Receiver for reducing power consumption and digital broadcast receiving system including the same

摘要

A receiver includes a frame boundary detector and a link controller. The frame boundary detector receives a plurality of transport stream (TS) packets and generates a control signal based on boundary information of the TS packets. The link controller disables a part of the receiver to disable forwarding of subsequent TS packets in response to the control signal. Each of the TS packets is a multi protocol encapsulation (MPE) section or a multi protocol encapsulation-forward error correction (MPE-FEC) section.

1. A receiver comprising:
a frame boundary detector configured to receive a plurality of transport stream (TS) packets, determine a maximum count of errors from the TS packets and generate a control signal based on boundary information in the TS packets when a number of multi protocol encapsulation-forward error correction (MPE-FEC) sections have been received that is less than the count; and a link controller configured to deactivate a part of the receiver to disable forwarding of subsequent TS packets in response to the control signal, wherein each of the TS packets is a multi protocol encapsulation (MPE) section or a multi protocol encapsulation-forward error correction (MPE-FEC) section, wherein the frame boundary detector comprises an error detector configured to determine whether the TS packets including the MPE section and the TS packets including the MPE-FEC have errors based on header information of the corresponding TS packets to generate first error information indicating errors within the MPE sections and second error information indicating errors within the MPE-FEC sections, and wherein the frame boundary detector generates the control signal in response to an error generation code, the code generated when the boundary information includes a table boundary value or when at least one MPE-FEC section is received and the boundary information excludes the value.
