Technical Examples

Set top boxes are provided with access to full EIT data streams without having to off-tune from one transport to another. If off-tuning is required, however, a locking mechanism substantially reduces or eliminates service interruption. Data in the additional EIT data streams in the non-home transports is reorganized to be sent by time rather than by service. EIT data is stored in the set top box in an architecture which significantly reduces the redundancy inherent in EIT data, allowing a full 7 days of EIT data to be stored in the set top box memory. The set top box of the present invention is backward compatible with conventional set top boxes.
