USB video card and dongle device with video encoding and methods for use therewith
View Patent ↗A universal serial bus (USB) dongle device includes a USB interface for receiving a video signal in a first format and for sending a processed video signal in a second format wherein the first format differs from the second format. An encoding module generates the processed video signal based on the video signal. In a further embodiment, A video card includes a video receiver for receiving a video signal in a first format, based on a selection command. An encoding module generates a processed video signal in a second format based on the video signal, wherein the first format differs from the second format. A USB interface transfers the processed video signal to the host device, receives the selection command from the host device and receives a power signal from the host device to power the video receiver and the encoding module.
1. A video card for use in conjunction with a host device, the video card comprising:
a video receiver for receiving a broadcast video signal in a first format, based on a selection command that indicates a selection of the first format from a plurality of available formats;
an encoding module, coupled to the video receiver, that generates a processed video signal in a second format based on the video signal, wherein the first format differs from the second format; and
a USB interface, coupled to the encoding module, that transfers the processed video signal to the host device, that receives the selection command from the host device and that receives a power signal from the host device to power the video receiver and the encoding module.
2. The video card of claim 1 further comprising:
a memory module, coupled to the encoding module, for storing the processed video signal as a compressed video file; and
a playback module, coupled to the memory module and the USB interface, that retrieves the compressed video file from memory, that regenerates the processed video signal based on the compressed video file, and that the buffers the processed video signal for transfer to the host device.
3. The video card of claim 1 further comprising:
an electronic program guide module, coupled to the video receiver and the USB interface, that sends program data to the host device relating to a plurality of video programming selections;
wherein the host device generates the selection command based on one of the plurality of programming selections.
4. The video card of claim 1 wherein the video card further comprises:
a decoding module, coupled to the USB interface and the encoding module, that decodes the video signal from the first format to generate a decoded video signal;
wherein the encoding module generates the processed video signal by encoding the decoded video signal, and wherein the second format is at least one of, transcoded, transcaled, and transrated, from the first format.
5. The video card of claim 1 (previously presented) and the first format includes an encrypted digital format, and wherein the video card further comprises:
a decryption module, coupled to the USB interface and the encoding module, that decrypts the video signal from the first format to generate a decrypted video signal;
wherein the encoding module generates the processed video signal by encoding the decrypted video signal.
6. The video card of claim 1 further comprising:
an encryption module, coupled to the encoding module, that encrypts the processed video signal.
7. A method for use in a video card that is coupleable to a host device via a universal serial bus (USB) interface, the method comprising:
receiving a selection command from the host device via the USB interface;
wirelessly receiving a video signal in a selected one of a plurality of first video formats, based on the selection command that indicates a selection of the first format from a plurality of available formats;
generating a processed video signal in a second video format based on the video signal, wherein the first format differs from the second format;
transferring the processed video signal to the host device via the USB interface; and
receiving a power signal from the host device to power the video card.
8. The method of claim 7 further comprising:
storing the processed video signal as a compressed video file in a memory;
retrieving the compressed video file from the memory;
regenerating the processed video signal based on the compressed video file; and
buffering the processed video signal for transfer to the host device.
9. The method of claim 7 further comprising:
sending program data to the host device relating to a plurality of video programming selections;
wherein the host device generates the selection command based on one of the plurality of programming selections.
10. The method of claim 7 wherein the selected one of the plurality of first video formats includes a packetized digital format, and wherein the method further comprises:
decoding the video signal from the selected one of the plurality of first video formats to generate a decoded video signal;
wherein generating the processed video signal includes encoding the decoded video signal, and wherein the second video format is at least one of, transcoded, transcaled, and transrated, from the selected one of the plurality of first video formats.
11. The method of claim 7 wherein the selected one of the plurality of first video formats includes an encrypted digital format, and wherein the method further comprises:
decrypting the video signal from the selected one of the plurality of first video formats to generate a decrypted video signal;
wherein generating the processed video signal includes encoding the decrypted video.
12. The method of claim 7 further comprising:
encrypting the processed video signal.
