Data alignment implemented in a field programmable gate array (FPGA) device
In an FPGA device, an FPGA receiver is configured to receive a serial signal, to deserialize the received serial signal into a parallel signal, and to align parallel words in the parallel signal. Programmable FPGA fabric in the FPGA device is coupled to receive the parallel signal from the FPGA receiver. The programmable FPGA fabric is also configured to descramble data words from the parallel words in the parallel signal, to perform a phase detection operation based on the descrambled data words, to generate an alignment control signal based on the phase detection operation, and to feed back the alignment control signal to the FPGA receiver to control alignment of the parallel words in the parallel signal. The serial signal is a Serial Digital Interface (SDI) signal in an embodiment.

Transmission of audio stream together with video data
The present technology relates to a signal processing apparatus, a signal processing method, a program, and a signal transmission system realizing an SDI (serial digital interface) capable of effectively transmitting an audio stream together with video data, for example, of which the frame rate is 100 Hz or 120 Hz. An audio multiplexing unit multiplexes an audio sample into a data area of horizontal lines of n2 (here, 2n2n1) rows after a first horizontal line in which the audio sample is generated, which is a predetermined data area arranged within a horizontal blanking area disposed for each horizontal line of video data in a data stream defined in a format of an SDI used for transmitting the video data, in a case where an audio is sampled at an interval of once or less for horizontal lines of n1 (here, n12) rows of the video data of a predetermined frame rate. For example, the present technology can be applied to a broadcast camera.

METHOD, SYSTEM AND APPARATUS FOR TRANSMITTING INTELLIGENT INFORMATION
Embodiments of the present disclosures provide a method, system and apparatus for transmitting intelligent information. When one frame of video data x is to be transmitted, a SDI sending terminal determines whether there is intelligent information satisfying a transmission condition; the transmission condition comprising that intelligent information is not transmitted and transmission of a frame of video data corresponding to the intelligent information is finished. If there is the intelligent information satisfying the transmission condition, the SDI sending terminal adds intelligent information y being one item of the intelligent information satisfying the transmission condition into a preset position of the video data x; and transmits the video data x having the intelligent information y. By using the solutions of the present disclosures, implementation costs are reduced and security is improved.
Method and Device for Mapping a Data Stream into an SDI Channel
The invention provides a method for mapping a data stream onto an SDI channel, said data stream comprising a sequence of m-bit words, a range of values from 0 to 2**n1 and from 2**m2**n to 2**m1 being excluded values on said SDI channel. The method comprises the steps of grouping the words to be transmitted, detecting if at least one of the words of the group contains a number of MSB's equal to one, and then recoding these MSBs and adding a constant, in order that no excluded values are obtained. Supplementary bits signal groups that have been recoded.
