Abstract
In a receiver coupled to a recording device that includes a digital storage medium, there is provided a method for providing trick mode operations for sub-channels of multiplexed streams stored on the digital storage medium. A trick mode command specifically directed to a particular sub-channel of a multiplexed stream is sent to the recording device. Frame data corresponding to the particular sub-channel is received from the recording device. Trick mode data for the particular sub-channel is extracted from the frame data.

A method for providing trick mode operations for sub-channels of multiplexed streams stored by a digital storage medium, comprising the steps of:
- receiving at the recording device, a trick mode command directed to a particular sub-channel of a multiplexed stream;
- identifying frame data stored by the digital storage medium corresponding to the particular sub-channel;
- and
- extracting, from the frame data, trick mode data for the particular sub-channel.
In combination with a digital storage medium coupled to a receiver, a method for providing trick mode operations for sub-channels of multiplexed streams stored on the digital storage medium, comprising the steps of:
- receiving, from the receiver, a trick mode command specifically directed to a particular sub-channel of a multiplexed stream;
- and
- sending, to the receiver, in response to receiving the trick mode command, frame data corresponding to the particular sub-channel stored by the digital storage medium for extraction of trick mode data there from, the trick mode data corresponding to the particular sub-channel.
