The FCC rules would have required circuitry be included as a mandate in all new digital receivers to enforce copy protection. Many devices were already starting to include it. EFF Presentation on the Broadcast Flag The Onerous "Broadcast Flag" PC Mag by John C. Dvorak U.S. appeals court tosses TV anti-piracy measure Washington Post Prediction: Congress Will Pass HDTV Copying Law From TVpredictions.com UpdateThe MPAA is working on new legislation to broaden the FCC's power.This article: "The draft bill says, simply, that the FCC will 'have authority to adopt regulations governing digital television apparatus necessary to control the indiscriminate redistribution of digital television broadcast content over digital networks.' The DC Circuit nixed the flag on the grounds that the FCC didn't have the authority. This language would clear that up"

Unlike standard television broadcasting, there are a limited number of viewers that an Internet television station can accommodate. These limitations are determined by the amount of bandwidth the network media server has available. A popular Internet television station would require large amounts of bandwidth to provide the broadcast to a large viewing audience. There are readily available software-based broadcasting alternatives that do not require large amounts of bandwidth for Internet television distribution. Peer to Peer (commonly referred to as P2P) broadcasting allows viewers using specialized software to re-distribute the media broadcasts. This eliminates the need to utilize costly centralized media servers to distribute the broadcast. Any size business or group can establish an effective media broadcast presence without the huge costs normally associated with Internet broadcasting. Only a small amount of bandwidth is required for a global Internet broadcast distribution using this method. P2P Internet broadcasting provides bandwidth friendly results for low bit rate content (content that is encoded at low speed) and can support a virtually unlimited number of users. This method also provides effective security against Denial Of Service (DOS) attacks which can cripple a centralized server network architecture. The streaming rate of a P2P broadcast is limited by the overall network bandwidth capacity. Most Internet Service Providers have generally placed a cap on the maximum upload capacity of high speed Internet subscribers. Networks such as this are a frame work of various upload and download bandwidth capabilities. Exceeding the networks overall average bandwidth causes the video broadcast to degrade in quality of service. A typical P2P stream should not exceed 128 kbs. Network congestion or individual relays ( P2P clients ) departing the network can also cause instability of a broadcast stream. Low bandwidth broadcasts such as audio broadcasts generally do not suffer as much from this anomaly as do higher bandwidth video streams. This problem can be partially alleviated by increasing the stream buffer size within the media player. There are both commercial and non commercial options that offer P2P broadcast ability for Internet television. This article will cover free open source software. Open source is an initiative that allows people to have access to the source code of software. This is the actual nuts and bolts that allow the software to operate. This initiative also allows people the ability to redistribute and or modify the source code thus allowing improvements and adaptations of the software. (http://www.opensource.org)
PeercastPeercast is a P2P media broadcast application that is available for the Windows, Unix and Mac operating systems. It is compatible with Shoutcast, Icecast and Windows Media streaming protocols.The software was originally designed to use Gnutella as a basis for broadcast distribution. The software now uses a hierarchical topology for media broadcast distribution. Hierarchical topology (also called Tree Networking) directs data to flow from a point of origin to individual clients. These individual clients allow additional clients to request access to that data flow through them (the individual client). Each additional client within the network will then act as a data relay to others. This new method provides greater scalability and more data organization. Broadcast station data is collected by the YP directory. This data is continuously updated by individual broadcasters. Listeners / viewers (client software) provide the connection points between themselves, the broadcasters and others. Each broadcaster has the option of including a digital signature to enable media broadcast authentication. This will prevent their broadcasts from being hijacked and replaced with alternative material. The following video codecs are supported by Peercast: VP3, VP6, Theora and WMV. Codecs are software programs that allow media to be digitally encoded or decoded using a specific compression architecture. Peercast can also be used for audio broadcasting and can be configured to use several audio codecs. The software can be used to broadcast individual media files or entire playlists of media files as well. Hardware network routers use Network Address Translation to provide internal IP addresses for computers within a Local Area Network. Traffic flowing through NAT must be converted from internal IP addresses to external IP addresses. P2P traffic routing through NAT usually requires software port forwarding to function properly. Peercast is NAT friendly software and requires no special port forwarding. A plug-in is available for the popular Winamp media player. (Winamp versions 2.x and 5.x) This can be installed and used by clients to easily receive a Peercast station. The Peercast network provides a real time online station directory of current broadcasters. (http://yp.peercast.org) The main Peercast client must be installed to broadcast using this P2P network. Additional resourcesPeercast Plug-In InformationHow to broadcast video with Peercast Peercast Frequently Asked Questions Peercast Help Peercast Community Forum FreeCastFreeCast is a Java P2P broadcast application. Users must install the Java Runtime Environment, which is available for the Windows, Unix and Mac operating systems.This software can source media for broadcasting using several Open Source software applications. These include JRoar, Icecast, Flumotion, EzStream and the Video Lan Client. The software has a internal audio and video player that supports both the Ogg Vorbis open source audio codec, and the Theora open source video codec. The inclusion of the internal media player allows the software to function without the need of downloading or installing any additional media codecs. FreeCast can be configured to use the Java Web Start feature for automatically loading and launching the application. This enables a "one click" approach for web based end users. Each broadcaster has the option of including a digital signature to enable media broadcast authentication. This will prevent their broadcasts from being hijacked and replaced with alternative material. This software uses a hierarchal method of media broadcast distribution. Each broadcaster acts as a central node with listeners / viewers receiving data from them and relaying to other listeners / viewers. FreeCast is continuing software development that will allow its deployment across networks that interact with network routers that utilize Network Address Translation (NAT). Port forwarding is currently required to accommodate NAT routers. The Web Start FreeCast GUI player can be customized with the broadcaster logo and colors. This can allow the software to be integrated with the individual broadcaster’s web site. FreeCast maintains a directory of stations located here (http://www.freecast.org/listen) Additional resources:FreeCastTheora Ogg Vorbis IceCast JRoar Flumotion Video Lan Client Ezstream
Up to this point, at the insistence of the police Unions, these systems could be turned on and off by the office in the vehicle and thought of as "video evidence systems" aimed at strengthening cases against suspects. With this in mine, officers are able to turn off and some can even rewind and record over video they didn't want to be seen.
Since September 11, 2001, and the introduction of the USA PATRIOT ACT, these video systems are taking on a new significance.
Due to a rash of Police Brutality cases, things are starting to change. Local governments are starting to see video as a way to reduce liabity by providing verifable proof that the police were acting properly. "Resisting any change in police methods, are the police advocacy organizations . the unions and their legal representatives . along with police chiefs. The San Jose union strongly rejected public meddling in police killings, so none of the five cases of fatal shootings by San Jose police in 2004 went to an open grand jury."
Palo Alto, Ca - ArticlesPolice on trial Two Palo Alto CA police are charged with brutally beating a man without cause. Their trial has become a forum on police practices in generalACLU, Palo Alto, CA Resolution Committee to discuss police-camera policy Race relations between police, community tense Bizarre storyA friends Hummer was stolen from in front of his apartment here in Los Angeles. It was reported stolen at 7 am or so. At 9am a ticket patrol gave the stolen vehicle a parking ticket and as the ticket was being issued the suspect ran in and drove the vehicle away. All of this was recorded on the police car video recording system, and used a evidence for the ticket, since the officer couldn.t catch the plate number, but the video did! One hour later the traffic officer returned and once again caught the thief on video and issued and second ticket on the stolen car.It was from the tickets being mailed out and quote on the bottom of the ticket stating, "Operator drove off, plate number from video" that we knew they had a video of the incident. Of course the LAPD still expect him to pay the parking fines, and have yet to acknowledge the fact that they have video of the thief in there possession.

Streaming Media Also from ITI, these guys put on the Streamingmedia shows.
This project (which is part of this year's SIGGRAPH) has absolutely blown my mind. Basically they photograph an object with the photo sensor at one point, and the light projector at another, and use the Helmholtz reciprocity algorithm to virtually switch the locations of the camera and projector, showing exactly what the light source "sees"! If that doesn't make sense to you, check out the research page and make sure to watch the 60MB video at the bottom. The playing card trick will leave you speechless!

OLED (Organic Light Emitting Diodes), LEP (Light Emitting Plastic), PLED (Polymer Light Emitting Diodes), EL (ElectroLuminescence). The technology come in several variation and just as many names, but basically it's a simple platic like materials that light up when electricity is applied. For a long time people have been wanting to make displays using these technologies but the ability to manufacture a high res display just didn't exist. OLED's hold the promise to allow flexible, Low Power, high resolution, lightweight, inexpensive displays to be mass produced using a simple ink jet printing process. Whole Cinema screens could be producted, that can do better on all measures than projector based systems could ever hope for.

Before Lanuch was aquired it was planning " new service that Launch will offer to universities nationwide this fall. Bucknell and Georgia Tech are the first universities to sign up for Launch College Direct, which broadcasts music and videos onto campus networks via servers connected to Launch by satellite. The high-volume streaming is achieved through technology developed by iBeam Broadcasting Corporation of Sunnyvale, Calif. Launch is billing it as the ultimate solution to Napster-related network problems at universities. "

A Slashdot poster (it's in this week's links) purporting to be an Apple employee dropped a couple tidbits that fill-in the blanks for understanding Apple's still unannounced movie download service. The man or woman said that Apple would be fudging somewhat its definition of High Definition video to save bandwidth and required processing power, starting instead of 720p-24 with half-HD and anamorphic 720-by 486 (look in the links for what anamorphic means). Apple may well offer those sub-HD versions of HD, but from the music videos they are already starting to offer in HD I think they'll offer 720p and 1080i, too. Remember, the real market is download-and-play, not streaming. (I Don't agree with that last statement, there just isn't enough bandwidth and protocols to make that happen yet.- JLS) The more interesting item in this Slashdot post, however, was the idea of Apple doing a video equivalent of its AirPort Express WiFi repeater that has audio output to link iTunes to your stereo system. This AirPort extension is the last piece needed for Apple's video service and answers a lot of questions. Why doesn't the Mac Mini have an optical audio port? Because the AirPort has one, instead. Why isn't the Mac Mini more powerful? Because it doesn't have to be. The Mini becomes a storage and downloading device and H.264 decoding is handled in the AirPort gizmo using one of the H.264 hardware decoder chips coming on the market for around $20. So Apple takes over video and movies while Yahoo threatens with a low-priced music subscription service and Google threatens to take control of, well, everything.
