Abstract
The invention relates to a method for transmitting a television data stream via a wireless network connection. The method comprises receiving at least one television data stream via the User Datagram Protocol (UDP); converting the at least one UDP television data stream into a Transmission Control Protocol (TCP) data stream; and transmitting the TCP data stream via the wireless network connection over a point-to-point link.
Claims15
A method for transmitting and receiving a television data stream via a wireless network connection, comprising:
- receiving at least one television data stream via the user datagram protocol;
- converting said at least one user datagram protocol television data stream into a transmission control protocol data stream;
- transmitting said transmission control protocol data stream via said wireless network connection over a point-to-point link;
- receiving said transmission control protocol data stream carrying said at least one user datagram protocol television data stream via said wireless network connection;
- extracting said at least one user datagram protocol television data stream from said transmission control protocol data stream by restoring the original user datagram protocol television data stream;
- and
- outputting said at least one user datagram protocol television data stream as a conventional user datagram protocol television data stream for being used in conjunction with conventional user datagram protocol based IPTV playback devices.
A system for transmitting and receiving a television data stream via a wireless network connection, comprising:
- an interface configured to receive at least one television data stream via the user datagram protocol;
- a converter configured to convert said at least one user datagram protocol television data stream into a transmission control protocol data stream;
- a wireless transceiver configured to transmit said transmission control protocol television data stream via said wireless network connection over a point-to-point link;
- a wireless transceiver configured for receiving said transmission control protocol data stream carrying said at least one user datagram protocol television data stream;
- an extractor configured for extracting said at least one user datagram protocol television data stream from said transmission control protocol data stream by restoring the original user datagram protocol television data stream;
- and
- an output interface for outputting said at least one user datagram protocol television data stream as a conventional user datagram protocol television data stream for being used in conjunction with conventional user datagram protocol based IPTV playback devices.
