A hardware accelerated streaming arrangement, especially for RTP real time protocol streaming, employs a directing file determining the pointers, header lengths and offsets of a block of one or more data packets to be sent out through a network accelerated streaming system. The directing file is established by a control processor, for example working in the background, and is stored to provide information malting it possible to determine certain information including header sizes and pointers to RTP payload and other data, without the need during egress of the data for analysis related to the type of media or protocol concerned. This relieves the control processor of functions that would otherwise require attention, and permits the egress process to proceed in a repetitive manner, preferably relying insofar as possible on hardware elements for speed and reserving the control processors computational capacity for control functions that may be more complex but are infrequent and/or not time sensitive for streaming in real time. |
