摘要	Techniques that provide cost effective optical fiber communication links for HDCP transmission systems and the like are provided. A single fiber for bidirectional communication is enabled, without wavelength selective unit to achieve the HDCP transmission. One embodiment of the present invention has a forward channel using a light source (e.g., VCSEL at about 850 nm) in the GHz modulation level (e.g., 1 GHz or greater), and a corresponding photodetector. The backward channel has a light source (e.g., LED at 630 nm) in the MHz modulation level (e.g., 10 MHz or less), and a corresponding photodetector. One application is for realizing a home entertainment system (e.g., DVD player and high definition television) that employs an HDCP-enabled communication link to transmit copy restricted digital content.
其他摘要	提供了为HDCP传输系统等提供成本有效的光纤通信链路的技术。启用单根光纤进行双向通信，无需波长选择单元即可实现HDCP传输。本发明的一个实施例具有使用GHz调制级（例如，1GHz或更高）的光源（例如，约850nm的VCSEL）的前向信道，以及相应的光电检测器。后向信道具有MHz调制级（例如，10MHz或更低）的光源（例如，630nm处的LED），以及相应的光电检测器。一种应用是用于实现家庭娱乐系统（例如，DVD播放器和高清晰度电视），其采用支持HDCP的通信链路来发送复制受限的数字内容。
主权项	A bidirectional HDCP transmission system using a single optical fiber having a core and cladding, the system comprising: a forward channel for delivering protected digital video and audio content, wherein the forward channel is substantially communicated in the core of the single optical fiber; and a backward channel for establishing an HDCP-enabled transmission, wherein the backward channel is at a lower data rate relative to the forward channel and is substantially communicated in the cladding of the single optical fiber.
