Digital receiver system
A system for receiving wireless digital video transmissions over a WLAN comprising a base station (BS) adapted to provide a conditional access back-channel connection to one or more service providers; and a mobile digital video receiver (DVR) adapted to transmit a request for conditional access to the BS.
1 . A mobile digital video receiver (DVR) for receiving digital video transmissions comprising:
a controller adapted to transmit over a wireless local area network (WLAN) a request for conditional access to a selected digital video network channel.
2 . The DVR of claim 1 wherein said DVR is further adapted to receive digital video transmissions over a WLAN.
3 . The DVR of claim 2 , wherein the WLAN is a WiFi (Wireless LAN—WiFi), WPAN (Wireless Personal Area Network), WiMAX (Broadband Wireless Access), MBWA (Mobile Broadband Wireless Access), and/or WRAN (Wireless Regional Access Network), or any combination thereof.
4 . The DVR of claim 1 further adapted to receive digital video transmissions directly from a digital video network.
5 . The DVR of claim 4 wherein said digital video transmissions are digital television (DTV) broadcasts.
6 . The DVR of claim 4 wherein said digital video transmissions are digital multimedia broadcasts (DMB).
7 . The DVR of claim 1 wherein said DVR comprises a portable computer (laptop computer).
8 . The DVR of claim 1 wherein said DVR comprises a PDA (personal digital assistant).
9 . The DVR of claim 1 wherein said DVR comprises a cellular phone.
10 . The DVR of claim 1 wherein said DVR comprises a portable media player.
11 . The DVR of claim 1 wherein said DVR comprises portable navigation equipment.
12 . The DVR of claim 1 wherein said DVR comprises a portable television.
13 . The DVR of claim 1 wherein the DVR is further adapted to selectively receive digital video broadcasts through the WLAN or directly from a digital video network.
14 . The DVR of claim 13 wherein the DVR is further adapted to compare signal quality of the digital video network and the WLAN.
15 . A base station (BS) for retransmitting wireless digital video transmissions over a WLAN comprising:
a base station unit (BSU) comprising a conditional access module (CAM) adapted to provide a back-channel connection to one or more service providers.
16 . The BS of claim 15 wherein the WLAN is a WiFi (Wireless LAN—WiFi), WPAN (Wireless Personal Area Network), WiMAX (Broadband Wireless Access), MBWA (Mobile Broadband Wireless Access), and/or WRAN (Wireless Regional Access Network), or any combination thereof.
17 . The BS of claim 15 further adapted to receive wireless digital video transmissions directly from a digital video network.
18 . The BS of claim 15 wherein said digital video transmissions are wireless digital television (DTV) broadcasts.
19 . The BS of claim 15 wherein said digital video transmissions are wireless digital multimedia broadcasts (DMB).
20 . The BS of claim 15 wherein the back-channel connection is through a wired and/or wireless network.
21 . The BS of claim 20 wherein the back-channel connection is through the Internet.
22 . The BS of claim 20 wherein the back-channel connection is through a cellular network.
23 . A system for receiving wireless digital video transmissions over a WLAN comprising:
a base station (BS) adapted to provide a conditional access back-channel connection to one or more service providers; and
a mobile digital video receiver (DVR) adapted to transmit a request for conditional access to the BS.
24 . A method for receiving wireless digital video transmissions over a WLAN comprising:
adapting a base station (BS) to connect with one or more service providers via a conditional access back-channel connection; and
adapting a mobile digital video receiver (DVR) to transmit a conditional access request to the BS.
