Abstract :
This paper presents the first wireless LAN baseband LSI capable of transmitting high-definition audio with video (HD-A/V) content requiring secure content protection. The LSI fully complies with IEEE 802.11a, e, h, and i. The hybrid coordination function controlled channel access (HCCA) of 802.11e is employed to reserve the transmission period for HD-A/V content. In addition, the block acknowledgement of 802.11e with a forward error correction mechanism is introduced to increase the throughput. Moreover, the digital transmission content protection over the Internet protocol (DTCP-IP) is implemented to prohibit casual copying. High availability of this LSI is provided by two kinds of host interfaces (PCI-bus and HC-bus), an MPEG-2 transport stream interface, and a digital beam forming LSI interface
