ltc time code how much is this apple

❶ How much does an iPhone generally cost

Apple phones are generally around 6 to 9,000 yuan, depending on the model and configuration and whether it is new.

❷ How much does the Apple 13 cost?

The iPhone 13 is not particularly expensive. If it is cheap, you can buy it for five or six thousand. If you want to buy a more expensive iPhone, it is only about 10,000 yuan, not more than 10,000 yuan, and the most expensive one is only more than 10,000 yuan. Therefore, the price of the iPhone 13 is different. It is based on the memory of the phone. There is also a price based on its performance.

❺ Hurry up! Does anyone know the encoding method and decoding method of LTC time code?

Time encoding

First, the concept

Here we want to explain the media stream An important concept in processing – time encoding.

Time encoding is an auxiliary data for video and audio streams. It is contained in video and audio files, which we can understand as timestamps.

SMPTE timecode is the sum of a SMPTE time and control code, which is a continuous digital address frame, flags and additional data in a video and audio stream. It is defined in ANSI/SMPTE12-1986. Its purpose is to provide a computer-processable video and audio address.

The maximum SMPTE time code data structure is a 80-bit frame, which contains the following contents:

a, a hh::mm::ss::ff ( Timestamp in hour::minute::second::frame) format.

b. Eight 4-bit binary data are usually called “user bits”.

c, Different Flags

d, Sync Sequence

e, Verification Sum

This format is used in DirectShow is defined as TIMECODE_SAMPLE.

The time code is divided into two forms, one is the linear time format LTC (Longitudinal Coding), each time code represents a frame in continuous time. Another type of timecode is VITC (transverse coding), which stores two lines of the video signal in a vertical blanking interval, somewhere between 10 and 20.

LTC timecode is very easy to add to eg videotape because it is encoded as a separate audio signal. But it cannot be read while the tape drive is paused, slow-forwarded, or fast-forwarded. In addition, in non-professional video recorders, it may lose an audio signal.

VITC timecode is different from LTC in that it can be read at 0-15x speed. It can also read from video capture cards. But if it is to be recorded to tape, it may require some additional equipment, which is usually more expensive.

SMPTE time code supports two modes at the same time, one is non-drop frame mode and the other is drop frame mode. In non-drop frame mode, the timecode is recorded in continuous increments. It can complete real-time playback work up to 30 frames, or higher.

The video playback standard of the NTSC system is 29.97 frames per second, which is due to the compatibility of the monochrome TV system. This leads to a question. In non-drop frame mode, there will be 108 frames out of sync in one hour, that is, when one hour is in real time, the time code is only read 00:59:56:12. When you calculate There are some issues with streaming playback time. In order to solve this problem, we can skip the frame implementation when it can be tolerated. This is achieved by skipping two frames at the start of each minute count but not skipping frames at 00, 20, 30, 40, and 50 minutes. Using this scheme, the error of our network test results is less than one frame per hour, and the error is about 3 frames per 24 hours.

In the actual work now, although both modes are provided at the same time, the frame-dropping mode is usually adopted by us.

Second, the typical application of time code

Controlling peripheral devices for video capture and editing is a typical application. Such applications need to identify each frame of video and audio frames, and the method they use is to use SMPTE timecode. Linear editing systems typically control three or more tape drives and switch video between disc recorders as much as possible. Computers must be precise�� execute the command, so the address of the specified position of the tape must be obtained at a specific time. Applications can use timecode in a number of ways, mainly the following:

a. Track video and audio sources throughout the editing process

b. Synchronize video and audio.

c. Synchronize multiple devices

d. Use undefined bytes in timecode, called: userbits. This usually contains the date, ascii code or industrial information about the movie etc.

3. Capture time code

Usually, time code is generated by some capture card devices capable of generating time code. For example, an rs-422 requires time code to control peripherals and host communications.

After the time is generated, we need to get the timecode from the video and audio in stream format, which can be accessed later. Then we process the time code through the following two steps:

a. Establish a non-consecutive index of each frame position, and associate the time code with each frame one-to-one. This list is written at the end of the file after capture is complete. The list can be an array of matrices like the structure below, provided here is just a simplification of the DirectShowTIMECODE_SAMPLE structure for brevity.

struct {
DWORD dwOffset; // offset bits in frame
char[11] szTC; // value of timecode in offset value
// hh:mm:ss:ff is a non-drop frame format hh:mm:ss;ff is a drop frame format
For example, here can give a video capture stream in Timecode for:

{0, 02:00:00:02},
{16305, 15:21:13:29} // Time format at frame 16305

Using this table, the timecode of any frame will be calculated just fine.

B. Another way is to write the time code as video and audio data. We do not recommend this kind of use and therefore will not be introduced.

The files written in the timecode can be edited, composited, synchronized, etc. This is written here, enough for us to understand timecode. Many others are about the introduction of the standard, you can refer to it if you are interested.
