A demonstration of a home-made AM broadcast receiver. The set uses two transistors (MPF102 FET & BC548 NPN) and one audio IC (TDA 2822). The test was done in the middle of the day with no external antenna. If done at night many interstate stations would have been heard. The circuit of an earlier version (without the IC audio amp) appears here: www.alphalink.com.au

Expression Encoder - Broadcast Video over LAN.wmv

Expression Encoder - Broadcast Video over LAN.wmv Video Clips. Duration : 8.25 Mins.
Video Streaming over LAN is an interesting concept and has a lot of practical implications. I used it to stream a movies to various rooms at home and at office (NCSU - University of Peradeniya) am needing to use if to broadcast a student registration. Alternatives: VLC Player [ encountered issues with newer versions of VLC ] Where to get: www.microsoft.com HowTo [Basic]: @Senders End [ IP Address is : ABCD - use ipconfig to obtain ] 1. Open Expression - Select Live Broadcasting Project 2. Select Live Source or Add File Source 3. Cue the source by clicking the 'Cue' button 4. Go to Output - Select Streaming and then Broadcast 5. Go to Encoding - Do necessary changes to Audio / Video 6. Press 'Start' button @Receivers End 1. Open Windows Media Player [ or what ever player ] 2. Open URL and enter mms://[IP Address of Broadcaster]:[port no] ex: mms://ABCD:8080 / mms://192.168.0.21:8080 Considerations: Video Encoding is a process intensive task. The more Bit Rate it has and the higher the width and height of the video output would be, more the processor would be used. A processor over Core i3 is recommended for the server. And you are done!
