Abstract

The present disclosure relates to devices comprising small form factor pluggable units (SFP) having connectors for receiving and sending signals and a processor for converting the received signals prior to sending the converted signals. Received or sent signals may comprise video signals in various analog or digital formats. Conversion of the received signals may comprise analog to digital or digital to analog conversion, serializing or deserializing a digital signal, frame synchronization of a video signal, and/or cross conversion of a video signal from a first format to a second format.

Claims

1. A small form-factor pluggable (SFP) unit comprising:

a housing having specific standardized SFP dimensions and adapted to being inserted into a chassis of a hosting unit;

a first bidirectional connector on a front panel of the housing for receiving a video signal;

an analog to digital convertor (ADC) in the housing for converting the video signal into a digital signal;

a serializer module in the housing for transforming the digital signal into a serial data signal; and

a second bidirectional connector on the front panel of the housing for outputting the serial data signal.

2. The SFP unit of claim 1, wherein the video signal is one of the following:

a National Television System Committee (NTSC) signal, a Phase Alternating Line (PAL) signal, a Sequential Color with Memory (SECAM) signal, and an analog signal of a Red Green Blue (RGB) format.

3. The SFP unit of claim 1, comprising a processor for treating the digital signal before serializing.

4. The SFP unit of claim 3, wherein treating the digital signal comprises an element selected from the group consisting of filtering, emphasizing, de-emphasizing, de-jittering and de-aliasing the digital signal.

5. The SFP unit of claim 1, wherein the first bidirectional connector is one of the following:

a co-axial cable connector, a optic fiber connector, a Separate Video (S-Video) connector, a composite video, blanking and sync (CVBS) connector, a Radio Corporation of America (RCA) connector, a Bayonet Neill-Concelman (BNC) connector, a Video In Video Out (VIVO) connector, a YP_BP_R connector, a mini Video Graphics Array (VGA) connector, a TV Aerial Plug, and a mini-DIN (Deutsches Institut fü

r Normung) connector.

6. The SFP unit of claim 1, wherein the second bidirectional connector is one of the following:

_a co-axial cable connector, a optic fiber connector, a Universal Serial Bus (USB) connector, a Serial Digital Interface (SDI) connector, a BNC connector, a mini VGA connector, a High-Definition Multimedia Interface (HDMI) connector, and a mini-DIN connector.

12. The SFP unit of claim 1, wherein the video signal is one of a standard definition television (SDTV), enhanced definition television (EDTV) and high definition television (HDTV), and the second format is another one of SDTV, EDTV and HDTV.

13. The SFP unit of claim 3, further comprising;

a timing source in the housing; and

wherein the processor applies frame synchronization to frames of the video signal based on the timing source.

14. The SFP unit of claim 13 wherein the timing source comprises an internal clock.

15. The SFP unit of claim 13, wherein the timing source comprises a third connector for connecting the SFP unit to a timing reference of the chassis.

16. The SFP unit of claim 13, wherein the timing source comprises a third connector for connecting the SFP unit to an external timing reference.

7. A small form-factor pluggable (SFP) unit comprising:

a housing having specific standardized SFP dimensions and adapted to being inserted into a chassis of a hosting unit;

a first bidirectional connector on a front panel of the housing for receiving a serial data signal;

a deserializer module in the housing for transforming the serial data signal into a digital signal;

a digital to analog convertor (DAC) in the housing for converting the digital signal into a video signal; and

a second bidirectional connector on the front panel of the housing for outputting the video signal.

8. The SFP unit of claim 7, wherein the video signal is one of the following:

a National Television System Committee (NTSC) signal, a Phase Alternating Line (PAL) signal, a Sequential Color with Memory (SECAM) signal, and an analog signal of a Red Green Blue (RGB) format.

9. A conversion device comprising:

a small form-factor pluggable (SFP) unit comprising;

a housing having specific standardized SFP dimensions and adapted to being inserted into a chassis of a hosting unit;

an analog to digital convertor and digital to analog convertor (ADC/DAC) in the housing for converting a signal between an analog format and a digital parallel format,

a serializer and deserializer module in the housing for transforming a digital signal between the digital parallel format and a serial format,

a first bidirectional connector on a front panel of the housing for receiving a video signal according to the analog format, and

a second bidirectional connector on the front panel of the housing for sending a data signal according to the serial format.

10. The conversion device of claim 9, wherein the serializer and deserializer module comprises separate modules for transforming the digital signal from the digital parallel format to the serial format and for transforming the digital signal from the serial format to the digital parallel format.

11. The conversion device of claim 9, wherein the serializer and deserializer module is formed of a dual-purpose module.
