Abstract

Abstract A digital data transmission interface and method are disclosed for providing a stream of digital data packets to a digital recording device. The interface receives a plurality of digital data packets, develops an encapsulated received data packet, which includes a received digital data packet together with a corresponding timestamp, and couples the encapsulated received data packet to a digital recording device. Generated data packets may also be encapsulated and coupled to the recording device together with the encapsulated received data packets.

Claims Analysis

Total Claims: 32
Claim 1
Independent Claim 105 words
A method of providing a stream of data packets to a recording device, comprising the steps of: receiving a locally generated stream of data packets and a transmitted stream of data packets, the transmitted stream of data packets having an original temporal spacing between data packets; and multiplexing the locally generated data packets and the transmitted data packets to form a multiplexed stream of data packets so that the multiplexed stream of data packets preserves the original temporal spacing of the transmitted data packets and so that the locally generated data packets are distributed into a plurality of temporal spaces between the transmitted data packets.
Claim 2
Independent Claim 105 words
A method of providing a stream of data packets to a recording device, comprising the steps of: receiving a locally generated stream of data packets and a transmitted stream of data packets, the transmitted stream of data packets having an original temporal spacing between data packets; and multiplexing the locally generated data packets and the transmitted data packets to form a multiplexed stream of data packets so that the multiplexed stream of data packets preserves the original temporal spacing of the transmitted data packets and so that the locally generated data packets are distributed into a plurality of temporal spaces between the transmitted data packets.
Claim 3
Dependent Claim 16 words
