Abstract
In a digital video network, an encoded multimedia data stream is transmitted over the network to the end user terminal where it is decoded for viewing by a subscriber. The network includes a decoding delay reducer, which processes the encoded multimedia data stream to optimize the multimedia data stream to the operating condition of the digital video network. The optimization of the multimedia data stream enables the end user terminal to decode the encoded multimedia data stream sooner after receipt, which reduces channel change time experienced at the end user terminal due to decoding delay.
Claims20
A device for decreasing channel change time, the device comprising:
- a network parameter input for inputting network parameters of a communications network;
- and
- a data post-processor for processing a multimedia data stream to be broadcast over the communications network;
- wherein the data post-processor processes the multimedia data stream based on the network parameters to reduce decoding delay time of the multimedia data stream.
A live broadcast multimedia encoder comprising:
- a network parameter input for inputting network parameters of a communications network;
- and
- a data encoding system for encoding a multimedia data stream to be broadcast over the communications network;
- wherein the data encoding system encodes and processes the multimedia data stream based on the network parameters to reduce decoding delay time of the multimedia data stream at an end user terminal.
A method for decreasing channel change time, said method comprising:
- receiving network parameters of a communications network;
- and
- post-processing a multimedia data stream based on the network parameters to reduce decoding delay time.
