Patent Images
1. A method of increasing transmission bandwidth when delivering content, comprising:
- storing predefined content segments in a memory device associated with a receiver prior to receiving a signal for controlling playback of said predefined content segments;
receiving a signal transmitted via a content transmission system and generating via the receiver an output signal to a user to playback content in accordance with the received signal, said received signal comprising segments of program content and segments of control data;
using the control data in the received signal to access selected said predefined content segments from said memory device; and
playing back the selected said predefined content segments in said output signal in accordance with said control data;
wherein said memory device comprises index data with which to identify each of said predefined content segments stored therein, and said control data in the received signal comprises selected said index data corresponding to the selected said predefined content segments to access said predefined content segments corresponding thereto from said memory device.
