## Internet TV/Radio Multicast

An IP Multicast model has been implemented socket programming in c.   

## Model Flow: 

- Initially by running the `server` program, the server setups 2 multicast groups at different multicast address.

- Both groups have threads running for transmission of data which are active after the setup immediately. 

- When a new client arrives, it receives the available stations present through a **TCP Socket**.

- ON selecting a group, the client immediately starts receiving the data and other stream information through **UDP Sockets** on 2 different threads. 

- The Client can view the video/audio in real time, based on its joining time to the group. 

- Client also has a functionality to pause and play the stream, by keyboard interruption. 

- Multicast group address and ports are fixed in both server and client programmes. 

## Compiling and Running Instructions

- Server   

  - Compiling: `gcc server.c -o server -lpthread`  

  - Running: `./server PORT`

  - `PORT`: Server Port

  - For sending audio/video files from multicast group, the files must be converted into streamable format.   

  It can be done using following command:   

  `ffmpeg -i  -f mpegts `

  

- Client

  - Compiling: `gcc client.c -o client -lpthread`

  - Running: `sudo ./client SERVER_IP PORT` (`sudo` is mandatory, as it accesses accesses network interface).

  - `SERVER_IP`: Server IP (`0.0.0.0 / 127.0.0.1` if running in same machine else IP address of Server)   

  - `PORT`: Client Port

  - For Playing the audio/video file received through socket in client, run the following command in new window: `ffplay -i `

  - For pause operation, press `p` on the terminal receiving the data. It acts as a keyboard interrupt.

  - For restart, press `r` on the terminal.

  - Also, do change the interface name in code according to machine (Use `ifconfig` command).
