the maximum speed that all data is being sent. The amount of usefull data on even the best .11b equipment is about 6.3Mbps or ~700KB/s which should be more then enough for DivX and even most MPEG2 streams but some could theoretically be 9.8Mbps but average 4.7 Mbps typical rate for movie on single layer with 3 multichannel audio tracks.

      11Mbps is a "marketing number". The protocol has a lot of overhead- data that is transmitted for servicing the connection. When it comes to speed 802.11B is moving your data (payload), it is about 3-4 MBps, shared between two directions.

      Not illegal, more against the liscense from the DVD Forum that companies have to sign to get a valid CSS decryption key. There are technologies that the DVD Forum does not think can be properly secured so they do not want content going across them. Besides this is for reading data off a pc through the DVD player to the TV, not for transfering the DVD data to the PC. This thing is basically a DVD player with a network jack that allows the same kind of multimedia features as some of the current players that can play SVCD's, mp3 cd's and have CF and MMC readers so they can display jpegs from your digital camera. Basically an all in one media center that uses the tv for a display. Since my pc is already in the living room and hooked up to the S-Video port on the tv this does nothing for me personally but some people don't have the pc in the living room and want to keep it that way so this would allow them to access all that stuff off the pc upstairs (with a 802.11b wireless bridge attached to the network port I would assume).

    I've found that trying to stream anything worthwild over a .11b link is just too iffy. I often stream video files from my server to whereever I am sitting with the laptop. With the netgear card reporting a full speed connect at ~60% signal strength and 100% quality it is kind-of jerky at times. I know I'm pushing the limits of what that little wireless connect can do.

    Now I can deal with it for now because I'm not expecting it to perform perfectly. However, what is going to happen when Joe Consumer picks one of these up, hooks in the wireless part and tries to stream his DVD rip collection and it gets .3FPS?

    Well firstly your solution presumes that one's time is free: If you put a value on the hours you spend putting the system together, configuring all of the software, etc, suddenly it isn't economical. Rather than seeing it as a hobbyist, think "If I were to go into business making these for other people, what would I charge?". I suspect that you'd be surprized. Of course on top of all of that is the expense and availability issues in finding a "stereo component" sized computer case that integrates into an AV system (no dropping a giant beige case sputtering away with a dozen fans isn't viable).

    Secondarily, it's highly likely that they're using one of the new Sigma Designs chipsets, the new one which includes some Divx support. Indeed if I were to build a PC based playback device (the only thing holding me back is the case, as previously mentioned. For fans I'd reduce that by using a Via C3 with passive cooling), I'd base it around a Sigma Designs XCard.

  17. ReplayTV by crow · · Score: 3, Interesting

    I love my ReplayTV. There are two priority levels: Non-guaranteed and Guaranteed. If you guarantee a recording, it will reserve hard drive space for the show and it will record it. It won't let you set two guaranteed shows for the same timeslot. The only time you run into problems is when the network shifts the schedule slightly so that two shows overlap when they normally wouldn't.

    As to finding new shows, you can do a search fairly easily, and you can browse the guide. It's trivial to tell it to record something, and also trivial to change the settings on something already scheduled.

    What Replay lacks is a to-do list. So if you have a bunch of non-guaranteed things (like my wife's "Shakespeare" theme or my "Stargate" theme), it will pick the one to record using a fairly cryptic algorithm (which one starts first; which one is on a lower channel; which theme was create first).

    Actually every "media" device in your house should have this capability. There should be such a thing as "storage" (i.e. hard drive) and everything from your video game console to your stereo to your video playback device and your computer should access it.

    Put the "consoles" in their proper perspective; computers will be great for surfing the net and ordering content. Your video playback console is great for playing back your videos, and your stereo console is great for playing back music.

    The point I'm making here is everything should be contected together, but accessed in with the console that makes sense. IMO, playing tunes and watching downloaded videos on a computer stinks. Playing video games on the TV rocks, but video game consoles with their own storage devices sucks.

    If 802.11b wireless is the link that ties all these together, great, but it should be seamless and painless to the user to set it up.

    Oh yeah, it needs to be secure too. ;)

    Exactly.

    However, I stream video from my desktop (with TV tuner card) to a laptop (with TV-out) under the TV over 802.11b. I do this by mounting an NFS volume over a VPN I establish from the laptop to the desktop. My datarate is set so 1 hr of video will just fit on a 700 MB CD (in case I see a show I want to keep). I'm also running an ad-hoc (rather than access point) network, if that makes any difference. The laptop and desktop are fairly close together, but there are a few walls.

    Under these conditions, I can just eek out enough bandwidth. There's more room for error if I stream over HTTP, but then I can't seek within the stream, so I stick with NFS.

    Very occasionally for no apparent reason I'm unable to use the player - interference from something, I assume.
