In these years, if you want to engage in streaming media, you can't do it with the performance of your computer at home.

Although in this era, there are already streaming online videos, but this and live broadcast are two different concepts.

In fact, this year, the biggest obstacle to watching live broadcast is not the problem of bandwidth, but the problem of this year

But Senxia retreated and adopted another way, and it will not increase the burden on the live broadcaster's computer at all.

To put it simply, Senxia's method is as follows: the player's own machine will not have any video information, but will send instructions to the official platform, which is the same as the "audience viewing" in Warcraft 3 or other similar games.

And the one who is really responsible for broadcasting this part of the content is the "audience" at the other end, but this audience is more special, this is the official platform. And what the audience sees is not the player's computer itself, but the official computer.

Senxia has tried live streaming before, and this method is also officially explored now.

And the reason why Isaac is used as a game is also for a reason, because this one is very ornamental, and if you play well, you can make people die in a hurry, and if you play well, you can feel that you can also be chic.

And more importantly, even if you watch the live broadcast, the combination of Isaac is not tired of watching - because every game is a new experience.

Of course, there is another reason, that is, this game has very low requirements for color, and when playing as a streamer, the bitrate can be reduced as much as possible, reducing the picture requirements. Especially for the color part, when Isaac's binding is the lowest, it can drop to 256 colors, and the bandwidth requirements will be very low at this time.

256 colors are eight-bit colors, while sixteen-bit enhanced colors are 65536 colors, and as for true color twenty-four bits, that is 16777216 colors, which have great requirements for graphics cards and bandwidth.

For example, the size of a bitmap is the pixel of the map multiplied by the bit depth divided by eight, for example, a 1024×1024 resolution image uses 256 colors (octet), then the size of the picture is 1024×1024×8/8, the unit is bytes, if it is converted to a megabyte, it is exactly 1MB, and if it is true color, it is 3MB.

As for other JPG and other images, it's essentially a variety of compression algorithms for bitmap files, or adding some extra information on top of them, and so on.

This method is a compression algorithm that Company A came up with after studying it for a long time.

At the beginning,A company considered the degree of reducing the video bitrate,But there is a difficulty in doing this,That is, when the video bitrate drops,The picture will be easy to blur the screen,And if the resolution is reduced,It will make the picture unrecognizable。

Video bitrate is roughly the number of frames × resolution× quality, divided by 1024 plus the audio bitrate.

720P resolution,In the state of maintaining a certain quality,If the bandwidth is 2M (that is, 256KB)The download speed,It's basically able to watch.。

But herein lies the problem.

Because 2M...... This is already the "high-end" Internet in this era.

Compared with the 50M or 100M optical fiber in the future, the speed of this network is really not enough.

However, it is generally believed that Mori Xia's idea is not wrong.

According to the research done by Company A, they found that the network speed of mud bombardment is increasing rapidly, and the Internet is being vigorously built everywhere, so it is necessary to seize the opportunity.

Therefore, they thought of this degree of retreat and occupy the pit first before speaking.

Thankfully, most of the games in this year have 8-bit color display — including games like StarCraft.

Moreover, DC-P itself also has its own unified color chart, and when developing games and porting games, the colors of game manufacturers need to comply with this specification, so this reduction is acceptable.

In fact, in order to maintain a high frame rate, some games will also drop the color from the original 24-bit color to 16-bit color or 8-bit color in some scenes, and the resolution will also drop significantly.

Well, the so-called optimization ...... That's it.

Senxia sometimes does this kind of optimization.

For example, during a moonset, the game's graphics are scaled down and then expanded to full width through interpolation...... WELL, THIS IS THE SAME AS THE DEGRADED QUALITY FORCED INTERPOLATION OF XBOX WITH ANOTHER WORLD LINE. ON XBOX, THERE ARE MANY GAMES THAT CLAIM TO BE "FULL HD", BUT IN FACT, THESE GAMES ARE FORCIBLY STRETCHED AND INTERPOLATED WITH LOW RESOLUTION, WHICH IS FAKE HD. And they also made a bad start, that is, to let this kind of fake HD appear in piles and piles, which is really the initiator.

Well, the employees of Company A, who have learned the special abilities of the "descendants" of another world line without a teacher, are gratifying, gratifying~

By the way, some games on the other world line can be set to 16bit and 32bit, the former has better smoothness, but 8bit basically does not...... Because in the games of that era, if you changed to 8bit, many of the graphics would be worse......

Not only can the game be shrunk here.,The reason why the video can also be shrunk.,It's because it has its own specifications.,So when the video,It's down to 256 colors.,The picture can still be passable.。

According to this algorithm, Company A successfully made the 1M network also able to get a good video streaming experience.

- Of course, the best way to experience it is to use pre-installed live streaming software, download the game material package, and then get the best experience through a similar way to in-game recording, theoretically speaking, this way is the best, because there will be absolutely no loss of the picture, because these videos, sent from the Internet, are actually "instructions" and "information", and the picture of the video actually depends on the player's own adjustment of the game settings.

Of course, this mode also has a flaw, that is, it can only broadcast "official content", which is not supported if the game has MOD and other requirements. Only a real local live broadcast can reproduce the effect of the live broadcaster himself.

Well, it would be nice if there were more subtitles, but now there are no subtitles, only the spit box on the right side of the screen.

"This is a live stream?"

The release of the game is actually approaching now.

After discovering that the time was about the same, Senxia took Alice to watch the live broadcast together.

There are two live streams, one is an in-game video played with DC-P.

The other live broadcast is on the computer, using a video stream to broadcast live.

On two computers, Isaac's program was playing at the same time.

The live broadcast was an anchor named "Tanuki".

This brother was the first on the Isaac Ladder at the time of the beta version.

At that time, the game also underwent a round of playback testing, and according to the official vote at the time, this streamer with the ID of Tanuki was one of the most popular streamers of the game.

Moreover, compared with games such as Dark Souls, the durability of Isaac's union is obviously higher.

Because the game of Dark Souls, although it is very difficult, after playing for a period of time, the content in it is repeated, and it is not interesting.

On the contrary, games like this one can be experienced in a new way all the time, because each game has a completely different experience.

Sometimes, players can get the best treasures in the game, such as Sacred Heart, Divinity, etc., so as to crush the game.

Sometimes, the player can get some kind of car or Dead Sea Scroll with a very uncertain effect, making what will happen in the next second of the game into an interesting scene that is unknown for no reason.

There are also times when players find that there are negative treasures that they can't take along the way, so they suffer all the way to the end.

"Is this a new game?"

At this time, Yukino also came over with Matomi.

She also had a tray in her hand.

On the tray are two cups of green tea and a stack of dumplings.

"Hmm. Senxia nodded, then said, "A new game that has just begun." ”

"Player feedback has been good. At this time, Alice has been looking at the feedback in the chat box next to her.

Many players have reported that this form of live broadcast can let people know whether the content of the game is fun or not before playing the game.

"However, there are also concerns that many people will not play games after watching videos......

Alice found that there were also concerns that someone would not play the game after watching the video.

Although it is a study, this place is actually quite large, and after four people came in, it was actually not very crowded.

"Ah, don't worry about it, the person who doesn't buy the game because he will go to the video clearance, even if he doesn't have the video, he won't buy the game. "And those who don't know the game, after watching the game, may buy it, and this model will also be very effective for improving the reputation of the game." ”

"Hmm...... You're right to say that. ”

Many people who have cleared the video game, if they don't have the video, they probably won't play the game themselves, and there are many reasons for this.

Some people get dizzy when they play a game.,But it's no problem to watch videos.,Some people are handicaps.,I can't play the game at all.,But it's very enjoyable to watch others play.,And some people are passing by the soy sauce party.,Purely come in to watch the anchor's talk show and mentally retarded operation.,But there's no interest in the game itself.。

These people themselves don't have much passion for games.

"What about story-oriented games, like galgame?" Alice asked again.

"That kind of game belongs to the genre of pure watching live broadcasts and playing them yourself. "We've done research and found that text-based games are more likely to be played by themselves than RPGs or action games. For games that are more interactive, or prone to embarrassment, players tend to watch others play. ”

"And don't you think watching others play galgame, there is a feeling of being NTR?"

"Well, that's a good feeling, I think you can play it, and if there's a game of Darling, that's even better. ”

"Uh-" Senxia rolled her eyes at Alice.

This guy is just so unreliable sometimes.

"It's ugly, but I think it's a little cute......" Hitomi wasn't very interested in the game, but after hearing that she had been complaining here, she also looked towards the screen.

How to say it, the bald "Isaac" on the picture really has a very good feeling.

Although the whole picture has a strange atmosphere, Isaac, as the protagonist, at this moment, also has a feeling of ugliness and cuteness.

"This game is called the Binding of Isaac. Mori Xia introduced the game to Hitomi, "It's an interesting game, do you want to try it?"

The reflex nerve of the true pupil is very good, which can be regarded as the TOP level of a normal person...... Well, Lihua's kind of over-spec doesn't count, and the adults will not have a positive evaluation of the game.

"Huh, is that okay?" Hitomi asked curiously.

"Ah, of course it's no problem, I'll take a look......" Senxia has three computers here, because these computers are not only used to check information, but some also need to conduct some tests, plus there are many people in the family, so one computer is not enough.

He turned on another computer and logged into the Mithril platform.

"Well, the effect of DC-P is actually better, but I only have one DC-P here, but playing with a computer, the effect is not bad. ”

The combination of Isaac is a multi-platform game...... Well, PS2 is discriminated against on a daily basis because it doesn't support mods and DLCs.

The game's icon is on the desktop, so the real pupil clicks on it and enters the game.

"I'm going to try it too!" Alice immediately offered to try it as well.

"That computer, turn on itself. Senxia pointed to another computer next to him.

Then he noticed that Alice was looking at him with resentment.

Well, she and Makotomi, the treatment of the two people is really completely different.

When Alice also went to play the game, there were only two left, Mori Xia and Yukino.

"Why are the pictures all the same here?" Yukino noticed that the pictures of both were the same, and Mori Xia had used a pause to synchronize the two images.

"Don't you see the difference?" said Mori Xia with a smile.

"Hmm...... Feel like the DC-P picture is clearer, right?" Yukino tilted her head.

"Well, that's pretty much it, but what about the viewing experience?"

"It's all right. Although there is a gap, it is not a big one. ”

"Ah, that means we've succeeded. Senxia chuckled, "If the live stream is successful, it means that we are very successful now, and this is exactly what I need." ”

If the live broadcast can be successful, Senxia feels that it may be time for him to start preparing for an online video platform at this moment.

It just so happens that Hatsune Miku's plan can take the lead.

Well...... Niconico or something, perhaps...... Well, we can make a mikumiku~

The development of the mud bombardment network is much faster than that of a large eastern country, but the activity of the mud bombardment network is unexpectedly not as good as that of a large eastern country, but Senxia feels that he may be able to toss it.

Of course, don't think about the barrage or anything, if you really want to do a barrage live broadcast this year, I'm afraid that the computer will explode immediately.

In 2001, the rapid development of mud bombardment network development is in full swing, and the network speed will soon not be a problem, the problem is hardware.

"Hmm...... ......Maybe we can cooperate with manufacturers?" What about hardware decoding?

Senxia stared at the screen on the computer, and then thought about the next step in his mind.

......

By the way, if you want to know what a 256-color video looks like, it's good to recall a lot of gif pictures, because many pictures are 256 or 16 colors. But the effect of native and forced image quality reduction is different.
