Packet processing at a server
A server processers received real-time transport protocol packets from a first device to obtain sequentially ordered packets at a first buffer. The server decodes the sequentially ordered packets to obtain decoded packets at a decoder. The server encodes the decoded packets to obtain encoded packets at an encoder. The server transmits the encoded packets from the encoder to a storage unit. The server fetches the encoded packets from the storage unit at a first interval using a second buffer. The server transmits the encoded packets from the second buffer to a second device at a second interval.
