There are a number of different answers depending on how you measure a frame. Here are a few of them:
A frame of HD 1080i comprises two fields and is repeated 25 (Europe) or 29.97 (North America) times each second. A 25 FPS frame can contain up to 7.4MB of data. A 29.97 FPS frame can contain up to 6.2MB of data. These are based on an HD digital signal data rate of 1.483 gigabit per second which is the broadcast standard data rate.
Each complete frame of broadcast standard HD at 1080 resolution contains about 5.2MB of data. The additional data mentioned above of 6.2MB and 7.4MB of data allows space for audio and other data to be carried as part of the signal.
The other broadcast HD signal is 720p. It is progressive and not interlaced so the question doesn't strictly ask for information on the format. The format has an image of exactly half the resolution but runs at twice the frame rate. The data rate remains identical to a 1080i signal although each frame is about 2.6MB of image data, allowing space in the data stream for twice the number of frames.

What is the difference between a field and a frame?
A field is one of the interlaced lines that make up a video frame. A frame is a complete still image that contains all the fields. Frames are composed of two fields for interlaced video, whereas frames for progressive video contain all the image data in one frame.
Which frame field is created by a source node and used by a destination node to ensure that a transmitted data signal has not been altered by interference distortion or signal loss?

What causes frame errors?
Frame errors are typically caused by issues in data transmission, such as signal interference, noise, or signal degradation over distance. These errors can also result from improper synchronization between sender and receiver, leading to misinterpretation of the data frames. Additionally, hardware malfunctions or packet collisions in network environments can contribute to frame errors, impacting overall communication reliability.
What is the basic block diagram of a synchronous frame?
A basic block diagram of a synchronous frame typically includes several key components: a data source that generates the information to be transmitted, a synchronous transmitter that encodes this data along with a clock signal for synchronization, and a communication medium (like a cable or wireless channel) that carries the signal. On the receiving end, a synchronous receiver decodes the received signal using the clock signal to accurately extract the data. Additionally, there may be error detection and correction blocks to ensure data integrity during transmission.

What is interlaced memory?
Interlaced memory is a technique used in computer memory systems where data is divided into multiple segments or "interlaced" across different memory banks or modules. This method allows for improved access speed and efficiency, particularly in applications that require high bandwidth, as it enables simultaneous access to multiple memory locations. By spreading data across different paths, interlaced memory can reduce bottlenecks and enhance overall system performance. It is often utilized in graphics processing and high-performance computing.
What is encoding technique?
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
Distinguish between a signal element and a data element?
Signal Element Versus Data Element: Let us distinguish between a data element and a signal element. In data communications, our goal is to send data elements. A data element is the smallest entity that can represent a piece of information: This is the bit. In digital data communications, a signal element carries data elements. A signal element is the shortest unit (time wise) of a digital signal. In other words, data elements are what we need to send; signal elements are what we can send. Data elements are being carried; signal elements are the carriers.

What is the difference between 1080i and 1080p signals?
Television images are made of horizontal lines. 1080 indicates that the image is a high definition one and uses 1080 lines to create the image. The "i" and "p" define how the lines will be delivered. "i" stands for interlaced. An interlaced picture will start by showing all the odd numbered lines from 1, 3, 5 etc to line 1079. Then, starting at the top of the screen, all the even numbered lines will be shown from 2 to 1080. so in two passes from the top to the bottom, every line will be shown. the passes each happen 50 or 60 times each second so a full frame will be shown 25 or 30 times each second. "p" stands for progressive. A progressive scan starts at the top of the screen and shows each line in order from line 1 to line 1080. A single pass is all that is needed to build a full image. That means that a full frame will be delivered 50 or 60 times each second. It is easy to see that a progressive signal displays lines at twice the rate of an interlaced signal. It therefore needs to send twice as much data as an interlaced signal. Broadcasters do not transmit 1080p at the moment and are unlikely to do so for at least a few years. The standard broadcast HD signals are 1080i (and 720p). Most HD televisions will handle 1080p signals but they are found only on local sources such as Bluray, games consoles and computers. In practical terms, the difference between "i" and "p" is that progressive signals show smoother movement compared to interlaced. For most programs, the difference is not obvious so the lack of a 1080p signal from broadcasters is not a big deal. A final note on the frame rates: North America uses a 60Hz rate as standard while Europe uses 50Hz. The reason is a historical one but the frame rates will not be changing for either region any time soon.
What is modulation in data communication?
Data modulation is a method of Electronic packing of data. In Data communication data is transmitted through a process which is called "Data Modulation".
What is the function of an ACK in Stop-and-wait error control?
In Stop-and-Wait error control, an ACK (Acknowledgment) is sent by the receiver to confirm successful receipt of a data frame. It serves as a signal for the sender to proceed with sending the next frame. If the sender does not receive an ACK within a specified time frame, it assumes the frame was lost or corrupted and retransmits it.
