Method of transmission of a digital content stream and corresponding method of reception

A method of reception of a same one-to-many digital content stream streamed at a same time to at least two receivers, wherein the method comprises, implemented by each of said at least two receivers, further referred to as receiver:

• reception of a time reference;
• sending, from one of said at least two receivers, of a trick mode command message related to said same one-to-many digital content stream for streaming at a same time to said at least two receivers, said trick mode command message including at least one of stop, pause, fast reverse and fast forward and said received trick mode command message and comprising information allowing identification of a point in said same one-to-many digital content stream to which said sent trick mode command message applies;
• reception of a notification message notifying said receiver that a trick mode command message related to said same one-to-many digital content stream for streaming at same time to said at least two receivers is received from said one of said at least two receivers, said received notification message comprising information allowing identification of said point in said one-to-many digital content stream to which said trick mode command message applies for synchronous rendering of said same one-to-many content stream with others of said at least two receivers;
• reception of said same one-to-many digital content stream in accordance with said received notification message for synchronously rendering of said same one-to-many content stream with others of said at least two receivers, said same one-to-many digital content stream comprising information allowing identification of said points in said same one-to-many digital content stream for streaming at a same time to said at least two receivers, said points identifying one of a transport packet used to transport said same one-to-many digital content stream, an image, an audio frame, or a time stamp.

A device for streaming of a same one-to-many digital content stream at a same time to at least two receivers, wherein the device receives, from said at least two receivers, trick mode commands related to said streaming of a same one-to-many digital content stream to said at least two receivers, said device comprising:

• a storage register for storing a same one-to-many digital content stream;
• a time generator for generating a common time reference;
• a processor that transmits the common time reference to all of said at least two receivers, receives, from one of said at least two receivers, a trick mode command message related to said same one-to-many digital content stream for streaming at a same time to said at least two receivers, said received trick mode command message including at least one of stop, pause, fast reverse and fast forward and said received trick mode command message and comprising information allowing identification of a point in said same one-to-many digital content stream to which said received trick mode command message applies and sends, to all of said at least two receivers, notification messages notifying to said at least two receivers of said received trick mode command message related to said same one-to-many digital content stream for streaming at a same time to said at least two receivers, said notification messages comprising information allowing identification of a point in said same one-to-many digital content stream to which said received trick mode command message applies and controls synchronous rendering of said same one-to-many content stream by said at least two receivers;
• and
• a streamer that streams at least part of said same one-to-many digital content stream at a same time to all of said at least two receivers in accordance with the received trick mode command message providing synchronous rendering of said same one-to-many content stream by said at least two receivers;
• said same one-to-many digital content stream comprising information allowing identification of said points in said same one-to-many digital content stream.

A receiver that receives a same one-to-many digital content stream streamed by a server at a same time to at least two receivers, said receiver comprising:

• a network interface that receives a time reference from the server;
• a processor configured to send via the network interface a trick mode command message related to said same one-to-many digital content stream streamed at a same time to the at least two receivers, said trick mode command message including at least one of stop, pause, fast reverse and fast forward and said received trick mode command message and comprising information allowing identification of a point in said same one-to-many digital content stream to which said sent trick mode command message applies and receive a notification message from the server indicating a trick mode command message related to said same one-to-many digital content stream for streaming at same time to said at least two receivers was received from one of said at least two receivers, said received notification message comprising information allowing identification of said point in said one-to-many digital content stream to which said trick mode command message applies for synchronous rendering of said same one-to-many content stream with others of said at least two receivers;
• and
• a content decoder for decoding and rendering the received same one-to-many digital content stream in accordance with said received notification message for synchronously rendering of said same one-to-many content stream with others of said at least two receivers, said same one-to-many digital content stream comprising information allowing identification of said points in said same one-to-many digital content stream for streaming at a same time to said at least two receivers, said points identifying one of a transport packet used to transport said same one-to-many digital content stream, an image, an audio frame, or a time stamp.
