发明名称 SYSTEMS AND METHODS FOR IMPROVING HIGH- BANDWIDTH DIGITAL CONTENT PROTECTION (HDCP) AUTHENTICATION WITH DIGITAL VIDEO INTERFACE (DVI) OR HIGH-DEFINITION MULTIMEDIA INTERFACE (HDMI) RECEIVER DEVICES
摘要 Systems and methods for improving HDCP (High-Bandwidth Digital Content Protection) authentication with DVI or HDMI receiver devices are provided. An HDCP transmitting apparatus according to the invention may include a computer and a look-up table accessible by the computer. The look-up table may include a database for storing an interoperability characteristic for an HDCP receiving device. The computer can communicate with the HDCP receiving device. The computer may also insert a delay in an initiation of the authentication and/or communication of content between the HDCP transmitting apparatus and the HDCP receiving device. The magnitude of the delay may be based on an interoperability characteristic retrieved from the look-up table that corresponds to the HDCP receiving device. The inserting may occur prior to the implementation of authentication initiation and ongoing link integrity checking between the transmitting apparatus and the HDCP receiving device.
