摘要:
A video content delivery system is provided for set top boxes (STBs) that may be relocated as well as mobile clients using the Internet to retrieve content manifest files pertaining to the geographic area in which they are located. To provide this system, the edge cache in each geo-location region of a content provider is configured to append location specific metadata to a client's original HTTP request for content, making the request geo-location or region specific. The specific metadata appended by the edge cache in each region prevent clients from bypassing blackout or other content restrictions by moving from a non-restricted area and sending inaccurate location information. In another feature of the system to prevent client bypassing of blackout restrictions, the edge cache when communicating with the STB removes any location specific information which the client provides.
